Value pack of 2. Brain and Nervous System Health Luteolin And Rutin Dietary Supplement Vegan For the latest in antioxidant protection from a blend of bioflavonoids, try Swanson Luteolin Complex. Flavonoids (or bioflavonoids) are plant-derived nutrients that show great promise for promoting overall well-being. Luteolin has been widely studied for potential benefits for human heart and brain health, cognition, longevity and more. Mitochondria (the energy center of every cell) function, or rather the decline thereof, is believed to be a primary cause of aging. This "mitochondrial theory of aging" is closely tied to the "free radical theory" in that free radicals are produced within cells by the energy-producing function of the mitochondria. A number of reports suggest that luteolin may defend against mitochondrial aging by activating these cellular antioxidants. This free-radical defense may extend to the brain as well, making it a unique product for cognitive nourishment and support. Emerging research also supports the traditional use of luteolin in support of cardiovascular health again thanks to its flavonoid antioxidant content. Additionally, luteolin contributes to metabolic health by acting as an inhibitor of DPP-IV (dipeptidyl-peptidase-4), an enzyme that is a factor in the breakdown of the GLP-1 hormone. GLP-1 is currently at the forefront of weight management attention. It’s also important to note that not all luteolin supplements are equal. Luteolin is not bioavailable on its own. It requires the presence of other bioflavonoids in order to be metabolized the body and reach the cells in active form. Luteolin is often accompanied by rutin, which "unlocks" its potential to promote human health. Swanson Luteolin Complex delivers pure, natural luteolin and rutin in perfect balance for optimal biological benefit.
