Need suggestion for the best pre-workout supplements?

I am much disturbed regarding my over weight. I do lot of workout and follow strict diet plan, but still I am not getting much accurate results. I get faint many times while doing workout or during my office time. Please suggest me something which supplement should I take before my workout sessions, sSo that, I can be more active during my work time.

Besides nutritional supplements, you can also try out for some RiteBite Max Protein - Choco Slim bar just for a change.
