Theanine 100 mg 60 Capsules from Jarrow Formulas® that may promote relaxation and may improve learning ability. Theanine is an amino acid that takes active part in neurological health. This component is exclusively present in green tea. Many people believe that Theanine may affect brain metabolism and may cause relaxation in the body without drowsiness.

There are some studies that are based entirely on Theanine research. The chemical structure of Theanine is very similar to the amino acid glutamate. Studies say that these amino acids may assist in transmitting nerve impulses to the brain better.

There are some private studies that say that theanine may play a role in improving reaction time‚ numeric working‚ memory and sentence accuracy. There are more studies that say that theanine may boost disease fighting ability of gamma T cells in the body.

Some other studies say that Theanine raises levels of brain serotonin‚ GABA and dopamine. These may be responsible in the improvement of memory related tasks and in learning.

      It’s for my dog

      from CT on 5/20/2020
      On the advice of a dog trainer, I started using this on my dog that has anxiety issues. It works, a very noticeable difference in his behavior. It relaxes him. This was done with approval from my vet.

      Good nights sleep

      from Brandon VT on 3/23/2020
      I love this product in that it helps to calm my brain at night so I sleep without having an overload of thoughts in my brain at night. The research says that it produces alpha waves that promotes relaxation with sedation.

      Pros

      Works effectively....start with lowest dosage first.

      Cons

      Nothing
