Sodium Ascorbate, also called sodium ascorbate, is a salt form of vitamin C. Here is a description of sodium ascorbate and some common uses:

Description: 

•Chemical properties: Sodium ascorbate is a white crystalline powder that is soluble in water. It is a stable form of vitamin C and has similar chemical properties to vitamin C.

•Source: Sodium ascorbate can be prepared by the reaction of vitamin C with sodium powder (sodium hydroxide).

Purpose: 

1. Vitamin C supplement: Sodium ascorbate is a form of vitamin C supplement. Vitamin C is essential for many physiological functions in the body, including immune support, antioxidant action, collagen synthesis, and more. Sodium ascorbate can be used as an alternative form of vitamin C to meet the body's vitamin C needs.

2. Antioxidant effect: Sodium ascorbate has antioxidant properties, which can help clear free radicals in the body and reduce the damage of oxidative stress to cells. Antioxidant effects help maintain the health of cells and tissues, slow down the aging process, and may play a protective role in preventing chronic diseases.

3. Immune support: Vitamin C plays an important role in the body's immune system. Sodium ascorbate supplements can enhance immune function, improve resistance, and help prevent and relieve infectious diseases.

4. Collagen synthesis: Vitamin C is an essential nutrient for collagen synthesis. Collagen is an important component of skin, bones, blood vessels and other connective tissues. The intake of sodium ascorbate promotes collagen synthesis, which helps maintain healthy skin, joints, and bones.

5. Iron absorption: Sodium ascorbate can increase the absorption rate of iron in non-animal foods. Vitamin C combines with iron ions to form soluble complexes, which contributes to the absorption and utilization of iron and helps to prevent iron deficiency anemia.
