How much lead & cadmium did the previous one have? (with source please)
It's easy enough for you to Google up the details. The "issue" wasn't with the content but with their labeling -- they only included the California Prop 65 warning on their website, not on the product packaging (which they claimed was sufficient since the website was the only legitimate source of the product).
It's almost like people entering highly regulated industries should have domain experience and not just make it all up as they go along.
Probably not. The powdered form (1.5) had protein from brown rice which has higher levels of lead and cadmium. 2.0 gets the protein from soy which has lower levels.
