Blueberries (Vaccinium myrtillus) are rich in bioactive plant compounds, as well as provitamin A, vitamin B2, and zinc. Pure Encapsulations' blueberry extract contains 80 mg of fruit extract standardized to 25% anthocyanosides per capsule. Like all Pure Encapsulations' plant extracts, blueberry extract is also tested for 70 different pesticides, among other things. This guarantees the product is free of pesticide residues.
 Anthocyanosides help reduce inflammatory reactions and oxidative stress in the intestines associated with excess fat and carbohydrate consumption, and improve intestinal barrier function. Due to their pronounced antioxidant and vasoprotective effects, anthocyanosides are of particular interest to ophthalmologists, as they accelerate retinal regeneration, resulting in improved retinal sensitivity to various levels of light radiation and improved visual acuity.
