FAQ:

Q: Can You overdose on L theanine?

A: There have been no reports of overdose or side effects of taking l theanine and drinking tea is generally safe for most people. By stimulating the production of more gaba as well as other important neurochemicals such as dopamine serotonin and norepinephrine l theanine steers the mind to naturally reduce anxious feelings and stress.

Q: Does L theanine work immediately?

A: The first thing I recommend you do if you want to make l theanine work faster is to take it on an empty stomach. Since the supplement has to travel through your stomach in order to be absorbed, it of course helps to not have anything in there. Now, this may not be the most practical tip if you want to take theanine for sudden anxiety attacks.

Q: What are the dangers of theanine?

A: – nausea – upset stomach – irritability

Q: Can L-theanine be taken with alcohol?

A: L-Theanine consumed after a night out drinking can effectively decrease brain fog and help you be at your best the following day. People sometimes mix L-theanine with alcohol so as to minimize the effects of hangover the next day. L-Theanine also helps to reduce alcohol levels inside your body, which makes it harder for you to get drunk.
