Can I Take vitamin c and zinc Together?

SUMMARY:

There are no clinically significant interactions between vitamin C and zinc when taken together at typical supplemental doses; they are generally considered safe to use concomitantly. Monitor for side effects from high doses (gastrointestinal upset, long‑term zinc can cause copper deficiency) and discuss dosing with your healthcare provider.

ADDITIONAL NOTES:

Both are dietary supplements (vitamin/mineral). No major pharmacokinetic or pharmacodynamic interactions are expected at usual doses. High-dose zinc may cause nausea, vomiting, metallic taste, and with chronic high intake can cause copper deficiency and anemia; intranasal zinc has been associated with loss of smell. High-dose vitamin C can cause GI upset and may increase oxalate excretion (risk for kidney stones in susceptible individuals) and increases iron absorption (caution in hemochromatosis). If you take other prescription medications or have chronic conditions, check with a clinician or pharmacist.
