It’s possible to overconsume either nutrient if you exceed the recommended upper limits. Too much vitamin C can cause gastrointestinal discomfort, including diarrhea, nausea, and abdominal cramps.

Peter Hunt, Director & Physiotherapist at The Alignment Studio, explains,
Zinc can interfere with the absorption of copper and iron if taken in excess or at the same time. On the other hand, taking vitamin C with zinc is generally safe and often beneficial. Vitamin C can enhance the immune-supporting properties of zinc, making this combination common in cold and flu prevention supplements.
However, taking these together on an empty stomach can sometimes cause mild side effects like nausea or stomach upset. As for the brand of supplements, quality matters. Cheaper brands may use forms of zinc or vitamin C that are harder to absorb or contain unnecessary additives, so choosing reputable brands ensures both safety and efficacy.
