DMAE

DMAE (dimethylaminoethanol) is a compound related to choline, a nutrient the body uses to build the messenger chemical acetylcholine, which nerve cells rely on for memory and learning. People mostly look at it for cognitive decline, and a single trial of 241 people with suspected early Alzheimer's disease found no clear difference after six months. The evidence is very limited, since that one study tested a particular DMAE-based formulation, so it says little about DMAE on its own.
