What to know before you buy bilberry extract

What bilberry extract is

Bilberry extract is made with bilberry fruit and leaves, and used for medicinal purposes. The plant’s chemicals include nutrients and antioxidants. The fruit is also used to make jams and sauces.

How bilberry extract works

Health benefits of bilberry extract 

Bilberries are nutrient-rich, antioxidant-rich and help combat a variety of health issues. They are a great source of water, fiber, vitamin C, vitamin K and manganese. They are similar to blueberries in their beneficial properties and are a great source of anthocyanins. Anthocyanins give the bilberry its color and have anti-cancer and anti-inflammatory properties.

  • Promote eye health. The anthocyanins in bilberries improve vision, reduce eye irritation, dryness and eye fatigue.
  • Reduce inflammation. The tannins naturally found in bilberries reduce swelling. Swelling, or inflammation, may lead to disease. Anthocyanins help to reduce and prevent inflammation. If you suffer from ulcerative colitis, bilberry extract may help reduce colon inflammation and lessen symptoms.
  • Lower blood sugar levels. Bilberries lower blood sugar levels by curbing your body’s absorption of carbohydrates. High blood sugar leads to hyperglycemia in patients with diabetes, says the Mayo Clinic. Anthocyanins may also promote insulin secretion. Insulin transports sugar from your blood to your cells and helps lower blood sugar levels.
  • Improve heart health. Bilberries are rich in vitamin K. Vitamin K helps prevent blood clots, which reduces the risk of stroke and heart attack. They may also help lower cholesterol and blood pressure.
  • Fight free radicals. The antioxidants in bilberries combat the free radicals that cause disease. 
  • Improve brain function. The nutrients and antioxidants in bilberries may improve long-term memory.

  • Hair growth. Bilberries may stimulate hair growth. They promote circulation, which supports blood flow to your hair follicles. This means stronger, healthier hair.
