Study Reports Possible Link Between Vitamin D and Reduced MS Risk
Medical Update Memo
January 16, 2004
“If people with MS are considering trying Vitamin D as a supplement, they should be aware that high doses of Vitamin D can be toxic, and they have been linked to heart problems and kidney failure,” he added. The publication Compendium of Pharmaceuticals and Specialties recommends a daily dosage of Vitamin D at 400 to 800 IU for adults. Those who believe in additional supplementation suggest that 1,000 to 4,000 IU daily can be taken without harmful side effects. People considering taking Vitamin D supplements should discuss it with
their physicians.
Excessive intake of supplemental vitamin D can have serious, toxic effects on the body, including excessive calcium levels in the blood, high blood pressure, nausea, anorexia, impaired kidney function and kidney damage".
