Wild bilberry (Vaccinium myrtillus) delivers a high concentration of anthocyanins, the water soluble pigments that give it that deep blue tone. It offers more anthocyanins and a stronger antioxidant punch than cultivated bilberry or blueberry.
People reach for wild bilberry mainly to ease eye fatigue, sharpen night vision, and support steady circulation. The anthocyanins are water soluble. They absorb straight into the bloodstream without needing dietary fat.
You typically take it as a capsule or extract. Doses change from product to product. Some people notice mild stomach upset. Its safety during pregnancy and breastfeeding is unknown. Bilberry may interact with blood thinning medications like warfarin or aspirin.
