No. some ingredients sway blue, others are not safe prepregnancy.
What that is there, is a very strong laxative. My personal opinion (take for whatever it's worth) is that is a scam. Makes a person have to go #2 like nobody's business so it seems like you're getting rid of toxins when really you're just pooping a lot ;)
psyllium, senna, cascara, aloe, slippery elm, inulin are all very powerful laxatives. 90% of the other stuff makes it taste good or is a preservative.
