Our assessment
The evidence shows that MegaFood Calcium, Magnesium & Potassium is a mineral supplement that can support your bone health and muscle function. Based on the data provided, the primary active ingredient with available research is calcium, which plays a key role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, data for magnesium and potassium is not available in the provided information, so our assessment focuses on calcium.
How it works
Think of calcium as a structural builder and signaler for your body. It supports bone density and mineral deposition, helping keep your skeleton strong. Additionally, it aids in neuromuscular relaxation and nerve signaling, which means it helps your muscles relax and your nerves communicate properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in your 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].
Our recommendation
You should take this supplement only if you have a confirmed need for these minerals, particularly calcium. Be cautious about your total calcium intake from all sources, as high levels carry significant risks. If you take any medications listed above, separate them from this supplement by at least 2 hours. Start with the lowest effective dose and consult your healthcare provider to monitor your blood levels and kidney function [NIH ODS].
