A couple years ago I went on a reading binge on multis, herbs, all this stuff, and I can't find the links I collected.
But, I have a secondhand story, perhaps I got it from this site (I don't remember), about a plumber that dug literally handfuls of undigested tablets from people's septic tanks. The person telling the story recommended staying away from multis that don't dissolve well.
So I took my multi and put it in a cup of water overnight to see how well it dissolved. It did okay. Not very scientific, but good enough for me. I'm told the experiment works better with some vinegar (like your stomach acid). Believe me, you can actually obsess about whether you're getting all the nutrients you need. Bioavailability, synergy, blah blah. I'd say the sanest choice is to eat healthy, and get a cheap multi that dissolves well. And then of course take it diligently with your breakfast.
With some vitamins, like C, it's better to get a time release pill and down that separately from the multi. It's a very important vitamin, and the time release makes sure you get a good even flow throughout the day.
Don't bother with all the fancy herbs and stuff, if you think you really need one of em, get a separate pill that has a proven amount of active ingredient. I'd say like $25 bux for a 100 pills is average for a decent multi. I paid $32.99 for a 120 tab jar of Fox Nutrition's "The One and Only" which is "sustained release and chelated." Fox is a local joint here in SoCal.
Inorganic iron (ferrous sulfate) attacks vitamin E. Organic iron (ferrous, ferrous fumarate) does not. Chelated just refers to minerals that are molecularly composed to absorb better. Calcium supps should not be taken with iron. The iron doesn't absorb. The little bit of calcium in a multi is fine, but if you're taking extra calcium,
wait till dinner.
