What is Caffeine?

Caffeine is a white crystalline xanthine. Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants. It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut.

Caffeine is an alkaloid; of which there are numerous compounds such as the methylanilines, with three distinguished compounds: caffeine, theophylline, and theobromine, found in guarana, kola nuts, coffee, tea, cocoa beans, mate and other plants. These compounds have different biochemical effects, and are present in different ratios in the different plant sources.

Caffeine is the most popular drug on the globe. Caffeine is a powerful stimulant to the Central Nervous System. Moderate use seems to be desirable by all, male and female; although excessive use can produce undesirable effects. Caffeine was discovered in 1820. In 1838, it was found that theine, a substance in tea, was identical to caffeine. Six or so caffeine containing plants are used more worldwide as a beverage than any other plants and herbal materials put together. The many caffeinated natural plants are are: Coffee, Tea, Kola, Cocoa, and Guarana.

How do Caffeine Works?

* In our brain there is a substance called 'adenosine' which will only work with specific adenosine receptors. Adenosine is responsible for the energy in our body. It connects to phosphates in order to become 'adenosine troposphere' or 'ATP'. ATP is the 'energy currency of all life, and it is by breaking the bond between adenosine and its phosphates that our body releases usable energy.

* When our adenosine bonds to the adenosine receptors in our brain then, that means there is none free in the brain and means that we have no energy from our brain and we therefore get tired.

* What caffeine does then is to bond with the adenosine receptors instead and this then means that they cannot take up the adenosine in the brain leaving more free energy in the brain and preventing us from getting drowsy.

* At the same time caffeine has another effect in that this action causes the pituitary gland to think there is an emergency and to therefore produce more adrenaline from the adrenal glands. Adrenaline is the hormone that is produced by our bodies as a result to threats and stressors. For example, if you saw a lion in the wild – you would start producing more adrenaline. Likewise, today if your boss starts shouting at you that results in more adrenaline being produced. This is called the fight or flight response and it means our metabolism speeds up which enables us to run faster and pump blood around the body faster. This gives us a spike in energy and performance then to deal with immediate problems, but also results in our body using up a lot of energy as it runs on overdrive and eventually crashing out.

* At the same time the pituitary glands also release dopamine. This is another chemical that has a lot of what we consider to be positive effects on the brain and the body. Dopamine is essential to the way that the brain regulates our movements. Without it we can't move at all, but with excessive amounts we will find that we twitch a lot and bob around. Restless leg syndrome and constant fidgeting can be considered signs of having too much dopamine in our body. This is why we get twitchy after drinking large amounts of caffeine. Too much of it will also cause the heart to fluctuate which can be dangerous if you have a weak heart or you have it in large excesses.

* Dopamine is also a neurotransmitter meaning that it is crucial for transferring information across synapses in the brain so that various brain areas can communicate with one another. This is highly important for memory, problem solving and motivation, and is why we can use caffeine when we are studying.

* Finally, dopamine is also used in making us feel reward and is one of our brain's 'feel good chemicals' that it uses to motivate us. Dopamine is released naturally as a reward for eating food and having sex and without dopamine we feel a lack of motivation and enjoyment – while high amounts of dopamine can leave us feeling highly optimistic and motivated and give us more enjoyment out of life. This is one reason that caffeine is also highly addictive.
