It caters to busy professionals, students, or anyone facing high-pressure situations, providing a sense of calm without the sedation associated with other relaxants.

Ingredient Quality and Source
Not all L-theanine supplements are created equal. The Sports Research L-Theanine 200mg uses Suntheanine, a patented form that has been clinically studied for its ability to increase alpha brain waves, which are associated with a calm yet alert state. When choosing a product, look for brands that disclose the source of their theanine and avoid proprietary blends that hide ingredient amounts. This transparency ensures you get the full benefits of L theanine for relaxation without unnecessary additives.
Dosage and Potency
Effective dosages of L-theanine typically range from 100 mg to 200 mg per serving. The Sports Research formula provides 200 mg in a single softgel, which is a commonly recommended amount for promoting relaxation and reducing stress-related symptoms. If you are new to this amino acid, starting with a lower dose may be wise, but a 200 mg capsule offers flexibility for most users.
