Grape Seed Extract in Retina Clear: What It Is and What the Research Says
Retina ClearA polyphenol-rich extract used as an antioxidant in many formulas.
Retina ClearWhat it is
Grape seed extract is made from the seeds left over from winemaking. Its main compounds are oligomeric proanthocyanidins (OPCs).
What research says
Some small studies have looked at grape seed extract for eye fatigue after screen work and for diabetic retinopathy markers, with mixed or preliminary results. Most lab data are on cells, not on people's eyes.
How Retina Clear uses it
Retina Clear puts grape seed extract in the blend without naming the amount or OPC percentage, so its potential dose cannot be compared to studies.
Cautions: Generally well tolerated in short-term use. It may add to the effect of blood thinners, so mention it to your pharmacist if you use them.
