Ascorbic acid

Original price was: $23,500.00.Current price is: $22,500.00.

Ascorbic acid, also known as vitamin C, is a water-soluble vitamin that plays an important role in various physiological processes in the human body. It is an essential nutrient that cannot be produced by the body and must be obtained through dietary sources or supplements. Ascorbic acid acts as a powerful antioxidant, protecting cells and tissues from oxidative damage caused by free radicals. It also plays a critical role in the production of collagen, which is important for the health of skin, bones, and other connective tissues. Additionally, ascorbic acid is involved in the synthesis of neurotransmitters and the metabolism of proteins and fats. Deficiency in ascorbic acid can lead to a range of health problems, including scurvy, a condition characterized by fatigue, weakness, and bleeding gums.

Ascorbic acid Uses

Food and Beverage:

Ascorbic acid is commonly used as a food preservative to prevent spoilage and discoloration of fruits, vegetables, and other foods. It is also added to many processed foods and beverages as a flavor enhancer and to provide additional nutritional value.

Nutritional Supplements:

Ascorbic acid is a common ingredient in dietary supplements and multivitamins, as it is an essential nutrient that the body cannot produce on its own. Supplements containing ascorbic acid are often used to prevent or treat vitamin C deficiency.

Pharmaceutical:

Ascorbic acid is used in various pharmaceutical applications, including the production of antibiotics, antihistamines, and pain relievers. It is also used as a reducing agent in the formulation of some drugs.

Cosmetic:

Ascorbic acid is used in many cosmetic products, including skin creams, lotions, and serums, as it is believed to have antioxidant properties that can help protect the skin from damage caused by free radicals. It is also used as a skin brightener and to promote collagen synthesis.

Water Treatment:

Ascorbic acid is sometimes used in water treatment as a reducing agent to neutralize chlorine and other disinfectants.
