Vitamin C (L-Ascorbic Acid) is a water-soluble vitamin and a potent antioxidant. It plays a crucial role in collagen synthesis, immune function, and acts as a reducing agent to neutralize free radicals, thereby protecting cells from oxidative damage.
In food systems, it functions as an oxygen scavenger, preserving color and flavor.
Food & Beverage: Used as an antioxidant to prevent spoilage, color degradation, and nutrient loss in processed foods, beverages, and meats (e.g., preventing nitrosamine formation). Also used as a flour improver in baking.

Dietary Supplements: A key ingredient in multivitamins and immune-support formulations, typically at dosages ranging from 60 mg to 1000 mg per serving.

Animal Feed: Added to premixes for poultry, swine, and aquaculture to promote growth, improve feed conversion, and enhance stress resistance. Recommended inclusion rates vary by species.
