The bilberry is a small deciduous shrub that grows chiefly in Europe.Its main components are anthocyanin.Anthocyanins are water-soluble pigments that occur naturally in a variety of foods, but are most abundant in dark fruits, such as bilberries.European bilberry extract anthocyanins are made up of five anthocyanins, which do not contain sugar groups and should be considered as degradation products of anthocyanins.

1. Protect eyes:Studies have shown that anthocyanins can help improve visual dysfunction caused by visual fatigue.Long-term use can significantly improve vision;Improved night vision and adaptability to darkness.In particular, in a clinical study, there were significant improvements in contrast sensitivity and visual acuity, resulting in significant improvements in visual quality.

2.Antioxidant activity: The most characteristic component of  bilberry fruit is polyphenols, which belong to anthocyanins and procyanidins.Its strong antioxidant activity can greatly promote the protection of blood vessels.Many studies have reported that European bilberry extract anthocyanins are powerful scavengers of free radicals such as superoxide anions and other reactive oxygen species (ROS).

3.Vascular health: The angioprotective effect of bilberry anthocyanins is related to its ability to reduce capillary permeability and improve capillary tolerance. Stimulating glycosaminoglycan synthesis is considered to be the key to vascular protection because glycosaminoglycan plays an important role in the physiological mechanisms of perivascular tissues.
