How Does It Work?

As a plant, maca contains many different compounds and nutrients. It contains carbohydrates, proteins, fiber, and fatty acids. It contains a few different plant sterols and polyunsaturated fatty acids, which may be responsible for many of the medicinal properties. It also contains a significant amount of minerals, such as calcium, iron, and copper. Maca also contains compounds known as glucosinolates, which may have anti-cancer properties.
It is not clear how exactly maca works for any use, although it has been shown that the substance does not seem to affect testosterone, estrogen, or other similar hormones, at least in healthy men.

Is Maca Effective?
