Our assessment
The evidence shows that this supplement, Higher Nature Vitamin D3, contains calcium as an ingredient. Data for the specific vitamin D3 content is not available. For the ingredient calcium, the data supports its role in bone health, but we must be very careful with dosing and interactions. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural building block and a signaling molecule. It supports bone mineralization and density, and it is essential for proper muscle relaxation and nerve signaling [NIH ODS].
