Description

Cholecalciferol is the chemical form of Vitamin D3, a vital fat-soluble secosteroid essential for calcium and phosphate homeostasis in humans and animals. This high-purity compound is critical for ensuring product efficacy and safety in pharmaceutical and nutritional formulations. It is primarily required by manufacturers in the pharmaceutical, nutraceutical, food fortification, and animal feed industries seeking a reliable, high-quality active ingredient.

Application

• Pharmaceutical Formulations: Active pharmaceutical ingredient (API) in prescription and over-the-counter medications for treating and preventing Vitamin D deficiency, osteoporosis, and renal osteodystrophy.
• Dietary Supplements & Nutraceuticals: Key ingredient in softgel capsules, tablets, and liquid drops for general health, bone support, and immune system function.
• Food & Beverage Fortification: Used to enrich staple foods such as milk, dairy products, breakfast cereals, and fruit juices to address public health nutritional gaps.
• Animal Feed & Veterinary Products: Essential nutrient in premixes for poultry, swine, cattle, and pet food to ensure proper bone development, eggshell quality, and overall animal health.
• Cosmeceutical Preparations: Incorporated into skincare products for its potential role in skin cell growth, repair, and immune function.
• Research & Development: Reference standard and biochemical reagent in clinical, nutritional, and metabolic research studies.
