Zinc glycinate

Zinc glycinate (CAS 14281-83-5), also known as zinc bisglycinate, is an amino acid-chelated zinc mineral in which zinc is coordinated with glycine for enhanced bioavailability compared to inorganic zinc salts.

Where is Zinc glycinate used?

• Dietary supplements: preferred zinc source for gastrointestinal tolerability
• Functional foods: absorption efficiency as a key product differentiator
• Animal feed: organic trace mineral supporting immune function and growth performance in livestock and aquaculture
• Cosmetics and personal care: skin-conditioning active and mild preservative booster in creams, serums, and anti-acne products
• In cosmetics it acts as a sebum-regulating and mild antimicrobial active in anti-acne serums and face creams.
• In veterinary medicine it is used in oral zinc-supplemented preparations to reduce gastric irritation.
• Agriculture: foliar sprays and soil amendments where chelated zinc corrects micronutrient deficiencies
• It performs more effectively than sulfate alternatives in various environmental conditions.

Good to know: Buyers should confirm the chelation ratio and elemental zinc assay when evaluating specific supplier technical data sheets.

Formulation notes

• Zinc glycinate is a third-generation trace element additive that avoids the mutual antagonism between minerals and the defect of inorganic salts oxidizing vitamins.

Typical specification

• Zinc content is at least 23.4%.
• Assay is at least 98.0%.
• Lead content is not more than 0.0005%.
• The zinc content ratio is certified on a lot basis and is the primary reference for the buyer's formulation calculations.
• Available in bulk as direct compression (DC) granular or DC grade.

Regulatory status

• Classified for transport in class 9, packing group III, UN number UN3077.

Storage, packaging and handling

• Stored at ambient temperature.
• Commonly packaged in 25 kg bags.
