Improve learning and memory

There is some evidence that maca can help with learning and memory. A 2011 study, for example, discovered that maca could boost memory in mice. According to a 2014 assessment of the literature, maca may have benefits for learning and memory performance. It may be useful in treating disorders that disrupt these processes, such as Alzheimer's dementia, according to the researchers.

However, because only animal models have been studied, it is unknown whether maca will have the same benefits in humans. An older study in an animal model found that maca might help protect the skin from UV rays. Another animal study in 2011 found that extracts from maca leaves might help prevent the formation of sunburn cells.
