Theanine

Theanine or L-theanine is an amino acid found in green tea that stimulates the alpha brain waves. Therefore, it has important calming properties.

Moreover, theanine is involved in the formation of gamma-aminobutyric acid, an inhibiting neurotransmitter. This substance is known as GABA, and it affects another two neurotransmitters, dopamine and serotonin. All in all, it produces a relaxing effect on the body.

You can also get it from supplementation, providing support for stressful situations.

Where can I buy theanine supplements?

In HSN, you can find l-theanine in vegetable capsules that will provide 250mg of this amino acid. You can also buy smart caffeine, a product by HSNessentials that will provide 100mg of caffeine and 250mg of l-theanine.
