CanPrev L-Theanine Details

L-Theanine provides an impressive 250 mg of pure L-theanine along with 20 mg of magnesium bisglycinate to promote a state of relaxation and reduced anxiety without sedation, so that you can stay focused and productive.

Ingredient Description

L-Theanine is a non-protein amino acid that occurs naturally in the green tea plant. Studies show that L-theanine induces alpha brainwave activity, which correlates with a perceived state of relaxation. A small Japanese study of university students demonstrated that oral administration of 200 mg of L-theanine led to increased alpha brainwaves and a subjective sense of relaxation. Theanine administration caused a dose-dependent, relaxed yet alert state of mind without sedation, beginning approximately 40 minutes after oral dosing.

Magnesium is a mineral that is especially important for muscle function. It acts with calcium to help regulate the body’s nerve and muscle tone, and helps to relax muscles and prevent spasms. Inadequate magnesium appears to reduce serotonin levels, which is why symptoms of magnesium deficiency can include anxiety and depression. A 2008 study found that magnesium was as effective as tricyclic antidepressants in treating depression among people with diabetes.
