Bilberry fruit extract is a concentrated form of the fruit, standardized for anthocyanins. These flavonoid pigments act as antioxidants and support the health of tiny blood vessels, especially in the eyes and microcirculation.
Many people take bilberry extract to support visual function and ease eye strain from computer use or fatigue. Others use it to maintain circulation and capillary strength. Standardized extract is favored over whole powder because it delivers a consistent level of active compounds.
Dosing depends on the extract's concentration. A typical routine is once or twice a day. Standardized extracts with 25% anthocyanosides are common. Take it with a meal that includes some fat for better absorption. Most people tolerate bilberry extract well. If you have diabetes or take medication, monitor your blood sugar. High doses can interfere with blood clotting.
