Description

Ester C is a patented, non-acidic, and highly bioavailable form of ascorbic acid (Vitamin C). This advanced compound is specifically engineered to offer superior stability and enhanced absorption compared to traditional ascorbic acid, making it a critical ingredient for high-performance formulations. It is essential for manufacturers in the nutraceutical, pharmaceutical, and functional food and beverage industries seeking to improve product efficacy and consumer benefits.

Application

• Dietary Supplements & Nutraceuticals: Used as a primary or complementary source of Vitamin C in capsules, tablets, and softgels for immune support and antioxidant benefits.
• Functional Foods & Beverages: Incorporated into fortified juices, nutritional bars, and dairy products due to its non-acidic nature and improved stability.
• Pharmaceutical Preparations: Utilized in formulations where a gentle, well-tolerated, and highly bioavailable source of ascorbic acid is required.
• Cosmeceuticals & Skincare: A key active ingredient in anti-aging serums, creams, and lotions for its antioxidant properties and role in collagen synthesis.
• Animal Nutrition (Feed Premixes): Added to veterinary supplements and feed to support animal health and vitality.
• Sports Nutrition: Included in recovery drinks and performance supplements to aid in reducing oxidative stress post-exercise.
