The only things different about this one probiotic are:
One of the ingredients, silica. Sand, right? That's not in any of the other formulae he gets
One of the bacteria strains... L. Bulgaricus.
How do you choose which bacteria strains are the best? And could either of those 2 ingredients be causing a reaction? My pediatrician blew it off.
I found this description of bulgariucs on the Dr. Atkins website... it sounds great!
Bulgaricus: This probiotic may stimulate the immune system more than acidophilus. In an encouraging study of one hundred cancer patients, the bulgaricus strain known as LB-51 showed very impressive results as an adjunct treatment for a range of cancers. It enabled the patients to live longer, stopped or slowed tumor growth, and halted the cancer's spread through the body."
