Summary of Findings:


The study used a combination formulation known as Maca-GO with the aim of the study to determine toxicity of and to assess various effects of Maca-GO systemically. 

  1. The toxicity was > 15 g/kg of body weight in mice and > 5 g/kg body weight in rats, a dose much higher than would be administered in humans and would be classified as non-toxic.

  2. In rats with functioning ovaries and after ovariectomy, a reduction in estradiol and progesterone levels were observed. 

  3. Maca-GO provided anti-depressant effects, improvements in cognitive function, reductions in cortisol, ACTH, total cholesterol, and triglycerides.
