I’m no fan of the artificial sweetener aspartame. Not only is there no good evidence that artificial sweeteners aid weight control, there is also evidence linking aspartame to adverse effects on health.
For example, aspartame liberates methanol into the body which can be converted to formaldehyde (used to preserve dead bodies), which has recently been added to the official ‘cancer-causing’ list of chemicals in the US. Animal work shows that aspartame at permitted levels increases the risk of several types of cancer.
I recently came across a piece in a rheumatology journal which describes what appears to be aspartame’s ability to induce fibromyalgia. This condition is characterised by pain and tenderness in the muscles. The paper describes two ‘case studies’ in whom fibromyalgia appears to be caused by ingestion of aspartame.
Studies have linked muscle pain and aspartame
The first of these concerns a 50-year-old woman who symptoms of fibromyalgia (more than 10 years standing) evaporated on holiday when not consuming aspartame. The symptoms returned when she came home and resumed aspartame use, but resolved again once the aspartame was stopped once more.
I have twice been told by individuals with fibromyalgia that their symptoms have resolved when on holiday. The first thing I think about here is sunshine and vitamin D, because vitamin D deficiency can cause muscle pain, and boosting vitamin D does seem to have the capacity to resolve this symptom. See here for a relevant blog post about this.
It is possible that in this woman’s case, sunlight and other factors had something to do with the resolution of her symptoms while abroad. However, the fact that her symptoms resolved on exclusion of aspartame strongly suggests this substance was the primary cause of her symptoms.
The second case described in the article was a 43-year-old man who had suffered with pain in his neck, forearms, wrists and hands for 3 years. Removing aspartame from his diet resolved his symptoms.
Case studies such as these don’t prove that these individuals’ symptoms were due to aspartame – it is possible that their improvement was due to the placebo response and the recurrence of symptoms due to what is called the ‘nocebo’ response (like the placebo response, but when the response is negative rather than positive).
Don’t dismiss the link between muscle pain & this artificial sweetener
However, observations such as these can be the start of advancement in our understanding of the effect of treatments and, in my view, should not be dismissed.
Certainly, should I see an individual suffering from generalized pain and fibromyalgia in the future, I’ll be making doubly sure I ask about their consumption of aspartame, and will be advising them to stop it as a matter of course.
Bearing in mind the fact that there is no good evidence that aspartame has benefits for health, such individuals will have nothing to lose by eliminating it, other than perhaps their ‘unexplained’ symptoms.

So, two people out of 320 million is consensus? sort of like salt causes high blood pressure!,, which it does not!
I had been using SPLENDA for 2+years and began experiencing increasingly worrisome &sharp pain in my head when sneezing, yawning, or coughing. I read an article that proposed various symptoms for popular artificial sweetners and my symptoms were there. I quit using SPLENDA and replaced it with STEVIA (natural product) – I am type 2 diabetic. The pain was significantly reduced within a week and gone in 2 weeks -that was a year ago – no further problems.
I became very afraid of aspartame after reading all the horror articles about it and eventually gave up all diet sodas that I had been drinking for 30 years with it in them. Also quit using Equal in coffee or anything else. Will not buy any drink with aspartame in it. Haven’t seen any improvement in my memory, but my muscles have hurt for a long time (not formally diagnosed as fibromyalgia, but I wondered), and they are not as sore as they used to be, though still hurt some.
I was using Equal and had the worst pain in my legs especially at night time when sleeping – possibly similar to restless leg syndrome – I quit using Equal and all pain has stopped and not returned – I also am trying to quit sugar and have used Stevia with no side effects – You are what you eat////make that change and stop all your diet drinks
Hi Bill,
Thanks for sharing your story! We’ve heard many others very similar to yours.

In my clinical practice, I have found a connection between some cases of back pain and the artificial sweeteners, Sucralose and Acesulfame Potassium. Over time, I have seen more than eighty patients who have shown clinical signs that indicate these sweeteners as the cause of their particular cases of aggravating and unrelenting pain.
Read ALL labels to be sure they are not in your diet and rid yourself of a possible cause of back pain. My patients found relief and you may too!
