But what happens when a “little” boost just isn’t enough? Is there anything with a bit more kick?

What is caffeine and how does it work?
Caffeine is a psychoactive drug – that’s the same as things like amphetamines and cocaine – so before we talk about how to ingest more of it, let’s look more closely at what it is and how it works. That way, you’ll have the information you need to stay safe while you’re drinking your coffee.
Caffeine is considered the world’s most commonly used psychoactive drug (1) – but unlike many others, it is completely legal in most countries. For most people, caffeine comes from coffee, but it is also found in tea and some soft drinks like cola. It is also a common ingredient in some diet pills.
The familiar buzz so many of us enjoy that comes from drinking coffee is a result of caffeine stimulating the central nervous system, thereby increasing heart rate and blood flow.
This makes us feel more awake, more alert, able to concentrate better and even allows us to perform better in stamina-based exercise (2).
It does this by binding itself to adenosine receptors in the brain, blocking the signals that tell your body to relax and prepare for sleep.

The good effects and the bad
This shot of extra energy and alertness is the effect that most people use caffeine to obtain, either to wake up in the morning or perhaps to stay awake longer into the night for study or to meet work deadlines.
Increasingly, studies are showing that regular caffeine intake – within certain limits – has many health benefits. These may include helping to prevent some cancers, helping to prevent Parkinson’s and Alzheimer’s diseases, helping to prevent type II diabetes, and many more.
Contrary to a commonly held belief, caffeine doesn’t cause high blood pressure. It does cause a short-term spike in blood pressure immediately after consumption, but this effect becomes less pronounced in regular coffee drinkers (or those who regularly ingest caffeine in other forms).
However, on the other hand, ingesting too much caffeine in one go can have unpleasant side-effects. These may include feeling jittery, the inability to sleep, restlessness or nervousness. If you begin to experience any of these symptoms, it may be a sign you need to consider cutting down.
In very high doses, caffeine can also be toxic. While you would probably need to drink around 50 cups of coffee to reach dangerous levels of toxicity, deaths from caffeine overdose from only a few highly-caffeinated beverages have been recorded in extremely sensitive individuals.
The best advice is to enjoy coffee and caffeine in moderation – but unless you are very sensitive to caffeine, there is no need to give it up completely.

How much is safe?
The answer to this question depends on who you speak to, and different authorities give slightly different figures.
Some would suggest no more than 400mg per day is a safe guideline to stick to; others suggest a slightly higher figure of up to 600mg per day.
Again, even if you do slightly exceed these recommendations, you will probably suffer no more than a little jitteriness and a touch of insomnia; remember, caffeine can take from four to seven hours to leave your system.
How much caffeine is in coffee?
If you are trying to monitor – or even increase – your caffeine intake, it is important to know the caffeine content of a particular drink.
Unfortunately, there can be some quite a significant variation depending on a combination of several factors.
Major factors include the type of coffee used (robusta beans contain roughly twice the caffeine of arabica), the brewing method, the brewing time, the grind, the water temperature and, of course, the amount of coffee used.
For this reason, it is impossible to give a definitive answer as to how much caffeine there is per cup. That said, here are some rough figures:
- Drip/filter: 115-175mg/8oz serving
- French press: 80-135mg/8oz serving
- Percolator: 64-272mg/8oz serving
- Turkish/Greek: 160-240mg/8oz serving
- Instant: 57mg/8oz serving
- Decaf (brewed): 5.6mg/8oz serving
- Decaf (instant): 2.5mg/8oz serving
- Espresso: 64mg/1oz shot (but can vary enormously)
As can be seen from this list, a wide range is possible, more so with some brewing methods than others.
As a general, very approximate, the rule of thumb, a cup of coffee contains around 100mg of caffeine and the recommended daily intake is about 500mg. This means you can safely drink around five regular cups of coffee per day.
If you are drinking high-caffeine coffees, you may consider drinking fewer cups per day to stay within healthy limits.
Note also that decaf is not completely caffeine free – after the decaffeination process, a certain amount of caffeine still remains in the coffee, albeit in much lower quantities.
