Natural Factors Zinc Citrate 50 mg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that Natural Factors Zinc Citrate 50 mg is a straightforward zinc supplement. However, the data provided does not contain specific information about zinc or this product. The data provided is for the ingredient calcium, not zinc. Therefore, we cannot assess zinc’s benefits or risks from this dataset. Data not available for zinc-specific effects.
How it works
Based on the data provided for calcium, this mineral supports bone density and mineral deposition, and it aids muscle relaxation and nerve signaling [NIH ODS]. This information does not apply to the zinc citrate product you asked about. For how zinc works, data is not available.
Safety profile
For the calcium data provided, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer. 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]. The FDA received a total of 592,059 adverse event reports across all supplements, but this number is not specific to zinc citrate [FDA data].
Our recommendation
Because the data provided is for calcium and not for Natural Factors Zinc Citrate 50 mg, we cannot make a recommendation on this specific product. We recommend you consult a healthcare provider for personalized advice on zinc supplementation. For the calcium data here, note that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
