Product Introduction:
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 Peru 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.
Maca is used for “tired blood” (anemia); chronic fatigue syndrome (CFS); and enhancing energy, stamina, athletic performance, memory, and fertility. Women use maca for female hormone imbalance, menstrual problems, and symptoms of menopause.

Main Function
1) Sexual Function
In a 2008 study from CNS Neuroscience & Therapeutics, researchers found that maca may help alleviate sexual dysfunction caused by use of selective-serotonin reuptake inhibitors (or SSRIs, a class of medications used in the treatment of depression).  
2) Fertility
One small study looked at the effect of 4 months of treatment with maca tablets on semen quality in nine adult men. Treatment with maca resulted in increased semen volume, sperm count, and sperm motility. Serum levels of testosterone and estradiol were not affected.
There are different types of maca, including yellow, black, and red maca. Black maca appears to have the greatest effect on sperm count, followed by yellow maca, which has moderate effects.
3) Mood in Menopause
Maca may help ease anxiety and depression in postmenopausal women, according to a 2008 study from the journal Menopause. For the study, 14 postmenopausal women took 3.5 grams of powdered maca for six weeks and then took a matching placebo for another six weeks. Study results showed that maca helped reduce anxiety and depression, as well as improve sexual function.
