There is scientific evidence that bilberries and bilberry extract have health benefits beyond just the best-known effect on eye health.

♦ BILBERRY improves circulation and helps lower LDL cholesterol
♦ BILBERRY helps contribute to vision health
♦ BILBERRY may ‘significantly’ slow the accumulation of two beta amyloid peptides that are the ‘hallmark’ of Alzeimer’s

The health benefits of bilberries, according to, include improved blood vessel integrity and circulation, lowered blood glucose levels, a protection against cell damage and possibly improved vision health via retinal protection – especially in cases of diabetes.

Bilberries are in the same plant family as blueberries, with the former found wild in Europe, while the latter are cultivated in North America. Their health benefits are due to their high content of the bio-actives called anthocyanins or anthocyanidins. These are powerful anti-oxidant and anti-inflammatory flavonoids and help counteract the damaging effect of excess free radicals.

The National Centre for Biotechnology Information has a whole chapter on bilberry and states that:

“Bilberry is of potential value in the treatment or prevention of conditions associated with inflammation, dyslipidemia (high blood fat levels), hyperglycemia (high blood sugar levels) or increased oxidative stress, cardiovascular disease (CVD), cancer, diabetes, dementia and other age-related diseases”.

The same chapter also identified the ability of bilberries and bilberry extract to positively affect DNA repair and gene expression. So they should be considered as part of an anti-cancer nutritional regime, which would also include carotenoids like lycopene and lutein, vitamins D3, folic acid and K2, Omega 3, soy isoflavones, green tea extract and the minerals selenium and boron.

1. Bilberry for vision health

Bilberry for more than just eye health NutriShield Multi Vitamins and MineralsAlthough the research is not conclusive, there is enough evidence to consider bilberry in cases of retinal damage to the eye and – in combination with lutein, zinc and omega 3 – in cases of macular degeneration and cataracts. It may help low light vision.

2. Bilberry for improved circulation and heart health

It must withstand the pressure of the constant expansion and contraction as the heat beats.

A study in The American Association of Clinical Chemistry showed that Bilberry extract has been found to significantly improve endothelial health and blood flow in humans – accompanied by beneficial reduced blood fat levels and inflammation.

A further animal study in Review of Diabetic Studies showed that bilberry reduces LDL cholesterol (the ‘bad’ kind) and overall cholesterol.

3. Bilberry protects the brain
