What are the benefits of bilberry extract?

The following benefits have been observed from research studies into bilberries, bilberry extract or anthocyanosides:

  • Strengthens blood vessels
  • Improves circulation
  • Treats diarrhoea
  • Prevent cell damage
  • Could help in treating retinopathy
  • May help lower blood glucose levels

Bilberry extract and retinopathy

Retinopathy and maculopathy are both conditions of the retina in the eye that are more likely to develop in people with diabetes.

Research has shown that people with retinopathy that took bilberry extract during the study showed signs of strengthening of blood vessels in the retina and reduced haemorrhaging.

The research that has been carried out to date has been small scale and so whilst bilberry extract shows promise, researchers are yet to find out how much bilberry extract may be of help in limiting the development of retinopathy.

Bilberries and lower blood glucose levels

Bilberry extract is not recognised as a treatment for diabetes but people with diabetes may notice that it helps in lowering blood glucose levels.

If you are on blood glucose lowering medication that can bring on hypoglycemia, you may need to monitor your blood glucose levels and take precautions to ensure blood sugar levels don’t go too low.

Bilberries and heart health

The National Institutes of Health in the United States notes that there is evidence to suggest that bilberry extract could help lower blood sugar and blood cholesterol levels. Animal studies indicate that anthocyanosides may prevent oxidation of LDL cholesterol which plays a role in atherosclerosis and heart disease.

Anthocyanosides are also recognised as being helpful for improving circulation and reducing the risk of blood clots forming.

How can bilberry extract be taken?

Bilberry extract can be taken in supplement form, often as tablets or capsules. Bilberries can be eaten, in fresh or dried forms, or drank as bilberry tea or as a smoothie.

It is advisable to check with your doctor before taking any new supplements.
