Buying Guide: What to Look For in an L Theanine Supplement
Purity and Source of L Theanine
Not all L theanine is created equal. The gold standard is Suntheanine, a patented form that has been clinically studied for its ability to increase alpha brain waves. Brands like Sports Research use Suntheanine exclusively, which guarantees both potency and purity. If you prefer a plant based option, look for supplements derived from green tea extract without synthetic additives. For a deeper dive into how purity affects results, read our L theanine benefits for stress guide.
Dosage Strength and Flexibility
Most studies use 100 to 400 mg per day. A 200 mg dose works well for many people, but some need a higher amount for pronounced stress relief. NUTRAHARMONY offers 400 mg capsules, which can be split if needed. Nature Made provides 200 mg chewable tablets that dissolve quickly, making them ideal for on the go use. Choose a dosage that matches your sensitivity and desired effect.

L theanine comes in capsules, softgels, chewables, and powders. Softgels like those from Sports Research are easy to swallow and often contain coconut oil for better absorption.
