Quercetin
Quercetin is a powerful antioxidant and anti-inflammatory compound found in apples, onions, and berries. It helps neutralize free radicals that cause oxidative stress, which can lead to chronic inflammation and cellular damage over time.
This flavonoid is especially beneficial for dogs with allergies, sensitivities, or immune-related issues. Quercetin supports the immune system’s natural defenses and may help regulate histamine responses that cause itching, redness, or hot spots. It also promotes healthy circulation and may contribute to maintaining stable blood pressure.
In active dogs, Quercetin can support faster recovery by reducing muscle soreness and supporting joint flexibility. Whether your dog is aging, highly active, or just prone to seasonal allergies, Quercetin delivers daily protection that keeps them feeling balanced and resilient.
