Vitamin C is also known as ascorbic acid. This acid often causes stomach upset due to the acidic nature which presents difficulty to the body to absorb the vitamin. Sodium ascorbate is an alternative form of Vitamin C that is more alkaline and bioavailable for the body. Bioavailable means that sodium ascorbate or Vitamin C is absorbed into the body at higher concentrations. However, the sodium content of this form of Vitamin C is considered excessive. Sodium intake should be limited or the extreme level of sodium could aggravate existing conditions such hypertension or heart failure. This alternative form of Vitamin C acts as a food additive or supplement to potentially assist with heart attack prevention, ward off chronic infections and deter cancer throughout the body. The primary functions of Vitamin C are to act as an antioxidant and to promote the health of the skin, bones, teeth, blood vessels and cartilage.
