Blueberry extract is a supplement derived from the berries of the blueberry plant. It is commonly used in protein powders as a natural source of antioxidants, specifically flavonoids and anthocyanins, which give the berries their dark blue color.
Blueberry extract has been shown to have numerous health benefits, including improving cognitive function, reducing inflammation, and potentially lowering the risk of heart disease. It may also have benefits for insulin sensitivity, which can be important for managing blood sugar levels and preventing diabetes.
In terms of safety, blueberry extract is generally considered safe for most people when taken in recommended doses.
