Lipo-flavonoid

Lipo-flavonoid (also Lipo-flavonoid Plus) is a dietary supplement created in 1961 by Smith, Miller, and Patch, which is marketed on the Internet and in television commercials. The manufacturer, Clarion Brands, claims that it improves circulation in the inner ear, as a means of combating tinnitus (ringing in the ears).

Lipo-flavonoid has not been approved by the FDA to diagnose, treat, cure, or prevent any disease. There is no good evidence that it is effective against Meniere's disease, hearing loss, or tinnitus. There have not been any random controlled trials of Lipo-flavonoid for any purpose in the medical literature.

Lipo-flavonoid is a concentrated extract of lemon peel. It is composed principally of ascorbic acid (vitamin C), eriodictyol glycoside also called eriocitrin (lemon flavonoid, a natural yellow food coloring found in lemon peel), choline, and inositol. It also contains a small amount of B vitamins (B₆, B₁₂, niacin, riboflavin, thiamine, and pantothenic acid) and methionine.
