Maca Root
Also known as: Lepidium meyenii, Peruvian Ginseng, Maca Extract
A Peruvian adaptogenic root with evidence for libido, sexual function, and energy — without altering sex hormone levels.
What it is
Maca (Lepidium meyenii) is a cruciferous root vegetable native to the Peruvian Andes, cultivated for thousands of years as both a food and medicinal plant. It is classified as an adaptogen and has gained significant popularity for applications in sexual health, libido, menopausal symptoms, and energy. Uniquely, its effects on libido and sexual function appear to be independent of changes in testosterone, estrogen, or other sex hormones — a mechanism not yet fully understood.
How it works
Macamides and glucosinolates are the primary bioactive compounds. Maca does not appear to act via hormonal pathways (human trials consistently show no change in testosterone, LH, FSH, or estrogen). Its mechanisms likely involve CNS modulation (dopaminergic and serotonergic pathways related to libido), antioxidant activity, and possibly direct action on the hypothalamus. Effects on sexual desire take approximately 4–8 weeks to manifest.
Clinical dose range
1,500–3,000 mg/day (whole root powder or extract equivalent)
Most clinical trials use 1,500–3,000 mg/day of gelatinized maca (which has better digestibility and absorption than raw). Color variants (yellow, red, black) may have different applications: black maca appears more beneficial for men (sperm quality); red maca studied for prostate health.
Forms comparison
What to look for on the label
- Gelatinized form specified for better tolerability
- Maca color variant stated if specific application targeted (black = male function, red = female)
- Third-party tested for heavy metals
- Organic certification if sourced from Peru (soil contamination is a concern)

Safety & dosing notes
Generally very well tolerated as a food-like supplement. GI discomfort with raw powder — gelatinized form preferred. Theoretical concern (unproven) about glucosinolate effects on thyroid in very high doses — not a clinical concern at typical supplemental doses. Avoid in hormone-sensitive conditions due to incomplete mechanism understanding.
SuppsBuddy validates maca as a generally safe, food-category supplement and flags non-gelatinized products for potential digestive concerns. Heavy metal testing is particularly important for root supplements sourced from Andean soils.

What forms of Maca Root should I look for?
Gelatinized Maca (heat-treated): Starch removed for better digestion and absorption; preferred for GI sensitivity | Raw Maca powder: Traditional form; higher glucosinolate content but harder on digestion | Maca extract (concentrated): Concentration varies; verify equivalent raw dose
