L-theanine is a unique non-protein amino acid in tea, which was discovered by a Japanese scholar in 1950. It can be automatically converted into GABA in the human body, making people feel better and more focused, and relieving tension and anxiety.
In addition to relieving anxiety, L-theanine synthetic and fermented also has a good sleep aid effect, similar to GABA and melatonin, so which of the three is better and safer?
In terms of safety, theanine and GABA are better, and melatonin is sold as a prescription drug in the United Kingdom, Japan, Australia, and other regions, and cannot be purchased casually.
In terms of effect, the effect of melatonin is obvious, but it is not suitable for long-term use. The effect of GABA and L-theanine is not as fast as melatonin, and there will be no immediate effect after eating. But L-theanine supplement is a naturally occurring ingredient in tea with clear principles and safety and is a mild dietary supplement.
