Supplement infographic: most users are healthy to begin with

I love this new graphic from the Council for Responsible Nutrition, the trade association for the dietary supplement industry.

My favorite: “Supplement consumers are more likely to engage in other healthy habits than non-consumers.”

This is delightfully ambiguous.  Does it mean: Supplements make consumers healthier?

Or does it mean: consumers who are healthy to begin with are the ones who take supplements?

I vote for the latter.  That’s why the great majority of studies of supplements and health show no effect.  Study subjects are already healthy and don’t need them.
