What is L-Theanine?

L-Theanine is an amino acid primarily found in certain plants and fungi. It is known for its calming effects on the mind and body, making it a popular choice for individuals looking to manage stress and improve focus. L-Theanine works by increasing the production of alpha brain waves, which are associated with a state of relaxation and mental alertness.

Drinking green tea can help promote a sense of tranquility and mental clarity. To incorporate green tea into your daily routine, you can enjoy it as a warm beverage in the morning or as an iced tea throughout the day. Adding a slice of lemon or a sprig of mint can enhance the flavor and provide additional health benefits.
