Sundown Naturals Zinc 50 mg
Brand: Sundown Naturals · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Sundown Naturals Zinc 50 mg provides a significant dose of zinc, but the data provided is for calcium, not zinc. Based on the data available, we cannot assess this specific product's benefits or risks. For calcium, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should know that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, and it also helps your muscles relax and nerves signal properly [NIH ODS]. This mechanism is well-documented for calcium, but for zinc, data is not available in this report.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high levels 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For zinc side effects, data is not available.
Our recommendation
We recommend you consult your healthcare provider before starting this supplement, as the data provided does not cover zinc specifically. If you are taking any medications, be aware that calcium supplements may interfere with their absorption [NIH ODS]. Start only under professional guidance, and do not exceed the recommended dose on the label. For a full risk assessment of zinc, data is not available in this report.
