Maca is a vegetable from a cruciferae family. It grows only on the high slopes of the Andes in Peru and has been cultivated and consumed by the whole local population as far back as 2,000 years ago, who believed it to be the fountain of youth. Maca is eaten to balance the daily diet with its wide variety of minerals, amino-acids, vitamins, phenols and other components. Maca is thus one of the greatest natural food supplements in the world, in the current climate of an accelerated life-style and carelessness with respect to balanced nutrition.
