Major Calcium 600 mg + D3 200 IU
Brand: Major · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this combination of calcium and vitamin D3 is a well-established approach for supporting bone health. For most adults, the 600 mg of calcium plus 200 IU of vitamin D3 provides a meaningful contribution toward your daily needs, but it is not a complete replacement for dietary intake. [NIH ODS]
How it works
Calcium acts as a key building block for your bones, supporting bone mineralization and density, while also playing a role in muscle relaxation and nerve signaling. Vitamin D3 helps your body absorb that calcium efficiently. Think of this supplement as providing the raw materials your skeleton needs to stay strong. [NIH ODS]
Safety profile
FDA received 592,059 total adverse event reports across all products, though specific data for this exact formula is not available. For calcium, potential side effects include constipation, nausea, and weight loss. Very high calcium intakes may increase the risk of heart disease, prostate cancer, and abnormal heart rhythms. [NIH ODS] [FDA data]
Our recommendation
This supplement is a reasonable choice if you struggle to get enough calcium from food. However, you should be aware that calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine. Take it at least two hours apart from these drugs. [NIH ODS]
