Start your day with the vibrant power of plants. Quercetin Phytosome delivers quercetin—a naturally occurring flavonoid that gives fruits and vegetables their rich colours—in a form designed for optimal absorption. Thorne’s advanced phytosome technology helps your body make the most of every capsule, so you can enjoy the benefits of this plant compound as part of your balanced lifestyle. Quercetin is a type of flavonoid, found in foods like apples, onions, berries, and tea, and is valued for its role in plant nutrition.

Because quercetin is naturally difficult for the body to absorb, Thorne’s Quercetin Phytosome uses a unique phytosome complex to enhance its bioavailability—making it up to 20 times more absorbable than standard quercetin extract. Enjoy a convenient way to add this plant-based ingredient to your daily routine.

Thorne’s Quercetin Phytosome has been third-party tested and certified to ensure the contents match the label and are free from unsafe levels of contaminants, including heavy metals, pesticides, and microorganisms. This added layer of quality assurance supports both transparency and safety. By taking this supplement, you can support your immune and respiratory health with confidence in its purity and effectiveness.
