Bilberry is rich in anthocyanins. Bilberry anthocyanins are advanced pharmaceutical intermediates that help maintain the integrity of capillaries and stabilize collagen. Anthocyanins are also powerful antioxidants.

Ripe bilberry fruits are rich in brassic pigments and anthocyanins used as antioxidants. Healthy people or visually impaired patients can use bilberry extract alone or take β-carotene and vitamin E at the same time, which can significantly improve night vision, respond quickly to darkness, and restore visual acuity faster after the eyes are exposed to bright light.

Anthocyanins can stabilize the phospholipids in endothelial cells, maintain the structural integrity of the arterial wall by increasing collagen and mucopolysaccharides, thereby protecting veins and arteries through synthetic compounds. Anthocyanins also prevent the aggregation and adhesion of platelets on the surface of endothelial cells.

The benefits of bilberry extract are mainly reflected in the following aspects:

Normalization of capillary permeability

Anthocyanins have strong "vitamin P" activity, which can increase the level of vitamin C in cells and reduce capillary permeability and fragility. This function can contribute to the decreased permeability of the blood-brain barrier (increased blood-brain permeability is considered to be related to autoimmune diseases of the central nervous system, schizophrenia, "brain hypersensitivity" and a variety of other mental diseases).

The enzymatic and non-enzymatic degradation of brain capillary basement membrane collagen helps maintain the brain's resistance to drugs and naturally occurring degradation products.

Vascular disease

In view of its normalizing effect on capillary permeability, bilberry anthocyanins are used to treat fragile capillaries, purpura, various cerebral circulatory disorders (similar to the corresponding effects of Ginkgo biloba), insufficient venous function, varicose veins and other causes. The fragile renal capillaries cause the loss of trace blood in the urine (capillary leakage).

Eye diseases

Bilberry extract has shown a clear helping effect on the eyes, presumably by improving the ability of oxygen and blood to transmit to the eyes. Many eye diseases, including cataract formation and macular degeneration, are ultimately attributed to the damage of free radicals to the eyes. Bilberry extract acts as a powerful antioxidant that protects the eyes from free radical damage.

Improve vision

Healthy people use bilberry extract to improve night vision acuity, increase the speed of black vision adjustment and increase the speed of vision recovery after flashing.

Effect on platelets

Excessive platelet aggregation is related to arteriosclerosis and thrombosis. Anthocyanins, like other flavonoids, show significant anti-polymerization effects on platelets.
