What are anthocyanins?

Anthocyanins are naturally occurring compounds found in many fruits and vegetables, notably in berries such as blueberries. They belong to a class of molecules known as flavonoids and are responsible for the vivid red, purple, and blue colors of many plants. There is evidence suggesting that anthocyanins may offer cognitive benefits, such as mildly enhanced memory and reduced oxidation of LDL (bad cholesterol). They may also play a role in reducing insulin levels and potentially offsetting cognitive decline related to conditions like Alzheimer's disease. Studies indicate that consuming blueberries, which are rich in anthocyanins, can be beneficial for brain function. Depending on whether the anthocyanins are obtained from supplements or fresh blueberries, different dosages are recommended to experience cognitive benefits 1.
