Manuka Honey (Food) for Immune Function

Research on Manuka honey specifically for immune function is extremely limited in the available evidence base, with only a single industry-funded laboratory study identified here — and notably, that study did not directly examine Manuka honey's effects on immune function at all. The study investigated inflammatory mechanisms related to sore throat using human respiratory cell and tissue models, and while it touched on how certain compounds affect inflammatory markers like PGE2 and IL-8, its primary focus was on a proprietary formula called Biovanta rather than Manuka honey. It is worth noting that the study was entirely funded by the company that manufactures and sells Biovanta, with all authors listed as company employees, which represents a significant conflict of interest. Overall, the currently linked evidence is insufficient to draw any meaningful conclusions about Manuka honey's effects on immune function, and readers interested in this topic should seek out independent, peer-reviewed research specifically designed to evaluate Manuka honey.
