Bilberry refers to a small, dark blue fruit closely related to the blueberry, native to Europe and parts of Asia. It has been used for centuries in traditional medicine and as a food source, with its scientific name being Vaccinium myrtillus. The fruit is often consumed fresh, in jams, or as a dried supplement.
The most notable components of bilberry are its high concentration of anthocyanins, a type of antioxidant pigment that gives the fruit its deep color. These compounds are responsible for many of bilberry's reputed health benefits, particularly in supporting eye health. Traditionally, it has been associated with improving night vision and reducing eye strain, though modern evidence is still evolving.
Bilberry extracts are commonly found in supplements, where they are used to promote improved circulation and cardiovascular health. The antioxidants may help protect blood vessels and reduce inflammation. Additionally, bilberry is sometimes taken to support digestive health and as a general antioxidant to combat free radicals in the body.
As a supplement, bilberry is typically available in capsule, tablet, or liquid extract forms. The fruit itself can be eaten or made into teas. While generally considered safe for most people, it may interact with certain medications, such as blood thinners, due to its potential effects on blood clotting. The most beneficial applications are often linked to its antioxidant properties and traditional uses for vision and circulation support.
