Cheryl - no use of asking doctor LOL - I can bet you a 100 $ that he never even heard about Carrageenan ! If you want to know about it go on the net and do your own reserch.
Lecia - it is very possible that soy could effected your period - heavy periods are sign of estrogen dominance !!! So, if you already had high estrogen /progesterone ratio , than adding extra estrogen definitely can effect your balance
The problem is that soy is now added to EVERYTHING - look at the labels of prepack food . So, we are eating it ANYWAY knowing it or not and adding extra on the top of it all can really effect our body !!!
