Acetyl-L-Carnitine supports mitochondrial energy production and enhances the production neurotransmitter acetylcholine.  Research shows Acetyl L-Carnitine has the ability to enhance brain function and exert an antidepressant effect.

 

Sam-e has been extensively studied for its antidepressant activity.  It works as a methyl donor involved in the synthesis of several neurotransmitters.  Its exact mechanism of action isn’t entirely clear, although it is suggested that Sam-e may normalize levels of specific neurons in the brain.

 

Another interesting compound is L-Theanine.  L-Theanine is a free form amino acid found almost exclusively in tea plants.  Studies suggest it can increase brain levels of serotonin, dopamine and GABA.  Clinical studies suggest L-Theanine may increase alpha wave activity, relaxing and focusing the brain without drowsiness.
