Nature Made Calcium 600mg with D3
by Nature Made
"USP Verified calcium + D3 — 600mg calcium carbonate with 800 IU D3 for bone health from the #1 pharmacist-recommended brand"
Overview
Nature Made Calcium 600mg with D3 provides 600mg of calcium from calcium carbonate with 800 IU (20mcg) of vitamin D3 for enhanced calcium absorption. Calcium carbonate provides the highest elemental calcium per gram (40%) and is best absorbed when taken with food (stomach acid aids absorption). The 800 IU D3 ensures adequate vitamin D for calcium absorption — a critical pairing since vitamin D deficiency impairs calcium uptake by up to 65%. With 220 tablets and USP Verified quality, this is the mainstream bone health supplement.
