What is Caffeine?

Caffeine is the world’s most popular drug. People pay more for 12 oz of coffee than a litre of fuel, which today is roughly £1.11 per litre of petrol. It is plant product that is most commonly found in coffee beans, tea leafs, soft drinks and even chocolate. The Food and Drugs Administration (FDA) in defines caffeine as both a food additive and drug. Extracted Caffeine by itself is a bitter white powder.

How caffeine works?


It tricks your brain into thinking that you are not tired. The chemical name for caffeine is 1,3,7-trimethylxanthine. Those who are chemist will know that it is structurally similar to adenosine, which binds onto receptors in the brain to make us feel sleepy. Caffeine blocks those receptors, preventing adenosine from working its magic. Therefore instead of having a calming affect, caffeine stimulates the brain, causing increase in heart rate, blood pressure, alertness and delay in onset of fatigue.

After 30 minutes of drinking caffeine, the dose of caffeine is at its highest in your blood, with a half-life of 6 hours. This means after 6 hours you still have half the original amount in your body.

Is Caffeine Addictive?

Caffeine may feel addictive however it is not classed as an addiction. It is merely a habit and does not activate the brain-reward circuit, which most addictions do. Going cold-turkey on caffeine will not give you the withdrawal symptoms as other drugs like nicotine. Headaches and moodiness may develop, but these symptoms should disappear after a day or two.

Can I Overdose On Caffeine?

Thankfully the answer is no. However, doctors recommend that the average person keeps their limit to below two 12 oz cups of coffee or 300 mg per day. In comparison, certain energy drinks will contain 80 mg of caffeine. You would most likely feel sick from drinking so much than overdosing. So there is nothing to worry about.
