Request a SampleZinc bisglycinate is zinc bound to two glycine molecules. The chelated form is absorbed more efficiently than inorganic zinc salts (sulfate, oxide) because the intact chelate bypasses the competitive mineral transport pathways that limit inorganic zinc uptake. Published pharmacokinetic studies show 43% higher bioavailability than zinc gluconate.
The taste advantage matters for formulation. Inorganic zinc has a pronounced metallic aftertaste that limits application in flavored products. Zinc bisglycinate is organoleptically neutral. It does not contribute metallic or astringent notes, making it compatible with a wider range of finished formats.
Elemental zinc content varies by form: the 25% glycinate form has a higher elemental zinc percentage per gram; the 10% bisglycinate form is more fully chelated. Lower elemental percentage means a more complete chelation reaction, not a weaker product. Formulators should select the form based on their target dose and label strategy.
Formulators building sleep, recovery, or mineral complex products frequently use zinc bisglycinate and magnesium glycinate in the same formula. Both are aminochelated, both are GI-gentle, and both carry glycine as the amino acid ligand, creating a coherent clean-label story for multi-mineral products.
This ingredient is processed in a facility that handles soy and peanuts. It is packaged alongside egg, coconut, and milk. Review allergen documentation before use in allergen-sensitive applications.

Zinc is essential for T-cell development and immune response. A primary application category, especially in post-COVID reformulation activity.
Frequently formulated alongside magnesium glycinate in mineral sleep complexes. Both chelated forms are GI-gentle and carry glycine.
Zinc plays a role in testosterone metabolism and reproductive health. Standard ingredient in men's health supplement formulas.
GI gentleness is especially valued in pediatric formulations. Zinc bisglycinate's neutral taste and tolerability make it suitable for chewables and gummies.
High solubility and neutral taste make it compatible with multi-mineral powders, sticks, and RTD formats.
