There aren’t many people who can get through their mornings without some form of a caffeine-infused drink. Whether your vice is coffee, tea or energy drinks, we’re all fans of the magical effect of caffeine. But for this intolerant to caffeine, it’s a different story. It ruins their mornings and wreaks havoc in their digestive tract. What’s worse is that the symptoms of intolerance are so similar to other conditions and illnesses that it often goes unidentified. Making the problem persist.

Symptoms of Caffeine Intolerance

You might be surprised at how common a caffeine intolerance is. A significant issue with caffeine intolerance is that the symptoms are often mistaken for withdrawal, which is a great excuse to get the kettle boiling. Here are a few of the common symptoms;


If your mid-morning coffee makes you anxious or jittery, it might be caused by an intolerance to the caffeine. Whether short-lived or constant, jitters after a warm cuppa aren’t a good sign.

Headache or Migraine

This is a clear sign that somethings wrong. If headaches routinely follow a caffeinated beverage, whether blinding or dull, it’s a sign that you might be intolerant to the substance. Keep in mind, that caffeine is a psychoactive substance, so when you’re head is complaining about it, you’re better off listening to it.


Now, if you downed a can of Redbull at 8 pm and are struggling to sleep  – that’s just unwise. But if you’re withdrawing from caffeine from 2 pm and still can’t get to sleep at a reasonable hour, then you could be intolerant to caffeine. Keep an eye out though, as many desserts can have hidden caffeine, especially anything with chocolate!

Intolerance or Over-Consumption?

Remember, no-one is immune to the effects of caffeine. So, anyone who has well over 400mg in a single day is likely to experience adverse reactions. So just because you aren’t intolerant, doesn’t mean you should go crazy and have numerous espresso shots this afternoon. Listen to your body, and if you recognise the above symptoms, it’d be a good idea to get yourself tested for caffeine intolerance.
