Vitamin D: How Much Do You Need? continued...

Fiscella says it is too soon to recommend taking vitamin D supplements to improve heart health.

"We really don't know what the optimal levels are at this point, or if there is a downside to taking double or triple the recommended amount," he says.

The National Osteoporosis Foundation recommends that adults under 50 get 400 to 800 international units (IU) of vitamin D a day and that older adults get 800 to 1,000 IU.

Current federal nutrition guidelines consider 200 IU of vitamin D daily adequate for children and adults up to age 50 and 400-600 IU daily adequate for older adults.

But a government advisory panel is reviewing this recommendation and is expected to revise it later this year.

James H. O'Keefe, MD, who directs the preventive cardiology program at the Mid America Heart Institute in Kansas City, Mo., considers the current recommendations far too low.

"Three out of four Americans are not getting enough vitamin D," he tells WebMD. "In my opinion, 1,000 IU to 2,000 IU a day is probably safe for anyone to take. That may be enough for some people but not for others."

He says African-Americans and other dark-skinned people may need even more vitamin D to avoid deficiency.

Milk and other dairy products are good dietary sources of vitamin D, as are oily fish such as salmon, tuna, and mackerel. But it would be difficult, if not impossible, to get enough vitamin D from food sources alone, O'Keefe says.
