On the 12/6/11 episode of The Dr. OzShow, Miracle Energy Drinks: Do They Really Work?, Dr. Oz shared the caffeine content of popular beverages:

Caffeine content per serving:
  • Dark chocolate is the lowest in caffeine content with only 20 mg.
  • Soda is next with 30mg.
  • Tea comes in with 50mg.
  • Espresso rates lower than coffee at only 100mg.
  • Coffee beats espresso with 135mg.
  • The highest caffeine drink/food in this list is the energy shot which may contain as much as 300mg of caffeine per serving.

Caffeine content in energy drinks can vary widely by product from as little as 80mg to as much as 300mg per serving. Consider that there may be more than one serving per can. Herbs may be added to the drink to enhance the effects of caffeine or act themselves as a stimulant like caffeine.

Just because it's natural, does not always mean it's safe. Side-effects of high caffeine intake can be a jittery feeling, body tremors, raised heart rate, and increased blood pressure. Dr. Oz says if you experience high blood pressure then do not go near these energy drinks.

Too much caffeine and stimulants can cause so much talk and chatter in the brain that memories are not laid down in the brain.

Long-term caffeine use is associated with adrenal fatigue. The adrenal glands are responsible for regulating our response to stress and when depleted the body is no longer able to respond to stress in an appropriate manner. Feeling overwhelmed, continually tired, lower brain power are all potentialities of a depleted adrenal glands and can lead to lower productivity and reduced mood.

Check out WatchingDrOz from 12/13/11, where Dr. Oz discusses the importance, function and ways to support the adrenal glands.
