Nature Made Calcium Magnesium Zinc

Our assessment

Our assessment: This supplement provides a combination of three essential minerals. For bone health, the evidence is strongest for calcium, which supports bone density and mineral deposition [NIH ODS]. However, you should be aware that the data on this combination is limited, and the specific benefits depend heavily on your individual dietary intake. We do not have specific data on the exact amounts of each mineral in this product, so the general risks and benefits for each ingredient apply.

How it works

Think of calcium as a building block for your bones and a key player in nerve signaling and muscle relaxation [NIH ODS]. The evidence shows that calcium works with other minerals like magnesium and zinc, though the specific role of this exact combination is not detailed in the provided data. It is important to note that calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Safety profile

The FDA received a total of 592,059 adverse event reports for all supplements, though this number is not specific to this product. 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].
