Separate doses by at least 2 hours. Take zinc carnosine with breakfast or lunch and magnesium L-threonate in the evening. Do not take both simultaneously on an empty stomach.
Why this interaction occurs
Divalent cations including magnesium (Mg²⁺) and zinc (Zn²⁺) compete for shared intestinal transporters, particularly ZIP and DMT1 transport proteins. High-dose concurrent intake can reduce bioavailability of both minerals. Zinc carnosine's delayed-release nature partially mitigates this, but separation remains advisable to optimize absorption of each.
Evidence
Evidence level: strong.
