Also some add fillers that aren't good either.
gmfuzzy sorry to hear about your husband. I hope he's doing well.
There is a huge difference in thinking about substitutions in life-saving pharmaceuticals versus in supplements. I think as long as you're paying attention to the actual form and amount of the active ingredients in supplements you're fine. e.g. substitute 50 mg magnesium citrate for 50 mg magnesium citrate.
The difficulty arises when you substitute, for example, 50 mg citrate for 50 mg magnesium HVP chelate or 50 mg magnesium oxide. These different forms are absorbed in different proportions so the 50 mg isn't the same. HVP chelate is far more absorbable than citrate which is more absorbably than the oxide. HVP = hydrolized vegetable protein is also more expensive than other forms, and noticeably isn't used in the Natura products.
As with prescription and over-the-counter pharmaceuticals, if we're sensitive to non-active ingredients, then of course we have to pay attention to those as well.
