Hi Shariv,
There's not a lot that's going to interfere with each other supplement wise, as long as you're talking about basic vitamins and minerals. When you get into herbs, there sometimes are incompatabilities, but not a lot. A lot of vitamin C and some of the anti-oxidants can make artemisinen less effective, but that's pretty much a whole regimen in itself.
The biggest thing about taking a lot of supplements is to 1) take them with food, as many of them can be really hard on the stomach, 2) make sure you are drinking plenty of fresh pure water to both provide transport and absorption of the supplements into the cells and to make sure to also provide adequate detoxification , and 3) space the supplements out, so that you aren't dumping a whole goo gob of stuff in the stomach at once (mixing acidic and alkaline could be a problem if the one neutralizes the other. e.g. don't take baking soda and an apple cider vinegar supplement together)
If you will send me a private reply with a list of what you are taking, I'll look at it and let you know if I see any major conflicts.
Sincerely,
Tre
