As a continuation on my post about choosing more natural energy drinks or shots as energy supplements, it's important to know how much caffeine it contains and caffeine sources.

Most energy supplements, whether they are drinks, shots or pills, contain some amount of caffeine.  Caffeine stimulates the central nervous system, increasing our attention span and focus, but there can be too much of a good thing. 

Individuals sensitive to caffeine may opt for a product with low caffeine content.  A typical cup of coffee has about 100 mg of caffeine.  Select one with no more than 100 mg especially if you are sensitive.

Compare the caffeine content now of leading energy drinks and shots.

Also, caffeine can come from many different sources.  Some energy products do not reveal exactly how much caffeine there is on the label so read carefully!

Caffeine is found in the beans, leaves or fruit of over 60 plants such as guaranine, coffee, black, green and white tea and even cholocolate or cocoa.  If the label doesn't indicat total caffeine content, don't buy it.  You may end up feeling more wired than simply alert and focused.
