Overview

Nature Made packages 600 mg of calcium with vitamin D3 into softgels, sold in a 100 count bottle aimed at bone support. It is gluten free and unflavored.

The combination of calcium with D3 targets bone health, since D3 supports calcium absorption. It lists soy among its allergens, worth checking for anyone with a soy sensitivity.

Unflavored, easy to fit into a routine

Performance notes

Vitamin D3 is included alongside the calcium because D3 supports the body's calcium absorption, which is the usual reasoning behind pairing the two in a bone-support formula.
