Scientific background
Independent researchTongkat ali (Eurycoma longifolia)
Tongkat ali (Eurycoma longifolia) is a Southeast Asian shrub whose root extract is marketed for male vitality1.
Horny goat weed (Epimedium, icariin)
Horny goat weed (Epimedium species) contains icariin, which inhibits the enzyme PDE5 in laboratory studies, the same target as erectile-dysfunction medicines.
Fenugreek (Trigonella foenum-graecum)
Fenugreek seed extracts, rich in saponins, are marketed for male vitality and testosterone.
Research evidence
Independent researchTongkat ali (Eurycoma longifolia)
A meta-analysis of clinical trials found that tongkat ali supplementation increased total testosterone in men, particularly in men with low testosterone, but concluded that more research is needed before clinical use1.
Horny goat weed (Epimedium, icariin)
Evidence for benefits comes mainly from laboratory and animal studies; robust human trials are lacking.
Fenugreek (Trigonella foenum-graecum)
A 2026 meta-analysis of randomised trials found a possible small effect on total testosterone, with very uncertain evidence and no stable benefit for free testosterone; it concluded that current evidence does not support testosterone-boosting claims2.
