Vitamin D Deserves an “A”
Noel Peterson, N.D.
What if there was one vitamin that has been proven to prevent osteoporosis, cut the risk of breast cancer by 50%, cut the risk of colon cancer by 58%, cut the risk of prostate cancer by 60%, prevent depression, prevent knee osteoarthritis, prevent hip fractures in women, boost viral immunity and prevent autoimmune disease? Would you be interested? What if I told you that less than 10% of those reading this have enough of this vitamin to do much more than prevent Rickets, and that this vitamin is not a vitamin at all, but a hormone made in your skin? Would you guess that this substance is known as 25(OH)D, or vitamin D?
Sadly, most people don’t know the truth about vitamin D, or that the RDA of 400 iu for vitamin D is less than 10% of what is required to prevent cancer, osteoporosis, heart disease and depression. That’s because the RDA was originally based on the dose required to prevent Rickets, a bone softening disorder, and was never intended to be a recommendation for preventing other diseases.
