Does Proactol have Halal Certificate?

I don't know about it being halal per say, but it is indeed kosher and organic.

I do not know. I read in squidoo lens about proactol huge discount and a secret discount coupon code is revealed there.
It says a proactol box costing $99.95 can be bought at just $34 by using that discount coupon.
See source box for details

If there isn't anything mentioned about it in Quran/hadith (which i guess most probably not) then its okay
unless..its bad for your health.
Otherwise, OK
