Bilberry and Pine Bark Nutrients Are Valuable For Supporting Eye Health
Research Demonstrates How Specific Antioxidants, Carotenoids, Phytochemicals Including Bilberry and
Pine Bark Are Valuable For Supporting Eye Health
Daily supplements of a Bilberry extract and an extract from French maritime Pine Bark may lower the pressure in the eye and boost overall ocular health, says a new study.
High blood pressure in the eye, known as ocular hypertension, was reduced following 24 weeks of supplementation with the according to findings published in Clinical Ophthalmology.
Furthermore, when the ingredient mix was used in combination with Latanoprost eye drops, the pressure in the eye was reduced to almost normal levels, report the researchers from the University of Chieti-Pescara in Italy.
“Ocular hypertension is not only a major contributor to impaired vision, but can result in serious health challenges including glaucoma, a condition that affects nearly 2.5 million U.S. adults,” explained the researchers. Supporting previous studies, this new research further demonstrates that specific antioxidants, carotenoids and phytochemicals are effective, natural solution for improving blood flow through the central retinal arteries.
Between 4 and 7 per cent of the US population is estimated to have ocular hypertension, according to a report published in the Archives of Ophthalmology earlier this year. The condition is reported to increase the risk of developing glaucoma, but not all cases of ocular hypertension lead to glaucoma
The researchers recruited 79 people with ocular hypertension but no signs of visual loss or glaucoma, and randomly assigned them to one of three groups: One group received daily Bilberry and Pine Bark supplements one group received Latanoprost eye drops, and the third group received a combination of both.After 24 weeks of intervention, the researchers noted a reduction of blood pressure in the eye.
Commenting on the potential mechanism, the researchers note that other studies have reported that the Bilberry extract may counteract the increased permeability of blood capillaries. Moreover, the pine bark extract may improve the lining of blood vessels and lower overall blood pressure, said the researchers.
“The results obtained from this, and the previous pilot trial on intra-ocular pressure, appear to be very promising,” wrote the researchers. “A much larger study with a significant number of patients should further assess the benefits of the supplement for controlling intraocular pressure,” they concluded.
