NOW Foods L-Theanine 200 mg Double Strength 120 Veg Caps | Amino Acid Supplement
NOW Foods L-Theanine 200 mg Double Strength 120 Veg Caps | Amino Acid Supplement
NOW Foods L-Theanine Double Strength delivers 200 mg of L-theanine in a single vegetarian capsule, with 100 mg of inositol, in a 120-capsule bottle.
L-theanine is an amino acid found naturally in the leaves of the tea plant (Camellia sinensis). This is the double-strength format from NOW Foods, providing 200 mg per capsule compared with the standard 100 mg format, so one capsule covers a full serving. It is a single-active amino acid product: L-theanine is the main ingredient, alongside 100 mg of inositol, and nothing else is added. The capsule is a vegetarian hypromellose shell, suitable for vegans.
