Q: What is maca root?

A: Maca (Lepidium meyenii) is a root vegetable, indigenous to Peru, that grows in the Andes Mountains. It is a nutrient-dense root containing significant amounts of iron, copper, zinc, amino acids, and vitamins B, C, and E. Historically, it has been baked, roasted, or added to soups. Today it is often found in powder form, in capsules or as a liquid extract.

Sometimes called Peruvian ginseng, maca root is an adaptogen that has been used for centuries to improve fertility, sexual function, and to boost stamina and energy. Although research is limited, small studies suggest maca may improve sperm volume, motility, and count in healthy males. Preliminary research has also reported that maca consumption may support an increase in feelings of sexual desire in healthy males. In addition, two small clinical studies reported that 3.3 or 3.5 grams of maca powder for six weeks was linked with lower anxiety, depression and sexual dysfunction, versus placebo. Researchers purport that maca may also help relieve menopause-related symptoms. As always, EN recommends talking with your health care provider before starting any new supplement or changing your daily regimen.
