How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, ensuring your bones remain strong. It also acts as a neuromuscular regulator, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, safety data shows that high intakes might increase the risk of heart disease and prostate cancer. Very 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].
Our recommendation
Start by assessing your dietary calcium intake before considering supplements. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Talk to your doctor about whether a calcium supplement is right for you, especially if you take any of these medications.
