Our assessment
The evidence shows that the combination of calcium, magnesium, and potassium in MegaFood Calcium, Magnesium & Potassium can support several key body functions, but the most robust data is available for calcium. For this mineral, we see strong support for bone health and nerve signaling [NIH ODS]. However, you need to be aware of the specific risks and medication interactions associated with calcium supplementation before starting.
How it works
Think of calcium as a structural building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests 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]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
