A member asked:
Any interaction between 200 mg of l-theanine and bystolic? i take 2.5 mg bystolic and 100 mg l-theanine, with no issues. would 200 mg be too much?
A doctor has provided 1 answer
GRAS up to 250 mg: 1st, L-Theanine (a glutamine derivative found in tea & fungi) is classified as GRAS- Generally Regarded As Safe- by the FDA. Doses up to 1200 mg have shown little, if any positive OR negative effect. In fact, there is no clear proof that L-Theanine has any health benefits, & some negative data that it does nothing to improve mood. Proteins rarely interact with drugs. You may be wasting your money!
