Maca improves learning and memory in animals

No traditional descriptions have been found about effect of maca (Lepidium meyenii) on learning and memory. Though natives in the central Peruvian Andes attribute the use of maca with improved school performance.

Experimental studies have shown that black variety of maca has positive impact on learning and memory in animals. Black maca improved learning and memory in mice [1, 3] and in memory impaired in mice [2].

Three varieties have been studied (black, red, and yellow) and black maca was the only on showing significant biological effects [1]. Black maca (0.5 and 2.0 g/kg) decreased brain malondialdehyde (MDA) levels marker of oxidative stress and acetylcholinesterase (Ache) levels in ovariectomized mice whereas no differences were observed in monoamine oxidase (MAO) levels [3].

In summary, different evidences suggest that particularly black maca, improves learning and memory. It was suggested that the effect of Black Maca on learning and memory may be due to the presence of polyphenolic compounds[1]. Previous studies did not show any toxic effect during short and long-term administration.[4]
