L-Theanine  is an amino acid found in green tea.

L-Theanine creates a feeling of relaxation. According to a research on human volunteers, this effect is achieved 30-40 minutes after taking L-Theanine supplements.

By increasing the levels of dopamine, L-Theanine may relieve symptoms of depression. Depression is a response to low levels of neurotransmitters like dopamine.

As it regulates serotonin levels, L-Theanine improves cognitive abilities like learning and memory. It also enhances attentiveness and focus.

The effect of L-Theanine on serotonin levels also helps alleviate anxiety and stress. It will greatly help you to perform all your daily tasks without being so stressed out. Taking 50-200 g of L-Theanine everyday is a great help in stress management.

L-Theanine is also suggested to boost the immune system, just like other multivitamins. Stress is a major factor contributing to an immune-compromised status. Taking L-Theanine capsules will strengthen the body’s defense against common infections.

By lowering norephineprine levels, L-Theanine is a potential anti-hypertensive agent. Norephinephrine regulates the body’s blood pressure and when it increases, there is also a corresponding increase in the systolic and diastolic pressure in the arteries. L-Theanine supplements are also safer alternatives for sleeping pills. It doesn’t make  you sleep, but it gives you the feeling of tranquility and calmness so you can naturally go to sleep.
