Never miss a glorious update - click here!

Do your eyes feel tired and strained by the end of the day? Do you find yourself squinting more often than usual? If you answered “yes” to either of these questions, there’s a good chance you’re not alone.

Statistics show that the average American adult spends seven hours per day staring at a screen. If you get 8 hours of sleep, that’s nearly half of your day.

Luckily, there are ways to holistically support your eye health and prevent eye strain (without having to cut back on screen time). Bilberry, a berry native to Northern Europe, has gained popularity in recent years as a natural supplement for eye support. In addition to improving sight, it comes with other benefits that can improve your overall health.

This article deep dives into the health benefits of bilberry and reviews the 8 best Bilberry supplements on the market.

What is Bilberry?

Vaccinium myrtillus, European blueberries. Bilberries go by a few different names.

Bilberries are blue berries most commonly found in Northern Europe. But they can also be found in parts of Asia, Canada, and the Northern United States.

Their deep blue hue, benefits, and spelling make them very similar to blueberries.

However, there are a few unique features that set bilberries apart.

Bilberries have served medicinal purposes dating back to the Middle Ages. They have been used to treat anything from diarrhea and urinary infections to inflammation and diabetes. Today, bilberry extract is mostly used as a supplement to enhance eye function and support overall health. Its high antioxidant and vitamin C levels make it especially good for eye health.

Why Should You Take a Bilberry Supplement?

Let’s start with the obvious. Bilberries, like all fruits, are good for you. They are a rich source of vitamins C and K as well as antioxidants that help the body fight against diseases.

In particular, bilberries are an especially great source of anthocyanins, a flavonoid found in certain plants that contains anti-inflammatory, anti-cancer, and anti-diabetic properties. Most of the benefits bilberries provide are thanks to these high anthocyanin contents.

Now, here are a few specific benefits of bilberries, according to research.

1) Bilberries may improve your eye health.

The main appeal of bilberry supplements is their supposed effects on eye health.

While many people used to believe that bilberries could improve your night vision, recent research has shown this is not the case.

However, studies suggest that bilberry extract can help prevent eye fatigue, eye strain, and vision loss.

One study administered 120 mg of bilberry to participants with glaucoma, a condition that leads to sight loss, for two years. Participants who received the bilberry anthocyanins reported that their vision improved by 30%. The placebo group, on the other hand, reported that their symptoms worsened.

A different study showed that subjects who took bilberry extract daily reported less eye fatigue and dryness after screen time.

2) Bilberries may reduce inflammation.

The high anthocyanin content in bilberries may help reduce inflammation, a leading contributor to chronic disease.

One study showed that subjects who took bilberry supplements daily had significantly fewer markers of inflammation than the placebo group.

Another study produced similar results. In this trial, participants who drank bilberry fruit juice every day for a month had less inflammation than the placebo group.

3) Bilberries may lower blood sugar levels.

Berries are well-known for their ability to lower blood sugar levels. Some studies suggest that bilberries are especially effective at doing so.

For example, one animal study indicated that bilberries may encourage the release of insulin, which helps the body convert food into energy. Another study showed similar results, reporting that bilberries encouraged insulin release in adults at risk of diabetes.

A third study found that adults with type 2 diabetes who took 50 mg of bilberry extract reported lower blood sugar levels than the placebo group.

While these studies show promise, more research is needed to further support these claims.
