L-theanine deserves a gold star

L-Theanine is a unique non-protein amino acid found primarily in tea leaves especially green, black, and white (oolong) teas, L-theanine is a staple in my supplement routine—and for good reason.

It’s known for promoting a calm, alert state—helping to reduce overwhelm so you can stay focused, and quieting the mind when it’s time to wind down. It starts working quickly, with effects often felt within 30 minutes.

It helps regulate the brain’s resting state by lowering cortisol levels and promoting a calm, relaxed, yet mentally alert mood. In other words, it helps you feel steady and focused without feeling drowsy.

L-Theanine shows strong potential for supporting individuals with high morning cortisol, anxiety, stress, and sleep disturbances—alongside a range of other benefits.

One of its key benefits is increasing the release of GABA—our calming neurotransmitter—and enhancing how well GABA binds to its receptors. This may explain why L-theanine is so effective for easing anxiety and supporting better sleep.

Whether you're an anxious girly, prepping for an exam or job interview, need some sleep support, or need to smash out some work for a deadline, L-theanine has your back.
