According to an American study entitled “Beverage caffeine intakes in the U.S” an espresso contains 75mg of caffeine only 5mg less than a ‘Red Bull style energy drink’. While a cup of drip-filter coffee contains a whopping 145 milligrams of caffeine. What about all the tea drinkers out there? Well the study shows that your one-minute brew of a generic black tea contains almost 60mg.

So how much caffeine is too much?

Outside of the jittery addicts screaming the necessity of the caffeine based diet, is there a correct figure? According to the Mayo Clinic you shouldn’t regularly exceed 400mg of caffeine. Their assessments of the caffeine content however appear to be quite different calling this magic figure 4 cups of brewed coffee or 2 ‘energy’ shot drinks.

What are the negative effects of caffeine?

Many of the negative effects of heavy daily caffeine consumption are fairly obvious such as insomnia, raised heart-rate and restlessness. Caffeine has also be linked to nervousness and irritability as well as muscle tremors. A less known side-effect is the upset stomach and also muscle cramps.
These effects are all very reliant on the individual, things like age, health and body mass as well as tolerance all play a huge role in how much is recommended and the possible side effects.

If you are interested to know how caffeine is affecting your sleep then you should try the UPCoffee App from Jawbone that helps you keep track of your caffeine consumption and using a few details about yourself to workout roughly how this will be effecting your sleep. I tried it recently and was amazed by how much more caffeine I was having than I thought. The only flaw is that measurements are in fluid ounces so it takes a second of mental arithmetic to translate, not so difficult when you’re jacked up on caffeine. (1 US fluid ounce = 29.5 ml)
The more scientific among you might want to pair it with the Up wristband which tracks sleep movements and activity during the day and syncs it with your smartphone app, but maybe that’s a bit more information than you need.

    This was very interesting to read. I love drinking my filter coffee , but I always make sure to drink it in moderation no matter how much I love it. Anything done in moderation is always good.
