    L-Theanine Benefits

    L-Theanine improves cognitive and mental processing. It is useful in bringing brain waves back to normal levels after strenuous exercise to promote mental recovery.

    This supplement can promote healthy blood pressure levels by keeping the body in a state of relaxation.

    L-Theanine can strengthen immune system function

    L-Theanine and Sleep

    L-Theanine promotes both relaxation and improves sleeping patterns [1].

    L-Theanine induces sleep by promoting the production of GABA, which calms neurons and receptors [5]. When the brain is calm, you fall asleep faster and enjoy more restful sleep. L-Theanine crosses the blood-brain barrier, so you can enjoy the sleep benefits of the supplement quicker[5].

    L-Theanine and Caffeine

    You might also want to consider stacking L-Theanine with your Caffeine supplement to promote a smoother stimulation level [4]. One of the many L-Theanine benefits is that it helps to eliminate the jittery, wired sensations that often come with Caffeine supplementation, while improving the cognitive benefits of Caffeine too [4, 5]. For this reason, L-Theanine and Caffeine have become a popular nootropic stack.

    Experience the benefits of theanine and caffeine by trying these capsules.

    L-Theanine Side Effects

    L-Theanine is safe when taken as recommended. Although uncommon, possible side effects include headache, irritability, diarrhea, and heartburn, particularly when paired with caffeine.

    L-Theanine Dosage

    It is recommended to take two 0.15cc scoops (100mg) up to twice daily.
