RE: Overuse of calcium

[Guest guest]

Adults ages 19-50 about 1000 mg per day and

it is believed that you can only absorb a maximum of 600 mg at a time, so split

this dose. Vitamin D for the same age group is 5 mcg or 200 IU. Most people

can get their Vitamin D quota from exposing skin to sunlight. Light skinned

people only need 5-10 minutes in the sun 2-3 times per week for a complete dose

of Vitamin D.

High calcium, vitamin D intake may have a down side

By Rauscher

NEW YORK

(Reuters Health) - In one of the first studies to examine

the relationship between diet and brain lesions, researchers observed

that elderly people who reported higher calcium and vitamin D intake

were much more likely to have greater volumes of brain lesions --

regions of damage that can increase risk of cognitive impairment.

" Our finding of a relationship between brain lesions and consumption

of both calcium and vitamin D raises the question about a possible

down side to high intakes of these nutrients, " Dr. Martha E. Payne

of Duke University,

Durham, North

Carolina, told Reuters Health.

Higher intakes of calcium and vitamin D have been promoted in recent

years as a way to prevent bone loss with aging. " We are concerned

that some of this extra calcium may end up in the blood vessel

walls rather than the bone. This may be a particular problem for

individuals with renal disease since calcium excretion may be

impaired, " Payne said.
