Rutin in Retina Clear: What It Is and What the Research Says
Retina ClearA flavonoid found in buckwheat and citrus, tied to blood-vessel strength.
Retina ClearWhat it is
Rutin is a plant flavonoid found in buckwheat, apples and citrus peel. It is a glycoside of quercetin and is often described as a vessel-supporting flavonoid.
What research says
Most research on rutin is in the lab or in circulation and vein conditions. There are few well-controlled human studies on rutin for eye health, so its role in this kind of formula rests on plausibility more than on trials.
How Retina Clear uses it
Rutin is included in the Retina Clear blend. Since it is closely related to quercetin (also in the blend), you are getting two related flavonoids, but the label does not say how much of either.
Cautions: Generally well tolerated. Very high intakes may cause headache or stomach upset. It may add to the effect of blood thinners.
Quick answer
Why is rutin in an eye formula?
It is a flavonoid associated with healthy small vessels. Direct proof for the eye is limited.
