The Formula
What Ingredients Are in Erexafil?
Erexafil discloses its three nutrients but places nine botanicals in a single 545 mg proprietary blend, so the individual herb doses are hidden. Below is each ingredient, its intended role, and what the evidence suggests.
🌿
Korean Ginseng (Panax ginseng) Proprietary blend
The most evidence-backed ingredient here for sexual function. A systematic review of Korean red ginseng for erectile dysfunction found a positive effect, though the underlying studies were small and of low methodological quality, so the evidence is suggestive rather than definitive. The limitation: it sits inside a 545 mg proprietary blend shared with eight other herbs, so the actual ginseng dose is undisclosed and may be well below the amounts used in research.
🌱
Ashwagandha (Withania somnifera) Proprietary blend
A well-researched adaptogen. A randomized controlled trial in aging, overweight men found ashwagandha modestly raised testosterone (~15%) and DHEA-S (~18%) - but notably, it showed no significant advantage over placebo for fatigue, vigor or sexual well-being in that group. So it may support stress and hormones somewhat, but a real-world vitality benefit is unproven, and its dose here is undisclosed.
🥼
Horny Goat Weed (Epimedium) Proprietary blend
A traditional aphrodisiac whose active compound (icariin) has shown mild PDE5-like activity in laboratory and animal studies - the same broad pathway targeted by ED drugs, but far weaker and largely unproven in humans at supplement doses. Popular and plausible in theory, but human evidence is limited, and the dose in Erexafil is hidden within the blend.
⚠
DHEA (Dehydroepiandrosterone) Proprietary blend
This is a HORMONE, not an herb - a precursor the body converts to testosterone and estrogen. That makes it the most consequential ingredient to understand. DHEA is banned in competitive sports, is prescription-only or restricted in several countries (Canada, UK, Australia), and can cause side effects (acne, hair changes, mood changes) and hormonal effects. It should be avoided by men with prostate or hormone-sensitive conditions without medical advice. Its undisclosed dose is a real concern for a hormone.
🌿
Tribulus Terrestris Proprietary blend
A popular 'testosterone booster' - but here honesty matters most. A randomized controlled trial found Tribulus does NOT raise testosterone, androstenedione or LH in men, and reviews find little robust evidence it increases testosterone. It may have modest effects on erectile function in some studies, but as a testosterone booster the evidence is largely negative. Its inclusion is more marketing than science.
🌱
Mucuna Pruriens Proprietary blend
A bean extract naturally containing L-dopa, a dopamine precursor. Dopamine plays a role in libido and mood, giving a plausible rationale, and there is some research in male fertility contexts. But evidence for sexual performance in a supplement blend is limited, and the L-dopa content raises interaction concerns with certain medications - another reason the undisclosed dose matters.
🌳
Muira Puama Proprietary blend
Known as 'potency wood,' a traditional Amazonian aphrodisiac. Despite its reputation, rigorous human evidence is very limited - it rests largely on tradition and small, older observational reports rather than controlled trials. A plausible but essentially unproven inclusion at an unknown dose.
🍂
Ginkgo Biloba Proprietary blend
Included for its circulation-supporting reputation, since blood flow is central to erections. However, controlled trials of ginkgo for sexual function (including antidepressant-related dysfunction) have been largely disappointing. It also affects blood clotting, which matters if you take blood thinners. A circulation-themed addition with weak sexual-health evidence.
💎
Boron (Citrate Complex) Proprietary blend
A trace mineral studied for possible effects on testosterone and hormone metabolism, with some small studies suggesting modest hormonal shifts. It's a reasonable, low-risk inclusion, but the evidence is preliminary and the amount here is undisclosed within the blend.
☀
Vitamin D3 (Cholecalciferol) 50 mcg (250% DV)
A fully disclosed, well-dosed nutrient. Vitamin D supports testosterone and general male health - but mainly if you are deficient. Correcting a genuine deficiency can help; taking extra when you're already replete generally does not boost testosterone. A sensible foundational nutrient at a solid dose.
⚡
Niacin (Vitamin B3) 12 mg (75% DV)
Disclosed and reasonably dosed. Niacin supports normal energy metabolism and can support blood-vessel function (it's used medically at much higher doses for cholesterol). At this dose it's a supportive nutrient for energy and circulation rather than a powerful active.
🔧
Zinc (Bisglycinate) 11 mg (100% DV)
A fully disclosed, well-chosen form at 100% of the daily value. Zinc is important for testosterone and male reproductive health - deficiency lowers testosterone, and correcting it helps. Like D3, its benefit is mainly about preventing or correcting a deficiency rather than supercharging a healthy man. A solid foundational inclusion.
The theme: a sensible-looking men's-wellness line-up with mixed evidence - Korean ginseng and ashwagandha have some support, tribulus doesn't raise testosterone, and DHEA is a hormone to be careful with. The proprietary blend hides every herb dose, so effectiveness can't be verified.
