Sundown Naturals Calcium Magnesium And Zinc
Brand: Sundown Naturals · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Sundown Naturals Calcium Magnesium And Zinc provides foundational minerals for bone health and muscle function. Our assessment: this combination can be helpful if you are not meeting your daily needs through diet, but it is not a substitute for a balanced eating plan. The data confirms that calcium supports bone mineralization, while magnesium aids neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as the building block for your bones and teeth, and magnesium as the relaxation mineral that helps your muscles and nerves function smoothly [NIH ODS]. Together, they work to maintain bone density and support proper nerve signaling. Zinc, also included, plays a supporting role in immune function and cell growth, though specific data on zinc from the provided information is limited.
Safety profile
Data not available for the exact number of adverse events for this specific product. However, for calcium supplements overall, FDA has received 592,059 total reports across all supplements. Specific side effects of high calcium intake include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [FDA data]. High intakes may also increase the risk of heart disease and prostate cancer [NIH ODS]. You should also know that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Our recommendation: take this supplement with food to improve absorption and reduce stomach upset. If you take thyroid medication or antibiotics, separate your doses by at least two hours [NIH ODS]. Do not exceed the labeled dose, as high calcium intakes carry real risks. For most adults, getting calcium from food sources is preferred, but this supplement can fill a gap when your diet falls short.
