Bilberry extract for better eyesight
Bilberry (Vaccinium myrtillus), alsoknown as the Whortleberry and Blaeberry, is a small shrub found onheaths where it grows to about 60 centimeters tall. You will findmany eye formulas that contain bilberry, including EyesightRx. Bilberry herb has more than a dozenanthocyanosides for eye health.
Bilberrydosage
It is not clear at this time whatthe ideal bilberry dosage would be. For the time being, a dosage of10 to 100 mg of a 100:1 bilberry extract comprised of 25%anthocyanosides should suffice.
Bilberry Extract, 80 mg, 60Capsules
BilberryExtract, also referred to as blueberry, is a potent extractyielding key bioflavonoids and antioxidants called anthocyanosides,anthocyanins, ellagitannins, and proanthocyanidins. A controlledextraction process guarantees at least 25%anthocyanosides.

Bilberry andanthocyanidins
Anthocyanosides are the pharmacologicallyactive constituents of bilberries. They consist of a backbone knownas anthocyanidin which is bound to one of three sugars: arabinose,glucose, or galactose. Five different anthocyanidins in bilberryproduce more than fifteen different anthocyanosides. The freshbilberry fruit contains an anthocyanoside concentration of 0.1 to0.25 percent. A concentrated bilberry extract however yields 25%anthocyanidin content, which corresponds to about 38%anthocyanosides.
Bilberrybenefit
The benefit of bilberry rests mostly on its ability to providesubstances that are beneficial for eye health. Bilberry may benefitthose who have macular degeneration or are predisposed to acataract. Phenolic compounds in bilberry are of benefit asantioxidants.
Bilberry extractavailability
Bilberry extract is available in a number of concentrations andextract potencies. These include 5 percent anthocyanosides, 10percent anthocyanosides, 20 percent anthocyanosides, and 25 percentanthocyanosides.
Bilberry is a good source ofquercetin
Consumption of black currants, lingonberries and bilberries, vaccinium myrtillus, increases serum quercetinconcentrations.

Biomarker Laboratory, National Public Health Institute, Helsinki,Finland.
Twenty subjects consumed 100 g/day of berries - black currants,lingonberry and bilberry - for 8 weeks. Twenty subjects consumingtheir habitual diets served as controls. The serum quercetinconcentrations were significantly higher in the subjects consumingberries compared to the control group. During the berry consumptionperiod the mean serum concentrations of quercetin ranged between21.4 and 25.3 micro g/l in the berry group, which was 32-51% highercompared with the control group. According to 3 day food records,there was no difference in quercetin intake at baseline, but at 8weeks the intake was 12.3 /-1.4 mg/day in the berry group and 5.8/-0.6 mg/day in the control group. The results indicate that theberries used in this study are a good source of bioavailablequercetin.
Bilberry Herb studies
Dietarysupplementation with bilberry extract prevents macular degenerationand cataracts in senesce-accelerated OXYS rats.
Cataracts and macular degeneration remain the major causeof blindness and acuity of vision deterioration in the elderly.Both pathology have been attributed to damage by free radicals,there has been a great deal of interest in antioxidants.Bilberry''s flavonoids are known as potent antioxidants, scavengingfree radicals and used for multiple age-related ocular disorders.There are no experimental studies, devoted to estimation ofbilberry effect. To explore this one the senescence-acceleratedOXYS rats with early senile cataract and macular degeneration wereused. From 1.5 to 3 month OXYS rats were given control diets orthose supplemented with 25% bilberry extract (BE, 20 mg on kg ofbody weight including 4.5 mg of antocianidin) or vitamin E (40mg/kg) for comparison. The testing at 3 month showed that more then70% of control OXYS rats had cataract and macular degenerationwhile the supplementation of bilberry extract completely preventedimpairments in the lenses and retina. The VE had no significanteffects but both antioxidants decreased lipid peroxides in theretina and serum of OXYS rats. The results suggest that long-termsupplementation with bilberry extract is effective in prevention ofmacular degeneration and cataract.
Inhibition of protein and lipidoxidation in liposomes by berry phenolics.
The antioxidant activity of berry phenolics such asanthocyanins, ellagitannins, and proanthocyanidins from raspberry(Rubus idaeus), bilberry (Vaccinium myrtillus), lingonberry(Vaccinium vitis-idaea), and black currant (Ribes nigrum) wasinvestigated. The antioxidant protection toward lipid oxidation wasbest provided by lingonberry and bilberry phenolics followed byblack currant and raspberry phenolics. Bilberry and raspberryphenolics exhibited the best overall antioxidant activity towardprotein oxidation. Proanthocyanidins, especially the dimeric andtrimeric forms, in lingonberries were among the most activephenolic constituents toward both lipid and protein oxidation. Inbilberries and black currants, anthocyanins contributed the most tothe antioxidant effect by inhibiting the formation of both hexanaland protein carbonyls. In raspberries, ellagitannins wereresponsible for the antioxidant activity. While the antioxidanteffect of berry proanthocyanidins and anthocyanins wasdose-dependent, ellagitannins appeared to be equally active at allconcentrations. In conclusion, berries are rich in monomeric andpolymeric phenolic compounds providing protection toward both lipidand protein oxidation.
Historicalnote
Some of you history buffs may recallthat during World War II, British Royal Air Force (RAF) pilotsmentioned that their night vision was clearer whenever they atebilberry preserves before starting out on their evening bombingraids.
