Increased alertness and feeling awake, predominantly because of how caffeine blocks adenosine in the brain and because it increases blood flow through widened blood vessels A boost in memory and concentration, mainly because it increases the production of dopamine Pain reduction, especially headaches,…

What are the anti inflammatory effects of caffeine?

The anti-inflammatory effects of caffeine are due the nonselective competitive inhibition of phosphodiesterases (PDEs). Inhibition of PDEs raises the intracellular concentration of cyclic AMP ( cAMP ), activates protein kinase A, and inhibits leukotriene synthesis, which leads to reduced inflammation and innate immunity.
