Overview
Thorne's Calcium capsules use DiCalcium Malate, branded DimaCal, as a chelated calcium form intended to support absorption and bone density. Each bottle holds 120 capsules and is unflavored and gluten free.
This is a single ingredient chelated calcium product rather than a multi mineral blend, which sets it apart from combination bone health formulas that pair calcium with magnesium or vitamin D. Thorne markets the DimaCal form specifically for absorption, though the listing data does not include a milligram per serving figure.
- Chelated calcium as DiCalcium Malate (DimaCal)
- 120 capsules
- Unflavored, gluten free
- Bone density support
Who it's for
Fits people who already take other minerals separately and want calcium on its own, or who have been advised to avoid extra additives. Less useful for someone who wants a single capsule covering multiple bone support nutrients at once.
