Natural Factors Quercetin LipoMicel - Contains an advanced form of quercetin with 10 times higher absorption than standard forms. Quercetin is a bioflavonoid found in certain fruits, vegetables, herbs, and grains. It is used in herbal medicine to protect blood vessels, provide a source of antioxidants, and support immune function. It is also recognized for a range of other benefits, such as seasonal allergy relief and protecting against oxidative stress. Standard forms of quercetin can be difficult for the body to absorb and use effectively, which is the limiting factor in its clinical efficacy. Natural Factors unique patent-pending LipoMicel technology helps overcome this low bioavailability by creating a liquid micelle matrix that disperses quercetin into tiny micro-droplets. This superior delivery system is designed for enhanced absorption. Natural Factors Quercetin LipoMicel is a great choice for anyone suffering from conditions related to constricted blood vessels and adults who are looking for additional immune and antioxidant support.
