AKA "Proprietary Blends", usually with some cuckoo pseudo-scientific name. There are a handful of proprietary blends that actually list the quantity of each ingredient.
Exactly, I was going to mention the proprietary blends too. The reason given for using them is that other companies can't steal your fantastic formula but it's just an excuse for pixie dusting the expensive ingredients. Though I think they still have to list the ingredients 'in order of appearance' so to speak, highest first so you can get somewhat of a clue. Most outrageous example of a 'patented extract' I saw is an astragalus extract with supposed life extension benefits. It's an inexpensive herb but this one brand sells a few mg for like a thousand bucks a bottle without even telling you what it's standardized for.
