Don't use maca if you have too much energy.  :)

What's maca?

Maca is a plant that grows in central Peru in the high plateaus of the Andes Mountains. It has been cultivated as a vegetable crop in this area for at least 3000 years. Maca is a relative of the radish and has an odor similar to butterscotch. Its root is used to make medicine. People take maca by mouth for "tired blood" (anemia); chronic fatigue syndrome(CFS); and enhancing energy, stamina, athletic performance, and memory. People also take maca by mouth for female hormone imbalance, menstrual problems,symptoms of menopause, improving fertility, and sexual dysfunction caused by antidepressants, weak bones (osteoporosis), depression, stomach cancer, leukemia,HIV/AIDS, tuberculosis, erectile dysfunction (ED), to arouse sexual desire, and to boost the immune system.In foods, maca is eaten baked or roasted, prepared as a soup, and used for making a fermented drink called maca chicha.In agriculture, it is used to increase fertility in livestock.  (Wait, what?)

**********************************

One of the awesome benefits of maca is that it is rich in iodine and that can be good for the thyroid. But, extremely high doses of iodine can actually have a negative effect and even worsen the symptoms of thyroid disease.[3] It’s one of the reasons why taking iodine supplements, can promote goiter and negative effects on the thyroid. Remember, enjoying everything in moderation is always the best route. 

(I use gelatinized maca, less than a tablespoon, not every day.)

Smells like butterscotch but works like medicine. Sweet!

Maca chicha sounds good!
