Our assessment
The evidence shows that calcium is essential for bone health, but the data requires careful attention to dosage and safety. For a 600 mg supplement, you are getting a significant portion of the daily recommended intake, but your total intake from all sources must be managed [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a role in muscle relaxation and nerve signaling [NIH ODS].
