Our assessment
The evidence shows that Sundown Naturals Calcium Magnesium and Zinc is a well-chosen combination of three essential minerals. Our assessment: This supplement can be a practical way to support your bone health and daily mineral intake, provided you use it correctly. The key ingredient, calcium, is critical for bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as the building block for your bones and a signal messenger for your muscles and nerves. It works by supporting bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. This product combines calcium with magnesium and zinc, which often work together in the body for overall health support.
Safety profile
Data not available for specific side effect reports for this product. However, FDA has received a total of 592,059 adverse event reports across all supplement products [FDA data]. For calcium specifically, high intakes can lead to serious risks, including constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease. High levels of calcium in the blood and urine can also cause poor muscle tone and poor kidney function [NIH ODS]. Additionally, calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: You can take this supplement to support your bone and muscle health, but do so with caution. To avoid side effects, do not exceed the recommended dose on the label. If you take any prescription medications, especially those listed in the safety profile, separate your supplement dose by at least two hours. Always consult your doctor before starting, particularly if you have a history of kidney problems or heart disease [NIH ODS].
