Quercetin is a powerful plant-based flavonoid rich in antioxidants. During an allergic reaction the body releases histamine. Histamine contributes to inflammation, redness and irritation. Research has shown that Quercetin can “turn off” histamine production and suppress, or at least moderate, inflammation. For this reason, many have coined it “Nature’s Benadryl”. Furthermore, Quercetin helps suppress cellular activity associated with inflammation. This means less itching!
It also inhibits the production of specific inflammatory molecules. This is exciting because Quercetin is actually helpful in treating asthma and respiratory issues involving inflammation. Bronchial tubes in the lungs become restricted during an asthma attack (bronchoconstriction). Medical studies show that Quercetin can actually minimize the amount of constriction!

Recommended Dosage:
The dosage for Quercetin supplements is often provided for humans weighing approximately 150 pounds and is around 1000mg. Here’s how to convert the dosage for your pet:
Take the weight of your pet and multiply it by 1000mg, then divide it by 150 to get the milligram dosage your pet needs.
70-pound Shepherd as an example: (70lb x 1,000mg= 70,000 then divide by 150 = 466 mg).
The recommended dosage is 466mg all day. Rounding that to the closest whole number, the dosage would be 500mg per day (best if split in half, meaning one 250mg dosages twice a day).
