Yes — the classic cold-season combo is safe to take together; the thing to watch is your zinc total, not the pairing.

Yes — the classic cold-season combo is safe to take together; the thing to watch is your zinc total, not the pairing. Vitamin C is typically taken for antioxidant, immune support, collagen synthesis, while Zinc is used for immune function, wound healing, taste & smell — different jobs, so people often end up with both in the cabinet.
For context: a typical daily amount of Vitamin C is 75–90 mg, and the upper limit for Vitamin C is 2,000 mg. A typical daily amount of Zinc is 8–11 mg, and the upper limit for Zinc is 40 mg.
