One of the tell tale signs for identifying someone as a hardcore fitness freak is by the amount of supplements they take on a daily basis. However, while this may be worn as a badge of honor by many (proof of their unrelenting dedication to “aesthetics” or some other such goal), the majority of these supplements have very little scientific proof to back up the various claims of their efficacy. In other words, the main thing these gym junkies are paying for is a placebo effect.
