BioPerine® is a patented extract derived from black pepper fruit (Piper nigrum), standardized to contain 95% piperine. It is the only nutrient absorption enhancer of its kind to undergo clinical study in the United States — and it’s what sets VigRX Plus® apart from formulas that simply stack herbs without considering how well the body absorbs them.

Added to VigRX Plus®, BioPerine® increases the bioavailability of all co-ingested nutrients by up to 30%. In practical terms: every herb in this formula reaches your bloodstream more effectively because of BioPerine® — making the entire supplement significantly more potent than it would be without it.

Research published by Sabinsa Corporation — the manufacturers of BioPerine® — demonstrates enhanced absorption of both fat-soluble and water-soluble nutrients, including B vitamins and selenium, in healthy individuals when taken alongside piperine. This is why BioPerine® appears in the formula first: it’s the foundation everything else is built on.

Damiana (Turnera diffusa) has been used as a natural aphrodisiac for generations across Mexico and Central America. Herbalists have long recommended it specifically for men experiencing low libido or reduced sexual interest — a reputation backed by its active flavonoids, which are believed to support blood flow and sexual response.

Tribulus Terrestris, commonly known as Puncture Vine, is one of the most extensively studied herbs in male sexual health. It has been shown to support healthy testosterone production, improve sexual drive, enhance stamina, and reduce the incidence of erectile difficulties — making it a high-value addition to any male enhancement formula.

Together, these two herbs address both the psychological and physiological sides of libido: desire and the hormonal foundation that sustains it.

Epimedium (Epimedium grandiflorum), widely known as Horny Goat Weed, has been a cornerstone of traditional Chinese medicine for over 2,000 years. Its active compound, icariin, has been studied for its ability to inhibit PDE-5 — the same enzyme targeted by prescription erectile dysfunction medications — supporting stronger, more reliable erections through a natural mechanism.

Ginkgo Biloba is one of the most thoroughly researched plants in the world. In the context of male sexual health, its primary value lies in vasodilation — the widening of blood vessels to improve circulation. Research has specifically demonstrated Ginkgo’s effectiveness in men experiencing sexual dysfunction as a side effect of antidepressant medications, where improvements in desire, arousal, and orgasm were observed at doses of 60–120mg.

Together, these two extracts work on both the vascular and neurological pathways of sexual response — supporting blood flow where it matters most.

Korean Red Ginseng (Panax ginseng) is among the most well-researched herbs in natural medicine, with a history of use spanning over 5,000 years. In the context of male sexual health, it has been studied specifically for its ability to improve erectile function, boost sexual stamina, and support healthy circulation — including blood pressure regulation.

Ginsenosides, the active compounds in Red Ginseng, are believed to promote nitric oxide production, which relaxes blood vessel walls and allows for improved blood flow to penile tissue — supporting firmer, more sustained erections.

Multiple clinical studies have examined Panax Ginseng’s effect on erectile dysfunction, with several showing statistically significant improvements in erection quality, sexual desire, and overall satisfaction in participants compared to placebo.

Note: Men with cardiovascular conditions or those taking heart medications should consult a physician before use.

Hawthorn Berry (Crataegus monogyna) is rich in oligomeric proanthocyanidins (OPCs) and flavonoids — naturally occurring compounds that have been shown to support cardiovascular health, healthy blood pressure, and arterial flexibility.

Its relevance to male sexual performance is direct: erections are fundamentally a vascular event. The strength and reliability of an erection depend on healthy blood vessel function and adequate blood flow into penile tissue. Hawthorn Berry supports both by relaxing and expanding the coronary blood vessels, improving overall circulation without the risks associated with pharmaceutical vasodilators.

As a long-term cardiovascular tonic, Hawthorn Berry also contributes to the sustained, cumulative benefits that VigRX Plus® users report with continued use — making it a key ingredient for men over 40 whose circulation may have begun to decline with age.

Saw Palmetto (Serenoa repens) has been used for decades in men’s health for its well-documented role in supporting prostate health and regulating dihydrotestosterone (DHT) levels. Balanced hormonal health is the underlying foundation of consistent sexual drive — making Saw Palmetto one of the most important long-term ingredients in the VigRX Plus® formula.

Muira Puama bark extract — often called “potency wood” across South America — is a natural stimulant with a growing body of research behind it. Studies have found it effective in improving male potency and increasing sexual desire in men experiencing reduced libido, with a strong safety profile and no known adverse effects at supplemental doses.

Catuaba Bark is a prized plant from the Brazilian rainforest, long valued for its strong aphrodisiac and nerve-stimulating properties. It works through two mechanisms: vasodilation to improve blood flow to sexual organs, and direct stimulation of the central nervous system to enhance sensitivity, arousal, and sexual response. Users often describe a noticeable increase in sensation and energy.
