Can an oral prebiotic and arginine supplement improve hay fever? Original paper
In this randomized controlled trial, a prebiotic lozenge containing arginine improved symptoms of hayfever after 14 days, but not after 21 days. However, important methodological limitations and a large conflict of interest reduce our confidence in these findings.

Quick Summary
In this randomized controlled trial, a prebiotic lozenge containing arginine improved symptoms of hayfever after 14 days, but not after 21 days. However, important methodological limitations and a large conflict of interest reduce our confidence in these findings.
What was studied?
The effect of oral supplementation with arginine-containing prebiotics on allergic rhinitis (hay fever).
The primary outcomes measured were changes in total nasal symptoms score (TNSS; total score, and 3 subdomains) and peak nasal inspiratory flow (PNIF). The secondary outcomes were changes in oral microbiota as measured by saliva testing. Total immunoglobulin E, eosinophil count, heart rate, blood pressure, and body temperature were measured as safety parameters, in addition to adverse events.
