Overview

Capsule-form calcium paired with vitamin D3, sold in a 180-count bottle by Pure Encapsulations and positioned by the brand for bone, colon and cardiovascular support.

Pure Encapsulations is generally associated with minimal-additive formulations, and pairing calcium with D3 is standard practice since D3 assists calcium absorption. This listing carries no attribute data, so the specific calcium compound and per-capsule dose aren't confirmed here.
