Caffeine (1,3,7-trimethylxanthine) is classified as a mild stimulant and is the most widely consumed psychoactive substance in the world today (Koppelstaetter et al., 2010). It is found in many plant-based foods but is most commonly ingested in the form of tea and coffee (Ruxton, 2008). Additionally caffeine is comprised as an active ingredient in cola, chocolate, health food products such as guarana tablets, energy bars and drinks, over the counter and prescription medications (Nawrot et al., 2003) and even recently in chips. Although there is considerable variation in caffeine concentration depending on method of preparation, a cup of coffee supplies approximately 100mg of caffeine while tea provides 50mg of caffeine on average (Julien et al., 2008). Of people who habitually consume caffeine, the daily average intake is 200 – 500mg, which is ingested in approximately 50 - 100mg doses across the course of a day (Brice & Smith, 2002). Once ingested caffeine is rapidly absorbed across the wall of the gastrointestinal tract with plasma concentration levels peaking 60 to 90 minutes after ingestion (Julien et al., 2008).

...Vindication of Caffeine as Not Harmful The issue of whether people should avoid ingesting caffeine has joined the ranks of other such controversial topics as fast food consumption and sugar intake. While these other substances add caloric increases to a person’s diet, caffeine, in and of itself, does not. Caffeine has been scientifically proven a safe substance; it possesses many health benefits and does not qualify as an addictive substance. Caffeine appears to have been unfairly selected as the next health villain. What is there about caffeine to villainize? Is it fair to cast a shadow over the substance as being harmful to all simply because there is a minority population whose systems do not tolerate caffeine consumption well? This would be tantamount to saying that gluten is a dangerous substance because there are those with certain disorders, such as celiac disease, who have adverse reactions to its consumption. According to an article citing the National Library of Medicine (Other questions, 2003), there have been studies done related to caffeine in excess of 19,000 times by various scientific entities. In all of these studies, there has not been enough compelling evidence to convince the Food and Drug Administration to issue anything other than “generally considered as safe” (Other question, 2003, p. 1) in regards to caffeine consumption. There are some sources, such as Carolyn’s Herbal Information (2003), touting the poisoning effect that caffeine can have on a...

The author of Energy Drinks Promise Edge, But Experts Say Proof is Scant supports the claim in many ways by stating various facts about the research done by experts on energy drinks. Such as the energy drink industry being in scrutiny by the Food and Drug Administration after various reports of serious injuries or even death that could very well be linked to the amount of caffeine in the drinks. The research that has been done on energy drinks always ends up leading to the conclusion that there are no real benefits besides a short burst of energy. Energy drinks tend to be very hyped up, like “Red Bull gives you wings,” and Rockstar is “scientifically formulated”...

...root beer, grape soda and cranberry, which are packed with sugars without the guilt. XS is also ideal for those who want an energy kick without the caffeine. BRAND STORY: At XS, we wanted to make a drink that tasted great with a wide variety of flavors, and one that delivered a better function than other energy drinks on the market. Its formulation is what makes it special. It has folic acid, more vitamin C per ounce than orange juice, a boost of B vitamins and a formulation of herbs. Precall planning involved observing the energy drink companies already in the market such as Red Bull, Booster and Monster. Their product formula, approach and their distribution channels were completely different from XS. We knew sales could do as good as they have because we offered consumers variety and a personal selling approach through Amway’s independent business owners. Interest: Presentation involved introducing potential consumers to XS and its many varieties and what distinguishes it from Red Bull and other energy drinks. We used the features-benefits approach when talking about the different flavors it comes in and its health benefits. Desire: For demonstration: we let consumers try the extraordinary varieties to the energy drink category like root beer, reminded them that the product is sugar free and comes in tea and soda flavors and caffeine free varieties too. We let them realize that it’s surprising that XS delivers excellent flavor without...

...Product Description In December of 2011, 14 year old Anais Fournier purchased and consumed two 24 oz Monster Energy drinks within one 24 hour period. This is the equivalent of 6 servings for an adult. She went into cardiac arrest the night of December 17th and died the evening of December 18th. Her parents sue Monster for damages on the basis of Strict Liability and Negligence. Monster is sold as dietary supplements instead of food item, so it is not as strictly regulated. It is marketed as a supplement that increases energy, promotes focus, and helps with weight loss. The drink contains an excessive amount of caffeine and other drugs that combine to increase heart rate, body temperature, and neural stimulation. Two 24 oz servings of Monster is above a safe dose of caffeine for most bodily demographics. Within 15 minutes of consumption the effects of the caffeine kick in. Due to increased neural sensitivity and dehydration, painful headaches are very common. 24 oz of Monster is also a lot of liquid to drink. Drinking 12 oz causes most people discomfort and would cause a reasonable person to stop drinking. The body naturally feels the danger because it is under a lot of stress from the beverage. For most reasonable people this bodily danger is obvious. Despite this physical discomfort, many people continue to abuse Monster. Thousands have ended up in the ER, and tragically there have been over 5 fatalities involving Monster. Comparison to McDonald's Hot Coffee Case In the...
