Bilberry: the Good, the Bad, and the European!

As a company founded on science, EyePromise works hard to follow the latest published articles regarding eye health. Additionally, we strive to continually update and upgrade our products to help those who use them get the very best eye health outcomes. With this, EyePromise has decided to update our Screen Shield™ Pro formulation, removing optiberry and adding more bilberry extract. Here’s why.

What Is Bilberry?

Also known as whortleberry, huckleberry, or European blueberries, bilberries are fruit that grow on small shrubs in Northern Europe like the UK and Ireland. These berries have a much more acidic profile than their American cousins, and they were often used to dye linens and clothing. Bilberries are rich in antioxidants and have been used for a number of medicinal purposes since the Middle Ages.

Benefits of Bilberries

Like many foods with antioxidant properties, bilberry is often used to help relieve inflammation throughout the body, including the legs, throat, and eyes. Other reasons people may use bilberry include:

  • Improving circulation
  • Strengthening blood vessels
  • Support heart health
  • Promote healthy brain function
  • Boost immune health
  • Support healthy eyes, including relieving eye strain related to screen time

In one study, bilberry, in combination with lutein and Omega-3s, helped relieve eye strain as well as mental fatigue after 4 weeks. Another study demonstrated that bilberry supplementation relieved eye fatigue both subjectively and objectively.

Side Effects of Using Bilberry

Bilberries are typically considered safe for consumption, but what about the fruit extracts? Science says that these extracts are typically safe, as well, when taken in the right amounts. The risk increases when using bilberry leaves in high doses for a long period of time. Some possible negative side effects could include:

  • Increased risk of bleeding if on blood thinners
  • Possible interaction with diabetes medications

There has also been little testing that includes children or pregnant women, so it’s best to confer with a physician before adding it to your regimen.

Where Can I Get Bilberries?

You can find bilberries fresh, frozen, dried, powdered, or in preserves like jam, while bilberry leaves are often made into teas. However, they are not as readily found in your typical grocer as blueberries, and they often cost a pretty penny more. As for supplements and extracts, you can find them in softgels, tablets, capsules, and drops.

It’s important to read the labels of the supplements purchased and do your due diligence for researching the company that makes it. The National Institutes of Health (NIH) recommend finding a product that is third-party tested by the USP or NSF, as well as one that follows the FDA cGMP guidelines.
