I was going to say this too, but it's not really true. You are responsible for doping substances in your body no matter how it gets there. So if you eat some contaminated food or supplements, that's considered doping. Now, like most, I believe that a lot of those claims are just cover, but that still leaves some that truly tested positive that way.
I don't really take any supplements, so that leaves me with a lower chance of taking contaminated supplements. But last year, I was taking some Vitamin D, because I live far north where I might not see the sun much all winter. But I didn't check the WADA website to check on the legality of Vitamin D (assume it's OK, but if you were really in the testing pool, you'd check EVERYTHING that you take). Plus what you buy might not be what's stated on the bottle due to either scams or contamination.
Who cares...I take a ton of supplements. They're are safer and not toxic like pharmaceuticals. And there's a lot of reputable supplement companies out there that don't have contaminated ingredients. It's the cheap crap stuff from overseas companies that no one ever heard of that you have to be careful of. And vitamin D-3 is the real deal for your immune system & bone health because of the deficiency problem plaguing Americans because everyone is afraid of the Sun these days.
