Anthocyanins are the pigments that give blueberries, blackcurrants and red cabbage their deep purple and red colors, and they act as antioxidants in the body. People mostly look at them for thinking and memory, but a small trial of 14 people found no effect on verbal memory or working memory. The evidence is very limited, since so few people took part, so these results say little about how they might work for others.
