Caffeine and Fatigue

Caffeine works mainly through two separate but interrelated pathways. When you consume caffeine, the caffeine actually goes through the blood-brain barrier and interferes with adenosine. There's another pathway by which caffeine also works, which is through another cellular messenger called psycho-gampia. It will bypass a lot of the chemistry here in biochemistry,. You get benefits such as mood muscle relaxation. You get some buzz feeling, some energy. Of course, you get thermogenesis. These are all effects of caffeine through the second-anime process.
