3 Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

L-Theanine is a non-protein amino acid found naturally in the green tea plant (Camellia sinensis). It is an effective GABA precursor and supports healthy relaxation without drowsiness. Because it can cross the blood-brain barrier, L-theanine helps increase brain dopamine levels and helps support a normal immune system. *

L-Theanine 200 mg


Product Code: 00147         Capsules per Bottle: 120

Each size 1 vegetarian cellulose capsule contains:

L-Theanine (Suntheanine ®)

200 mg


Description: Pure L-Theanine (Suntheanine ®) is a non-protein amino acid found naturally in green tea.


Uses: L-Theanine supports healthy relaxation without drowsiness. L-Theanine has been studied for its potential ability to reduce stress, boost mood, improve cognition, and enhance immune response.


Able to cross blood-brain barrier, L-Theanine increases levels of GABA, serotonin, dopamine and glycine in various regions of the brain. It also increases BDNF (brain-dervived neurotrophic factor) and NGF (nerve growth factor), and thus may have neuroprotective ability. L-Theanine has been shown to promote alpha-wave activity in the brain, a sign of relaxation.


Studies have shown that L-Theanine regulates the secretion of immune cytokines, thus enhancing innate immune function. A L-Theanine metabolite, ethylamine, also supports immune function by priming gamma-delta T cells, the first line of defense against many types of infection. L-Theanine may also have hepatoprotective qualities.


Source Materials: L-Theanine is derived from L-Glutamine via an enzymatic process. Cellulose for capsules is derived from softwood tree pulp. All ingredients are vegan and non-GMO.


Allergens: According to information provided by our suppliers, these capsules are free of the eight major allergens as identified by the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA): Wheat (gluten), eggs, milk, soybeans, shellfish, fish, peanuts, tree nuts.


Recommendations: One (1) capsule daily, or as directed by a healthcare professional. Best taken between meals.


Precautions: Pregnant or lactating women and individuals taking prescription medications should consult with a healthcare professional before taking any supplement.
