Hi G-Force, I can say for sure regarding a few of them -
Calcium is best absorbed with Vitamin D coupled (should usually find them together when purchasing a bottle of 600mg-1000mg Ca2+vit D) Vit D is a fat soluble vitamin
You multi-vitamin will have other beneficicial vitamins that are fat soluble, and other minerals which would be better absorbed with your meal.
Vit C is water soluble
Can't say much for the Taurine and Potassium , but believe the taurine would be treated just as the caffeine would.
Caffine is ok, and so is the Acetly-L-Carnitine.
Fat Soluble vitamins are : A, D, E, K
Best to take your multi with your earliest pro-fat or pro-carb meal (if there are trace amounts of fat in that meal)
Calcium you sweat alot of it out from lifting, and it might be best to take with your last meal while you sleep - it's important that you feed your skeleton too
Vitamin C (2-3grams), I read from a post that it's great to take this 2 hours (i.e. with your pre-workout meal)
Why are you taking the potassium? The taurine, caffine, and carnitine look ok to take in the AM empty. Let's see what others say.
