Histidine is an Essential Amino Acid (so is not produced by the body). It is used by the body to produce certain enzymes such as gastrin, which assists digestive processes, potentially leading to more vitamins and minerals being absorbed.
Histidine assists the bodies' balance of minerals and vitamins, so those whose diets are low on histidine are often deficient in zinc and other minerals, which can lead to weaker immune systems.
Dosage
A typical dose of L Histidine is between 1000mg and 2000mg per day.
