The evidence shows that the calcium in this formula supports bone density and neuromuscular function [NIH ODS]. However, we must be clear that the data provided is limited to a single ingredient, so a complete evaluation of this specific product is not possible.
How it works
The calcium in this supplement acts as a master regulator for your body. It supports bone mineralization, helping to deposit minerals into your skeleton for strength. It also promotes neuromuscular relaxation, which is essential for proper muscle function and nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer.

Because the data does not provide a specific dosage for this formulation, you should consult your healthcare provider before starting, especially if you take prescription medications.
