How does bilberry extract protect the eyes?

The word "bilberry lutein ester" often appears in many eye nutrition products, but many people don't know much about it.

Bilberry lutein ester is actually mainly composed of bilberry extract and lutein ester. The common feature of these two eye protection ingredients is that they are very friendly to our eyes.

Bilberry extract is extracted from wild bilberry, which is rich in anthocyanins. For example, the anthocyanin content of European wild bilberry extract is 3-4 times that of blueberries.

Many eye diseases are ultimately attributed to free radical damage to the eye. Bilberry extract anthocyanin is a powerful antioxidant that can remove free radicals in the eyes, prevent free radical oxidation and protect eye health.

Lutein ester is a carotenoid fatty acid ester widely found in marigold flowers, pumpkins, cabbage, and other plants. Lutein esters can be converted into effective lutein in the human body.

In 2008, lutein ester was approved as a functional raw material of new resource food, which can be used in conjunction with bilberry extract to relieve eye fatigue more effectively.
