Overview
Maca grows at 3,500–4,500m altitude in the Peruvian Andes — one of the highest-altitude crop plants in the world. Used by Inca warriors for energy and fertility for over 2,000 years. Multiple RCTs confirm improvements in sexual dysfunction and libido in men and postmenopausal women. Unlike hormone herbs, maca does not directly act on sex hormone levels — its unique glucosinolates (macamides, macaenes) work through adaptogenic, HPA axis, and pituitary-hypothalamic pathways.
Traditional Use
Maca has been cultivated in the Peruvian Andes for at least 2,000 years by the indigenous Quechua people. Inca warriors consumed maca before battle for strength and endurance. After conquering a region, Inca rulers would restrict maca use to prevent men from becoming too virile and difficult to control — a historical reference to its documented libido-enhancing effects. Traditional use covered fertility, energy, hormonal health, and as a staple food providing complete nutrition at high altitude where few other crops survived.
Key Active Compounds
Macamides and Macaenes
Unique fatty acid derivatives and polyunsaturated acids found only in maca. These compounds modulate the endocannabinoid system and act on the HPA (hypothalamic-pituitary-adrenal) axis, explaining the adaptogenic and sexual function effects without direct hormonal activity.
Glucosinolates and Isothiocyanates
As a cruciferous plant, maca contains glucosinolates with thyroid and hormonal modulating effects. These may contribute to the adaptogenic hormonal-balancing effects.
Alkaloids (Macaridine, Lepidiline A&B)
Minor alkaloids contributing to the neurological and hormonal effects.
Evidence-Based Benefits
Sexual Function and Libido
Moderate evidenceMultiple RCTs confirm improvements in sexual dysfunction in men (including SSRI-induced sexual dysfunction), menopausal women, and healthy subjects. A 2010 Cochrane-style review found consistent evidence for libido enhancement.
Menopausal Symptoms
Moderate evidenceClinical trials show significant reduction in hot flashes, night sweats, depression, and anxiety in perimenopausal women. Works without directly increasing estrogen levels — important for women with hormone-sensitive conditions.
Energy and Mood
Moderate evidenceRCT showed significant improvement in energy, mood, and reduction of depression and diastolic blood pressure in postmenopausal women. Athletes report improved endurance and recovery.
Common Preparation Methods
Maca Powder in Smoothies/Food (Most Common)
Add 1–3 teaspoons of gelatinized (preferred) or raw maca powder to smoothies, oatmeal, or blend into warm non-coffee drinks.
Dosage: 1–3 teaspoons (5–15g) dailyGelatinized maca (pre-cooked) is more digestible than raw powder and has better bioavailability. Traditional Andean preparation always involved cooking the root. Start with 1 teaspoon and increase to 3 over 2 weeks. Takes 6–12 weeks for full effects.
Capsules
Take standardized maca root capsules.
Dosage: 1500–3000mg daily (3 x 500mg or 1000mg capsules)Convenient for consistent dosing. Best to use gelatinized powder in capsule form for digestibility.
