DEBRA'S ANSWER:

I've listed some at Debra's List: Food: Supplements. There are more too.

We've also discussed vitamins several times on this blog. There's a summary of links to the posts along with some general comments from me at Q&A: Vitamins.

I don't know what you consider a "reasonable" price, but the vitamins you describe are going to be more expensive. I didn't read the article you cited, but I doubt if any of the "whole food" supplements I've been recommending for years contain titanium dioxide, or anything else. They don't need any fillers--they are 100% food.

Generally the vitamins that contain fillers need fillers to hold them together because they are synthetic vitamins and have little material of their own.

That's why I've been recommending whole food vitamins for more than twenty years.
