I bought this because I heard that anthocyanins are effective for gout. This is my personal experience so I don't know if it applies to everyone else. I feel a lot of improvement in the pain in my heel and big toe area. I didn't feel the effect right away after taking it, but it seems to have gotten better than before I started taking it regularly for a long time. On the other hand, it is said to have antioxidant, anti-inflammatory and cholesterol-lowering effects, so I plan to consume it regularly.
