Full Spectrum Vitamin E May Help Support Eye Health in Diabetics
Diabetes can lead to eye health problems when high blood sugar levels cause damage to the blood vessels in the retina. This is called diabetic retinopathy. According to a recent study, supplementation with full spectrum vitamin E, which provides tocotrienols and alpha tocopherol, may help improve early-stage diabetic retinopathy.
30 adults with Type II diabetes and early-stage diabetic retinopathy participated in the study. They received 400 mg of full spectrum vitamin E from red palm oil, or a placebo daily for 12 weeks. The researchers evaluated bleeding in the retina, known as retinal microhemorrhages, at baseline and at the end of the study period. They also measured the amount of fluid leaking from blood vessels into the macula, which can cause vision loss.
Participants in the full spectrum vitamin E group saw a 41.9% decrease in the number of retinal microhemorrhages, compared to an 18.4% decrease in the placebo group.
Participants in the full spectrum vitamin E group also experienced a 48.9% decrease in diabetic macular edema (DME), which occur when blood vessels leak fluid into the macula, compared to a 25.1% increase in the placebo group.
The study was conducted by researchers from Monash University Malaysia. It was published online ahead of print on May 23, 2021 in the International Journal of Diabetes and Clinical Research.
