Dimethylethanolamine (DMAE) is a naturally occurring substance found in small amounts in eggs. It can also be produced synthetically and used in a variety of products, including cosmetics, pharmaceuticals and industrial chemicals.

DMAE is a quaternary ammonium compound whose nitrogen atom is positively charged. This charge allows it to bind to negatively charged molecules, such as proteins and DNA. In eggs, DMAE is found in the egg white and yolk. It is thought to play a role in embryonic development and eggshell formation.

DMAE is also thought to have some health benefits. It is sometimes used as a dietary supplement to improve cognitive function, memory, and mood. It is also used to treat hair loss and improve skin elasticity.

However, there is limited scientific evidence to support these claims. More research is needed to determine the safety and effectiveness of DMAE.

If you are considering taking DMAE, be sure to consult your doctor first. DMAE may interact with certain medications and is not safe for everyone to take.
