The proofreader gene recognizes mutated deoxyribonucleic acid (DNA) and cells. Vitamin D3 is an essential component used in this attempt by the body to rid itself of the cells. Vitamin D3 helps make protein for the functioning of the P53 gene, which is one of the body's main proofreader genes and cancer watchdogs. This gene helps prevent cancer by regulating protein production of specific oncogenes -- genes that, when mutated, can cause cancers. Indeed, vitamin D not only helps in the proper functioning of the gene, but also appears to actually help safeguard the P53 gene itself from genetic damage. Although studies still need to be done to confirm the link between vitamin D and cancer prevention, it is very possible that vitamin D does double duty by helping prevent aging of both the musculoskeletal and immune systems. When I think of vitamin D, I think of "defense." Vitamin D helps your body defend itself.
Vitamin D may also help protect the body from the onset and aging effects of arthritis, although this data is still somewhat speculative. Osteoarthritis is a disease that afflicts more than 10 percent of people who are sixty-five or older. It is painful, disabling, and aging. Recent studies have shown that taking calcium, vitamin C, and particularly vitamin D can retard the progression of arthritis and perhaps even prevent it's progression.
