Energy Boosters: Can Supplements and Vitamins Help?
This is the subject of a nice little article over at WebMD.
Now, I like a good pre-workout booster – which is usually some combo of caffeine with nootropics (heck, even a stiff shot of coffee and a couple tyrosine caps will do in a pinch). I think they really do help with focus, and the ability to dig just a little bit deeper to get that last rep or two out. The bottom line, however, is that the best general energy booster I know of, is activity. I sit at my computer for long hours each day – and there are times when I find my forehead sinking towards the keyboard. When that happens, a brisk walk, or a few short minutes of more intense exercise (i.e., wall squats, pushups, rope jumping), perk me right back up again.
