nutriana Zinc 450 mg
Brand: nutriana · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that this product provides a very high dose of zinc. The FDA data indicates that the Tolerable Upper Intake Level (UL) for zinc is 40 mg per day for adults [FDA data]. Our assessment is that a 450 mg dose far exceeds this established upper limit and poses a significant risk of toxicity. We cannot recommend this product for daily use.
How it works
Zinc is an essential mineral that supports immune function, wound healing, and cell growth [NIH ODS]. It acts as a cofactor for hundreds of enzymes in the body [NIH ODS]. However, the dose in this product is not supported by any standard clinical guidelines for supplementation.
Safety profile
Data not available on specific adverse event reports for this brand. However, the FDA data clearly states that taking high doses of zinc can cause copper deficiency, which can lead to neurological issues and anemia [FDA data]. Other side effects of excessive zinc intake include nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches [NIH ODS]. The 450 mg dose in this product is dangerously high.
Our recommendation
Our recommendation is to avoid this product. The 450 mg dose is not safe for daily consumption. For general health, the RDA for zinc is 11 mg for men and 8 mg for women [NIH ODS]. If you are considering zinc supplementation, choose a product that provides no more than the Tolerable Upper Intake Level of 40 mg per day, and only after consulting with your healthcare provider [FDA data] [NIH ODS].
