>>8654842Yeah I take ZMA, but like basically all vitamin supplements (a case can be made that D3 is an exception) it's overrated and you ought to be focusing on dietary sources which tend to be absorbed better. The infamous "ZMA study" that found significant testosterone and sports performance benefits has to weighed against others that failed to replicate its results, personally I think that some of the ZMA study group (handegg players) were on steroids which is known to deplete zinc, so they got a disproportionate benefit from supplementing it.
>>8654844Multivitamins don't work well at all since the doses aren't optimised and some of them inhibit uptake of the others, e.g. vitamin C opposes iron. Also there's no need to supplement most of them if you're eating a healthy diet. D3, zinc, magnesium and high quality fish or krill oil is all I would suggest bothering with. Iodine and selenium have their enthusiastic shills, but unless you live somewhere with heavily fluoridated water you can just eat fish and radishes.
