This is really a SUPER FRUIT, the concentration of vitamin c, it is almost unbelievable, like 40-60 times more than in oranges. Is hard to imagine, and imho it is not the same to eat the synthetic artificial vitamin c, than the one from a natural source.
It is sour? Yes, but you can put a sweetener, or do juice and mix, the flavor is good (not like Noni LOL). I love this fruit since I found it growing, (literally) inside the water in the middle of the Amazon like 10-12 years ago.
