Are you taking supplements? Do you know what's in them? Tainted supplements are increasingly in the news. Research has found that many supplements don't contain what they claim to, don't contain it in the advertised amounts, and they may contain other, dangerous substances.
In most countries, supplements are not regulated stringently, meaning that manufacturers get away with a lot of things that pharmaceutical manufacturers can't.
Always exercise extreme caution when using supplements. ALWAYS make sure you have provided information on the supplements you are using to your doctor or treatment provider.
