What Quercetin Is & Why It Matters
Quercetin is a plant-derived flavonoid that helps maintain normal inflammatory signaling and mast-cell stability. That translates to calmer skin surface feel and measured responses to everyday stimuli. It also supports redox balance by scavenging routine free radicals.
See the bigger picture in Polyphenols for Cats and Vitamin-Based Antioxidants for Cats, and anchor your research with the exact-match guide quercetin for cats.
Think “balance,” not “block.” Gentle modulation often feels better long-term.
Quercetin vs. Alternatives: How They Compare
- Resveratrol: Supports healthy aging pathways; see Resveratrol for Cats.
- Vitamin C: A water-soluble antioxidant that can recycle peers; read Vitamin C for Cats.
- Astaxanthin: Carotenoid support for eyes/skin; learn Astaxanthin for Cats.
- Glutathione: Master thiol antioxidant for redox balance; explore Glutathione for Cats.
Because each pathway covers different “gaps,” an all-in-one blend like Hollywood Elixir™ helps deliver broader coverage than a single compound alone.
