Can you explain if it's safe for a 13 year old to take raspberry keytones?

Of course: It's a placebo and does nothing. It won't help you lose weight or do anything else for your benefit. Eat sensibly, avoid sugary and fatty stuff, get with a fitness group, and you'll accomplish your weight loss / fitness goals without having to waste money like this. And get some real respberries -- and remember how good real, nourishing food tastes.

Who cares?: Rasberry ketones are worthless -- not a therapy for weight loss or any other medical problem. Don't get your medical information from friends, tv or internet scams. Dr. Oz is rarely correct about anything he says, even when lying to a congressional committee.
