What's a good resource to determine vitamin and mineral conflicts?

I read the other day that Vitamin D3 and Magnesium compete for absorption, so I stopped taking them at the same meal (Now I take the D3 with breakfast and the Magnesium with dinner).

Are there other conflicts we should watch out for? Are there good resources that enumerate these types of things?

Well, until very recently, the most of it was available via Google Books. Recently they removed most of it.... its amazing book, really. I have put google alert on this book + torrent :P

I would be willing to bet this is the best answer that is going to get thrown out. I hate that it's an $80 book though...

Ultimate, IMO:

Herb, Nutrient, and Drug Interactions: Clinical Implications and Therapeutic Strategies

Its very technical, tho. See preview on Google Books and there is free Vitamin D chapter.

I think it's safe to assume that any mineral is going to compete with any other one for absorption, especially at supplement doses. If you are targeting one, it may be at the expense of several others. If possible, segregate mineral supplements from each other and from the meat/organs you eat. Some vitamins enhance mineral absorption like B6+Mg and ascorbate+Fe. Enhancing the Fe, for example, would be to the detriment of other minerals like Zn in the meal. I've never seen any evidence of the fat soluble vitamins competing with minerals for absorption, though I suppose it's possible. Vitamin C is a glucose derivative, so they are close enough in structure that they utilize the same transporters and thus compete.

You're likely only going to have issues with conflicts and imbalances when supplementing with single vitamin/minerals only, or when eating a single food non-stop. Just eat a varied diet and you avoid the whole supplementation/conflict/imbalance thing all together.

You might like this.

tl;dr: it's only an issue at higher levels.
