I just started taking vitamins. I bought the Centrum Performance brand and so far I feel alot more energetic. But I was wondering if I should just start buying the regular ones since i drink a low carb Monster in the morning which has all those B vitamins that are in the Performance Pills. This way, I'll get Lycopene and more calcium with the regular Centrum but still get my B vitamins and energy with the Lo-Carb Monster. Your Thoughts?
