Zinc Gluconate vs. Zinc Glycinate: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 22, 2023
Zinc Gluconate is a zinc salt of gluconic acid used in dietary supplements. Zinc Glycinate is a chelated form of zinc bound to glycine, used for better absorption.

Key Differences

Zinc gluconate is a nutritional supplement that provides the mineral zinc in the form of gluconic acid salt. It is commonly used to prevent zinc deficiency and to support immune system health. Zinc glycinate, on the other hand, is a form of zinc where the mineral is chelated, or bound, to glycine, an amino acid, which is thought to enhance its absorption in the body.
Zinc gluconate is known for its relatively good bioavailability and is widely used in over-the-counter supplements and cold remedies. Zinc glycinate is often preferred for its higher bioavailability and is believed to be gentler on the stomach, making it a suitable option for those with sensitive digestive systems.
The chemical composition of zinc gluconate means it dissociates into zinc and gluconate in the stomach, which can influence its absorption rate. Zinc glycinate’s chelated form allows it to pass more easily through the intestinal wall, potentially resulting in better zinc uptake by the body.
In terms of application, zinc gluconate is commonly found in lozenges for cold relief as well as in general supplements. Zinc glycinate, due to its enhanced absorption and gentle nature, is often used in specialized supplements aimed at maximizing zinc intake without gastrointestinal discomfort.
Both forms are effective in providing the body with zinc, the choice between zinc gluconate and zinc glycinate may depend on individual factors like digestive sensitivity and specific health goals, as well as the desired form of the supplement.
