Cicero (WSYR-TV) - A viewer in Cicero asked how much Vitamin D they should take in a supplement, and if it was possible to take too much.
Vitamin D deficiency has been linked to an elevated risk of many cancers, heart disease, and immune system disorders such as MS, type-one diabetes and rheumatoid arthritis. It's hard to get enough D from the sun and from your diet and that's where supplements come in.
The current recommended intake is 200 units a day up to age 50, 400 units for adults 50 to 70 and 600 units for those over age 70.
Many experts, including the author of the new book 'The Vitamin D Solution,' says those recommendations are low. That book suggests taking a daily supplement of 1000 to 2000 units for all sun-deprived individuals, pregnant women and adults older than 50.
Experts say it is very hard to reach toxic levels of Vitamin D.
