I find the speaker on the video kind of boring to listen to. But the whole point is that we cannot just pinpoint anyone when their intention is to just make their body look good. I think, they are just overreacting because there are some stuff that needs to be "regulated" or "approved" to say that they are really helpful in our body. But think about this: FDA approves certain drugs and then would change their mind when they are already out in the market and would get bad reps. Weird.
