  • Helps in relaxation.
  • Enhances ability to learn.
  • Offers pleasurable sensations.

Theanine 100 is made up of the amino acid Theanine, which is found mainly in green tea. It exhibits a beneficial effect in brain metabolism. Theanine helps the body to relax without inducing drowsiness, as determined by brain-wave testing that has observed an increase in the generation of alpha-waves. Reduced stress levels is a benefit of theanine’s ability to relax the body.

The blood pressure regulation is partly dependent upon certain neurons in both the brain and nervous system. Studies have shown that theanine may help lower blood pressure. Theanine affects dopamine and serotonin levels and thus may help in enhancing learning ability and cause pleasurable sensations.

Some studies demonstrate that theanine may increase the effectiveness some of the agents used in chemotherapy. Additionally, theanine may also decrease chemotherapy’s oxidative damage on normal cells.

Suggested Use: Take 1 to 2 capsules per day with water or juice on an empty stomach, or as directed by your qualified health care consultant.
