Pineal® Tens is a food supplement containing Magnesium bisglycinate, L-Tryptophan, Niacin, Vitamin B2 and Vitamina D3. One of the determining factors when taking a mineral salt supplement is the actual absorption at the intestinal level and the consequent bioavailability of the micronutrients. Chelation is, compared to the other saline forms, a technique that allows to maximize the absorption of salts such as Magnesium, making them usable for their physiological functions.
