MTS Nutrition L-Theanine 200mg Capsules

L-theanine is an amino acid found in green tea, which is a rich source of polyphenols that promote overall health and feature antioxidant properties. L-theanine also assists with relaxation and well-being, reduces stress, and helps maintain daytime alertness.

This wonder ingredient has been shown to help with mental focus and sleep quality, which is an unlikely combination! The reason is that L-Theanine may affect the levels of certain chemicals in the brain, like Seratonin and Dopamine, which help influence mood, sleep, emotion, and cortisol. These actions in the body are inevitably how your body deals with environmental stress.

L-Theanine may also help reduce appetite, support healthy weight management, boost the immune system, and reduce blood pressure.

Solid Product

I’ve now been taking this product for a couple weeks. I notice clarity and mental focus, and not distracted by stress. Overall I’d recommend. I’m 6’1” 275lbs. I notice full relaxation and positive mood.
