grapefruit and orange are all excellent sources of rutin


Most foods do not contain rutin in therapeutic doses, and the amount of rutin in each food can vary widely depending on soil type and the genetic structure of the plant. Still, fruits and vegetables are highly absorbable sources of natural rutin. Citrus fruits like lemon, lime, grapefruit and orange are all excellent sources of rutin, which is most highly concentrated in the rind.
