A: Whole World Botanicals does not sell Royal Maca as a weight-reduction supplement. To do that, we would need evidence from a well-designed study. However, there is evidence that maca root, in extract or concentrate form, improves Insulin Growth Factor (Igf) in the tissues. 
This is amazing and extraordinary. No other food has been found to cause an increase in this precursor hormone produced by the pituitary. And there are great problems in giving someone Igf manufactured in the laboratory in their food because it gets destroyed in the gut.
Adequate levels of Igf are correlated with enhanced lipid (fat) digestion by the liver, with decreased fat storage, increased muscle mass and increased energy. As we get older, our Igf decreases, which causes a decrease in Human Growth hormone. Some of our customers email or call us claiming weight loss after using Royal Maca for several months. But as we started out by saying, no claims can be made until we have at least one good study.
