Re: Is there a limit?

Audrey-Just reading through past posts. Once again you have provided great info. esp about the various vitamins, minerals, problems with taking iron and zinc together( I didn't know this) etc. Where do you get this information? Is it a multitude of sources and alot of internet searching on everything you take or is there some central resource that you rely on ? It is all so confusing to me. I think that I am constantly cancelling out what I supplemented by what I ate before or by the several supplements I take together.And, I need to take calcium so there is another problem because calcium taken near for example iron or thyroid med will diminish both. It is difficult.
