Advanced Mineral Chelates & Salts for Maximum Bioavailability

Mineral Chelates & Salts Overview

Mineral ingredients are inorganic or organically bound forms of essential minerals used as bulk raw materials in dietary supplements, functional foods and fortified beverages. Purecium supplies mineral chelates and salts covering magnesium, calcium, zinc, chromium, iron and potassium, in forms selected for bioavailability, stability and finished-product compatibility. Chelated forms such as magnesium bisglycinate and zinc glycinate bind the mineral to an amino acid for better absorption, while well-defined salts such as magnesium oxide, calcium carbonate and potassium citrate offer reliable elemental content at economical cost.

This B2B guide explains how our mineral ingredients are identified, manufactured, tested and supplied for supplement manufacturing, with specifications aligned to USP-NF or European Pharmacopoeia methodology where monographs exist.

Elemental content is the commercial unit of mineral trading, so our specifications state both the compound purity and the elemental yield, and the Certificate of Analysis reports the assay used for each. Buyers comparing quotes across suppliers should compare elemental price, not compound price, and our team provides conversion guidance as part of the quotation.

Source & Ingredient Identity

Every mineral ingredient is defined by its chemical form, elemental content and specification. Identity is confirmed by assay and, for chelates, by reaction-completion testing so buyers can rely on the declared elemental yield. A synonym and the chemical identity of representative products are listed below for cross-checking against references such as PubChem.

Magnesium Bisglycinate - CAS 14783-68-7; molecular formula C4H8MgN2O4; molecular weight 172.42 g/mol. A fully reacted chelate with high water solubility, supplied at 14.1-14.4% elemental magnesium by assay.

Magnesium Oxide - CAS 1309-48-4; molecular formula MgO; molecular weight 40.30 g/mol. Supplied as heavy or light powder with 98% minimum assay.

Zinc Gluconate - CAS 4468-02-4; molecular formula C12H22O14Zn; molecular weight 455.68 g/mol. Supplied as powder with 97-102% assay.

Chromium Picolinate - CAS 14639-25-9; molecular formula C18H12CrN3O6; molecular weight 418.31 g/mol. Supplied at 0.4% or higher chelate concentrations for micro-dose formulations.

Potassium Citrate - CAS 866-84-2; molecular formula C6H5K3O7; molecular weight 306.40 g/mol, and Ferrous Fumarate - CAS 141-01-5; molecular formula C4H2FeO4; molecular weight 169.90 g/mol. Calcium chelates and organic salts, including calcium citrate and calcium citrate malate, are available with elemental calcium content declared on the specification.

Key Characteristics of Mineral Ingredients

The defining characteristics of a mineral raw material are elemental content, chelation or salt form, solubility, particle size and heavy-metal profile. Chelated minerals deliver higher bioavailability at lower inclusion rates; inorganic salts provide higher elemental density and lower cost per serving. Particle engineering controls flow, compaction and blend uniformity, and all grades are produced to minimize lead, arsenic, cadmium and mercury so finished products meet global limits.

Sensory and physical properties are matched to the application: fine powders for capsules, granular or densified forms for direct-compression tableting, and soluble citrate and glycinate forms for stick packs, effervescents and ready-to-drink products. Clean-label and vegan status applies across the range, with non-GMO and non-irradiation status confirmed per batch.

Mineral Ingredients Manufacturing

Mineral salts are produced by controlled reaction, crystallization, purification, drying and milling processes; chelates are formed by reacting the mineral with the specified amino acid under controlled pH and temperature, followed by drying and particle sizing. Reaction-completion testing confirms that free mineral and free amino acid levels are within specification, which is the key quality attribute of a true chelate.

Production follows GMP principles under ISO 9001 and FSSC 22000 certified management systems. Standard packing is 25 kg per drum with food-grade inner liner, with smaller evaluation lots available. Every production lot is quarantined until quality control release.

Applications of Mineral Ingredients

Mineral ingredients support bone health (calcium, magnesium), muscle function and relaxation (magnesium), immune and skin health (zinc), glucose metabolism (chromium), oxygen transport (iron) and electrolyte balance (potassium). Regulatory agencies including the NIH Office of Dietary Supplements publish reference intakes and safety reviews for these minerals, which formulators use when setting dose levels and label declarations.

Product formats span tablets, capsules, powders, chewables, gummies and beverages. For each format we recommend the mineral form and particle grade, and we can supply stability and compatibility data to support your development work.

Dose-response and safety references are published by bodies such as the NIH Office of Dietary Supplements and the European Food Safety Authority, and our documentation packages the assay data and impurity profile needed for your regulatory file in each target market.

Manufacturing & Quality Control

Every batch is tested for identity, assay and elemental content, heavy metals, microbial limits, loss on drying and particle size. Analytical methods follow current USP-NF and European Pharmacopoeia monographs where they exist, complemented by AOAC-based procedures and atomic absorption or ICP analysis for elemental content confirmation.

Kosher and Halal certifications are available for designated products, and a full Certificate of Analysis accompanies every shipment. Retained samples are kept for traceability, and customer audits are welcome under confidentiality agreements.

Mineral Ingredients for B2B Supplement Manufacturing

Purecium supplies mineral chelates and salts to distributors, contract manufacturers, private-label producers and supplement brands worldwide, with more than 15 years of nutraceutical export experience. Standard MOQ is 25 kg per item with drum packing, full COA and SDS documentation, and a lead time of 7-15 days for stocked materials, with global shipping arranged by sea, air or express.

Samples with specifications are provided for evaluation before bulk commitment, and regulatory documents such as flowcharts, allergen statements and stability summaries can be shared under NDA. Our sales and quality teams answer with documented technical data rather than generic quotations.
