Compare L-theanine supplements by the full label
Start with the amount per serving. Our label lists 50 mg green tea L-theanine per one-strip serving. Compare that with the serving on another product, including how many capsules, gummies or scoops make up that serving. A number on the front of a bottle may describe more than one unit.
Choose between a single ingredient and a combination. Cognitive Relax is a combination formula. Each strip also contains 25 mg gamma-aminobutyric acid (GABA) and 6 mg vitamin B6 as pyridoxine hydrochloride. If you want only L-theanine as the featured ingredient, a single-ingredient formula is a different shopping choice.
Keep the whole-strip weight separate. The serving size is one oral strip weighing 290 mg. That is the weight of the entire strip, including its other ingredients; it is not 290 mg of L-theanine.
Check the exact formula name. L-theanine can appear in different types of blends. The presence of L-theanine does not mean two formulas have the same other ingredients, directions or purpose. Read the complete panel before comparing.
Oral strips vs capsules, gummies and powders
The main practical difference is the routine. HerbaGrove Cognitive Relax Strips dissolve on your tongue before swallowing. Capsules, gummies and powders have their own directions and ingredient lists. Choose the strip format when its flavor, packaging and one-strip serving fit your preferences.
Do not use the format alone to judge absorption or expected results. A small strip does not establish a faster effect, and an equal amount of one ingredient does not make two multi-ingredient formulas equivalent. Compare the full labels and follow the directions for the specific product you buy.
Ingredients and flavor
The other ingredients are pullulan, mannitol, cellulose, strawberry flavor, lecithin, malic acid, monk fruit extract, pectin, erythritol, peppermint flavor and steviol glycosides. The listed flavor is strawberry-peppermint. HerbaGrove makes the complete ingredient list easy to review, so you can choose by your taste and ingredient preferences.
Melatonin is not listed in Cognitive Relax Strips. For a separate comparison of bedtime formulas, see our sleep supplement guide. For other dissolving formulas, see our oral supplement strips guide, which compares iron, D3/K2, energy and L-theanine/GABA options.
