The idea of energy shots started decades ago in Japan, where small “tonics” became very popular among consumers, served highly concentrated and without carbonation. With the introduction of energy drinks as of the late 1980s, the efficacy of these energy shots started to travel the world as a new product format. In 2003, the founder of 5-Hour Energy discovered an energy drink at a natural products trade show and formulated a similar product reducing the content from 16 to 2 ounces but keeping the energizing effects. By 2008, there were over 25 brands offering energy shots in the US alone. In 2009, a major energy drink producer Red Bull launched an energy shot. By 2011, energy shots became so popular that 5-Hour Energy sold $1 billion of their product at retail. Although originally marketed in the US, energy shots are also becoming popular in other parts of the world, such as Europe, Asia and Australia. The products are aimed at customers who seek high efficacy with little liquid intake, and include truck drivers and students.

Energy Shots and DrinksEnergy shots are a specialized kind of energy drink that contain a dose of the stimulant caffeine in a small amount of liquid. Whereas most energy drinks are sold in cans or bottles, energy shots are usually sold in 50ml bottles. Energy shots can contain the same total amount of caffeine, vitamins or other functional ingredients as their larger versions, and may be considered concentrated forms of energy drinks. “Micro shot” energy drinks also exist, containing only 1- 5 teaspoons of liquid. Similar to energy drinks, energy shots contain caffeine, vitamins, and herbs such as guarana, ginseng or ginkgo biloba, taurine, maltodextrin, inositol, carnitine, creatine or glucuronolactone. some energy shots contain sugar however, many brands also offer artificially-sweetened ‘diet’ versions. Some decaf varieties are also offered. The central ingredient in most energy shots is caffeine, the same stimulant found in coffee or tea. Vitamin based energy shots contain numerous additional vitamins and supplements for sustenance, sustainment, and overall health. 5-Hour contains vitamin levels sometimes hundreds of times higher than the recommended RDA. Some energy shots include electrolytes, and others include a selection of vitamins. The average 50ml energy shot has about 80 mg of caffeine. This is approximately equivalent to a cup of coffee. As of June 2oo9, there were approximately 250 energy shot brands in the US.  5-Hour Energy owned 90% of the market share in 2011, according to research firm of Symphony IRI. Some of the manufacturers of energy shots also market energy drinks, however, crossover success has not been common for the larger brands such as Monster and Rockstar, Red Bull, the category leader of the energy drink category, launched an energy shot of its own in April 2009.

The functional ingredients of energy shots are comparable to those of energy drinks, and their effects on improvement in mental and cognitive performances and subjective alertness are in line with the effects of traditional energy drinks. Vitamin based energy shots have variable benefits dependent on the additional ingredients. Energy shots share most of the advantages of the energy drinks such as helping to fight fatigue, heightening mental awareness, convenience of being available readily, and affordability for the regular Joe.


– Calories: The calorie count in sugar free energy shots is a lot less than that of energy drinks. A sugar free two ounce shot has only 0-4 calories while a generic sugar-free energy drink has 100 calories.

– Caffeine: The shots tend to have about as much caffeine as regular energy drinks, and it’s the caffeine that provides most of the kick, experts say. Because of that, nutritionists urge caution, especially for those who also drink coffee or other caffeinated drinks. Both generally provide the same amount of caffeine as a cup of coffee.

Staying away from energy shot maybe the healthiest choice, but not necessarily realistic. When one has a chronic problem with fatigue, there is something wrong with the body and no energy drink or shot is going to cure that, it is recommended to see a doctor. Energy shot has the same effects as the drink, has fewer calories and is more portable. Energy shot come in a 50 ml (roughly 2 fluid ounces) bottle which can be consumed in one quick gulp. Most energy drinks contain caffeine, about eighty milligrams worth and also contain other ingredients like guarana, ginseng or ginkgo biloba, taurine, maltodextrin, inositol, carnitine, creatine, and glucuronolactone. A large percentage of these ingredients are vitamins and mineral supplements that are in concentrated form. If one check the RDA on the bottle, one will find that many of them are present at LOOo/o or greater. The full size version energy drink and the label on the much smaller energy shot both contain roughly the same amount of each ingredient. Think about it. You can get eighty milligrams of caffeine in a small fifty milliliter bottle. That’s the same as what you get in a standard cup of coffee and it will take you a lot less time to drink. If you’re looking for that extra boost in a small container, the energy shot could be the solution.

Energy Shots and DrinksThe sugar-free shots are not only portable but also lower in calories than most energy drinks. The 2-ounce 5-Hour Energy shot, which is artificially sweetened, has 4 calories. A regular 8-ounce Red Bull energy drink, by comparison, has 100 calories, and a sugar-free Red Bull has 10 calories. Specifically, too much caffeine can cause nervousness, trouble sleeping, nausea, vomiting, rapid heartbeats, and higher blood pressure. Many makers of energy shots say children and those who are pregnant, nursing, or sensitive to caffeine should avoid the beverages. 5-Hour Energy advises no more than two bottles a day.


The Tweak Extreme Berry flavor tastes like a sweet and sour fruit candy with a purple-pink color. It’s easy to consume quickly, but the berry aftertaste is far less pleasant than the beverage itself. It’s less bitter than Red Bull, but falls short of Monster’s sweetness. Before drinking Tweak Extreme, from a research baseline as set of vitals were recorded. Readings were blood pressure of 126 over 85 and a pulse of 82. Ignoring the two serving limit, after over 30 minutes of taking Tweak Extreme, vitals were reassessed, blood pressure jumped to 146 over 90 with a pulse of 122 beats per minute. With the elevated vitals came full-body-jitters, sweat, jumpiness, dry mouth, stomach discomfort, hot flashes and an inability to sit still. The accepted normal blood pressure for adults is 120 over 80 with a pulse rate of 60 to 100 beats per minute.

The manufacturer properly combine 223 mg of active ingredients: Caffeine, a stimulant, Evodiamine, which raises body temperature, N-Acetyl-L-Tyrosine, an amino acid that converts into a variety of hormones, Yerba Mate, a stimulant, Oriental Ginseng Root Extract, a stimulant, Vinpocetine, which increases blood flow, Yohimbe HCL, a sexual stimulant, and Green Tea Extract, an anti-oxidant and stimulant. The known side effects of these ingredients come mostly from anecdotal sources. Tweak Extreme charges past the normal into ridiculous. Not surprising, considering the word “tweaking” is slang for the effects of crystal meth, and meth users are often called “tweakers.”


Street King Energy Shot is an extra-strength energy shot with an extreme amount of caffeine. It was originally developed by rapper, 50cent and launched in 2012 before being acquired by PureGrowth. Jackson partnered with Pure Growth Partners’ Founder and CEO Chris Clarke to launch the product, which through the United Nations World Food Programme (WFP) provides a meal for a child in Africa with each shot purchased. The product is manufactured and distributed by Street King LLC in New York, NY. The drink is sold in 74-millilitre (2.5 US fl oz) shots which contain a caffeine amount of 285 mg comparable to that of 2-3 cups of coffee. Street King is available in orange-mango and grape. Street King states that they have left out “common, controversial industry ingredients like taurine, guarana and ginseng”‘ SK Energy Shot has 4 flavors; Berry, Grape, Pomegranate and Strawberry Lemonade. All flavors are sugar-free and sweetened with Sucralose and Ace-K.


Energy ShotsMonster and Rockstar are brightly-labeled beverages that contain 150 to 175 milligrams of caffeine in drink sizes ranging from 5 to 16 fluid ounces. That’s about three-to-five times the amount of caffeine in 12-ounce serving of a typical mass-marketed soda. The more concentrated 5-hour Energy doesn’t list its caffeine content but consumer Reports recently determined that it contains 215 milligrams of caffeine per 2 fl. oz. bottle (the “extra strength” only contains a bit more at 242 milligrams).

They also contain various combinations of vitamins and amino acids, with some vitamins far exceeding recommended daily values. Among all of these components, phenylalanine is most concerned about, an amino acid that cannot be adequately broken down by people with a genetic disorder called phenylketonuria. Main reason sodas containing the artificial sweetener aspartame listed with a warning for phenylketonurics that aspartame contains phenylalanine. In such individuals, the amino acid gets converted instead to a chemical that can cause seizures, and even mental retardation in developing infants and children. Phenylketonuria is rather common in the US, occurring in 1 out of 15,000 people but is three-to-five times more common in Turkey and Scotland.
