The Shaklee Difference has never been more profoundly expressed than by the way they create their soy isolate protein drinks.  First and foremost, Shaklee does not use genetically modified (GM) soybeans.  This is very fortunate, because recent animal studies indicate numerous health risks associated with GM food consumption, including infertility, immune disruption, accelerated aging, and bizarre changes in organs like the liver, kidney, spleen and gastrointestinal tracts of tested animals.  The American Academy of Environmental Medicine's scathing review of the health threats posed by GM consumption is most revealing.45  Shaklee adopted an expensive genetic certification process called the Identity Preserved Program to guarantee that the soybeans they use are not genetically modified.
