Bilberry Extract is usually dark purple or dark red powder, and its main active ingredient is anthocyanin. Anthocyanin is a powerful antioxidant that has a wide range of health benefits, especially in eye health. Bilberry extract is often used in health products and food supplements due to its rich anthocyanin content, especially in products targeting eye health. An important function of bilberry extract is to improve eye health. Anthocyanin can enhance blood flow to the retina, promote oxygen and nutrient supply to eye tissues, and thus improve visual function. It can also improve night vision and make the eyes adapt faster in dark environments, which is especially helpful for those who need to work or move in low light conditions. By enhancing the health of the retina, bilberry extract can slow down age-related vision loss and help prevent eye-related diseases such as macular degeneration and optic atrophy.

In addition, the antioxidant properties of bilberry extract also have a positive impact on systemic health. It can neutralize free radicals in the body, slow down the cell aging process, and reduce the risk of chronic diseases. Studies have shown that antioxidants such as anthocyanins can enhance the body's immune system, improve resistance, and help prevent and alleviate various diseases. Bilberry extract also has anti-inflammatory properties, which can help reduce inflammation in the body and further promote overall health.
