Major Calcium 600 mg + D3
Brand: Major · Form: TABLET [E0155]
Our assessment
The evidence shows that this supplement combines calcium with vitamin D to support bone health. Our assessment: For most adults, getting these nutrients from food is preferred, but a supplement can help fill dietary gaps. You should be aware that the data on high calcium intake includes some important safety considerations [NIH ODS].
How it works
Think of calcium as the building block your body uses for bone mineralization and density. It also supports neuromuscular relaxation and nerve signaling. The vitamin D in this product helps your body absorb that calcium more effectively [NIH ODS].
Safety profile
Data not available on specific adverse events for this exact product. However, for calcium supplements generally, FDA received 592,059 total adverse event reports. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine 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 [FDA data] [NIH ODS].
Our recommendation
Our recommendation: Do not exceed 600 mg of supplemental calcium without a doctor's guidance. You should be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take this supplement at a different time than these medications [NIH ODS].
