Vitamin C, the Super Antioxidant and a Powerful Immune System Booster

Overall, vitamin C supplementation had a mild beneficial effect compared to placebo. Not all common cold studies produce consistent results. Several case-control studies have found low serum 25-hydroxyvitamin D 3 concentrations in individuals with IDDM, MS, and SLE; among these individuals, lower serum 25-hydroxyvitamin D 3 concentrations have been associated with increased disease activity and relapse rates (108-110).

Many studies have shown that Vitamin C is able to not only reduce the incidence of colds, but also their duration and severity.

However, it wasn’t until the early 1930s that it was discovered that scurvy was caused by lack of vitamin C, and that taking the vitamin could cure the disease. Authorities occasionally recommended plant food to prevent scurvy during long sea voyages. Acute-phase proteins are a class of plasma proteins that are important in inflammation.

In helping bring about the processes of apoptosis and clearance by macrophages, Vitamin C helps protect host tissue from excessive damage. For example, Vitamin C is a cofactor for enzymatic reactions related to the biosynthesis of catecholamine hormones. These cells express surface receptors that identify pattern recognition receptors that are unique to pathogenic microorganisms but conserved across several families of pathogens (Figure 1) (2, 11). That said, the FDA encourages consumers to stay informed and "be wary of hype and headlines," saying that unsubstantiated claims crop up on supplement labels all the time and it's often up to you to spot them. In short, it seems that taking or consuming at least 500 mg of vitamin C daily may reduce the risk of heart disease.
