1. Improved Vision
Due to the anthocyanosides, Bilberry Extract is widely used to improve night vision or vision handicaps in low light, decreasing vascular permeability and capillary fragility. It was reported that during World War II, British fighter pilots had improved nighttime vision after eating bilberry jam.
Bilberry has been suggested as a treatment for retinopathy, which is damage to the retina. Bilberry has also exhibited protective effects against and macular degeneration, glaucoma and cataracts.
2. Helps Eliminate Circulation Problems
In Europe, health care professionals use bilberry extracts to treat circulation problems, also known as chronic venous insufficiency (CVI). Research suggests that this condition, which occurs when valves in veins in the legs that carry blood to the heart are damaged, may be improved by taking bilberry extract. Other research suggests that taking bilberry anthocyanins daily for up to six months might improve swelling, pain, bruising and burning associated with CVI.
3. Improve Bad Cholesterol
The amazing proanthocyanosides found in bilberries may strengthen blood vessels and prevent the oxidation of LDL (“bad”) cholesterol, a major risk factor for atherosclerosis that is the plaque that blocks blood vessels leading to heart attack and stroke.
4. May Improve the Blood Sugar in Diabetics
Traditionally, bilberry leaves have been used to control blood sugar levels in people with diabetes. Research shows that most berries help reduce the body’s glucose response after eating a high-sugar meal and studies suggest bilberry may be effective for managing blood sugar levels, particularly when combined with oatmeal, though more research is needed.
