Natural Factors Natural Factors - Magnesium Bisglycinate Plus L-Theanine - 250 mg 250 mg, 90 vcaps
Natural Factors Magnesium Bisglycinate Plus L-Theanine - Combines 40 mg of the essential mineral magnesium with 250 mg of the amino acid L-theanine to temporarily promote relaxation without causing drowsiness. This non-GMO formula features magnesium bisglycinate, which is easy on the stomach and does not rely on stomach acid for absorption. Magnesium is an essential mineral required as an enzyme cofactor in more than 300 metabolic reactions throughout the body. It helps maintain healthy bones, teeth, muscles, and nerves and is needed to metabolize nutrients into energy. L-theanine is found naturally in green tea and has long been known to promote a sense of calm in tea drinkers. It provides a noticeable effect within 30–40 minutes of supplementation, helping to relieve symptoms of occasional and daily stress, calm the nerves, and focus the mind.
