How it works
Zinc works as a critical cofactor for over 300 enzymes in your body. It supports your immune system by helping white blood cells function properly and aids in wound healing by supporting collagen synthesis. Zinc also plays a role in DNA synthesis and cell division, making it essential for growth and development [NIH ODS].
Safety profile
The safety profile for zinc supplements includes potential side effects such as nausea, vomiting, and stomach cramps when taken in excess. High doses can lead to copper deficiency, which may cause anemia and neurological issues.

Our recommendation
Our recommendation: You should follow the dosage on the label and avoid exceeding the tolerable upper intake level of 40 mg per day for adults. Take zinc with food to reduce stomach upset. If you take antibiotics like tetracycline or fluoroquinolones, separate your zinc dose by at least 2 hours to avoid absorption interference [NIH ODS].
