Ed–– I don't generally put much stock in promotional blah blah, but the website of EMB Medical, Inc., the manufacturer, says EB-N5 [is] " … classified as [a] medical [food], a unique category regulated by the FDA. Medical foods address the metabolic deficiencies associated with diseases to help manage chronic conditions, including blood vessel and nerve damage such as peripheral neuropathy." If it weren't for the fact that it was my neurologist who suggested I give it a try, I'd probably have taken a raincheck. If my EB-N5 arrives on Monday as scheduled, I'll start taking it that evening. And definitely I'll keep you posted as I go along. ––Ray
