Energy Drinks Unmasked

A friend of mine, Jeff wondered what is in energy drinks that makes them work and are they safe. That sent me scouring my personal stash and the web for answers. The following excludes the larger volume drinks, such as Monster, Red Bull, etc., and offerings from Pepsi, Coke, and others. Those all have their own host of reasons to avoid, but that is for another discussion.

Most of the two ounce shot energy drinks contain varying amounts of taurine, caffeine, sucralose (splenda), niacin, vitamin B12, B6, folic acid, sodium, acai fruit extract, guarana, and many other ingredients that are almost impossible to spell or pronounce. Others have green tea, L-carnitine, ginseng, yohimbine, and all contain water and natural and artificial ingredients (whatever that means). Most have zero calories listed. Many have warning not to take more than one every four or six hours (likely in self defense from the FDA).

Many are described as an energy shot to enhance concentration and improve performance. They do not specify what performance. A number of them are designed specifically for hangover relief, and a few diet suppression. The only difference I could find in these ingredients was more vitamin B12 (in one type 10,000% of the daily value). Some of the names are 'pure energy, 5-hour energy', 'eternal energy, 'extra energy', 'Extra strength energy', 'java-mite', 'XX Energy', 'high energy', 'hangover recovery, 'diet aid', etc.

The majority of the dozen I checked come in little white two ounce bottles covered with shrink wrap covers. Interesting that so many have the identical bottle (with the exception of the bottom indents) and wrapper type regardless of manufacturer. Could find no common denominator other than that. Prices ranged from as low as $.88 to $3.98 for the same size. Interesting to note that one of the most popular and most expensive, 5 hour energy has the least liquid at 1.93 ounces.

Most sites agreed the biggest reason for the jolt is the large amount of caffeine, about as much as two cups of coffee in a small two ounce dose. Studies show they are no better as a pickup than coffee, although they are concentrated in less liquid as well as more convenient and quicker to drink. Annual revenues for energy drinks is about 13 billion dollars.

Bottom line, the caffeine is the kicker, the vitamins go out in the urine, the other ingredients are for flavor, preservatives, and color. None have proven to be bad for us, probably due to the trace amounts contained. None are good for children for the same reasons as coffee. In spite of a few rantings by the usual fear mongers, these have yet to be proven unsafe, with the exception of occasional jitters common to those who do not well tolerate caffeine. In my case, they seem to work as advertised and do not provide any physically noticeable high or low.
