Zinc Glycinate, also known as Zinc Bisglycinate

Zinc Glycinate, also known as Zinc Bisglycinate, is a highly bioavailable form of zinc that is chelated to glycine, an amino acid. This unique molecular structure enhances its absorption and utilization in the body, making it superior to other forms of zinc supplements.

Chemical Properties Zinc Glycinate is a white crystalline powder that is slightly soluble in water. It has a molecular formula of C4H8N2O4Zn and a molecular weight of approximately 213.5 g/mol. The compound is characterized by a zinc ion coordinated to two glycine molecules through coordinate covalent bonds, forming a stable chelate complex (Zn(H2NCH2COO)2).

Bioavailability and Absorption One of the key advantages of Zinc Glycinate is its enhanced bioavailability. Unlike other zinc salts, which can be ionized in the gut before absorption, Zinc Glycinate remains intact as a chelate and is absorbed directly into the bloodstream. This not only increases its absorption rate but also reduces the likelihood of digestive disturbances commonly associated with other zinc supplements. Studies have shown that Zinc Glycinate has superior bioavailability compared to zinc gluconate and other inorganic zinc salts.

Health Benefits Zinc is an essential mineral involved in over 300 enzymatic reactions in the body. It plays a critical role in immune function, skin health, and cognitive function. Zinc Glycinate, due to its high bioavailability, can provide the following health benefits:

Immune Support: Zinc is crucial for the proper functioning of the immune system. It helps in the development and activity of immune cells, thereby supporting the body's defense against infections.

Skin Health: Adequate zinc intake is associated with improved skin health. It can help manage acne and promote wound healing.

Cognitive Function: Zinc is involved in neurotransmitter function and can support cognitive health.

Hormonal Balance: Zinc plays a role in inhibiting the conversion of testosterone into dihydrotestosterone (DHT), which is implicated in various health conditions. Maintaining optimal zinc levels is crucial for fertility and hormonal balance.

Applications Zinc Glycinate is widely used in various industries due to its unique properties:

Dietary Supplements: It is commonly used as a dietary supplement to maintain healthy zinc levels in the body.

Food Fortification: It can be added to dairy products, solid drinks, cereal health products, and other food items to enhance their nutritional value.

Pharmaceutical Formulations: Its water solubility and stability make it adaptable to various pharmaceutical formulations, accommodating diverse delivery methods.

Preparation and Stability The preparation of Zinc Glycinate involves chelating glycine with basic zinc carbonate in a reaction kettle, followed by drying to obtain the final product. This chelated form exhibits enhanced stability, safeguarding the zinc ion from degradation during storage and handling, ensuring product consistency and potency.

Dosage The recommended dosage of Zinc Glycinate varies depending on the application:

Milk Powder: 30-60 mg/kg

Rice, Wheat Flour and Products: 10-40 mg/kg

Soy Flour, Soy Milk Powder: 29-55.5 mg/kg

Solid Drinks: 60-180 mg/kg

Western-Style Pastries, Biscuits: 45-80 mg/kg

Conclusion Zinc Glycinate is a highly effective and versatile form of zinc supplementation. Its superior bioavailability, gentle nature on the gastrointestinal tract, and excellent stability make it a preferred choice for maintaining optimal zinc levels in the body. Whether used in dietary supplements, food fortification, or pharmaceutical formulations, Zinc Glycinate offers significant health benefits and is an essential component for overall well-being.
