It seems neither the article nor study seem to focus on particular ingredients, though with the information they had access to, maybe this was not possible. Two different supplements in any category, like weight loss, can have wildly different ingredients and thus completely separate safety profiles.
I know how a supplement containing Yohimbine made me feel one time and I'm curious if extremely strong stimulants like this are part of the danger. I would have preferred to see if there were commonalities between the ones that caused more adverse events, such as: inaccurate dosages, contamination, certain ingredients, etc.
It just seems like the conclusion is, yes, some supplements can be dangerous for various reasons. Does that really tell us anything we didn't already know?
