What it is. The hypocotyl/root of Lepidium meyenii (Andean “maca”), sold as powders, capsules, and extracts for energy, fertility, and libido marketing — including in multi-herb “male enhancement” blends.

Why the stricter rating. MamaKind marks Avoid for pregnancy and breastfeeding for concentrated maca supplements (not the same as occasional traditional food use). Why: (1) Health Canada’s Natural Health Product monograph requires “ask a health care practitioner before use if you are pregnant or breastfeeding.” (2) Health Canada’s Food Directorate assessment of maca root extract flagged missing reproductive and developmental toxicity data for sensitive groups, including people who are pregnant or trying to conceive. (3) A USP dietary-supplement safety review notes that Natural Medicines advises avoiding maca in pregnancy and lactation because safety information in those populations is lacking. Commercial extract doses and multi-ingredient blends are not the same exposure as traditional cooked Andean food — so we do not treat maca capsules as cleared for perinatal use. Ask your clinician if you have a specific reason to use maca.
