Our Verdict
Its 200 mg dose, vegan capsule, low price, and roughly 5,000 iHerb reviews make it the strongest remaining generic capsule. Weak testing documentation and undisclosed L-isomer process keep it behind the other selections.

Alternatives to Consider
California Gold Nutrition, L-Theanine, Featuring AlphaWave, 100 mg, 60 Veggie Capsules
California Gold Nutrition
Each vegan capsule supplies 100 mg of branded AlphaWave L-theanine without caffeine. A published iTested report identifies the product codes, laboratories, potency result, and microbial results, although it covers lot 3533 from 2018 rather than current inventory.
Natural Factors, Stress-Relax, Suntheanine L-Theanine, 100 mg, 60 Chewable Tablets
Natural Factors
The label defines one serving as two chewable tablets, providing 200 mg of enzymatically produced Suntheanine. The product is vegan and carries Isura non-GMO documentation and mass-spectrometry laboratory verification, but each serving also contains 3 g of added sugar.
Doctor's Best, L-Theanine, AlphaWave, 200 mg, 60 Veggie Caps
Doctor's Best
One vegan capsule supplies 200 mg of AlphaWave L-theanine with no caffeine. The label fully discloses the active dose and excipients, but the iHerb page does not link a recognized finished-product certification or product-specific certificate of analysis.
Nutricost, L-Theanine, Unflavored, 3.6 oz (100 g)
Nutricost
Each 0.2 g scoop contains 200 mg of generic L-theanine, and the label lists no other ingredients. It is by far the lowest-cost option per active milligram, although the page supplies only a general third-party-tested claim rather than a named certification or published COA.
