DMAE (deanol, or dimethylaminoethanol) is a small molecule related to choline. It has been taken by mouth for attention and memory and is added to anti-aging skin creams.
Also known as: deanol, dimethylaminoethanol, 2-dimethylaminoethanol.
A 1975 trial in children used 500 mg a day for 3 months (Lewis 1975). These are study protocols, not a recommendation.
DMAE is sold in products labeled as supplements and in skin creams. Its effects in people have not been well studied.
What studies show: in a 3-month 1975 trial in 74 children with learning and behavior problems, deanol 500 mg a day and methylphenidate both improved some test scores compared with placebo; the authors said how deanol works is unclear and called for more studies (Lewis 1975). A 2018 Cochrane review of cholinergic drugs, including deanol, for tardive dyskinesia found the trials too few and too small to judge (Tammenmaa-Aho 2018). On the skin, a DMAE cream increased skin moisture in volunteers over 8 weeks, but so did the same cream without DMAE, and skin firmness did not change (Tadini 2009).
Safety: the sources here do not describe safety in detail. The sources here do not describe drug interactions.
We could not find a single published half-life or time to peak for DMAE that applies to a supplement dose, so we do not list one.
