Bilberry

Bilberry (Vaccinium myrtillus) is a small, dark-blue fruit closely related to the blueberry, with a long history of traditional use in European herbal medicine. Rich in anthocyanins — the pigments responsible for its deep color — bilberry has attracted scientific interest across several areas of health. Research suggests that its potent antioxidant properties may help support eye health, particularly in relation to visual fatigue and retinal function, though findings have been mixed and more rigorous trials are needed. Studies also indicate potential benefits for blood circulation, inflammatory response, and blood sugar regulation, with anthocyanin compounds appearing to influence vascular function and glucose metabolism. Most supplemental forms are standardized to anthocyanin content to ensure consistency. As with many herbal supplements, the evidence is promising but still evolving.
