Quercefit™ boosts quercetin bioavailability by 20x.
This premium supplement harnesses the power of quercetin, a natural flavonoid found in various fruits and vegetables. This potent formula is expertly designed to support allergy relief, reduce inflammation, and boost immune function. Quercetin is especially renowned for its ability to modulate histamine reactions, offering significant benefits for those suffering from allergies and asthma.
Enhanced with Quercefit™ and Phytosome™ delivery technology, this product ensures maximum quercetin bioavailability and prolonged action over 12 hours. This advanced formulation delivers superior therapeutic benefits, promoting a healthier and more resilient body.
When investing in quercetin, proper formulation is crucial. Unformulated quercetin is poorly absorbed and quickly metabolised, requiring large and frequent doses to achieve any significant benefit. Natroceutics’ excels with its formulation featuring Quercefit™, a clinically proven and market-leading ingredient that enhances quercetin bioavailability by up to 20 times, maximising its effectiveness in the body. This product also utilises Phytosome™ delivery technology, which encapsulates quercetin molecules with food grade lecithin, ensuring prolonged action over 12 hours, enhancing its therapeutic potential. Supported by human clinical trials and ongoing research and development, this technology guarantees that your body derives maximum benefit.
