L-theanine 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 primary neurotransmitters— serotonin, GABA and dopamine— while promoting the alpha brain waves responsible for a simultaneous feeling of alertness and relaxation. 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, a better sleep and a better mood.

Whether you’re medicated or not, l-theanine has an excellent safety profile for children and adults alike. Especially indicated for those with a ‘busy brain’, it calms racing thoughts. When taken at bedtime, l-theanine may reduce incidence of early wake-ups. Best of all, l-theanine is may be taken at any time and is safe to use preventatively, so there’s no need to reserve it for the onset of a stressful occasion.
