General composotion of Maca

Maca is a high-grade food because it consists mainly out of carbohydrates (60-75%), proteins (10-14%), fibres (8,5%) and lipids (2%).
 
The carbohydrates in Maca mainly consist of amino acids. The amino acids arginine and lysine effect the regulation of fertility, for both men and women. The reproductive cells of men contain a large amount of arginine. Maca fills up the arginine in these cells and in doing so, helps relieve fertility problems and a shortage of libido. Lysine helps women with fertility problems and menopausal complaints.

Maca grows only in soil that is rich of minerals. That's why the plant contains a lot of minerals: calcium, magnesium, potassium, iron, silica and traces of iodine, manganese, zinc, copper and sodium.

Because Maca also contains fructose, it can also fight fatigue. Sperm plasma also uses this fructose to supply the spermatozoids with energy.

There are also sterols in Maca. An improvement of menopausal problems and an increase of the female fertility are caused by these sterols and by the amino acid lysine.
They also found glucosinolates in the plant. Plants that contain glucosinolates are used all over this world because they have an effect on hormonal reproductive actions.
