Maca powder, which is made from the Maca root, comes from the Andes in Peru. This root, which has also been branded as one of the "superfoods" and sometimes referred to as "Peruvian gold" has been used for generations by the Indians in Peru to increase fertility in both animals and humans. Today, Maca is used as an energiser, as a cure for hormonal imbalances, to promote mental clarity and also as an aphrodisiac (grrr).
There has been studies on Maca which shows that taking 3.0 g Maca daily relieves sexual dysfunction and it is said to also increase muscle-bulding as an alternative to silly steroids.
Basically, it does everything except calling you baby and buying you a drink. If you want to know more about the wonders of Maca click here or here.
All I know is that tastes good and that I might have some more. Everyday.
