Description

Vitamin D3 Palmitate is a fat-soluble ester derivative of cholecalciferol (Vitamin D3), where the hydroxyl group is esterified with palmitic acid. This chemical modification enhances the stability and lipid solubility of Vitamin D3, making it a preferred form for various fortified applications. It is a critical ingredient for manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to deliver the essential benefits of Vitamin D in stable, oil-based formulations.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in softgel capsules, liquid drops, and multivitamin blends for bone health and immune support.
• Functional Food & Beverage Fortification: Used to fortify dairy products (milk, yogurt), edible oils, margarine, and meal replacement shakes.
• Pharmaceutical Preparations: Employed in prescription and over-the-counter medications for treating and preventing Vitamin D deficiency and related disorders.
• Infant Formula & Pediatric Nutrition: Essential for meeting the nutritional requirements in formulas and growing-up milks.
• Cosmetic & Personal Care: Incorporated into skincare products for its potential role in skin cell metabolism and health.
• Animal Feed & Pet Nutrition: An important vitamin premix component for livestock, poultry, and pet food to ensure proper growth and calcium homeostasis.
