i am reading alot of think about supplementation and everything we should take everyday. I dont know if its a big industry or its really helpful. The only supplement tested on the market is CREATINE MONOHYDRATE and the etude and the long time test show that it really work it long term !
but what about multi-vitamine, zinc, magnesium, vitamine D and named it....
Is it really useful ? where can i get the proof that it really work.
