The more ENADA Co-E1 that is introduced into brain tissue, the greater the increase (+25%)The more NADH the brain has the more brain activity ocurrs in measured electrical brain activity.  This electrical brain activity increases are in the areas of the brain used for thinking, focusing, mental clarity, memory recall, concentration, cognition, attention, co-ordination, etc. These studies also show that a ENADA Co-E1 ( NADH) supplement (i.e., NADH that is given orally) will increases the levels of Co-E1  found in brain tissue.

A summary of the clinical study abstract is listed below. The studies themselves are attached. Warning, the text of this subject is complicated for non-healthcare professionals.
