Lindberg Calcium Citrate Plus Magnesium 360 Capsules

What the brand says

Calcium Citrate plus Magnesium provides an easily absorbed citrate form of calcium to build and maintain healthy bones and teeth.* In human studies, calcium absorption from calcium citrate was 22% to 27% higher than the carbonate form of calcium. Calcium citrate is also ideal for those with low stomach acid levels. Magnesium is added to create a balanced calcium to magnesium ratio.
