Maca is a Peruvian root vegetable with a long history at high altitude and a modern reputation for energy, mood, and libido. Unlike many trendy supplements, several of its uses have human studies behind them.
What it's actually good for
Energy and stamina — maca is nutritive (it's a food, eaten like a root vegetable in Peru) and commonly reported to give steady, non-stimulant energy.
Mood — small trials suggest benefits for mood and reduced anxiety symptoms, including in postmenopausal women.
Libido — its best-researched use: multiple studies report improved sexual desire in both men and women.
How to choose and take it
Gelatinized vs raw: gelatinization removes starch, making it gentler on digestion — recommended for most people.
Colors: yellow is the everyday all-rounder; red is traditionally favored for women's health; black for stamina and men's fertility. The differences are real but modest — don't overthink it.
Dose: studies typically use 1.5–3g per day. It's food-like, so it pairs fine with breakfast or smoothies.
