What Is PHLORETIN?
Phloretin is a natural dihydrochalcone flavonoid found primarily in apples and apple tree bark that exhibits anti-inflammatory, antioxidant, and neuroprotective properties. It works by modulating multiple signaling pathways including NF-κB and Nrf2, trapping reactive dicarbonyl species, and inhibiting specific ion channels and glucose transporters. Research suggests potential benefits for cognitive function, inflammation reduction, and cellular protection against oxidative stress.

01 The Molecular Pharmacology of Phloretin: Anti-Inflammatory Mechanisms of Action ▸
Comprehensive review detailing phloretin's anti-inflammatory mechanisms through inhibition of cytokine signaling pathways, suppression of COX and iNOS, and protective effects in multiple organ systems including cardiovascular, hepatic, renal, and nervous tissue.
View Study (PubMed)02 Nootropic, neuroprotective and neurotrophic effects of phloretin in scopolamine induced amnesia in mice ▸
In vitro and animal studies demonstrated that phloretin significantly influences neuronal membrane fluidity and potential, decreased excitotoxicity, and showed nootropic and neuroprotective effects in scopolamine-induced amnesia models.
View Study (PubMed)03 Apple Polyphenols, Phloretin and Phloridzin: New Trapping Agents of Reactive Dicarbonyl Species ▸
Research identified phloretin as an effective trapping agent for reactive dicarbonyl species, providing antioxidant protection that may contribute to preventing oxidative stress-related diseases and cellular damage.
View Study (PubMed)04 Effects of Phloretin and Phloridzin on Ca2+ Handling, the Action Potential, and Ion Currents in Rat Ventricular Myocytes ▸
Study revealed that phloretin affects cardiac cellular function by modulating calcium handling, inhibiting transient outward potassium currents, and increasing action potential duration in ventricular myocytes.
