Our assessment
The evidence shows that calcium is essential for bone health, but the data on supplements like BulkSupplements.com Calcium Carbonate requires careful consideration. You need to be aware that some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Our assessment is that this supplement can be beneficial for meeting your calcium needs, but only if you are not getting enough from your diet and if you do not exceed recommended intakes.
How it works
Think of calcium as a building block for your skeleton and a messenger for your nerves and muscles. It supports bone density and mineral deposition through a process called bone mineralization, and it also supports muscle relaxation and nerve signaling [NIH ODS]. This means calcium is critical for keeping your bones strong and your muscles and nerves working properly.
Safety profile
FDA received 592,059 adverse event reports for this product category. The safety data shows that 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 [NIH ODS] [FDA data]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effect report counts for each specific symptom.
Our recommendation
Our recommendation is to assess your dietary calcium intake first. If you need a supplement, start with a moderate dose and take it with food for better absorption. Do not exceed the daily recommended intake without medical supervision. Because of the medication interactions, take calcium supplements at least two hours apart from your other medications. Discuss your calcium use with your doctor, especially if you have a history of kidney stones, heart disease, or prostate cancer [NIH ODS].
