600+D3 Plus Minerals

America's most recommended calcium supplement uses every budget form: calcium carbonate (needs stomach acid you may lack), magnesium oxide (4% absorption), zinc oxide (poorly absorbed). The minerals are on the label, not in your bones. Add K2 or switch to citrate.

5.0/10
DECENT

The iconic bone supplement with a hidden problem: calcium carbonate at 600mg in one dose (body maxes at 500mg), magnesium as oxide (4% absorption), zinc as oxide. The minerals exist on paper, not in your bloodstream.
