Grown at 4,000 metres, where almost nothing else will. Maca is a root vegetable from the Peruvian Andes — Lepidium meyenii, an odd member of the brassica family that tolerates frost, thin soil, and ultraviolet light strong enough to burn most crops. The Inca cultivated it. The Spanish recorded it as trade goods. Modern interest centres on its macamides and glucosinolates, compounds that don't occur outside this plant family. 1,250mg per tablet, from a single cooperative in the Junín region — the highland province where maca has been grown longest and where the soil suits it best. One source, rather than a blend of whatever was cheapest that quarter. Maca holds no authorised UK health claims. What we can tell you is where it grew, who grew it, and exactly how much is in the tablet. One tablet daily with food, or two once you've found your feet with it. Sixty tablets, vegan, allergen-free.
