DMAE (dimethylaminoethanol) is always present in small amounts in the brain. This substance is also found in foods such as sardines and anchovies, although only in smaller amounts. A sufficient amount of DMAE in the brain can have positive effects on its function. DMAE is called a “nootropic” substance. Nootropic substances are substances that aim to maintain optimal brain performance. These substances can promote the permeability and stress resistance of the cell membrane as well as influence the formation of serotonin. The mechanism of action is described as an increase in the concentration of the neurotransmitter acetylcholine in the brain.
The main functions of DMAE are to maintain optimal brain performance and brain function including learning ability, concentration and memory, as well as to support a positive state of mind. The latter is attributed to the positive influence of DMAE on the serotoninergic system, which can also lead to less daytime fatigue and better night sleep.
If the absorption of DMAE through the diet is not sufficient or there is an increased need, this nutrient can be supplemented through special food supplements.
