Blueberries for Antioxidant Support

Research suggests that blueberries and other polyphenol-rich berries may offer antioxidant and neuroprotective benefits, with one 2025 animal study finding that a berry-enriched diet helped prevent motor deficits, preserved dopamine-producing neurons, and reduced neuroinflammation in a mouse model of Parkinson's disease. The study also noted measurable differences in phenolic compound profiles in the blood and brain tissue of berry-fed animals, suggesting that dietary polyphenols from berries are absorbed and may exert biological effects. The available evidence on this specific topic is currently limited to preclinical animal research, which means findings cannot be directly applied to humans without further investigation. Studies in human populations, including randomized controlled trials, would be needed to draw firmer conclusions about the antioxidant and neuroprotective effects of blueberry consumption in people.
