The current recommended intake of vitamin D, established by the Institute of Medicine, is 200 I.U. a day-10% of what is now deemed needed in order to stay healthy and 2,000 I.U. a day is still low.
Nutritional deficiencies are at the heart of most disease.
Although more foods today are supplemented with vitamin D, experts say it is rarely possible to consume adequate amounts through foods. The main dietary sources are wild-caught oily fish (salmon, mackerel, bluefish, and canned tuna) and fortified milk and baby formula, cereal and orange juice.
Studies indicate that the effects of a vitamin D deficiency include an elevated risk of developing (and dying from) cancers of the colon, breast and prostate; high blood pressure and cardiovascular disease; osteoarthritis; and immune-system abnormalities that can result in infections and autoimmune disorders like multiple sclerosis, Type 1 diabetes and rheumatoid arthritis.
So the daily dosage will now be increased from 400 IU to close to 2,000. Two years ago they said you could OD on Vitamin D yet:
Healthy adults have taken 10,000 I.U. a day for six months or longer with no adverse effects. People with a serious vitamin D deficiency are often prescribed weekly doses of 50,000 units until the problem is corrected.
Seems on cannot OD on sunshine but lack of sun does kill you. What htey are missing here is Vitamin D as it relates to Calcium for higher doses of Vitamin D mena higher levels Calcium,a good thing to a point for the article skirts it but fails to see it.
Symptoms of vitamin D toxicity include nausea, vomiting, poor appetite, constipation, weakness and weight loss, as well as dangerous amounts of calcium that can result in kidney stones, confusion and abnormal heart rhythms.
If we focused more on keeping people well rather than “fixing them” after the fact, health care would be manageable.
