Vibrant Health Vitamin D-3  4000 I.u, Organitabs, 100-Count
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 reevaluation 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.
