Some time ago, we published a short post about the possibility of allergic reactions to caffeine.
That post received hundreds of comments from those who claimed to have experienced some type of adverse reaction to caffeine.
We have painstakingly sifted through all those comments, compiling the top 20 caffeine allergic reactions in order from most common to least common.
In most cases, these symptoms were reported after only a moderate amount of caffeine through coffee, tea, soda and / or energy drinks.

Is this Scientific Evidence?
At least one scientific study has shown that people have anaphylactic reactions to caffeine and is confirmed by a skin prick test. one
There is evidence regarding the inability to process caffeine as some people lack the genes responsible for this or the genes they are not being expressed as they should be. This allows caffeine to build up in a person's body rather than being broken down properly. These people are described as hypersensitive to caffeine. two
The above data is based on anecdotal evidence, so do not take it as gospel or scientific, but rather consider these caffeine allergy symptoms as possible since they were reported by a large number of people. If a person suspects a caffeine allergy, he / she should cease caffeine immediately and then assess as to whether it is indeed the caffeine. The symptoms should subside after caffeine is eliminated.
There is a fine line between what would be called caffeine sensitivity and what would be called caffeine allergy, but overall we are dealing with the body not being able to correctly process the caffeine molecule, whether or not it is called sensitivity or allergy is up for debate .
Most people who commented on the original article reported several of the above symptoms and some of the caffeine allergy symptoms were quite bizarre. The symptoms that were the strangest included itchy ears & anus suffered by one poor soul and a sweaty butt crack reported by another ...
Caffeine allergy has also been linked to a form of ADD and dementia in adults. The claim is that caffeine-induced anaphylaxis impairs people's ability to concentrate and remember things.
Could It Be Mycotoxins?
Mycotoxins are chemicals produced by fungi and they can produce all kinds of negative reactions when ingested by humans. A recent study 3 from the University of Valencia in Spain found that commercially sold coffee is often contaminated with mycotoxins. They've identified 18 different mycotoxins that are commonly found in coffee and found that the levels in decaffeinated coffee are often higher than that of regular coffee.
If you have a reaction to coffee but not other caffeinated products, there is a good chance that you are sensitive to mycotoxins and not the caffeine.
