Innerbody Labs Astaxanthin+ Review

Every day, your body is exposed to things that create oxidative stress, from sunlight and air pollution to exercise and simply getting older.1 Your body is well equipped to handle much of that damage on its own, but over time, those defenses become less efficient. That's one reason oxidative stress has been linked to changes in skin, vision, brain health, and other aspects of aging.2

If you're considering an antioxidant supplement, astaxanthin is one of the best-supported options currently available.3 Human studies have associated it with improvements in skin appearance, visual function, exercise recovery, and even certain measures of cognitive performance. However, most astaxanthin supplements have one thing in common: they stop at astaxanthin alone.

One product taking a broader approach is Astaxanthin+ from Innerbody Labs. It pairs clinically studied doses of astaxanthin with lutein and zeaxanthin — two carotenoids that complement astaxanthin by concentrating in the eyes and brain and supporting many of the same healthy aging pathways.4 In this review, we'll examine the science behind the formula, compare it with competing products, and help you decide whether it's worth your money.

Our take is simple: Astaxanthin+ is one of the most thoughtfully formulated carotenoid supplements we reviewed. It combines doses of three well-studied antioxidants that align with human research and backs that formulation with third-party testing and publicly available certificates of analysis. While it costs more than many standalone astaxanthin supplements, we think the broader formula helps justify the premium. Below, we'll explain where it excels, where it may fall short, and who is most likely to benefit.

At Innerbody Research, we carefully evaluate every product and service we review, including the growing number of antioxidant and carotenoid supplements on the market. We've spent hundreds of hours researching astaxanthin and related carotenoids, analyzing clinical studies, comparing supplement formulations, and testing many of the leading products ourselves.

Throughout that process, we found ourselves coming to the same conclusion again and again: many astaxanthin supplements either stopped at astaxanthin or added a handful of extra ingredients without much thought behind the formula. We believed there was an opportunity to create a more complete antioxidant supplement — one built around the available evidence instead of simply adding more ingredients. That led to the development of Innerbody Labs Astaxanthin+.

Because Innerbody Labs is the product arm of Innerbody Research, reviewing one of its own products presents an obvious conflict of interest. We believe the best way to address that is through transparency. Throughout this review, we'll explain the reasoning behind the formula, point out where competing products may be a better fit, and discuss the limitations of Astaxanthin+ alongside its strengths.

Like all health-related content on our site, this review was vetted for accuracy by members of our Medical Review Board and will continue to be updated as new research becomes available.

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions about their health and wellness.

To honestly evaluate Innerbody Labs Astaxanthin+, we compared it with many of the leading astaxanthin and antioxidant supplements on the market, using the same criteria we apply to every supplement we review. We focused on four areas that matter most to consumers: effectiveness, safety, cost, and convenience.

Here's how Astaxanthin+ performed in each category.

Effectiveness

Antioxidants can be frustrating to shop for. Almost every product promises to fight oxidative stress or support healthy aging, making it difficult to separate ingredients backed by meaningful human research from those built around marketing claims.

Astaxanthin is one of the exceptions. Over the past two decades, it has been studied in hundreds of human and laboratory studies, with clinical trials exploring its effects on skin health, visual function, exercise recovery, cognitive performance, and oxidative stress.2 5 6 7 8 9 Just as importantly, many of those trials measured meaningful health outcomes — not simply antioxidant levels in a test tube.

Of course, strong research on an ingredient doesn't automatically make for a great supplement. The quality of the source, the dose, and even how the ingredient is delivered all play an important role in whether a formula reflects the science. Here's what stood out to us about Astaxanthin+:

• A clinically studied dose. Astaxanthin supplements range from about 4mg to 24mg, but more isn't always better. 12mg has consistently appeared in successful human trials, making it one of the best-supported doses in the scientific literature.2 11 13
• A high-quality source. Innerbody Labs sources its astaxanthin from AstaPure®, a natural astaxanthin derived from Haematococcus pluvialis and extracted using supercritical CO₂ rather than chemical solvents. We also like that AstaPure® cultivates its microalgae under natural sunlight, allowing the algae to develop under conditions that more closely resemble their natural environment.
• An absorption-friendly delivery system. Because astaxanthin is a fat-soluble carotenoid, Astaxanthin+ suspends it in MCT oil instead of a dry capsule to help support absorption.14 15 38

The formulation goes beyond astaxanthin, too. It also includes 10 mg lutein and 2 mg zeaxanthin — two carotenoids with decades of eye health research behind them.16 The landmark AREDS2 trial helped establish these amounts as the most thoughtfully supported regimen for eye health, and they've since been used in numerous clinical trials evaluating lutein and zeaxanthin.17 18

There’s also some evidence supporting the combination. In one randomized trial, astaxanthin, lutein, and zeaxanthin helped mitigate declines in eye–hand coordination after prolonged screen use, though we’d still like to see more long-term research on the specific formula.19

If you're looking for an astaxanthin supplement, this formula checks the boxes we care about most: an astaxanthin dose used successfully in human trials, complementary carotenoids at research-backed amounts, and a delivery method designed to maximize absorption. That's exactly what we'd hope to see in a top-tier formula.

Safety

The ingredients in Astaxanthin+ have excellent safety records. Human clinical trials and safety reviews have consistently found astaxanthin, lutein, and zeaxanthin to be well tolerated at the doses commonly found in supplements, with few reported side effects. Astaxanthin has been studied safely at doses up to 24mg per day — twice the amount provided here — while the formula's 10mg lutein and 2mg zeaxanthin match the amounts used in the landmark AREDS2 trial and numerous subsequent clinical studies.16 20

That means the bigger safety question isn't whether these ingredients are safe — it's whether the supplement actually contains what the label claims and is free from contaminants. Because dietary supplements aren't regulated as rigorously as prescription medications before reaching the market, we place a high value on companies that invest in independent quality testing and make those results available to consumers.

Innerbody Labs manufactures Astaxanthin+ in a GMP-compliant facility and subjects every batch to independent third-party testing for identity, potency, purity, and contaminants. Better yet, the company publishes Certificates of Analysis (COAs) directly on each product page, allowing customers to verify those results before purchasing. While several brands that sell astaxanthin supplements, including Life Extension, perform third-party testing, relatively few make that level of testing transparency so easy to access.

Taken together, the formula's doses that align closely with the human research, an excellent ingredient safety profile, and transparent quality-control practices give us confidence recommending Astaxanthin+ to most healthy adults seeking an astaxanthin supplement.

Cost

Astaxanthin+ occupies an interesting place in the market. At $28 for a one-time purchase, it's priced similarly to many standalone astaxanthin supplements. The difference is that it doesn't stop at astaxanthin. Each softgel also includes 10mg lutein and 2mg zeaxanthin, making it more comparable to a complete carotenoid formula than a single-ingredient supplement.

For that reason, we think it's more helpful to compare Astaxanthin+ against other products containing astaxanthin, lutein, and zeaxanthin together, or against the cost of purchasing those ingredients separately.

Note: Life Extension provides 4mg of zeaxanthin and meso-zeaxanthin combined, but because they're included in a proprietary blend, the exact amount of each isn't disclosed.

If your goal is simply to minimize cost, buying two separate supplements remains the least expensive approach. Pairing Double Wood's 12mg astaxanthin with Nutricost's lutein and zeaxanthin costs about $0.57 per serving, roughly $0.36 less than Astaxanthin+. Over a month, that's a difference of about $11.

Life Extension's MacuGuard is another compelling alternative. Like Astaxanthin+, it combines astaxanthin, lutein, and zeaxanthin into a single softgel while costing less per serving. It also includes saffron, an ingredient with promising evidence for supporting eye health. However, MacuGuard contains 6mg of astaxanthin — half the amount found in Astaxanthin+ — making the two formulas somewhat different products despite their similar ingredient profiles.

Ultimately, we think Astaxanthin+ earns its price. It combines a clinically studied 12mg dose of astaxanthin with amounts of lutein and zeaxanthin that match the landmark AREDS2 regimen in a single softgel. Innerbody Labs also uses AstaPure® astaxanthin derived from Haematococcus pluvialis and extracted using a supercritical CO₂ process rather than conventional solvents. Finally, the company publishes batch-specific certificates of analysis for every lot, giving customers an uncommon level of transparency. Together, those manufacturing practices, third-party testing, and the convenience of an all-in-one formula make Astaxanthin+ a strong overall value.

Subscribers can make that value proposition even stronger. The maximum subscription discount lowers the price from $28 to $21 per bottle (about $0.70 per serving), narrowing the cost difference between Astaxanthin+ and buying separate astaxanthin and lutein/zeaxanthin supplements while still providing the convenience of a single daily softgel.

Convenience

When we evaluate convenience, we look beyond the daily regimen to the overall customer experience, including product transparency, ordering, shipping, and customer support.

Astaxanthin+ scores highly because it simplifies what could otherwise be a two-supplement routine. Instead of purchasing separate astaxanthin and lutein/zeaxanthin products, you get all three carotenoids in a single daily softgel. The regimen is easy to remember, requires no cycling or dose adjustments, and each bottle provides a straightforward 30-day supply.

Innerbody Labs also stands out for transparency. The product page explains why each ingredient was selected, cites the research behind the formula, and publishes batch-specific certificates of analysis so customers can verify third-party testing results before purchasing — a level of detail relatively few supplement companies provide.

Ordering is straightforward, with one-time purchases and subscription options available. Orders over $50 ship free, while smaller orders incur a $6.99 shipping fee. Astaxanthin+ is backed by a 30-day money-back guarantee and customer support via email.

Life Extension does offer a substantially longer 365-day satisfaction guarantee, and some competitors provide live chat support. Still, thanks to its simple one-softgel regimen, excellent transparency, and straightforward purchasing experience, Astaxanthin+ ranks among the more convenient astaxanthin supplements we've reviewed.

Innerbody Labs Astaxanthin+ is a daily supplement that combines three well-studied carotenoids — astaxanthin, lutein, and zeaxanthin — in a single softgel. Carotenoids are naturally occurring pigments produced by plants, algae, and certain microorganisms that give many fruits, vegetables, and marine organisms their yellow, orange, and red colors. Several carotenoids, including the three in Astaxanthin+, also act as antioxidants in the body, helping protect cells from oxidative damage.

Here's a quick look at what's inside:

• Astaxanthin: 12mg
• Lutein: 10mg
• Zeaxanthin: 2mg

The formula features AstaPure® astaxanthin, a branded ingredient derived from Haematococcus pluvialis microalgae — the natural source featured in much of the clinical research on astaxanthin. Unlike conventional extraction, which can rely on potentially hazardous organic solvents that introduce contaminants and reduce the efficacy and bioavailability of natural compounds, AstaPure® uses cleaner, solvent-free supercritical CO₂ extraction.14 Research suggests this method may also enhance astaxanthin's effects.15

The lutein and zeaxanthin are supplied by a standardized 50mg marigold (Tagetes erecta) flower extract, one of the richest natural sources of these carotenoids. The formula also suspends its carotenoids in MCT oil to support absorption, since all three are fat-soluble compounds.

Although astaxanthin, lutein, and zeaxanthin all belong to the carotenoid family, they don't all behave the same way in the body. After absorption, each accumulates in different tissues and has been studied for different health benefits. That's one reason Innerbody Labs combined all three into a single formula.

Here's a closer look at what the research says about each ingredient.

Astaxanthin

Astaxanthin is a naturally occurring carotenoid antioxidant produced primarily by the microalgae Haematococcus pluvialis. It's the same pigment that gives salmon, shrimp, lobster, and flamingos their distinctive pink-red color after they consume astaxanthin-producing organisms. In supplements, it's valued because laboratory and human studies suggest it's one of the more biologically active carotenoids.

Once absorbed, astaxanthin can incorporate into cellular and mitochondrial membranes. Its structure allows it to span the lipid bilayer, helping shield the membrane from free-radical damage on both sides. Researchers think this unique structure is one reason astaxanthin has attracted so much scientific attention.

Based on the available research, astaxanthin may:

Lutein and zeaxanthin

Lutein and zeaxanthin are naturally occurring carotenoids found in leafy greens, corn, egg yolks, and other colorful fruits and vegetables. Unlike astaxanthin, which circulates throughout the body and has been studied for a wide range of health outcomes, these two carotenoids accumulate primarily in the retina, where they play specialized roles in supporting visual health.

After absorption, they concentrate in the macula — the central part of the retina responsible for sharp, detailed vision. There, they act as antioxidants while also filtering some high-energy blue light before it reaches sensitive retinal tissue. Together, these two functions are thought to help protect the eye from the cumulative effects of oxidative stress.

Taken together, the research paints a clear picture. Astaxanthin, lutein, and zeaxanthin each have distinct strengths, but there's also meaningful overlap in the conditions researchers study them for. Eye health is the clearest example, with multiple clinical trials evaluating astaxanthin alongside lutein and zeaxanthin rather than on its own. By combining clinically studied amounts of all three carotenoids, Innerbody Labs has created a formula that closely reflects much of the current research.

Astaxanthin+ is a supplement that most healthy adults could potentially benefit from. Oxidative stress is a normal part of aging and everyday life, and carotenoid antioxidants help the body defend against it. Researchers have studied astaxanthin, lutein, and zeaxanthin across a wide range of health areas, making this a good option for anyone looking to support long-term wellness rather than address a single deficiency or symptom.

People interested in healthy skin may find Astaxanthin+ especially appealing. Human studies have linked astaxanthin supplementation to improvements in skin hydration, elasticity, and the appearance of fine lines and wrinkles, while lutein and zeaxanthin have also shown promise for supporting skin moisture and protecting against UV-induced oxidative stress. Although more research is still needed, the evidence suggests these carotenoids may help support healthier-looking skin from within.

The strongest evidence for this combination, however, centers on eye health. Astaxanthin, lutein, and zeaxanthin have all been studied for supporting visual function, with several clinical trials evaluating them together. Whether you're beginning to notice age-related changes in your vision or simply spend long hours looking at computers, tablets, and smartphones, Astaxanthin+ provides clinically studied amounts of these carotenoids in a single daily supplement.

Who might want to look elsewhere?

While Astaxanthin+ has one of the more comprehensive carotenoid formulas we've reviewed, it isn't the right choice for every situation. If your eye doctor has recommended an AREDS2 supplement for age-related macular degeneration (AMD), you'll likely want a product that contains the complete AREDS2 formulation. Astaxanthin+ provides the same 10mg lutein and 2mg zeaxanthin used in the landmark study, but it isn't intended to replace the additional vitamin C, vitamin E, zinc, and copper that were also part of the research. Because the protective effects seen in AREDS2 were based on the complete formula, we can't assume that lutein and zeaxanthin alone would provide the same benefits for people with AMD.

Astaxanthin+ also isn't a good fit if you're expecting sharper eyesight. Astaxanthin, lutein, and zeaxanthin may support retinal health and certain aspects of visual performance, but they aren't likely to make your eyesight sharper or eliminate the need for glasses or contacts. Most clinical studies report improvements in measures like contrast sensitivity, glare recovery, and visual comfort — not sharper visual acuity.

Based on the available research, Astaxanthin+ should be safe for the vast majority of healthy adults. Astaxanthin, lutein, and zeaxanthin all have well-established safety profiles in human clinical trials, and the doses used in this formula fall comfortably within ranges that have been studied without serious safety concerns. Like any dietary supplement, however, there are a few considerations worth keeping in mind.

Beyond the ingredients themselves, Innerbody Labs also takes several steps to help ensure the finished product is safe and accurately labeled. Astaxanthin+ is manufactured in GMP-certified facilities, every batch undergoes independent third-party testing, and the company publishes batch-specific certificates of analysis (COAs) on its website. These reports allow customers to verify potency while confirming the product has been screened for contaminants such as heavy metals, microbes, and other impurities — a level of transparency that remains relatively uncommon in the supplement industry.

Overall, we found very little to be concerned about from a safety standpoint. Between the clinically studied ingredients, conservative dosing, and publicly available third-party testing, Astaxanthin+ checks nearly every box we look for in a high-quality supplement. As with any dietary supplement, we still recommend speaking with your healthcare provider before taking it, particularly if you're pregnant, breastfeeding, taking prescription medications, or managing a chronic medical condition.

Innerbody Labs offers Astaxanthin+ as either a one-time purchase or a subscription, with larger discounts for customers who choose longer subscription intervals. Here’s how the pricing breaks down:

If you plan to take Astaxanthin+ long term, the three- and six-month subscriptions offer the best savings. The six-month option brings the cost down to $21 per bottle, or $0.70 per serving, while both multi-bottle subscriptions qualify for free shipping because they exceed Innerbody Labs’ $50 threshold.

If you'd rather start with a smaller commitment, the monthly subscription still saves 15% compared to a one-time purchase. The drawback is shipping: both one-time purchases and monthly subscriptions fall below the $50 minimum and incur a $6.99 shipping fee. That makes the one-time purchase $34.99 delivered, or about $1.17 per serving, unless you add another product to your order to qualify for free shipping.

Astaxanthin+ also comes with a 30-day money-back guarantee, and Innerbody Labs accepts returns even if you've opened and partially used the bottle. That gives you some time to try the product, make sure you tolerate it well, and see how easily it fits into your routine. A 30-day guarantee is pretty standard in the supplement space, although some competitors give you longer. Doctor's Best, for example, offers 60 days.

Astaxanthin+ stands out for combining a full 12mg dose of astaxanthin with clinically studied amounts of lutein and zeaxanthin. But not everyone needs all three carotenoids, and depending on your goals, a simpler or more specialized option may make more sense.

Diet

Supplements aren't the only way to get these carotenoids. Astaxanthin occurs naturally in salmon, trout, shrimp, krill, and other pink or red seafood, while lutein and zeaxanthin are abundant in foods such as spinach, kale, collard greens, egg yolks, corn, peas, pistachios, and orange and yellow peppers.36 37

A varied diet also gives you nutrients Astaxanthin+ doesn't provide, including omega-3 fatty acids, vitamins, minerals, polyphenols, and other carotenoids. And because carotenoids are fat-soluble, eating these foods with healthy fats — such as olive oil, avocado, nuts, or fatty fish — can improve their absorption.

For people who regularly eat plenty of these foods, supplementation may be less important. But getting consistent, research-backed amounts of all three carotenoids from food alone can be difficult. That's ultimately where Astaxanthin+ makes its strongest case: one daily softgel provides clinically studied amounts of astaxanthin, lutein, and zeaxanthin without requiring you to piece together multiple supplements.
