If dietary supplements were regulated, they would probably 1) cost 10x as much 2) be prescription-only 3) only be affordable through health insurance 4) there would be 1/10th the innovation compared to what we see now.
I'm a consumer who consumes a basic set of supplements (vitamin d, vitamin k2, magnesium, multivitamin) and I'm very happy with how things are now.
I'm glad that the extreme level of waste, red tape, and corruption that affects the rest of the medical industry does not affect dietary supplements.
