What is L-theanine?
L-theanine is an amino acid derived from tea and known primarily for its calming effects. Thought to stimulate alpha wave production in the brain, it has long been popular in Japan and has emerged as a popular supplement in the American market for use in reducing stress and anxiety.

What are the health benefits of L-theanine?
L-theanine is noted for its capacity to induce relaxation without any sedating effects. Studies have also shown that it can improve mental clarity and the ability to concentrate. L-theanine increases levels of the neurotransmitter dopamine, which can have a positive influence on mood and cognitive function.

When taken in combination with coffee, L-theanine may reduce the nervousness caused by caffeine without inhibiting caffeine’s stimulating properties. L-theanine is also considered helpful in alleviating symptoms of PMS and boosting the immune system. In addition to its use in supplementation, L-theanine has also been marketed as an ingredient in some energy drinks, touted for its ability to improve focus.

Where can I find L-theanine?
L-theanine can be consumed by drinking tea although it’s been suggested that tea does not contain a sufficient amount to be beneficial. L-theanine supplements can be found online, in health food stores, and in the offices of alternative medical practitioners.
