--is that the dosage info is for three pills, not one, meaning each pill actually has much smaller doses than you would think, and that it's pretty expensive, given that.

I would think you could put together a "cocktail" from other products--and probably not even too many others, so you wouldn't have to take a lot more pills--through Swanson or IHerb or Vitacost or one of the other on-line companies, that would be higher in quality and lower in cost.
