14 year old use XFB Xtreme Fat Burner and is it effective?

[jt]

I'm a 14 year old and I'm 6'0 tall. I'm pretty tall for a grade 9 in school but I'm also over weight quite a bit. After looking around websites I found this product by xyience called the XFB Xtreme Fat Burner and all the reviews of the products are very positive and so i want to try this product out but I don't know if supplements are bad for 14 years old. And I wonder if products like these actually help me burn fat faster when i exercise while using them cause a lot of these stuff are ineffective.
