Products Description

Ascorbic acid, also called vitamin C, is a vital nutrient for humans and higher primates. Most organisms can synthesize it internally, but humans cannot. Insufficient vitamin C may lead to scurvy. It acts as a key antioxidant that defends the body against oxidative stress and also functions as an important coenzyme in multiple metabolic reactions.Ascorbic Acid

Product Application

Vitamin C supports diverse body metabolic processes, promotes growth, and strengthens disease resistance. It is widely used as a nutritional fortifier in candy, cereals, infant foods, canned fruits, beverages, and fruit purees in line with regulatory standards. With strong reducibility, it serves as an antioxidant in fermented flour products and beer. It promotes folic acid conversion, enhances iron absorption, supports collagen formation, neutralizes toxins, and stimulates antibody production. Clinically, it prevents and treats scurvy and supports management of dental, gingival, hematological, and growth‑related disorders.
