Rutin, a flavonoid from apples, citrus, and buckwheat, works as an antioxidant. It helps strengthen capillaries and supports blood flow.
Take rutin as a capsule or powder, with a meal for best absorption. Some people use it for chronic venous insufficiency, though this is not FDA-approved.
Rutin can interact with blood thinners. If you take anticoagulants or have a bleeding disorder, check with your doctor before use. Its safety in pregnancy and breastfeeding is not established.
