If I were to try to give a complete answer, I&#x27;d probably spend fifteen minutes googling &quot;Ensure vs Soylent&quot; - there are some good matches there through discussion boards that analyze the ingredient breakdowns, also some replies from the soylent people too.  Ensure is definitely more expensive in those analyses, and that&#x27;s from before soylent&#x27;s recent price drop.  Beyond that, it appears to be a rather different ingredient list - looks like Ensure doesn&#x27;t have much in the way of fiber, has more sugar, etc.
