Bilberry
A fruit rich in antioxidants that is known for its ability to support eye health and vision.
Also known as: Vaccinium myrtillus
Overview
Bilberry (Vaccinium myrtillus) is a small, dark blue berry that is closely related to the blueberry. It has a long history of use in traditional medicine, particularly for its benefits to eye health. Bilberries are rich in anthocyanins, a type of flavonoid antioxidant that gives them their deep blue color. These anthocyanins are believed to be responsible for many of bilberry's health benefits, including its ability to improve vision, particularly night vision. The antioxidants in bilberry can help protect the eyes from damage caused by free radicals and may also improve blood flow to the retina. In addition to its benefits for eye health, bilberry has also been studied for its potential to improve cardiovascular health. The anthocyanins in bilberry can help lower blood pressure, reduce inflammation, and improve cholesterol levels. Bilberry may also have benefits for blood sugar control, as some studies have shown that it can help lower blood sugar levels in individuals with type 2 diabetes. Furthermore, the high antioxidant content of bilberry may have anti-cancer properties, although more research is needed in this area.
