Can You Take L-Carnosine and Zinc Together?
May affect absorption
The short answer
L-Carnosine chelates zinc ions, which may reduce the bioavailability of supplemental zinc when taken simultaneously. Carnosine's histidine moiety has a high affinity for divalent metal cations.
How to arrange timing
Separate L-Carnosine and zinc supplements by at least 2 hours for optimal absorption of both.

Important context
Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
