L-theanine is an amino acid that promotes relaxation without the sedating effects that many herbs and pharmaceuticals have. Discovered in 1949 as a natural component of green tea leaves, it balances our neurotransmitters serotonin, GABA and dopamine while promoting alpha brain waves - - the signature of a calm, focused mind. At the same time, l-theanine inhibits the effects of the stress hormones epinephrine and norepinephrine. The result is a calm, focused mind that is more resilient against stress, promoting a better sleep and a better mood.
L-theanine has an excellent safety profile. It’s compatible with prescription medications, and may be used at any time of day on an ongoing basis because it is non-stimulating, non-drowsy and non-habit-forming.
Make Pure Lab’s L-Theanine Chewables part of your day and discover the benefits of a calm, focused mind.
