Oxerutins are a group of chemicals derived from a naturally occurring bioflavonoid called rutin.

This supplement has been widely used in Europe since the mid-1960s, as a treatment for conditions in which blood or lymph vessels leak fluid. Considerable evidence suggests that oxerutins are effective. Unfortunately, it is difficult to find this supplement in North America.

Although they are closely related to a natural flavonoid, oxerutins are not found in food. The only way to take them is in a supplement.
