Peruvian root supporting energy, libido, and hormonal balance.
By Suplagen Team · Updated
What it is
Maca (Lepidium meyenii) is a Peruvian cruciferous root vegetable used as a food and adaptogen. Different color varieties may have different effects.
How it works
Does not directly contain hormones; may support HPG axis signaling and neurotransmitter balance through unique macamides and glucosinolates.
What the evidence says
Emerging evidence for libido and energy; moderate evidence for sexual dysfunction. Does not directly raise hormone levels.
How much to take
The catalog range is 1,500 to 3,000 mg daily, with 3,000 mg as the ceiling. Two capsules is typical; gelatinized maca digests more easily than raw.
The evidence is moderate for sexual dysfunction and emerging for libido and energy. One fact to keep in mind: maca does not directly raise hormone levels, whatever the marketing implies.
When and how to take it
With food, in the morning. Allow 6 to 8 weeks for effects, and cycle it: 8 to 12 weeks on, 2 to 4 weeks off.
Tongkat ali vs maca separates the two supplements people confuse most in this category.
Who should skip it
Thyroid conditions are a contraindication: maca is cruciferous and contains goitrogens. Hormone-sensitive cancers are a caution. One mild interaction: hormone therapy. Pregnancy safety isn't established.
