The hairs on my neck stand up for MLMs as much as anyone but just because something is marketed in a smarmy way doesn't always mean the products are crap.
Who remembers Amway? I still use the LOC - even though it's been somewhat reformulated through the years.. used to stand for liquid organic cleaner, now they call it legacy of clean *eye roll*
My mom swore by the SA8 laundry soap - but I seem to recall heated phone calls way back when with her saying she had no intention of going to a meeting.. selling product or *gasp* hosting parties.. just sell me the soap damnit.
Utopia silver has a trace mineral product also.. both liquid and caps. My wallet cries every time I consider it though.
