Brand: DC · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that DC Magnesium is a product containing the mineral calcium. Our assessment: calcium is well-supported for bone health, but it comes with notable safety considerations. You need to be aware of specific risks and drug interactions before adding this to your routine [NIH ODS].
How it works
Think of calcium as a structural building block and a nerve regulator. It supports bone mineralization, helping maintain bone density, and it also plays a role in neuromuscular relaxation, which supports proper muscle and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement products. For calcium specifically, safety concerns include that high 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 [NIH ODS] [FDA data].
Our recommendation
Do not take calcium supplements without first reviewing your current medications. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, data not available on safety for your specific case — consult your doctor before use [NIH ODS].
