Description

2-amino-9-[3,4-dihydroxy-5-[[oxido-(oxido-phosphonatooxy-phosphoryl)ox y-phosphoryl]oxymethyl]oxolan-2-yl]-3H-purin-6-one, chromium(+3) cation, hydrogen(+1) cation, tetrahydrate is a complex chromium coordination compound of a phosphorylated nucleoside derivative, commonly known as chromium picolinate's more bioavailable analog. This compound matters for its role as a highly stable and bioavailable source of trivalent chromium, an essential trace mineral involved in macronutrient metabolism and insulin function. It is primarily needed by manufacturers in the nutraceutical, pharmaceutical, and functional food industries for formulating dietary supplements and specialized nutritional products.

Application

• Dietary Supplement Formulation: As a key active ingredient in capsules, tablets, and softgels for chromium supplementation.
• Functional Food & Beverage Fortification: For enrichment of health drinks, meal replacement shakes, and nutritional bars.
• Veterinary Nutrition: Used in premixes and feed additives for livestock and companion animal health.
• Pharmaceutical Research: Serves as a reference standard and active pharmaceutical ingredient (API) in metabolic disorder research.
• Sports Nutrition Products: Incorporated into formulations aimed at supporting energy metabolism and lean body mass.
• Clinical Nutrition: For use in medical nutrition products designed for glucose management.

Quality Control

Our Chromium Polynicotinate is produced under strict quality management systems. Each batch undergoes rigorous testing to ensure it meets high-purity standards suitable for human consumption, with specifications typically aligned with nutraceutical and FCC-grade requirements. Comprehensive testing includes assay for chromium content, identification, and limits for heavy metals and residual solvents. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
