Yes, there are supplements that you should not take together for various reasons. And there are some that you want to combine for various reasons.
For example: Vitamin C helps with Iron absorption. Vitamin D helps with Calcium absorption. You don't want to take Iron and Calcium together as they hinder each other's absorption.
Vitamins A, D, E, and K are fat soluble - you can OD on these, so stick to the recommended doses. The others (B complex and C) are water soluble and excess will be excreted in your urine.
I've found that a well balanced multi-vitamin is good. I don't believe that my injured guts absorb things like they should. I've had a heck of a time finding the right vitamin for me, but through some research found Forvia. Forvia is made for IBDers. I don't have any of the cramping or nausea with it like I did with others.
I also like a probiotic. In fact, I'd almost swear by them! I started small with a chewable and then moved up slowly to where I'm at now with 4.4 billion CFUs. When I started taking them, I noticed a difference within a day! Yah for good bugs :)
One resource I use is a book called "prescript
ion for natural healing". It's a good reference for what specific supplements are good for. However, some of what it says is totally kooky!!! I'd check your local library if you're interested in it. Maybe they even have a website, I haven't looked in ages.
Whatever you decide to do - run it by a medical professional. Make sure they know everything you are taking - OTC and prescribed!
Best of luck!
