l theanine stress

L-theanine stress supplements commonly come as powders, capsules, gummies or chewables, and transdermal patches.

Dosages vary across listings, ranging from single-digit milligrams up to about 200 mg per serving. Many products show common serving sizes of 100 mg or 200 mg.

Most listings emphasize a calm, relaxed state without sedation, describing "relaxed alertness" or reduced stress while noting the formulas are designed to avoid drowsiness.

The listings describe effects such as relaxation or reduced tension, support for focus or mental alertness, stress or cortisol management, and in some cases improved sleep quality; several specifically note producing calm or relaxed alertness without drowsiness.

Age recommendations vary across listings—examples include "All Ages," "Adult," "18 Years and Up," and "12 Years and Up." Common warnings include "Adult Use Only," pregnancy cautions such as "Do not use if you are pregnant," and standard directions to keep products out of reach of children.

A non-oral format shown in the listings is a transdermal patch designed to deliver calming ingredients through the skin, with instructions to apply the patch to clean, dry skin.

Some chewable or chewable-style formulas report an onset of about 30–60 minutes. A transdermal patch listing notes effects may begin in around 20 minutes and last up to about 12 hours.
