Can someone explain the discrepancy between the nutrition facts and the active ingredient. It says 1000 mg of calcium in the active ingredient per tablet and in the nutritional facts it gives 800 mg per 2 tablets. See attached

My guess is that calcium carbonate is both calcium and carbonate, basically a salt, so it weighs more than just calcium alone.

It still doesn't add up. Look at the sodium content.

Sodium is not carbonate. A salt is a general word for an ionic solid that dissolve in water. For example, table salt, is sodium chloride. When is dissolve in water you get positively charged sodium ions and negatively charged chloride ions. Calcium carbonate is another kind of salt. When dissolved you have positive sodium ions and negative carbonate. So the sodium content has Nothing to do with the calcium carbonate content. They're don't have to add up.

Thanks professor Venus

Basic chemistry we learn in high school. No need for the title professor, but I'll gladly accept it.

Isnt calcium an element as Is sodium

Yes. Different elements. Sodium ions have a +1 charge and calcium ions have +2 charge. Therefore, their pair has equal opposite charge to give you a neutral salt. Chlorine ions are -1 and carbonate, Which is not an element but a molecule, is -2.

Calcium carbonate is 40% elemental calcium. 1000 mg will provide 400 mg of calcium. However, supplement labels will usually indicate how much calcium is present in each serving, not how much calcium carbonate is present.

You are making my point. So calcium and sodium are different elements. Then my question isn't answered. Please don't get into the minutia of it. (Elements)

Thanks that explains it

The difference is just water, it has no nutritional value

The sodium comes from somewhere else, not the calcium carbonate.
