I have not experienced any
"I have not experienced any changes since taking the Quercetin. But I can rest easy knowing it is pure, clean, and doing what it is supposed to do. These are the purest products out there on the market."

Our plant-based Quercetin sets itself apart with its robust, enhanced formula that incorporates phytosome technology using sunflower lecithin, facilitating the delivery of active quercetin into cells. Unlike other supplements that contain synthetic and poorly absorbable ingredients, our advanced formula features Quercefit™, a patented, highly bioavailable, phospholipid form sourced from the flower buds of the Sophora Japonica plant. Leveraging Phytosome® technology, our unique compound enhances absorption by up to 20 times higher than standard quercetin products.
Quercetin's remarkable properties support a normal response to inflammation while regulating allergen response and histamine release. This makes it beneficial for managing allergic reactions, reducing symptoms like runny nose, watery eyes, and sneezing, and providing relief from seasonal allergies.
Quercetin supports immune system function through its antioxidant and anti-inflammatory effects. It helps regulate immune cell activity, modulates immune response, and enhances the body's defense against infections. By promoting a balanced immune system, quercetin may contribute to overall immune health and resilience.
Quercetin's anti-inflammatory properties can be particularly beneficial for respiratory health. It may help alleviate inflammation in the airways, reduce bronchial hyperresponsiveness, and support lung function. Additionally, quercetin's antioxidant activity may protect against oxidative damage in the respiratory system, making it a valuable compound for maintaining healthy respiratory function.
Quercefit™ is a patented, highly bioavailable form of quercetin sourced from Sophora Japonica flower buds.
I bought this quercetin and the liquid zinc supplement for my mother who has had terrible allergies for as long as I can remember. For the first time in many years, she finally has relief from her upper respiratory issues! Among other symptoms, she'll often develop a persistent cough, but as soon as she starts taking these two supplements together, it will subside. I'm so happy to have found a natural high quality solution for her!

Quercetin and turmeric are both antioxidants. While they may have mild blood-thinning properties, they offer different benefits and are not identical. Quercetin is excellent for supporting your immune and respiratory systems, and Turmeric is best used to ease your inflammatory response to help with joint health.
High servings of quercetin generally may affect the kidneys. If you are taking high servings greater than 1,000 mg daily for longer than two weeks, it is recommended to have periodic breaks from taking quercetin. If you have kidney disease, please check with your healthcare provider of choice before use in these delicate situations. Additionally, our product offers 250 mg of Quercefit (Quercetin from Sophora japonica extract/ Phospholipid lecithin from sunflower), and we recommend taking one capsule twice daily.
