Repower Your Brain

Out of stock


Source Naturals Theanine Serene is touted as one one of the most exclusive amino acids necessary for optimal brain clarity. L-Theanine is a unique amino acid, considered a nootropic, found almost exclusively in green and black tea made from Camellia sinensis plant. Camellia sinensis is an evergreen shrub native to East Asia, the Indian Subcontinent, and Southeast Asia. Currently, it is cultivated across the world in tropical and subtropical regions.

Studies have shown that taking L-theanine affects the emission of alpha waves and the levels of dopamine and GABA in the brain. All three support focus, relaxation, improved memory, and improved learning.

Research indicates that L-theanine may also support gamma delta T cell production for enhanced immune response and may play a role in cancer cell prevention.

In addition, research suggests as L-theanine crosses the blood-brain barrier, it may support healthy neurotransmitter levels in the brain and inhibit the negative side effects of caffeine such as jitters, and nervousness.

Theanine Serene is perfect for people who find themselves jittery, nervous, stressed regularly, and who feel drained and unfocused throughout their daily routine. Regain control of your work, responsibilities, and life!

Suggested Use: 1 tablet, 1 to 2 times daily.
