Caffeine

After as little as 10 minutes, the caffeine concentration in your blood reaches half the maximum concentration, which is enough to have an effect. The caffeine reaches maximum levels, making you most alert after 45 minutes. Depending on how fast or slow your body is able to break down the drug, you could feel the effects of caffeine for 3 to 5 hours.

Coffee contains hundreds of different compounds. These include many antioxidants that protect our bodies from damaging chemicals called free radicals. These molecules cause aging and are associated with illnesses such as cancer and heart disease. NIH studies show that coffee drinkers have a reduced risk of Alzheimer's, Parkinson's, type 2 diabetes and many other diseases.
