I started using this in the 80s, from a health spa in California.  It isn't fancy at all, nothing that has curative powers.  However, it gives flavor and taste to things so that you curb your use of butter, and regular salt.  I dump it on popcorn, baked potatoes.  When I need to tighten it up a bit, I stir some of the powder into hot water for a broth throughout the day at work, which seems to keep away that afternoon candy bar craving.
