Overview

Overview Information

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), improving fertility, sexual dysfunction, and other conditions, but there is no good scientific evidence to support these uses.

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.

How does it work?

Maca root contains many chemicals, including fatty acids and amino acids. However, there isn't enough information to know how maca might work.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Sexual problems caused by antidepressants (antidepressant-induced sexual dysfunction). Early research suggests that taking maca twice daily for 12 weeks slightly improves sexual dysfunction in women taking antidepressants.
  • Conditions in a man that prevent him from getting a woman pregnant within a year of trying to conceive (male infertility). Early research shows that taking a specific maca product daily for 4 months increases semen and sperm count in healthy men. But it's not clear if this results in improved fertility.
  • Health problems after menopause. Early research shows that taking maca powder daily for 6 weeks slightly improves depression and anxiety in postmenopausal women. It might also improve sexual problems. But these benefits are very small.
  • Increasing sexual desire in healthy people. Early research shows that taking a specific maca product daily for 12 weeks can increase sexual desire in healthy men.
  • "Tired blood" (anemia).
  • Leukemia.
  • Chronic fatigue syndrome (CFS).
  • Improving energy and athletic performance.
  • Improving memory.
  • Depression.
  • Female hormone imbalance.
  • Menstrual problems.
  • Symptoms of menopause.
  • Osteoporosis.
  • Stomach cancer.
  • Tuberculosis.
  • Boosting the immune system.
  • HIV/AIDS.
  • Other conditions.
More evidence is needed to rate the effectiveness of maca for these uses.

Side Effects

Side Effects & Safety

When taken by mouthMaca is LIKELY SAFE for most people when taken in amounts found in foods. Maca is POSSIBLY SAFE when taken by mouth in larger amounts as medicine, short-term. Doses up to 3 grams daily seem to be safe when taken for up to 4 months.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking maca if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Extracts from maca might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, do not use these extracts.

Dosing

Dosing

The appropriate dose of maca depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for maca (in children/in adults). Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
