Calcium + D3
Os-Cal Calcium + D3 is a bone health supplement featuring Calcium at 500mg and Vitamin D3 at 200IU, with a total of two ingredients. The Calcium dosage of 500mg is noted to be at a clinically studied level, which is beneficial for bone support. However, the Vitamin D3 component is identified as underdosed, which may impact its ability to optimize calcium absorption. The product has an N+ Score of 55, resulting in an 'F' grade, reflecting that despite the adequate calcium, the overall formulation has notable weaknesses. This supplement may be considered for basic calcium intake, but a higher Vitamin D3 dosage is often recommended for comprehensive bone health.
