Viasil Reviews

Nearly 1 in 5 men experiences erectile dysfunction at some point. It can feel embarrassing in the heat of the moment, but there’s nothing to be ashamed of. And if you’re a man over 70 or take SSRIs for depression, the odds are even higher that you’ll develop symptoms like low libido or difficulty maintaining an erection.

The good news is that there’s plenty of help out there. The better news is that lots of those potential remedies — like Viasil — don’t even require a prescription.

In this review, we’ll do a deep dive into this natural supplement by Swiss Research Labs. You’ll learn what’s in it, how it all works, and whether or not Viasil can bring a little heat back to your bedroom.

Why you should trust us

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.

We extensively test each health service or product we review, including Viasil. We try our best to give you, our readers, an unbiased exploration of at-home health options, free of marketing jargon or gimmicks. We evaluate products and services based on their adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren’t part of our job, and would we recommend it to family and friends?

Additionally, 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.

How Viasil works

Viasil is a men’s performance-enhancing supplement taken in tablet form. It works by promoting better blood flow, increasing nitric oxide production (the main compound responsible for erections), and combating low libido caused by aging or SSRIs. Rather than treating the condition with a drug like Viagra, Cialis, or one of the generics on the market, Viasil lets you use natural ingredients.

Your order comes with Viasil tablets by default and may include a free Viasil Instant Erection Gel bottle depending on how much you buy. Let’s take a look at each in more detail.

Viasil tablets

Viasil tablets are once-per-day pills designed to optimize your body’s natural nitric oxide production and blood flow, encouraging sexual health in men. To see how each ingredient works to achieve this goal, let’s look at them all below. And remember to speak with your doctor whenever you’re adding a new supplement to your regime.

Actiful (700 mg)

Actiful is the main component of Viasil’s capsules. It’s the name given to a supplement created in 2019 that combines citrus sinensis (extracted from oranges) and punica granatum complex (extracted from pomegranates). It was originally created to supplement energy, mental well-being, and improved blood flow in people 55 and older. The only existing clinical study, funded by the company that created Actiful, found a significant increase in endurance and strength.

A clinical study on the effects of pomegranate juice showed a modest result in improving erections. Twenty-five of 42 men reported an improvement, which is statistically insignificant but indicates some potential.

And a citrus sinensis animal study gave rats a 50 mg/kg extract of orange peels to reduce ED symptoms induced by SSRIs (Paxil in this case). There was a significant decrease in sexual behavior, but some improvement in ED symptoms among the Paxil-treated rats.

Zinc (1.5 mg)

Zinc is an essential mineral that plays a part in many vital functions. It helps maintain cell health, plays a role in protein synthesis, and fuels 100 enzymatic functions — but your body can’t make it on its own. So getting a slight boost like this helps you avoid an unwanted deficiency. This clinical study also found a direct correlation between zinc and testosterone levels. Supplementation improved T counts significantly after six weeks.

Horny Goat Weed 10:1 Extract (100 mg)

Even though it’s a well-known supplement used for ED and low libido for decades now, very little dedicated clinical research exists about horny goat weed. According to this clinical review, the active ingredient, icariin, has successfully treated aged, diabetic, and castrated animals. But similar results have yet to be reported in humans. In animals, doses of up to 750 mg/kg of weight have been used without adverse side effects. But similar servings taken long-term have not been studied in humans. Try to avoid horny goat weed if you’re taking blood pressure meds. Horny goat weed naturally lowers blood pressure and can amplify some prescription drug effects.

Tribulus Terrestris 12:1 Extract (25 mg)

Tribulus terrestris is a plant that’s been used as a folk remedy for low libido. Improved sexual satisfaction is one benefit backed up by this clinical study. The study gave 90 men 750 mg per day over 12 weeks and found significant improvements in erections and satisfaction. But a conflicting study found no difference between a placebo group and a tribulus terrestris group over 30 days.

Panax Ginseng Extract (20 mg)

Panax ginseng (a.k.a. Korean or red ginseng) is a popular herbal supplement for its reported benefits in mental acuity and sexual performance. One comprehensive review showed improvements in seven studies among nearly 400 men according to several metrics vs. a placebo. Dosages ranged from 600-1,000 mg three times per day. The small dosage included in Viasil leaves some questions about whether or not it’s enough to be effective. And while red ginseng is safe for most people, it has a long list of potential interactions with prescription drugs.

Ginkgo Biloba 50:1 Extract (4.8 mg)

Ginkgo Biloba comes from one of the oldest living trees on earth with a history of use for preventing mental health conditions like Alzheimer’s and anxiety. One clinical study found that both men and women reported more satisfaction at every stage of sexual experiences (arousal, orgasm, afterglow). In this study, women found more success than men (91% vs. 76% respectively).

There are no clear guidelines on how much ginkgo Biloba you should take. But, keep in mind that the dosage in Viasil is minimal compared to other ginkgo supplements out there. A pure ginkgo supplement is anywhere from 100-500 mg per capsule. And most studies use doses of around 200-300 mg/per day.

Who could benefit from it and who probably won't

Based on the ingredients in Viasil, we believe older men would benefit the most. Actiful was designed with people over 60 in mind and is the bulk of the active ingredient contained in the tablets.

If you’re experiencing a lower libido due to SSRIs, Viasil might be worth a look. Several of its ingredients may address the adverse effects of antidepressants.

And remember that most of the studies cited utilized participants with sexual dysfunction. So if you’re someone with a healthy sexual function looking for a little boost, Viasil might not be much help for you.

Viasil Instant Erection Gel

Viasil’s instant erection gel isn’t available for direct purchase. Instead, it’s included free as part of a bundle with orders of two months or more. The company promises stronger erections in just 10-15 seconds when used in combination with Viasil tablets.

Unfortunately, a lack of clinical evidence and no data about efficacy or long-term safety make this a tough product to recommend.

Here’s a look at the gel’s ingredients:

  • L-Arginine - the main active ingredient, a naturally occurring amino acid that encourages healthy blood flow and increased nitric oxide production when taken orally
  • Water and Glycerine - the base of the gel
  • Polysorbate 20 - emulsifier safely used in beauty products to modify texture
  • Sodium Hydroxide - a pH-balancer used in soaps and cosmetics (can cause skin irritation and allergic reactions)
  • Carbomer - safe emulsifier and stabilizer
  • Phenoxyethanol - a preservative to stop bacterial growth, safely used in cosmetics
  • Imidazolidinyl Urea - a derivative of formaldehyde, safe in low doses (under 0.5% of total product mass), but linked to skin irritation and other side effects in about 1% of people, according to this imidazolidinyl review

Who could benefit from it and who probably won't

According to this clinical study of an alprostadil-based cream, topical gels have often been used to treat ED successfully. 32.6% of participants responded well to this topical testosterone cream too. But, there are no studies about the effects of l-arginine as a topical for treating ED. There are also no studies about the long-term side effects and safety concerns of topicals for ED.

Considering that any topical you put on your skin is directly absorbed into the area, we recommend some caution to protect your sensitive parts. And we encourage you to talk to a doctor before trying it.

Pricing

Is Viasil a good value?

Viasil is in the higher price range of similar natural supplements for ED. You can find comparable products starting at about $40, with some topping $70 per bottle. Deciding if Viasil is a good value for you depends on two main factors.

First, are you suffering from ED symptoms as an older man (not someone with a healthy sex drive looking for a boost)? Or are your symptoms caused by the addition of an SSRI to your wellness regimen? If you answered yes to either or both, Viasil could be worth a try. The ingredients in Viasil are well suited for both of these purposes.

Second, are you willing to try the gel despite a lack of clinical evidence regarding its efficacy and safety? A second product for free may add value, considering they’re meant to work in tandem, but in this case we recommend caution with the topical. Nonetheless, even if you never use the topical, the overall price of Viasil seems reasonable if you are an older adult male dealing with ED and a desire or need to avoid prescription options.

100-day money-back guarantee

One of the things that makes Viasil a fair value is the way they’ve structured their money-back guarantee. It gives you three months to try the product and decide if it’s right for you. If not, you can get a full refund minus any shipping charges you may incur. Some similar products offer shorter guarantees or only refund you for unopened products, but Viasil gives you a refund for all the boxes you order regardless of their status.

Is Viasil safe?

Our research found no reports of adverse reactions from taking Viasil. However, you should also be aware that you can find counterfeit versions of this supplement online. We are focused on the Swiss Research Labs version, available on their website and select retailers. Check the labeling carefully or read the ingredient list to ensure you’re getting the real deal.

The ingredients in Viasil are all-natural, and they exist in extremely low doses. You’ll still want to talk with a doctor beforehand. Some components can interact with prescription drugs, especially those for blood pressure, central nervous system management, and blood sugar. Red ginseng can potentially interact with caffeine in the short term and sleep over the long term.

How we evaluate health services

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service or product. But in general for health products and services, we have five broad areas that we explore in our evaluations, including:

Quality: How well does the company deliver its core service(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telemedical or teletherapy services, is the quality of the service high enough that we would recommend it to loved ones without hesitation? If not, why not? For health products, does the product or device meet a high level of safety? Is it manufactured with high quality standards? Has it – or have its ingredients – been subjected to studies that confirm effectiveness?

User-friendly: How intuitive and convenient is the service or product? Does the device, program, app, or website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money’s worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure? Does a company market your information?

Customer support: Particularly in situations where ‘one size fits all’ doesn’t make sense, how well does the company help to make the service or product ideal for you or address your individual needs?
