Rating (out of 5): 3

Bilberry (Vaccinium myrtillus) has been used traditionally in Europe for vascular health, particularly for supporting veins and microcirculation. The berries are rich in anthocyanins, which are flavonoid compounds with antioxidant properties. Several clinical studies and reviews have explored bilberry extract’s effects on venous insufficiency and related symptoms, such as leg swelling, varicose veins, and capillary fragility. Some randomized controlled trials indicate that bilberry extract may reduce symptoms of chronic venous insufficiency (CVI), including edema and pain, likely by strengthening capillary walls and reducing inflammation. However, the quality and size of these studies vary, and systematic reviews often note the need for more rigorous research.

The European Medicines Agency (EMA) recognizes traditional use of bilberry for relief of minor venous circulatory disturbances, although it stops short of endorsing strong clinical claims. Overall, while bilberry’s use for vein support is grounded in both a historical tradition and some scientific studies, the totality of evidence is moderate. It is generally considered safe when used appropriately, but more large-scale, well-designed trials are needed to confirm its efficacy and to standardize dosing.
