Hi, Im 16 turning 17 in 2 months and overweight. Do you think that its ok to take weight loss pills.?

I cant go to a doctor because my mom will have a cow if she found out. But the weight loss pills that im interested in taking are Essential Boost with powerful green tea extracts. It has EGCG and is a dietary supplement. Im 5 foot 1 and 135 pounds and its not really muscle so any advice and information will help. Thanks so much =) o yea and im not pregnant or have any disease such as diabetes or high blood pressure.
