Fish oil is good and seems to have many health benefits beyond the performance enhancing ones.
The reason I left off ZMA is because I've heard from several sources that it actually provides no added benefit over just supplementing those minerals independently or via multi-vitamin. From what I was told, the benefit of ZMA is not a result of some magic binding of the minerals but rather due to the fact that most individuals are deficient in them in the first place. As far as I know, there is only one supporting research study on ZMA and it was funded by the company that sells it. This raises a big red flag for me due to the conflict of interest. Also, the fact that many of the pro athletes who were sponsored by ZMA have since turned out to be BALCO drug cheats takes away some of the luster from their anecdotal reports about its effectiveness. So while I'm certain ZMA supplementation would be beneficial I'm still undecided as to whether it would be more so than supplementing those minerals independently or via multi-vitamin. Carl, have you ever seen anything besides the Conte study?
