L-Theanine
L-theanine supplements are commonly used to support relaxation, calm focus, stress management, sleep quality, and nervous system wellness. Naturally found in green tea, L-theanine is often chosen by customers looking for non-drowsy relaxation support during the day or calming support in the evening.
At Optimize Nutrition, our L-theanine products may include capsules, tablets, chewables, powders, liquids, and blended formulas that fit easily into daily wellness, focus, or sleep-support supplement routines.
