How does Royal Maca balance hormones?

In December 2004, scientists from the Albany Medical College in Albany, New York, discovered that Maca root helps raise the tissue levels of IGF-1 (Insulin Growth Factor).

Maca is the only food plant in the world known to have this hormone stimulating-balancing effect on the human endocrine gland system.  Maca itself does not work by providing plant hormones to the human body. It works by helping the body make its own hormones more adequately.
