MACA, also known as Lepidium meyenii is a plant in the Brassicaceae family. The root of the plant is dried, powdered, and used to make supplements which are often used for fatigue reduction and libido support.
MACA is especially interesting as a libido support supplement in that unlike most other supplements that can improve libido MACA does not do so through hormonal changes and does not increase testosterone making it one of the safest libido supplements.
