Caffeine Addiction

Caffeine addiction is a dependence that builds with regular use, as the body adapts and needs more for the same effect, then reacts to stopping with withdrawal. Little research on supplements for it has been reviewed here so far, though people most often look at L-theanine and magnesium. The L-theanine studies covered anxiety and stress generally rather than caffeine withdrawal, so how well it helps here remains unclear.
