Research over the past decade has reinforced the importance of Vitamin D in human nutrition. In the process, new roles in health maintenance related to immunity and chemoprevention have been added to the nutrient’s widely known benefits for skeletal health, and, indirectly, for tissue integrity. Vitamin D has now been shown to have a role in protecting against osteoporosis, cancers, autoimmune diseases, and high blood pressure, while supporting brain and immune function.*
Out of the new research has come a re-evaluation of ideal maximum daily intakes of Vitamin D. A consensus has evolved among researchers that the old RDI of 400 i.u. per day is inadequate. Instead, they point to ideal intakes of vitamin D3 ranging from 1,000 i.u. for infants, up through 2,000 i.u. for children and teenagers. Intake for adults is officially recommended at 2,000 i.u., although as we age, it becomes more difficult to absorb sufficient vitamin D. Therefore, some of the most respected researchers (e.g. Heaney, et. al.) insist that 4,000 to 10,000 i.u. are suitable for older adults in order to maintain immunity and skeletal health.*
Even though we now know more vitamin D is needed, widespread use of sunscreen and consumption of processed foods has placed increasing numbers of the population at risk of vitamin D deficiency. More persons than originally suspected have been found to be clinically deficient. Fortified foods and supplements can be used to maintain a desirable level of vitamin D nutrition in the nation’s food supply. Vibrant Health’s certified organic tablet provides a delivery vehicle for Vitamin D3 that is free of contaminants, genetically modified substances or other undesirable components.
Vitamin D3 is easily and safely held in circulation and in body tissues until it is needed. Then the kidneys convert circulating vitamin D to the hormonal form, calcitriol, or 1-25 dihydroxy vitamin D3 as needed. It is this hormonal form that, along with parathyroid hormone, stimulates retention of calcium by kidneys. Calcitriol improves the efficiency of calcium uptake from the intestines, raises circulating calcium levels, and helps drive calcium into bone. As a side benefit, parathyroid hormone secretion is lessened as circulating calcium increases. When that happens, osteoclasts, become less active. They are the cells that are directed by parathyroid hormone to tear down bone.
- Strengthens immunity
- Helps sustain a healthy skeleton
- Protects skin and brain
- Balances the immune response
Additional evidence has strongly suggested that vitamin D plays an important role in modifying the risk of type 2 diabetes, an effect which is likely mediated by an effect of vitamin D on beta cell function, insulin sensitivity and systemic inflammation.
