The Superior Bioavailability of Zinc Glycinate: A Highly Absorbable Form that Minimizes Gastrointestinal Discomfort Compared to Traditional Inorganic Zinc Salts
Zinc Glycinate, also known as zinc bisglycinate, is quickly becoming the preferred form of zinc supplementation among health professionals due to its superior bioavailability and gentle nature on the digestive system. This form of the essential mineral is a chelate, meaning the zinc is bound to two molecules of the amino acid glycine. This specific chemical structure protects the zinc from antagonistic dietary factors, such as phytates, and prevents it from interfering with the absorption of other minerals in the gut, ensuring a much higher utilization rate by the body.
The chelating process is key because it allows the zinc to be absorbed via the amino acid transport channels, which are highly efficient and distinct from the mineral channels typically used by forms like zinc oxide or zinc sulfate. Studies show that…
