Multivitamin powder?
I'm not very familiar with those....I hope someone else can chime in and help you out on that one.
I like to stick with vitamin packs myself, if not the bottles of vitamins.
What's CLA?

You can add this to your diet if you've already got it where you want it to be. This is just a staple to help you out. It won't work you wonders but it helps out a bit with fat loss.
I would personally plan on investing in a decent multi that's NOT powder so you can have something else to start up on once you're done with your Multi-Powder.
