What Is Theanine?

Theanine is an amino acid found in some plants including the basidiomycete mushroom and green tea. This nootropic is known to be a stress reliever and relaxant that also carries a number of nootropic properties. In 1964 theanine was approved by the Japanese Ministry of Health and Welfare for universal consumption. It is currently available in the United States as a dietary supplement and is confirmed by the FDA for being “Generally recognized as safe” [4]

Certain beverage manufacturers have begun to manufacture drinks containing thiamine and are currently marketing them as focus and concentration aids. [18] Other manufacturers are marketing them for their ability to help people relax. [14]

Theanine Dosage Information

Even though there is no standard dose for thiamine, many sources indicate a dose of 200-300mg should be taken as needed. Other people have found that they must take as much as 500mg at a time to notice an effect. I recommend you start with a 200mg dose and work your way up as needed.  It will take 30-60 minutes for the dose to take effect and may last from 3-4 hours.

Theanine is able to cross the blood-brain barrier. [3][6] Once it crosses this barrier it acts on the brain in a number of ways giving it many nootropic properties:
