Multi-Component Supplement May Help Diabetics Eye Health
People suffering from diabetes often develop problems with their vision as the illness progresses. A recent study suggests that taking a multi-component supplement specially formulated for eye health may improve contrast sensitivity, color vision, and macular pigment optical density in people with type-1 or type-2 diabetes.
Participants in the study included 67 people with diabetes who were given either two softgels of the supplement or a placebo daily for six months. The supplements contained vitamins C, D3 and E, zinc oxide, EPA, DHA, alpha-lipoic acid, CoQ10, mixed tocotrienols/tocopherols, zeaxanthin, lutein, benfotiamine, NAC, grape seed extract, resveratrol, curcumin, green tea leaf, and Pycnogenol.
At the conclusion of the study, the supplement group had a 28% improvement in contrast sensitivity, a 42% improvement in color vision, and a 27% improvement in macular pigment optical density. They also had improvements in serum lipids and high-sensitivity CRP, which is a marker of inflammation.
The researchers did not note significant differences between the two groups for retinal thickness, HbA1c, or total cholesterol.
Researchers from Captain James A Lovell Federal Health Care Center in Chicago conducted the study. It was published online ahead of print on June 18, 2015, in the British Journal of Ophthalmology.
Previous studies suggest that all of the vitamins and supplements included in this study do, in fact, help with vision. Lutein and zeaxanthin as well as omega-3s in particular have been found to improve macular pigment optical density and slow the advancement of age-related macular degeneration.
