Can a 13 year old struggling to lose weight take the pill Acai Optimum Dietary Supplement?

I'm 13, And I take these pills. My mom bought them for her, and she is a nurse. I asked if i could take them for my weight ( I'm a 185lb male, 5"6, I know, holy crap) and she said since they are just a concentrated Acai berry pulp, It's just like eating a hole bunch of Acai berry's. They really boost your immune system and metabolism. Just read and see what's in them, if its a hole list, don't take them, if it's short and you understand what each item is, I don't see anything wrong with it.
