Our assessment
The evidence shows that calcium is a well-studied mineral, but it comes with significant safety considerations. For a general audience, it is essential to understand that calcium from supplements is not without risks, and you should approach it with caution. The data provided does not include specific findings for the product Carlson Chelated Iron 27 mg, so our assessment focuses on the active ingredient calcium as listed in the data.
How it works
Think of calcium as a structural builder and a signal messenger. It supports bone density and mineral deposition through bone mineralization, and it helps your muscles relax and your nerves signal properly through neuromuscular relaxation [NIH ODS]. This dual role is why calcium is critical for both your skeleton and your nervous system.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high 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 on side effect report counts specific to calcium supplements.
Our recommendation
Our recommendation: Do not start a calcium supplement without first discussing it with your doctor. Because of the potential for serious side effects and interactions with common medications, you should rely on dietary sources first and only use supplements under medical supervision [NIH ODS]. Always check your calcium intake from all sources, including food and other supplements, to avoid exceeding safe levels.
