I'm looking for insight into everyone's experience with all of the various supplements available to endurance athletes (whether novice or pro). If you believe the ads, they all work wonders. But I've never tried any of them. The only thing I use are energy drinks pre-ride and during the ride (Enervit Energy Mix) and gel packs during the ride (Enervit), and they are great for energy and hydration.
I'm not talking about the usual drinks we all use on the bike, I'm talking about the legal, performance-enhancing supplements that supposedly help with overall performance, cramps, fatigue, energy loss, etc.
Some examples: Sportlegs, EP-NO, First Endurance Optygen, E-Caps products, Hammer products, etc.
Any good results? Any bad results?
