What is L-Theanine? L-Theanine is an amino acid primarily found in tea leaves, particularly green tea. It is known for its potential calming and neuroprotective properties.

What does it do when consumed? Upon consumption, L-Theanine can cross the blood-brain barrier and positively influence brain function. It has been linked to an increase in alpha brain waves, which are associated with a state of "wakeful relaxation" - alertness combined with relaxation and mental clarity. This improves attention, focus, and cognitive performance. L-Theanine may also exert anti-anxiety effects by modulating certain neurotransmitters and reducing physiological responses to stress.

L-Theanine Capsules: Each vegetable based capsule provides an effective dose of 200mg of the highest quality L-Theanine.

With its origins in nature, L-Theanine has gained popularity due to its ability to promote a sense of relaxation and mental clarity, making it a sought-after supplement for those seeking a natural way to manage stress, enhance cognitive function, and achieve a state of balanced energy.
