Deanol, also called DMAE (dimethylaminoethanol), is a small organic compound related to choline that occurs in trace amounts in some fish and is also made synthetically for supplements.
Why it’s used
Marketed for cognitive support and sometimes for skin appearance, on the theory that it may act as a precursor to choline or acetylcholine.
What the evidence says
Human clinical evidence is sparse and mostly old or small. Claims about cognition or mood are not well supported by rigorous trials, and its conversion to acetylcholine in the body is not firmly established.
