Calcium from food and supplements: one-day total and dose-size tracker
Add up the calcium you get in a typical day from food, supplements and antacids, check each supplement dose against the 500 mg absorption limit, and compare the total with the amount recommended and the amount considered safe for your age. Take it to the prescriber who manages your Zepbound or your bones.
Each calcium product you use
Read the mg of calcium on the Supplement Facts or Drug Facts panel, not the weight of the tablet.
Product 1: name, form (citrate, carbonate or other), mg of calcium per tablet
Product 2, including antacids such as Tums or Rolaids
Vitamin D in any of these products, and how much
A typical day
| Time | Food, drink, supplement or antacid | mg of calcium | With a meal? | Running total (mg) |
|---|---|---|---|---|
Amounts to compare with
- Recommended daily amount: 1,000 mg for adults 19 to 50 and men 51 to 70; 1,200 mg for women 51 to 70 and everyone over 70.[1]
- Considered safe from food and supplements combined: up to 2,500 mg a day at 19 to 50, and 2,000 mg a day above 50.[1]
- Keep each supplement dose to 500 mg of calcium or less; absorption is best at that size.[1]
- Carbonate is absorbed better with food; citrate is taken up well with or without food. An antacid chew usually adds 200 to 400 mg.[1]
- High calcium intake over a long time raises kidney-stone risk in some people; in the WHI trial, 1,000 mg of calcium with vitamin D a day raised kidney stones (hazard ratio 1.17).[2]
Before adding or changing a calcium supplement
- Counted what I already get from food and drinks on a normal day
- Checked whether eating less on Zepbound has lowered that amount
- Split supplement doses so none is over 500 mg of calcium
- Told the prescriber if I take levothyroxine, alendronate or an acid reducer
- Mentioned any past kidney stones
- Checked whether my vitamin D is already in the calcium product
For the prescriber or pharmacist
- Do I need a supplement at all, or can food cover my daily amount?
- Is citrate or carbonate the better form for me, given my other medicines?
- With my heart and kidney history, is there a total I should stay under?
- Should my bone density be checked while I am losing weight?
