My son works out using the powerlift system. He is very concerned with nutrition and diet. Some nutrients that are good for you may be able to be refined from foods into a concentrate. This is how workout supplements are made. One supplement that many bodybuilders like is L-Arginine. Some of the comments I have seen about it are (paraphrasing):
- caps are easier for swallowing
- caps can be opened to mix in drinks
- it works
- a definite improvement in performance
- the pills are HUGE and very difficult to swallow
