Maca (Lepidium meyenii) is a cruciferous root vegetable grown in the Peruvian Andes at 4,000–4,500 metres elevation. Used for millennia as food and medicine, it is now popular for libido enhancement, hormone support, and energy. Notably, it does not directly alter sex hormone levels in blood — its effects appear to be mediated through hypothalamic-pituitary axis modulation and glucosinolate compounds. Evidence is promising but trial sizes remain small.

Key Benefits

Libido enhancement (men & women)

⚠ Safety Notes

Generally safe as food. Thyroid concern: contains goitrogens (like other cruciferous vegetables) — those with thyroid conditions should cook/gelatinise. Not safe in hormone-sensitive cancers (limited data).
