Who Manufactures Viasil?

The manufacturer of this male enhancement product is Swiss Research Labs, an American company that is focused on improving its customer’s sex life.


*All individuals are unique. Your results can and will vary.

The company claims to use 100% natural ingredients so as to prevent risks and dangers presented by prescription medications that improve low libido and erectile dysfunction.

Additionally, the proprietor supposedly subjects Viasil to third-party testing before production to further ensure its safety.

How Does Viasil Work?

Viasil is a dual action formula that works to circulate blood and improve energy levels by boosting nitric oxide and ATP production.

Nitric oxide is a crucial element that enhances blood flow into the penis. By relaxing the inner walls of the blood vessels, nitric oxide allows more blood to flow into them. With more blood flow erections become stronger and long-lasting.

As for ATP production, Viasil enhances its levels in the blood thus increasing the body’s energy levels. This spike in energy levels increase strength and endurance during sex.

What are the Ingredients of Viasil?

Horny goat weed

Horny goat weed is a natural aphrodisiac that is known to promote blood circulation in the body.


*All individuals are unique. Your results can and will vary.

A chapter in the book of Phytopharmacy provides clinical evidences that support the effectiveness of horny goat weed in treating sexual dysfunction. According to the studies, this aphrodisiac treats impotence in men and low libido in women[1].

Ginkgo biloba

Similar to horny goat weed, Ginkgo biloba is an herb that improves blood flow to the penis[2].

According to studies in the Archives of Sexual Behavior ginkgo biloba extract facilitates blood flow, influences nitric oxide systems, and has a relaxant effect on smooth muscle tissue.

Tribulus terrestris

Tribulus terrestris is known to improve sex drive by regulating blood sugar and cholesterol as they alter hormones[3].

Studies in the Oxidative Medicine and Cellular Longevity journal claim that Tribulus terrestris is a potential stimulator of testosterone production. These clinical studies confirm this herb’s ability in improving libido as well as sperm production.

Panax ginseng root

We documented in our Best Penile Cream Moisturizers article containing this ingredient. Panax ginseng root extract is believed to reduce stress and enhance sexual performance[4].

According to a study in the Cochrane Database Systematic Review journal, ginseng contains various chemical compounds that may have positive effects on erectile dysfunction. Ginseng supposedly works through stimulating NO production and causing sexual arousal.


Zinc is an essential mineral in protein synthesis that helps to regulate male hormones[5].

An article by researchers from the University of Kelaniya aimed to study the effects of zinc supplementation on sexual competence. The study found that supplementation of 5mg of zinc per day for 2 weeks increased ejaculatory latency, penile thrusting, and testosterone levels compared to the control group.

Potential Side Effects of Using Viasil

  • Nausea and vomiting
  • Insomnia
  • Dizziness

How is Viasil Unique from the Competition?

Viasil works is dual action as it supports blood circulation and ATP production. It also uses natural ingredients only in its formula.

Bottom Line

Viasil is a male enhancement supplement that has been crafted from natural botanicals, extracts, and minerals. It aims to improve blood flow to the penis thus supplying more oxygen and nutrients to the penile chambers, improving erections and with that, sexual performance.

Viasil works by boosting NO and ATP production, both which are vital for male sexual health. NO aids vasodilation while ATP boosts energy levels thus improving strength, performance, and endurance in the bedroom.

According to its makers, Viasil does not cause any side effects. In fact, it is claimed to prevent symptoms associated with testosterone boosting products such as mood swings, weight gain, and increased blood sugar.

However, ingredients such as horny goat weed and ginkgo biloba are known to cause mild to severe effects such as nausea, dizziness, difficulty in breathing, headaches, diarrhea, constipation, and allergies.

If you are allergic to any of the ingredients, it is safer to go for alternatives by other brands. Some of the highly rated male enhancement supplements include: Male Extra, Max Performer, Performer8, TestoPrime, Semenax, and VigRX Plus.

You can also purchase doctor recommended male enhancement pills online or get prescription drugs to treat erectile dysfunction.

Nevertheless, male enhancement supplements may only provide temporary solutions to your sexual dysfunction. If you want to tackle erectile dysfunction once and for all, then a visit to the doctor is the way to go.

With countless male enhancement supplements available on the market today it seems impossible to find "the right one." Sexual performance declines naturally as men age, which may contribute to feelings of inadequacy or embarrassment. Male enhancement supplements should be based on four key factors: active ingredients, ability to support sexual stamina, enhance arousal, improved* sexual desire and backed by clinical studies.

Below you'll find some of the most effective male enhancement supplements on the market today, in our opinion.

  1. Frederick T

    Viasil comes with side effects for me!!
    Doesn’t seem to live up to its reviews. Don’t really notice any difference in stamina or libido change. But this Viasil triggered side effects and caused allergic reactions while interacting with other drugs.
