Major Calcium 600 mg + D3 400 IU
Brand: Major · Form: TABLET [E0155]
Our assessment
The evidence shows that Major Calcium 600 mg + D3 400 IU is a standard supplement for supporting bone health. The combination of 600 mg calcium and 400 IU vitamin D3 is a common formulation, but you must consider your total daily intake from food and other supplements to avoid exceeding safe limits [NIH ODS].
How it works
Think of this supplement as providing the building blocks and the helper for your skeleton. The calcium works through bone mineralization, supporting bone density and mineral deposition, while also aiding in neuromuscular relaxation and nerve signaling [NIH ODS]. The vitamin D3 helps your body absorb that calcium effectively [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports across all supplement categories. For this specific product, data on side effects is not available. However, high calcium intakes from all sources might increase the risk of heart disease and prostate cancer. Excess calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your total daily calcium intake from diet and other supplements. The amount in this product is a good starting point, but you should not exceed the tolerable upper intake level without medical supervision. Always take calcium supplements with food for best absorption, and take them separately from the medications listed above by at least two hours [NIH ODS]. For a personalized recommendation, consult your healthcare provider.
