What is it?

Maca is a plant related to the cabbage family. It is used as food and medicine in Peru.

Maca supplements come as capsules, tablets, and powders.

What are the potential uses and benefits?

Maca is used to:

  • Improve your energy and strength.
  • Increase fertility (the ability to become pregnant with a biological child).
  • Improve your desire to have sex.
  • Relieve side effects of your period stopping permanently, such as hot flashes.

Maca has other uses but doctors have not studied them to see if they work.

Talk with your healthcare providers before taking maca supplements. Herbal supplements are stronger than the herbs you would use in cooking. Some herbal supplements can also affect how medications work. For more information, read the “What else do I need to know?” section below.
