What are vigor drinks?
The term "energy drinks" was coined by clubs in the beverage business and refers to beverages that consist of caffeine in compound with other ingredients, such as taurine, guarana, ginseng, and B vitamins. Taurine is not an "upper" and has no known stimulatory result on the body. It is unclear why taurine is added to vigor drinks though it may sacrifice the jittery result of high caffeine dosages or offset the dehydration effects of high levels of caffeine, typical in vigor drinks. Substances such as guarana and ginseng are herbal stimulants that are often added to improve the effects of caffeine. For example, 1g of guarana ≈ 40 mg caffeine and may substantially increase the total caffeine in an vigor drink. B vitamins may be added to make the drinks appear "healthy" or because of their role in converting food into vigor or in supporting or addition the rate of metabolism. Overall, these beverages claim to contribute their consumers with extra energy.

Is there evidence that these vigor drinks increase energy?
There is little evidence that consumption of vigor drinks can significantly improve corporal and mental performance, driving ability when tired, and decrease mental fatigue while long periods of concentration. However, the study nearby these claims is limited, and it is not clear if these improvements are due to the caffeine, the other herbal ingredients, or the compound of caffeine and the other ingredients.
How much caffeine is in these drinks?
A range of numbers are quoted in distinct sources as to the caffeine content of beloved beverages. Within a general range, a twelve-ounce can of carbonated soda, such as quarterly or diet Coca-Cola® or Pepsi® has 30-45mg of caffeine. Mountain Dew® comes in higher at 45-60mg. An eight-ounce serving of brewed coffee has roughly three times the amount as soda at about 135mg of caffeine, and eight-ounces of brewed tea has similar to a twelve-ounce soda at 50mg.
A twelve-ounce serving of an vigor drink has a caffeine content similar to that of the eight-ounce coffee - at nearby 120mg. Comparing these numbers can be deceiving because the amounts for the vigor drinks are often quoted in eight-ounce servings, whereas sodas are more often seen in 12-ounce servings. Red Bull is sold in a smaller, one-serving can, but other vigor drinks such as Rockstar or Monster are sold in large cans - so that the buyer is in fact taking in 2-3 servings if he drinks the whole can - thus bringing the caffeine intake even higher.
Many habitancy report anxious, jittery feelings of uneasiness after the consumption of more than 200mg of caffeine, and in fact by 400mg. Adverse effects associated with caffeine consumption close to 400 mg consist of nervousness, irritability, sleeplessness, increased urination, abnormal heart rhythms, and upset stomach.
Tracking your daily dose of caffeine can be tricky, as it is hard to know how much caffeine is in a given beverage, or even from one cup of coffee or tea to the next. But studies suggest just 100mg of caffeine, or the amount in a 6-ounce cup of coffee, are all that is needed for the median man to get a little boost.
Are they safe?
A study in 2004 found caffeine consumption in adolescents to be associated with elevated blood pressure. Therefore, the consumption of vigor drinks by children and adolescents is not recommended. Furthermore, vigor drinks, like soda, consist of added sugar, which also causes vigor levels to rapidly rise and then fall and should be little in a well-balanced diet.
Research has found consumption of caffeine prior to heavy rehearsal to be safe; however, the
safety of animated caffeine in compound with other herbal supplements found in vigor drinks prior to or while rehearsal has yet to be established. Until the safety of this institution can be established, consumption of vigor drinks prior to rehearsal by individuals of any age is not recommended.
