Viva Vitamins Super Zinc 50 mg
Brand: Viva Vitamins · Form: TABLET [E0155] On Market
Our assessment
Our assessment: For most people, 50 mg of zinc is a high daily dose that exceeds the recommended dietary allowance. The data shows the RDA for zinc is 11 mg for men and 8 mg for women, and the tolerable upper intake level is 40 mg per day for adults [NIH ODS]. Taking 50 mg daily, as in this product, puts you above that safe upper limit, which increases your risk of side effects. We generally recommend you do not take this product without first consulting a healthcare provider.
How it works
Zinc is an essential mineral that supports your immune system, helps with wound healing, and is needed for cell growth and division [NIH ODS]. It acts as a critical cofactor for over 100 enzymes in your body. However, the body tightly regulates zinc levels, and taking more than needed can disrupt its balance with other minerals like copper [NIH ODS].
Safety profile
Safety data from the FDA shows that adverse events are reported for zinc supplements. The FDA has received 2,213 adverse event reports for zinc products [FDA data]. Common side effects from taking too much zinc include nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches [NIH ODS]. Long-term use of high doses, such as 50 mg daily, can also lead to copper deficiency, which may cause neurological problems and anemia [NIH ODS].
Our recommendation
Our recommendation: Do not take this supplement unless a doctor has confirmed you have a zinc deficiency or a specific medical need for such a high dose. For general immune support, a standard multivitamin or a lower-dose zinc supplement (15-25 mg) is safer and more appropriate. If you choose to take this product, limit use to short-term (a few weeks) and be aware of the risk for copper deficiency [NIH ODS] [FDA data].
