Flavonoid
Evidence-backed guides, research reviews, and health protocols covering Flavonoid.
Quercetin for Inflammation: Flavonoid Anti-Inflammatory
Quercetin is a powerful flavonoid found in onions, apples, and berries that fights inflammation through multiple pathways — inhibiting NF-κB, COX-2, and mast cell degranulation. This evidence-based guide covers quercetin's anti-inflammatory mechanisms, bioavailability challenges (and how phytosome solves them), optimal dosing, food sources, and safety.
Quercetin for Immune Health: The Antiviral Flavonoid
Quercetin is a plant flavonoid with potent antiviral and immune-modulating properties. Acting as a zinc ionophore, quercetin helps shuttle zinc into cells where it can inhibit viral replication. This evidence-based guide covers quercetin's immune mechanisms, bioavailability challenges, optimal dosing, and how to pair it with zinc for maximum antiviral support.
Fisetin for Longevity: Senolytic Flavonoid Guide
Fisetin is a plant flavonoid found in strawberries that emerged as one of the most potent natural senolytics—compounds that selectively kill zombie cells driving aging. This guide covers the science behind fisetin, how it clears senescent cells, clinical trial evidence, dosing protocols, bioavailability challenges, and practical supplementation advice.
Polyphenols for Gut Health: Complete Guide
Polyphenols are powerful plant compounds that act as prebiotics in your gut, feeding beneficial bacteria like *Bifidobacterium* and *Lactobacillus* while inhibiting harmful pathogens. This evidence-based guide explains the four main polyphenol classes, how your gut bacteria transform them into bioactive metabolites, and practical strategies to boost your daily intake for better digestive health.
