ARMRA Review

We all experience aches and illnesses, and the desire for better health is only natural. To that end, many people strive to exercise, eat better, and cut out the bad stuff from their lives. Often, too, they turn to supplements to help them along their health journey.

Colostrum is one category of supplements that has gained traction in recent years. In its raw state, colostrum is known as the initial milk secretion that lactating mammals produce for their offspring. As a supplement for human use, it’s usually derived from cows and dried into a powder. In either form, it’s rich in the compounds needed for newborns to develop their immune systems. Seeing as more than 83% of infants start out on breast milk, chances are that you've consumed colostrum at some point in your life.1

ARMRA is one of the few supplement companies on the market that deals exclusively in colostrum and colostrum-related products. We tried its colostrum powders ourselves — and studied the relevant scientific research — to help you determine whether it deserves a place in your health and wellness regimen.

ARMRA's bovine colostrum products include high concentrations of bioactive compounds supported by research to potentially improve gut health, immune health, and performance recovery. ARMRA uses a low-temperature pasteurization method to preserve the composition of these compounds, which is consistent with studies on how temperature impacts colostrum’s most important nutrients. Also, from our research, the quantity of helpful compounds found in Health Revival and Performance Revival may be sufficient to help the body ward off pathogens, reduce inflammation, or delay fatigue. The company’s up-front price points are steeper compared to other colostrum supplements, but given the large serving count in every container, the per-serving costs are comparable to those of competitors.

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

To give you a complete view of ARMRA's health applications, efficacy, and safety, our team spent over 60 collective hours closely examining 50 studies, reviews, and various reputable sources on bovine colostrum and the other ingredients found in ARMRA's colostrum products. Where applicable, we reached out to ARMRA and its direct competitors to verify areas of uncertainty, and we performed hands-on testing — including tasting the various flavors — to familiarize ourselves with the products and the ARMRA customer experience. Since first publishing this review, we’ve also followed the ARMRA brand to take note of what’s changed and how it holds up in the colostrum space.

Like all health-related content on this website, this review was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

To evaluate ARMRA, we centered on factors that would normally influence a person’s decision to try a supplement: efficacy, cost, safety, and customer experience. We considered taste to be a key criterion, too, as ARMRA's use as a food or drink additive means its flavor is likely to affect your overall impression.

Here’s how ARMRA looks in each category:

Efficacy

The generally accepted metric for determining colostrum efficacy is a minimum 5% concentration of immunoglobulin G (IgG), an essential protein for building one's overall immunity.18 In response to a customer question on Amazon, ARMRA states its colostrum products have an IgG concentration greater than 40%, but a response we received through the company’s customer support portal indicated "no less than 35%." That means ARMRA has more IgG than Miracle Moo (30%), but possibly not as much as WonderCow or Adapt Naturals (both 40%). With that being said, ARMRA uses a patented pasteurization method that could, in theory, raise its bioactive potency above that of competitors. And at any rate, a single serving of ARMRA is well above the 5% standard for efficacy in providing colostrum’s purported health benefits, such as improved gut and immune health.20

We should mention, too, that ARMRA claims its colostrum contains high concentrations of immunoglobulin A (IgA), which is critical for fighting off pathogens in mucosal linings, like in the intestines and lungs.19 While a high IgA concentration would support ARMRA's claims that its products support immune and gut health, the company doesn’t specify how much IgA its colostrum contains — for that matter, neither do Miracle Moo or WonderCow — so we can’t say for certain whether ARMRA’s IgA concentration is higher or lower than its competitors’.

ARMRA's Performance Revival formula also contains ingredients that show promise for use among athletes. Namely, black cumin and tart cherry have anti-inflammatory and antioxidant properties, which may help reduce the fatigue and inflammation resulting from strenuous activity.25 26 Tart cherry may also promote sleep health by elevating the body's levels of melatonin, a molecule that regulates sleep patterns.27 None of ARMRA's top competitors, direct or indirect, offers a product formulated for these outcomes. With that being said, Performance Revival appears to be underdosed, so its potential benefits may be limited.

Cost

Cost is a common complaint among ARMRA customers, and the company's products are decidedly more expensive up front than those of most competitors. At its discounted subscription price, ARMRA's Unflavored Health Revival bulk jar costs $104.49, whereas a WonderCow subscription is almost half as much.

At the same time, a single jar of ARMRA contains more servings than its competitors provide. In fact, the Unflavored variant has up to twice as many servings as WonderCow, so its per-serving price is actually lower: $0.87 versus WonderCow’s $0.92. There’s now even an ARMRA XL jar whose price tag equates to only $0.79 per serving, and ARMRA’s Unflavored Travel Sticks also cost a little less up front than their WonderCow counterparts.

Additionally, we recognize that ARMRA has several distinguishing characteristics that may justify the higher up-front price tag for some buyers. One is its high IgG concentration and theoretical efficacy preserved by the company’s patented pasteurization method. Another is that its products (purportedly) contain no casein, so they could be suitable for people with a casein allergy. And a third factor is variety: ARMRA's product line includes a wider range of flavors than most of its competitors, plus a performance-oriented formulation that’s unique to the company. Admittedly, though, ARMRA’s flavored powders are pricier than its Unflavored products, and are, therefore, less cost-competitive.

Safety

To date, no studies indicate that bovine colostrum poses specific dangers to the general public, so ARMRA is clear on that front. Colostrum, however, is a dairy product, so the primary concern relates to people who are allergic to casein and whey, the two main dairy proteins. Casein might be a non-issue here, as ARMRA (like WonderCow) claims to remove casein from its products during pasteurization. But whey remains a problem; if you’re allergic to whey, you should refrain from using ARMRA and other colostrum products to avoid the risk of anaphylaxis.

Lactose is another concern, but it’s not as worrisome as you might imagine. A serving of ARMRA contains only 1g of lactose, whereas people with lactose intolerance can often tolerate up to 12 times as much.8 With that said, the best approach for lactose-intolerant users is to be cautious and take a lactase supplement to prevent potential discomfort.

Be aware that flavored ARMRA products do contain ingredients apart from colostrum (e.g., annatto extract, dragon fruit, stevia). These particular products may cause mild-to-severe symptoms in people with related allergies or intolerances, for whom the Unflavored variant would be the better (or only) choice.

As for operational practices, ARMRA looks solid. For example, its colostrum is manufactured in FDA-registered facilities in compliance with Current Good Manufacturing Practices (cGMPs), which assures adequately controlled operations and a product that meets standards of "identity, strength, quality, and purity."2 ARMRA also claims to audit every production, and its colostrum is sent for testing at third-party ISO/IEC-certified laboratories before being made available for purchase. Compare that with Miracle Moo, for which an ongoing class-action lawsuit casts doubt on the company’s claims of testing its products.45

Taste

Because ARMRA is meant to be mixed into food or drinks, its taste will play a significant part in your enjoyment. Fortunately, ARMRA does well on this front, and not only because its flavor line is more diverse than that of most competitors. The Unflavored variant tastes about equal to other colostrum powders — faintly milky, kind of savory — which is no knock on it. We think most users will find it a decent complement to smoothies and certain (cold/cool) dishes. WonderCow, in comparison, leans ever so slightly toward “sweet,” and we enjoyed it best in other products containing milk or milk alternatives.

ARMRA’s Blood Orange, Vine Watermelon, and Peach Persimmon flavors are quite tasty in water alone, and we enjoyed sipping them. The only product that didn't appeal to our tastes was Performance Revival. Available in Chocolate only, it has a bitterness and strong stevia flavor that may not be pleasurable to everyone’s palate. The flavor also limits what it can be mixed into.

Customer experience

Whether it was ordering, managing our subscription, or corresponding with a representative, ARMRA provided us with an excellent customer experience.

With regard to customer support, we appreciate that ARMRA has added a live chat widget to its communication channels. It allowed us to resolve inquiries in minutes rather than the hours or days we needed with competitors WonderCow and Miracle Moo. Each of our chats ended satisfactorily, too, and was accompanied by a transcript in our email inbox.

We also found subscription management to be straightforward. The ARMRA dashboard is easy to navigate and displays options to pause or cancel your subscription near the bottom of the page. If you cancel your subscription, ARMRA will offer ways to retain it, but these barriers are understandable, minor, and quick to hurdle.

Founded in 2020, ARMRA is a Florida-based health brand specializing in powdered bovine colostrum supplements. Colostrum is the first form of breast milk that mammals produce 2-4 days after giving birth. It differs from mature milk in not only its thicker consistency and rich, yolky color but also its composition. Specifically, it has higher levels of essential compounds that support a newborn's physical and immunological development.3 4 As a supplement for human use, colostrum normally comes from cows (bovine colostrum), as is the case with ARMRA. It’s generally suitable for people of all ages. Because of its potential health benefits, it falls under the broad and nebulous category of “superfood.”

Aside from branded merchandise, carafes, and frothers, ARMRA's product line comprises two lines of dissolvable powders:

Whereas Performance Revival comes exclusively in a 120g bulk jar, you can purchase Health Revival in one of two jar sizes or a 30-count box of travel-size packets — similar to WonderCow.

A serving size of ARMRA is one scoop of bulk powder or one stick pack. You may want to start at a single serving per day, but you're free to increase your dosage as tolerated. For reference, a 2003 review by neuropathic doctor Gregory S. Kelly found that successful trials of colostrum dosage used 10g per day for treating or preventing diseases and 60g per day for athletic performance.5

ARMRA’s pasteurization method

A point of distinction that ARMRA advertises is that it uses a proprietary low-heat pasteurization method called “Cold-Chain BioPotent” to concentrate its colostrum's nutrients and optimize absorption.

As with milk, pasteurization is necessary to neutralize the naturally occurring pathogens in colostrum. One method of pasteurization takes the colostrum above 160 degrees Fahrenheit to eradicate the pathogens in a matter of seconds. The alternative is to hold it around 140 degrees for a longer time, a method broadly known as low-temperature long-time (LTLT) pasteurization.44 ARMRA's Cold-Chain BioPotent method is a version of the latter.

A 2023 meta-analysis in the Journal of Dairy Science, which examined 45 peer-reviewed articles published between 1946 and 2022, seems to support a connection between LTLT pasteurization and superior nutrient delivery. The researchers found that newborn calves that were fed colostrum treated below the 140-degree threshold had higher serum IgG concentrations, which suggests a higher likelihood of imparting immunological benefits.6

Sourcing initiatives

ARMRA proclaims that it follows "responsible sourcing practices" for its colostrum, which means:

• Its colostrum comes from grass-fed cows on family-owned U.S. farms.
• The company follows a calf-first initiative, by which baby calves have first dibs on the colostrum, and only the surplus is used to make supplements.

This approach, which is similar to WonderCow's, is meant to drive sustainability in sourcing by preventing the deprivation of the calves that need colostrum to thrive and reducing product waste.

ARMRA’s brand reputation

ARMRA seems to have a complex brand reputation. Its page with the Better Business Bureau (BBB), active since 2023, reveals an F grade, a 1.14-star customer rating, a smattering of customer complaints, and a lack of BBB accreditation. At the same time, its Amazon pages convey high ratings and generally favorable experiences. So, to get a more accurate picture of how customers really view the company, we should take a closer look at each of these sources.

As of September 2025, ARMRA's BBB page indicates a total of 28 customer reviews, practically all of which are one-star ratings, along with 48 customer complaints within the last three years. The complaints primarily center on the inability to cancel subscriptions, unsolicited charges, or the absence of a refund policy — claims that aren't entirely inconsistent with our research. Evidently, ARMRA has stopped monitoring BBB as a gauge of customer satisfaction, as the last time it responded directly to a complaint was March 2024.

But ARMRA did issue a broad response to its customers in the preceding month, in which it attributed its shortcomings to rapid growth and attendant increased order volume. The company has since tried to make improvements through “logistics optimization,” “customer service enhancement,” and “technology upgrades.”

On Amazon, ARMRA features a few product pages for its Health Revival supplement (still pictured as “Immune Revival,” oddly). At the time of this writing, ARMRA’s Stick Pack has a 4.2 overall rating based on more than 4,500 reviews, while the bulk jar has a 4.3 rating based on more than 1,000 reviews (note: ratings and review numbers are subject to rapid changes). The negative reviews largely relate to a lack of results or adverse reactions that are common among most supplements (e.g., stomach pain, headaches), whereas the positive reviews describe improvements in areas such as energy and gut health.

Taken together, this disparity in impressions doesn’t necessarily reveal anything unique about ARMRA as a business. With just about any company, not everyone is going to have an overwhelmingly positive experience, and often a negative one is more likely to motivate a customer to leave a review.

Of note, however, high cost is a common complaint among both satisfied and dissatisfied ARMRA customers. We discuss the topic further in the section "How much does ARMRA cost?"

Both of ARMRA’s marquee products aim to address the following areas:

• Gut and gastrointestinal health
• Metabolism
• Energy
• Stamina and endurance
• Post-performance recovery
• Focus
• Skin health

So, with such a broad range of possible health benefits, ARMRA Health Revival can potentially benefit anyone looking to enhance their physical, cognitive, or aesthetic health, while Performance Revival might further support people who are physically active.

ARMRA's target audience includes people who are dairy intolerant, as its patented Cold-Chain BioPotent pasteurization method purportedly removes casein, one of the two milk proteins that can cause allergic reactions.7 Still, if you have a casein allergy, we recommend speaking with your doctor first. Also, ARMRA does contain whey (the other milk allergen protein), so don't take it if you're allergic to that.

ARMRA may likewise be suitable for the lactose-intolerant since a serving contains only 1g of lactose. Per the National Institute of Diabetes and Digestive and Kidney Diseases, many people with lactose intolerance can handle up to 12g of lactose at a time, so it may be possible to consume even large servings of ARMRA without any discomfort.8 That being said, some people are more severely lactose intolerant than others. If even trace amounts of lactose are enough to trigger your symptoms, you may be better off either taking a lactase supplement along with ARMRA or avoiding colostrum products altogether. At any rate, a doctor's consultation is recommended.

Other populations who may want to avoid colostrum supplement include:

Both of ARMRA's marquee products consist of concentrated bovine colostrum, which has a biochemical makeup similar to human colostrum. In its natural state, colostrum is like a vaccine for newborns. It contains heaps of bioactive compounds that, when consumed, help establish passive immunity — when antibodies are transferred into a body rather than produced by the body's immune system.11 Ingested as a powdered supplement like ARMRA, colostrum may impart a wide range of physical improvements by introducing more of these compounds to the body. As outlined in scientific literature reviews from 2019, 2023, and 2024, bovine colostrum could be specifically useful in the following areas of health and wellness:12 13 46

• Balancing the gut microbiome
• Protection against drug-induced injuries (e.g., anti-inflammatories)
• Protection against traveler's diarrhea and other gastrointestinal infections
• Fortification against intestinal inflammation
• Fighting infections
• Therapies for cardiovascular diseases, autoimmune diseases, and diarrhea
• Performance and immune function recovery after high-intensity exercise
• Reducing skin inflammation
• Stimulating skin repair

One 2014 study found that colostrum supplementation in older adults (median age around 59) resulted in improved cognitive function over eight weeks, although it’s worth noting that participants received 60g of colostrum per day, much higher than a label-recommended dose of ARMRA (60g of colostrum would be half a jar of Health Revival).14

An earlier study, performed on rats induced with intracerebral hemorrhage, showed that subjects receiving daily intragastric injections of just 0.4g/kg of colostrum had smaller brain hemorrhage lesions and less short-term memory impairment.15 The human equivalent dose would be 0.06g/kg, but we can’t say for certain how an intragastric injection would measure up with a single serving of ARMRA. More research studies in the future will be useful in closing this gap in knowledge, but if we (for the time being) consider powdered colostrum to be as potent as an injection, then you’re looking at 9-12g of powder for a human weighing 150-200lbs.

Key bioactive compounds in ARMRA

Among bovine colostrum’s hundreds of potentially helpful compounds, the bioactive ingredients most associated with health improvements are:4

Additional ingredients in ARMRA Performance Revival

ARMRA's Performance Revival is a formula tailored to the physically active. While providing the same amount of bovine colostrum concentrate as Health Revival, it features three additional ingredients alleged to enhance performance and post-exercise recovery:

So, it looks like Performance Revival is broadly underdosed. Even the colostrum quantity is low. Not until the 3.2g threshold have studies on athletes seen positive effects on factors like recovery.50 If you combine Performance Revival with Health Revival, you get just 2g of colostrum in total, so you’d have to increase your serving count to benefit from it.

Colostrum powders should be generally safe to use for most adults. Adverse effects are the most likely to arise among people with dairy intolerances. If you can't properly digest lactose, a high enough dose of ARMRA may cause temporary gut pain, gas, bloating, diarrhea, or nausea.28 If you have a milk or whey allergy, you should avoid colostrum supplements altogether, as even a small amount can cause anaphylaxis.7 ARMRA claims to remove the casein in its colostrum, so it might be safe for those with a casein allergy, but we strongly recommend discussing it with your doctor first.

Other reactions that may affect the general population include skin rash and gastrointestinal upset, but these aren't terribly common.

Similar principles apply to the other ingredients found in ARMRA's flavored varieties, including Performance Revival:

• Blood Orange: citric acid, annatto extract, and stevia
• Vine Watermelon: malic acid, dragon fruit, and stevia
• Peach Persimmon: malic acid, natural peach persimmon flavor, stevia, beet root (for color), and turmeric root (for color)
• Performance Revival: cacao, black cumin, tart cherry, stevia

Citric and malic acid are both Generally Recognized as Safe (GRAS) by the FDA,29 30 and numerous studies attest to stevia's safety for human consumption.31 As for the other ingredients, there's little to no evidence to suggest broad danger, but allergies and other intolerances aren't uncommon. If you aren't sure about your ability to tolerate any of these additives, we recommend speaking with your doctor for their professional input.

Bovine colostrum for children and pregnant/breastfeeding women

Bovine colostrum appears to be safe for use among children, according to a 2021 review of its potential benefits in pediatric nutrition and health.32 The authors of a more recent 2024 review would broadly agree,49 as would Dr. Lauren Crosby, a pediatrician and Fellow of the American Academy of Pediatrics, who notes that children as young as one year old can take bovine colostrum and realize health benefits.33 That being said, we still suggest speaking with your family’s pediatrician beforehand, just to make sure colostrum won’t negatively impact any aspect of your child’s health.

When it comes to colostrum for pregnant or breastfeeding women, the jury’s still out. We touched on this in an earlier section, citing a lack of evidence to recommend use among this population. Indeed, Drugs.com, a source of drug information certified for content assurance and reliability by AACI Healthcare's TRUST program, advises pregnant and breastfeeding women to avoid bovine colostrum supplements at this time.34 35

ARMRA’s prices are unchanged since we last checked in, and customers still have the choice between one-time purchases and autoship subscriptions. There is, however, a new jar size for the Unflavored variant of Health Revival. Here’s a quick breakdown of all the pricing:

A few insights you can draw from this table:

• Unflavored jars are the most cost-effective option — especially that new XL jar, which should last you nearly a year of daily consumption — but they represent high barriers to entry.
• The stick packs (i.e., Travel Sticks) are the inverse: lower barrier to entry but less cost-effective.
• Flavored variants cost a premium, but their prices are roughly comparable to those of competitors. For Example, a bulk jar of WonderCow (flavored or unflavored) costs up to $1.08 per serving, and Miracle Moo is as much as $1.33 per serving.
• A subscription nets you only a 5% discount per purchase, which is low (WonderCow takes 15% off for subscriptions).

ARMRA cost breakdown for multi-serving users

ARMRA states that users can see “added benefits” by taking multiple servings per day. Multi-serving users will, of course, deplete their ARMRA more quickly and need to re-up their supply more frequently. So, here’s a chart breaking down the amounts and costs of ARMRA for people consuming 2-4 daily servings of the Unflavored variant in regular-size jars (based on subscription prices):

ARMRA bundles

Aside from its individual colostrum products, ARMRA offers several bundles of various product combinations at discount rates:

• The Peach Principle: one Peach Persimmon bulk jar plus a peach-colored carafe ($145.33, or $138.06 as a subscription)
• The Revival: one Unflavored Health Revival bulk jar plus one box of Unflavored Travel Sticks ($142.48, or $135.36 as a subscription)
• The Transformer: one Unflavored Health Revival bulk jar plus one Performance Revival bulk jar ($180.48, or $171.46 as a subscription)
• The Catalyst: one Unflavored Health Revival bulk jar plus one box of Blood Orange Travel Sticks ($151.98, or $144.38 as a subscription)
• The Revitalizer: one Unflavored Health Revival bulk jar plus one ARMRA Whirl frother ($128.23)

ARMRA shipping and payment

The standard shipping option adds a flat rate of $4.99 to your order unless you subscribe or cross the $120 free-shipping threshold. Two things about this threshold we dislike:

• It used to be $80.
• The XL jar is the only single-item order that will cross it.

Yes, even a one-time purchase of a flavored jar variant, which is just $0.01 under the threshold, would add an extra $4.99 to your bill, at minimum.

On the bright side, you can offset the impact of ARMRA on your income by paying via HSA/FSA. The fact that ARMRA accepts this payment option is a major differentiator relative to its competitors.

ARMRA's return and refund policy

ARMRA's return policy has some caveats. All Stick Packs are refundable, even if you've opened the box (although you can’t return individual sticks that you’ve opened). For bulk jars, however, only unopened items are eligible for returns. That's because ARMRA colostrum is a food product, and accepting an opened container would violate the company’s health code. The one exception would be in the case of an order that arrives opened because of damage. In that situation, you should immediately reach out to ARMRA so customer service can evaluate your case.

To initiate a domestic return, you’ll need to email the company to request a return shipping label within 30 days of receiving your order. Along with the label, ARMRA will provide instructions on where and how to return the package. You should then receive a refund within ten to 15 days from the time the return package arrives at ARMRA's warehouse, minus a $6 fee for processing your return. International returns follow the same procedure, but the customer bears the responsibility for return shipping costs. If you want to return your product, it’s critical that you follow this protocol. Otherwise, ARMRA will designate your case as an "unauthorized return" and deny you a refund.

Canceling your ARMRA autoship subscription

Canceling your ARMRA autoship subscription is a simple process that you can manage entirely online.

To begin, log in to your account and scroll to the bottom of the dashboard to locate the "Cancel Subscription" button. When you click the button, a pop-up will ask for your reason for cancellation. Choose whichever one best describes your circumstances.

If you select "Product is too expensive," ARMRA will encourage you to retain your subscription with a $5 coupon toward your next autoship delivery. If you deny the coupon, ARMRA will then recommend that you pause your order instead (a proposition that arises with other cancellation options, too). If you deny that, your cancellation will go through, and ARMRA will send you an email to confirm.

Bear in mind that you can only cancel future deliveries. ARMRA won't cancel or modify your order if your next delivery has already been processed.

Non-supplement products by ARMRA

ARMRA's product line also includes several merchandise items, including a couple of new ones for 2025:

• 350ml borosilicate carafes: $32.99
• Electric frother: $24.99
• Tote bag: $28.99
• Travel pouch (new): $24.99
• Pup Revival dog toy (new): $27.99
• Sweatshirt: $65.99
• T-shirt: $45.99

The first two items have some utility, certainly. The carafes are good for shaking up your colostrum drink and sipping on the go, and the frothers (an item offered by Miracle Moo and WonderCow, too) can quickly whip your colostrum powder into your chosen liquid. As for the others, their value is yours to determine. We think, at least, that the tote bag is handsome enough, and the dog toy (a squeaky plush jar of ARMRA) is cute.

A wide range of flavors is one of ARMRA's distinguishing characteristics. Whereas competitor Miracle Moo offers just two flavor varieties (unflavored and chocolate), ARMRA's product line includes five. The current lineup, as of this writing, includes:

• Unflavored (Health Revival)
• Blood Orange (Health Revival)
• Vine Watermelon (Health Revival)
• Peach Persimmon (Health Revival)
• Chocolate (Performance Revival)

The Unflavored Health Revival tastes similar to just about any standard colostrum powder. Stirred into water, it's mildly savory with a character reminiscent of buttermilk. The flavor isn't unpleasant and may even do double-duty as a palatability enhancer for your next breakfast (one might imagine it stirred into a bowl of cooled oats, for example). In comparison, WonderCow’s unflavored offering has a slightly sweeter profile — not sugary, but “sweet” in the way milk is sweet — which mixes better with foods and beverages that already have dairy in them.

Blood Orange reminded our testers of sugar-free orange Jell-O, a quality made possible by ARMRA’s addition of natural blood orange flavor, stevia leaf extract, and citric acid. It's tart but not sour, and we agreed that a glassful of Blood Orange ARMRA water is quite enjoyable.

Vine Watermelon is downright tasty and one of our favorites of the line. It gave us the taste impression of watered-down watermelon candy. It, too, includes natural flavoring and stevia leaf extract but also malic acid, the likely source of the flavor's subtle and appealing sourness.

Peach Persimmon is another favorite. In water, it’s a refreshing fruit drink; in milk, a kind of exotic dairy beverage. Its flavor reminded one of our testers of Japanese sugar candy.

Compared to the Health Revival flavor options, the Chocolate-only Performance Revival wasn't as well-received. In truth, it's our testers' least favorite. Bitterness from the cacao is to be expected, but it also has a very strong stevia flavor, which itself may contribute to this flavor’s astringency. Performance Revival is unlikely to be a pleasure drink unless you're a fan of bittersweet flavor profiles.

You can mix ARMRA colostrum powder into just about any cold, cool, or lukewarm liquid or food (again, hot temperatures can diminish its efficacy). For our testing, we opted to use cold water, which helped give us a sort of baseline for how well the product dissolves (not to mention how it tastes).

Most of the powders from both the bulk jar and the Travel Sticks mixed fairly well in cold water. You’ll probably be left with a few small powder clumps, though nothing so horrible as to be unpalatable. If you use a capped water bottle, cocktail shaker, or one of ARMRA's branded carafes, you can vigorously shake the mixture to better homogenize your drink.

Amazon reviews concerning solubility are mostly in line with our experience, with less than half of all pertinent comments complaining of much difficulty. In that regard, ARMRA performs similarly to Miracle Moo and WonderCow.

Customer support

For us, customer support at ARMRA was swift and seamless. The website includes a collapsible chat widget on every page through which you can seek the answers you need. The initial response will be an automated link to a page in the knowledge hub, but if the answer isn't satisfactory, you can choose to connect with a live representative.

Most recently, we used the chat widget to ask whether a $119.99 order would qualify for free shipping. Our representative, understanding that $119.99 is just $0.01 removed from the $120 free-shipping threshold, asked us to hold on a minute while they asked around. In about five minutes, they were back with an answer. The answer was disappointing (it was no, though not in so many words), but the turnaround time wasn’t.

In comparison, we also interacted with service representatives at WonderCow and Miracle Moo, neither of which has a chat widget on their websites. WonderCow’s team responded to our question within half a business day, but Miracle Moo took five days to respond to our initial question and two more to answer it. We had to ask several of Miracle Moo, as well, because the team’s responses were less direct, such that we were left wondering whether they truly satisfied our inquiries.

While the bovine colostrum supplement market isn't vast, ARMRA does contend with a few direct colostrum-focused competitors and several supplement providers that include colostrum among their product offerings. All the brands described below sell colostrum as a powder supplement for gut health, aesthetic health, immunity, performance recovery, or overall wellness.

Miracle Moo

Miracle Moo's key distinguishing characteristic is the addition of ImmunoLin, another protein-based, Ig-rich supplement derived from cows. But even with ImmunoLin, Miracle Moo has an IgG concentration of only 30%, which is lower than either ARMRA or WonderCow. Also, through email correspondence, we discovered that Miracle Moo does contain casein, making it unsuitable for those with dairy allergies.

Since we first looked at Miracle Moo, it has added a few products to its catalog. Here’s what it looks like in 2025:

• Colostrum powder (bulk jars): 1,500mg of bovine colostrum and 300g of ImmunoLin per serving; available in 30-day supplies (unflavored or chocolate) and 60-day supplies (unflavored only)
• Colostrum powder (travel size): the same as above, with the same price, but in portable stick packs (unflavored 30-day supply only)
• Colostrum capsules: the same composition as the powder; 30 servings to a bottle
• Colostrum chews: 500mg of bovine colostrum; 60 servings to a bag

Miracle Moo is definitely the budget option among colostrum-centric brands. The base prices are among the lowest we’ve found for any colostrum supplement; a subscription unlocks a discount, further savings are had by buying in bulk, and all orders are eligible for free two-day shipping. However, the discount rates have decreased since 2024, and not all products are available as subscriptions. This table lays it all out:

The discount rate is approximately 15% for your first subscription order. Subsequent orders, however, are only 10% off (e.g., $35.95 for a one-pack 30-day powder from your second subscription delivery onward). Also, you should know that information about the variable discount rate is not easy to find on the Miracle Moo website. We had to reach out to Miracle Moo’s customer support team to verify the lower rate, and it wasn’t until after a week and three rounds of emails that we finally got a straight answer to our very simple question.

WonderCow

WonderCow states its colostrum has an IgG concentration of 40%, but there's some ambiguity as to how that compares with ARMRA. One direct source claims ARMRA has an IgG concentration greater than 40%, which means it could have a better potential efficacy than WonderCow. But another direct source says the concentration is "no less than 35%." In either case, both ARMRA and WonderCow outperform Miracle Moo on the IgG front.

WonderCow also has a couple of qualities in common with ARMRA. First, sustainability plays an integral part in its business philosophy, as its colostrum is sourced from humanely treated cows on U.S. farms that follow a calf-first initiative. Second, WonderCow sells colostrum supplements in both bulk jars and travel-friendly single-serving packets. The flavor lineup has expanded since 2024. Bulk jars are available in unflavored, vanilla, chocolate, elderberry, and matcha variants. The stick packs come in either unflavored, vanilla, or elderberry.

In addition to straight colostrum concentrate, the WonderCow line features several products that ARMRA doesn't have:

• WonderCream, a colostrum powdered creamer
• Colostrum capsules
• WonderGlow, a colostrum capsule supplement with collagen, hyaluronic, and lactoferrin (for skin, hair, and nails)
• Bioactive collagen powder
• Bioactive beef protein powder
• Beef liver capsules

Among these, only WonderCream is remarkable. It’s fortified with 4,000mg of coconut medium-chain triglycerides (MCTs) and 500mg of lion's mane mushroom. Apart from adding a mild coconut flavor, the coconut MCTs may help with body weight, energy, and cognitive health,36 and the lion's mane might promote better cognitive function, heart health, and gut health.37

You can purchase any of WonderCow's supplements as either a one-time purchase or a subscription, and standard domestic shipping is free. Some products are available in multiple sizes. Here’s a table of every WonderCow colostrum product with the price breakdown, as well as the variable serving counts, per-serving costs, flavors, and delivery intervals (prices are rounded to the nearest cent):

General supplement providers

Each of the companies discussed in this section has a broad product line that includes colostrum. They're not the only general supplement providers to offer colostrum, but they stand out for being generally well-regarded online.

Among these providers, Adapt Naturals is the most transparent about its colostrum product, Bio-Avail Colostrum+, which has an IgG concentration of 40%. Similar to ARMRA, Adapt Naturals sources its colostrum from grass-fed cows on U.S. farms, follows a calf-first initiative, and uses a cold-process pasteurization method to retain immunoglobulin integrity. But unlike ARMRA, Bio-Avail Colostrum+ does contain casein and isn't suitable for people with dairy allergies.

Brain Bean doesn't outright divulge details about its IgG concentration or casein content, but it’s notable for offering two colostrum products. One is the Ultra Pure Colostrum, and the other is the Brain-Immune Gut-Brain Formula for supporting the gut-brain connection — this is a bidirectional communication pathway that may influence factors like satiety, cravings, gut muscle movements, mood, stress, and behavior.38

Codeage has even more: five colostrum products for humans (plus another one for pets) at unspecified IgG concentrations. Our favorite of these is Immuno Colostrum, a high-dosage (3g) oral supplement that won our pick for capsule alternative in our guide to the Best Colostrum Supplement.

Two other companies — Elm & Rye and Mt. Capra — also provide no information about IgG concentration or casein content. But the latter is worth examining further because its colostrum powder derives from goats instead of cows. A 2022 review in Beverages explains that goat colostrum contains more lactose than its bovine counterpart, so Mt. Capra probably isn't ideal for people with lactose intolerance. It may, however, provide additional health benefits, particularly with regard to lowering blood pressure.39
