It was first identified and isolated as a major component of green tea in the late 1940's, and it was later found in other forms of tea as well. Theanine constitutes around 50% of the amino acids in tea and makes up 1-2% of the dry weight of tea on average, although one source indicates that the number is closer to 1.5-3%. This places the content in a normal cup of tea in the 20-60 mg range. Benefit:

Stroke prevention/treatment Suggested Use:
After oral administration, theanine is absorbed in the intestine and then easily crosses into the brain from the bloodstream through an amino acid transporter [11, 15]. The increase in alpha wave activity in the brain is measurable within 30 minutes and maximized at the 40 minute point. Although the pharmacokinetic profile in humans is not well-known, in rats, it is metabolized in the kidney to L-glutamate and ethylamine and is completely absent 24 hours after administration. No toxic effects of theanine have been reported, and green tea has a long history of safe use. Toxicology studies have failed to find any side effects or toxic effects associated with theanine, even in large amounts.
