The verdict
Clinical dose, proven form.
For general wellness buyers.

L-Theanine at exactly the 200mg optimal dose. This is the gold standard for calm focus and stress relief. Inositol at 100mg is a minor support addition (well below clinical dose for anxiety) but adds marginal value. Clean formula that nails its primary purpose.

The read

NOW Foods NOW L-Theanine 200mg: the formulation holds up. Lead: L-Theanine at 200 mg. L-Theanine at exactly the 200mg optimal dose. Clinical dose on the primary, and the panel holds together.

A focused dose of L-theanine designed to promote relaxation and calm without causing drowsiness.. The 200mg dose of L-theanine is right where it needs to be for real results. While the inositol is mostly window dressing at this low amount, it doesn't take away from the product's value. It's a clean formula from a brand that usually gets the basics right.
