Synergy
What is happening. Quercetin has shown zinc-ionophore activity in cell models, but clinical immune benefit from combining quercetin with zinc is not established.
Mechanism. Cell studies suggest quercetin can transport zinc across membranes. Translation to meaningful antiviral or immune outcomes in humans has not been established.
Recommendation. Do not rely on quercetin plus zinc as antiviral treatment. Use only as general nutrition support and keep zinc within standard supplemental limits unless clinician-directed.
Stack Score
How this pair moves the number.
Effect on the composite score
If both Quercetin and Zinc are in the same stack, this pair applies +2 to your Stack Score (per scored synergy row).
The full algorithm, the clamping rules, and four worked stacks are documented at /methodology/stack-score.
