WBF - why wouldn't you trust it from Amazon?
They just get their products from the source.
A lot of the preferred brands only sell to licensed medical professionals. I went to Nutramedix's website and see they do sell directly to consumers. Still when you buy on Amazon you usually are buying from third party vendors not directly from the manufacturer. On Amazon it lists the supplier as Johnson Distributors. I didn't see that name on the product label, so it could be a third party.
I know Thorne will only sell to licensed medical professionals, but I once ordered their NAC off Amazon because my doctor was out of it. There was something different about
it, but I used it anyway out of desperation. There are unscrupulous people out there who will sell altered, expired, or bogus stuff packaged in bottles from legitimate products.
I would call Nutramedix and ask them about
it before using it.
