Men’s sexual health supplements are a crowded market full of bold promises. This guide compares four of the best-known formulas, explains what the research on their herbal ingredients actually shows, and flags the safety issues every buyer should know.
First, a word about erectile problems
Occasional difficulty is normal. Persistent erectile dysfunction is different: it can be an early warning sign of heart disease, high blood pressure or diabetes, because the same blood vessels are involved. If problems are frequent, see a doctor before trying any supplement. Prescription treatments are well studied and effective for most men.

The quick comparison
| Product | Positioned for | Standout detail | Our take |
|---|---|---|---|
| VigRX Plus | Erection quality, desire, satisfaction | Maker-funded placebo-controlled trial; 67-day guarantee | The best-documented option in this group |
| ProSolution Pills | Overall sexual performance | Herbal blend taken daily rather than on demand | Reasonable alternative; check interactions |
| Semenax | Semen volume and fertility support | Amino acid and herbal formula | Evidence is thin; manage expectations |
| Extenze | Male enhancement, widely sold in stores | Easy to find at retailers | Buy only from authorized sellers |
Products we compared
Top pick
VigRX Plus
A daily herbal formula taken as one capsule twice a day with meals. The listed ingredients include Asian red ginseng, damiana, muira puama, hawthorn berry, catuaba bark, saw palmetto, ginkgo biloba and BioPerine.
- The manufacturer cites a placebo-controlled clinical trial run by Vedic Lifesciences
- 67-day money-back guarantee: try it for 60 days and return the empty containers within 67 days of delivery (shipping not refunded, one order per customer)
- One box lasts 30 days, so a fair trial means ordering at least two
Alternative
ProSolution Pills
A daily herbal supplement aimed at overall sexual performance and confidence.
- Check the full ingredient list for herbs that interact with blood pressure or blood-thinning medication
- Compare the guarantee length with VigRX Plus
- Like all daily formulas, give it several weeks before judging
Specialist
Semenax
Marketed specifically for semen volume and ejaculation intensity rather than erections.
- Human research on “volume” formulas is limited; treat claims cautiously
- Men trying to conceive should see a fertility specialist; a semen analysis is inexpensive and informative
- Buy direct to make sure the guarantee applies
Retail brand
Extenze
One of the most recognizable names in the category, sold online and in many stores.
- Buy only from the official site or authorized retailers to avoid counterfeits
- Read the label closely and check for stimulants if you are sensitive to them
- Set realistic expectations: marketing in this category often goes further than the evidence
What the research says about common ingredients
Korean red ginseng is the best-studied herb in this category. A Cochrane review found that ginseng may produce a small improvement in erectile function in men with mild to moderate problems, but the evidence is low certainty. Read our full Korean red ginseng review.
L-arginine helps the body make nitric oxide, which relaxes blood vessels. Some small trials, often combining it with pine bark extract (pycnogenol), reported benefits in mild erectile dysfunction.
Maca, tribulus, muira puama and damiana have traditional use and a few small studies on desire, but the research is limited and inconsistent.
Ginkgo biloba has not shown consistent benefits for erectile function in controlled trials, and it can increase bleeding risk alongside blood thinners.
The safety issue most buyers don’t know about
The U.S. Food and Drug Administration has repeatedly found “natural” male enhancement products that secretly contain prescription drugs such as sildenafil or tadalafil, sometimes at unsafe doses. These hidden ingredients can dangerously lower blood pressure in men who take nitrates for heart conditions. Read how to buy male enhancement supplements safely.
To protect yourself:
- Buy established brands from their official websites or authorized retailers
- Avoid products sold as single “gas station” pills or that promise effects within minutes
- Check the FDA’s public list of tainted products before buying an unfamiliar brand
- Never take these supplements alongside nitrate medication without your doctor’s approval

Which male enhancement supplement is best?
Among the products we compared, VigRX Plus has the most published documentation and a clear 67-day guarantee, which is why it is our top pick. No supplement works as reliably as prescription treatment.
Do male enhancement pills increase size?
No supplement has been shown to permanently increase penis size. Be skeptical of any product that suggests otherwise.
How long before I see results?
Daily herbal formulas are designed to be taken for weeks, not minutes. Most manufacturers recommend at least 60 days.
Can I take these with blood pressure medication?
Several herbs in these formulas can affect blood pressure or bleeding. Ask your doctor or pharmacist before combining them with any prescription medication.
