Upon ingestion, caffeine connects with adenosine. Adenosine is a compound that builds up throughout the day and “runs” through your brain 's receptors, making you weary. Caffeine is similar to adenosine in structure and will work its way through the bloodstream into the brain. Once entering the brain, adenosine and caffeine compete and combine. Caffeine then takes over adenosines job and replaces your weariness with energy. Caffeine does not only affect the brain. Some side affects of gaining adrenaline include increased heart rate, opening up of airways, and reabsorption in the brain, which makes you feel happy and gets your blood pumping (Bundey). (5)

(7) When it comes to knowing how much caffeine the body can handle, it is gauged on the brain development and body type. Healthy adults can drink 300 to 400 mg of caffeine daily. Children 's intake of caffeine should be limited because their brains are still developing and bodies are still growing and caffeine could possibly interfere with both. If a child is to use caffeine, a moderate amount of it is recommended. A teenager should only take 100mg of caffeine every six hours, because they are still in the process of growth and brain development is crucial at this age (Noel) (8)

Ephedrine and caffeine work individually and as a combination when ingested into the body (http://www.endureplus.com/caffeine_ephedrine.htm). Caffeine has properties that stimulate the central nervous system and the energy metabolism in the peripheral tissues. These stimulations can cause four other reactions: adenosine receptor blockage, improved neuromuscular transmission, increased muscle contractility, and increased adrenalin levels. Ephedrine also stimulates parts of the central nervous system and the peripheral tissues known as the adrenergic receptors. Essentially ephedrine can act like adrenalin in the body so a person’s energy level increases also. The effect of the combination of ephedrine and caffeine is best described as promoting thermogenesis (http://www.lef.org/magazine/mag98/dec98_heat.html). Thermogenesis is the “chemical production of heat within the body to promote the oxid...
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it.

Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s.

Although individuals try to stop using caffeine, some cannot because it has a strong hold on them and some people can stop.

In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings.

A study of 100 US children, 12-18 years old shows that 73% have more than 100mg of caffeine everyday (Is Your Teen). That is the equivalent of four cups of coffee or two energy drinks. Though there is no official amount doctors say is safe, most agree that children and teenagers should have less than 100mg.
