Integrative Therapeutics’ L-Theanine 100 mg provides a powerful boost of Theanine‚ a natural substance found in Japanese green tea. Integrative Therapeutics’ supplement features the L-isomer of the extremely beneficial amino acid‚ which is linked to the amino acid known as glutamate.

What makes L-Theanine so valuable?

L-Theanine is an amino acid that has shown the valuable ability to offer support for the regions of the brain responsible with controlling your moods. Specifically‚ electroencephalographs (EEG machines) have indicated theanine’s positive impact on the brain’s alpha-wave activity.

How can L-Theanine help you?

This substance may promote a state of relaxation while reducing feelings of anxiety and stress. It lessens the detrimental effects of caffeine‚ and can relieve symptoms associated with premenstrual syndrome (PMS) in women. However‚ the great potential benefits of L-Theanine don’t stop there: it can boost the strength of your immune system to prevent illnesses‚ while also supporting memory and cardiovascular health.

Research has proven the health benefits of L-Theanine

L-Theanine has been the subject of research for more than six decades‚ and is often utilized for its mood-liftingabilities in Japan. Products intended to supplement production of this amino acid continue to appear on the market‚ as recognition of L-Theanine’s benefits increases. That certainly makes L-Theanine 100 mg worth trying‚ especially since the capsules are suitable for vegetarians. Each dosage provides 100 mg worth of pure theanine. One bottle contains 60 ultra capsules.

Integrative Therapeutics has been providing high-quality nutritional supplements to health care professionals for over 35 years. Its products have been tested in thousands of clinical studies‚ and are proudly manufactured in a GMP-audited facility. The manufacturing processes of Integrative Therapeutics meet or exceed all industry standards.

      Taking at least 200mg/day of this L-Theanine has helped reduce fatigue and brain fog I have due to CFS. This is a miracle for me and allows me to feel much more normal without the constant fatigue, brain fog and post exercise malaise I have had continuously for years.

      This is my second review. I recently had an old tattoo re-inked and I took 2 L-theanine and one GABA (also purchased from this site) and I fell asleep during the process. I will do this again when I go to the dentist or if I am having a minor medical issue cared for. I have L-theanine in our medicine cupboard at all times now. It helps with anxiety and it relaxes. My doctor said I could take an extra one in times of high stress or if I wake up during the night

      Pros

      It is less expensive than some of the other brands and just as effective.

      Cons

      My doctor recommended I take this for anxiety during a time of high stress. They helped me sleep. Now that I am feeling better due to several factors, I take L-Theanine when I fly or travel for restful sleep. I also take it occasionally when I am going to be in a high-stress situation. This is not the brand I originally tried, both work the same and this is less expensive.

      Pros

      It helps with relaxation during stress

      I’m usually a good sleeper but there are times when my body just refuses to get a good night’s sleep. Integrating the L-theanine into my routine before bedtime gets me back into deep sleep and feeling fully rested in the morning.
