Swanson Suntheanine L-Theanine, 200mg – 60 vcaps

Swanson Ultra Suntheanine L-Theanine comes in a 60-capsule pot, with each vegetarian capsule delivering 200mg of Suntheanine — a patented, high-purity form of the amino acid L-theanine. Swanson has been producing nutritional supplements to rigorous quality standards since 1969, and this product reflects that long-standing commitment to ingredient integrity.

L-theanine is a naturally occurring amino acid most commonly associated with green tea. Suntheanine is produced through a proprietary fermentation process designed to yield a consistent, pure form of the compound. The capsules are suitable for those following a vegan diet and contain no animal-derived ingredients.

This format appeals to those who prefer a straightforward capsule over powders or drinks — athletes, professionals, and anyone who values knowing exactly what they’re taking each day. With 60 capsules per pack, each providing a precise 200mg dose of Suntheanine, it’s a well-specified supplement from a brand with a long track record in the industry.
