Erin, I have gotten my vitamins from www.iherb.com since 1999. They are so much less than the stores. I could not afford all of what I take if I got them in stores.

Since you're on Pred, you do need to take more supplements. It's a good thing. I think a few, appropriate supplements is a great idea. It's between you and your doc to decide what works for you.

I hope the IVIG goes well.

Annie
