I just wanted to thank you for posting this info about 3lac. Since reading your initial post I have since googled each ingredient of 3lac and haven't found good things. I have been giving this stuff to my 3.5 yr old autistic child for 4 mths with great results. But, great results or not, since learning the truth I am running from this product! There is also something on the box about 'spore forming' and what I read about that on the web that is an untrue statement. Not good at all. I don't know why he'd have great results with stool issues with this product but if he did better on arsenic, it would still be arsenic. Thank you for posting this. I happened upon this forum while searching google for SF722 info THE VERY NIGHT YOU FIRST POSTED about this. So, it had to GOD HIMSELF that lead me to learning what risky thing I was giving my boy. Thank you thank you thank you!
