Mineral Chelates
Stable mineral coordination complexes in which mineral ions are chemically bound to organic ligands — widely used in dietary supplements, functional foods, beverages, sports nutrition, and animal nutrition.
Stable mineral delivery for nutritional formulations
Mineral chelates form when a mineral ion binds to an organic ligand — typically an amino acid, peptide, or organic acid — creating a stable coordination complex. This binding helps protect the mineral during food processing and storage while providing formulation flexibility across nutritional products.
A mineral chelate consists of a mineral ion and an organic ligand bound through coordinate chemical bonds, forming a ring-like chelate complex. Unlike simple mineral salts, the mineral remains chemically associated with the ligand until the complex dissociates under physiological or processing conditions.
Common chelated minerals include iron, zinc, magnesium, calcium, copper, manganese, chromium, selenium, potassium, and molybdenum — with ligands such as glycine, lysine, methionine, citric acid, malic acid, and gluconic acid depending on application.
High-purity mineral sources react with approved food-grade ligands under controlled temperature, pH, and concentration — followed by purification, drying, and quality testing for mineral content, chelation quality, purity, and microbiological compliance.

Introduction
Mineral Chelates are mineral compounds in which a mineral ion is chemically bound to an organic ligand, typically an amino acid, peptide, or organic acid. This binding forms a stable complex that helps protect the mineral during food processing and storage while providing formulation flexibility for nutritional products.
Widely used in dietary supplements, functional foods, beverages, sports nutrition, infant nutrition (where permitted), medical nutrition, and animal nutrition — common chelated minerals include iron, zinc, magnesium, calcium, copper, manganese, chromium, and selenium.
Chemical Characteristics
- Stable coordination complexes with controlled mineral-ligand binding
- Good compatibility with food formulations
- Variable water solubility depending on ligand type
- High manufacturing consistency
Manufacturing Process
- Raw Material Selection — High-purity mineral sources and approved food-grade ligands
- Dissolution — Mineral and ligand dissolved under controlled conditions
- Chelation Reaction — Temperature, pH, concentration, and mixing controlled for chelate formation
- Purification — Filtration, membrane separation, or crystallization
- Drying — Supplied as powder, granules, or liquid
