The worlds most consumed drug, Caffeine has long been known as the most commonly used nootropic substance.
It’s used in practically every nootropic supplement we’ve tested to varying degrees, and is commonly stacked with numerous other nootropics like L-Theanine and GABA.
The most interesting thing to note about Caffeine is that it is widely marketed under different names and in different forms. If you see the ingredients yerba mate, methylxathine, Trimethylxanthine, or 1,3,7-trimethylxanthine, don’t be fooled.
They’re are just fancy names for caffeine.
