Summary
This calcium supplement uses calcium citrate, a highly absorbable form of calcium, which is beneficial for bone health and muscle function. However, the presence of magnesium stearate, a controversial flow agent, may inhibit nutrient absorption and is a point of concern. The product contains a moderate number of additives, which slightly affects its overall formulation quality.
