Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the safety profile includes important risks you need to know. The FDA has received 592,059 total adverse event reports related to products containing this ingredient [FDA data]. Our assessment is that calcium supplementation should be approached with caution and only when dietary intake is insufficient.
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body relies on a steady supply of calcium to keep these systems functioning properly.
Safety profile
High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for specific side effect report counts for this ingredient alone from the provided FDA data.
Our recommendation
Do not exceed the recommended dietary allowance without medical supervision. Get your calcium primarily from food sources, and only use supplements if your diet falls short. Check for interactions with any medications you take, especially antibiotics and thyroid medication [NIH ODS]. Speak with your doctor before starting calcium supplements, particularly if you have a history of kidney stones or heart conditions.
