Previous postings have review the intake of calcium and vitamin D. Here is a summary of some of the recommendations.
Calcium citrate (not calcium carbonate): 1000mg per day
Calcium carbonate will not be absorbed if you are taking medications to reduce stomach acid. The carbonate needs stomach acid to be broken down and absorbed.
Current daily requirements of Calcium
Child: 700mg
Teen-Young adult: 1300mg
Adult: 800mg
Pregnancy: 1500mg
Lactation (breast feeding): 2000mg
Post menopausal: 1500mg
Major fracture: 1500mg
Vitamin D3: 2000 units per day.
There seems to no disadvantage and there may even be a benefit to more Vitamin D.
Vitamin C: 500mg per day.
Thanks,
