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.

Found In

Apples, onions, berries

Supports

  • Immune function
  • Inflammation reduction
  • Allergy relief
  • Cardiovascular health
  • Muscle recovery

Best For

Dogs with allergies, skin issues, or high activity levels

Bonus Fact

Quercetin is often called “nature’s antihistamine” thanks to its ability to regulate histamine and soothe allergic responses

Rutin

Rutin is a powerful antioxidant flavonoid found in apples, citrus fruits, and buckwheat. It’s known for its ability to strengthen blood vessels and support healthy circulation, making it especially valuable for dogs with cardiovascular concerns or aging joints. By helping maintain flexible, resilient capillaries, Rutin may reduce swelling and discomfort in dogs with poor mobility or inflammatory issues.

This compound also supports a healthy inflammatory response, helping to manage stiffness and discomfort in dogs that are active, recovering, or simply aging. Rutin works well in combination with other flavonoids, making it a foundational compound in holistic wellness formulas.

In addition to cardiovascular support, Rutin has been studied for its ability to help stabilize histamines, similar to Quercetin. This may offer a second layer of allergy defense in sensitive pups.

Fisetin

Fisetin is a neuroprotective flavonoid most commonly found in strawberries, apples, and onions. It plays a key role in protecting brain cells, reducing oxidative stress, and supporting memory and learning. Fisetin has been studied for its potential to delay age-related cognitive decline, making it especially beneficial for senior dogs or those showing early signs of cognitive dysfunction.

Its antioxidant power also contributes to overall cellular health, helping to defend the body’s tissues—including the nervous system—from oxidative damage. Fisetin may also assist in regulating blood sugar levels and improving insulin sensitivity, making it a smart choice for dogs with metabolic or energy balance concerns.

Dogs of any age can benefit from Fisetin, but it's particularly helpful for aging companions who need support staying sharp, focused, and mentally engaged. It pairs well with other flavonoids for full-spectrum brain and body wellness.
