One is a semen volume supplement, the other a blend aimed at taste, so the goals differ. Our editorial team at Trusted Health Reviews compares them.

In briefChecked October 2026
Semenax is our top pick among semen-volume supplements. A single small trial, funded by the company, found a modest rise in average ejaculate volume against placebo. SemEnhance is sold to improve semen taste using vitamin C, fruit powders, bee pollen and royal jelly. We found no published evidence that any supplement changes semen taste.
⚡ The short verdict
We pick Semenax, our top pick among semen-volume supplements. Its only trial is small and company-funded, and it showed no benefit for sperm quality, sexual function or orgasm. At most, expect a modest effect.
Leading Edge Health makes Semenax, a blend of 16 amino acid and herbal ingredients such as Swedish flower pollen, L-arginine, L-lysine, zinc, L-carnitine, maca and Butea superba. The sales pages give no amounts. Its sole trial analyzed 63 men over 2 months. Average ejaculate volume went from 2.49 to 2.97 ml, while placebo dropped slightly. Sperm count, motility and sexual function matched placebo. The company funded the trial, and the formula tested may not match today's. The 67-day guarantee runs from delivery.
The same company makes SemEnhance, a mix of vitamin C, pineapple, kiwi, banana, strawberry, celery, bee pollen and royal jelly. No amounts or directions are shown. The studies mentioned on its page concern sperm or oxidative markers rather than taste, and none used the product. Because it holds bee products, allergic reactions are possible. The 67-day guarantee runs from delivery.
For semen volume, Semenax is our top pick and the winner here. Order from the official site so the 67-day guarantee applies and you steer clear of counterfeits. Keep your expectations modest.
For volume, we pick Semenax, our top pick among semen-volume supplements. SemEnhance is aimed at taste, not volume, and no published evidence shows it works.
Semenax combines amino acids and herbs and is sold for semen volume. It has one small trial. SemEnhance combines fruit, vitamin C and bee products and is sold to change semen taste. It has no trial.
No one has studied them together. L-arginine and vitamin E in Semenax, and royal jelly in SemEnhance, can each affect blood-thinning medicines. If you take warfarin or something similar, ask a doctor first.
Order Semenax from the official website, since counterfeits are on record (Australia's TGA found a fake containing undeclared yohimbine). Under the guarantee, empty containers must be back within 67 days of delivery. Shipping isn't refunded, and each customer gets one refund.
Both are dietary supplements, not medicines. With Semenax, L-arginine can push blood pressure too low when combined with nitrates and adds to the effect of ED drugs and blood pressure medicines. L-arginine and vitamin E may also raise bleeding risk, and Semenax isn't advised if you have a pollen allergy. With SemEnhance, bee pollen and royal jelly can cause allergic reactions, some severe, and royal jelly may interact with warfarin.
