L-Theanine is a naturally occurring amino acid found in tea leaves that promotes calm, focused mental states without causing drowsiness. It works by increasing alpha brain wave activity and supporting neurotransmitters like GABA and serotonin—helping you stay relaxed yet alert.

Often used to reduce acute stress, improve focus, and support the transition into restful sleep, L-Theanine is a safe, non-sedating option for managing mental performance and emotional balance throughout the day.

    Help, i can't fall asleep at night! Oh wait, now i can with L-Theanine

    I've been struggling with sleep for a couple of years through peri-menopause and now menopause. It could take me hours most nights to fall asleep at night. I have tried everything from limiting screen time and caffeine, taking a magnesium supplement, over the counter and prescription strength sleep aids and my favorite from a health coach was eat turkey before bed for the sleepy properties of tryptophan. None of these inherently helped me fall asleep. Within a week of using L-Theanine I was falling asleep faster than I have for a couple of years. I'm a fan!

    Zonkarrific

    This stuff works, simple as that. I take one at bedtime, within minutes, zonked out for hours. Don't know how or why, or whether having a mug of tea would do the same. I have no trouble getting to sleep in general, but this assures a quick and effective zonk.
