Rutin

Rutin is a plant-derived flavonoid glycoside, commonly found in foods like buckwheat, apples, citrus fruits, and tea. It is recognized for its potent antioxidant capacity, helping to neutralize free radicals and support overall cellular health. In supplement formulations, rutin is frequently used to promote healthy circulation and to aid in the maintenance of blood vessel integrity, which can be particularly relevant for eye health due to the delicate vasculature of the retina. Manufacturers usually source rutin from buckwheat or Japanese pagoda tree flowers (Sophora japonica). It is prized for its potential roles in supporting the body's response to oxidative stress and maintaining capillary function. When checking supplement labels, rutin may be listed as “rutin extract” or “quercetin-3-O-rutinoside.” Its inclusion in multi-ingredient blends, especially those aimed at vision or cardiovascular health, is common due to its supportive properties and well-documented safety profile.
