Dimethylaminoethanol, also known as DMAE or deanol, is a naturally occurring compound that can be found in foods such as anchovies and sardines. DMAE is a precursor to choline and acetylcholine, which are chemicals in the nervous system responsible for neurotransmission, muscle contraction, and cognition.* DMAE may be more bioavailable to the central nervous system than choline. Supplementation with DMAE supports healthy mood and emotional well-being.* It may also promote optimal memory and the improved ability to maintain focus.* DMAE supplies DMAE as the salt, bitartrate.
