This naturally occuring amino alcohol is produced in minuscule amounts by the brain, with higher concentrations being typically found in anchovies and sardines. Known primarily as a precursor to choline and acetylcholine (chemicals in the brain responsible for nerve transmissions and cognitive function), DMAE has been used most predominantly to improve memory and focus while stimulating neural activity. Many researchers believe that it may serve an anti-aging function by increasing the body’s capacity to produce acetylcholine – a deficiency commonly associated with memory loss.
