What Is Maca Root?
Maca has been cultivated in the Peruvian Andes for over 3000 years as a food and medicinal plant. It is unique among libido supplements in that it does not measurably change testosterone or oestrogen levels — its benefits on sexual function and mood appear to be mediated by macamides and macaenes acting on the central nervous system.
How It Works: The Science
Macamides (fatty acid amides) are unique to maca and act as endocannabinoid system modulators and inhibitors of fatty acid amide hydrolase (FAAH). Glucosinolate metabolites influence serotonin and dopamine pathways. Black maca has specific evidence for sperm production; red maca for prostate and menopausal symptom relief.

Dosage Guide
Effective Dose
1.5–3g / day
1.5–3g/day of raw powder or 500–1000mg gelatinised extract. Gelatinised (precooked) is easier to digest. Black maca for male fertility; red maca for female health; yellow maca for general use. Benefits accumulate over 4–6 weeks.
Safety Profile & Side Effects
Extremely safe as a food. Goitrogenic potential (inhibits thyroid function) at very high doses — theoretical concern, not observed at normal supplement doses. Not recommended in hormone-sensitive cancers.
Who Should (and Shouldn't) Take It
Those experiencing reduced libido, couples trying to conceive, women going through menopause, and anyone wanting energy and mood support from a food-based adaptogen.
