Everyone is abuzz about L-theanine since Taylor Swift noted in the Elle magazine feature “30 Things I Learned Before Turning 30” that she loves the way the supplement soothes her stress and anxiety. “[They] make me feel so much better,” she says of her new plant medicine regimen.

So, how can L-theanine help you fall asleep easily, calm you down, and improve your energy? L-theanine is an amino acid that occurs naturally in black and green tea and certain mushrooms. While it may sound contradictory at first, a growing body of research indicates that L-theanine boosts overall mental performance. By soothing brain jitters, it can help you relax into a deep sleep or find renewed focus and attention to get important tasks done well.

Research published in 2014 looked at the impact of a combination of caffeine and L-theanine on testing anxiety and exam performance. “The drug was quite effective,” researchers wrote, “in reducing subjective and physical stress resulting from mental tasks.” Combining caffeine with L-theanine helps negate caffeine jitters as well, so the two make a powerful pair for energy boosting.

We’ve been enchanted with this natural wonder drug and plant-based relaxation for years now—L-theanine is an essential part of 1906 Go, 1906 Chill, and 1906 Bliss, along with our carefully selected strains of clean green cannabis. If you’re looking for a powerhouse plant medicine that works equally well as an alternative to Xanax or triple shots of espresso, make like T-Swift and give L-theanine a try.
