When it comes to boosting dopamine levels, blueberries rule. Blueberries give the body a greater ability to release dopamine, an energizing, stimulatory neurotransmitter. They also protect us from the loss of dopamine cells normally seen with aging. By increasing brain energy production and maintaining youthful brain function, dopamine exerts an extremely important antiaging effect. Since dopamine levels decrease with age, blueberries become even more important as we get older.
