The evidence in words
The verdict
For testosterone, Maca earns evidence grade D (trivial effect, high consistency) — the evidence does not support the claim. No change
How it might work
Notably, maca improves libido and some sexual-function measures without changing testosterone or other sex hormones — its mechanism is non-hormonal and not fully understood.
How to use it
1.5–3 g/day of powder or extract; gelatinized forms digest more easily.
Safety & cautions
Well tolerated as a food.
Bottom line
A genuine libido aid that works without touching your hormones. 1.5–3 g/day if desire is the goal; not a testosterone lever.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
