Fibromyalgia and Aspartame

fibromyalgia and aspartame

Aspartame is an artificial sweetener that is calorie-free. The safety of aspartame has long been a controversial topic in the medical world. Although several studies show that aspartame is safe for consumption, there is evidence of its potential link to fibromyalgia. In fact, aspartame is also link to other chronic conditions.

Safety of Aspartame

Aspartame is one of the six artificial sweeteners approved for use by US FDA. The sweeteners have a sweetening capacity that is several times sweeter than sugar. FDA reviewed each sweetener thoroughly especially in terms of health safety. In fact, the safety testing gone beyond the required testing level for food additives, according to a study published in Regulatory Toxicology and Pharmacology. Authors of the article concluded that the aspartame is safe for everyone to consume.

Evidences on The Link of Aspartame and Fibromyalgia

There is no existing study done to determine if aspartame can trigger fibromyalgia. However, a 2010 article published in the Clinical and Experimental Rheumatology, reported two different cases. These cases were reports on two individuals who had fibromyalgia and whose symptoms had vanished after they stopped consuming aspartame.

One of the cases follows a 50 year old woman who suffered from fibromyalgia for more than 10 years. She went on a vacation for several days without taking any aspartame. During her vacation, her fibromyalgia symptoms were nonexistent. Thereafter, she decided to totally remove aspartame from her diet. After which, she saw complete regression of all her fibro symptoms.

The other case followed a 43 year old man who shared similar experience. He saw complete regression of his fibro symptoms after he decided to stop taking aspartame.

Eliminating Aspartame for Fibromyalgia Patients

Since the cause of fibromyalgia is not known, the manner by which these individuals experienced regression of symptoms can only be speculated. Yet, many believe that fibro patients can benefit from eliminating aspartame from their diet. The potential benefit of eliminating this sweetener from their diet can be reduction of symptoms. This is not only applicable to those suffering from fibromyalgia but also people with other chronic diseases.

Nevertheless, some experts believe that doctors should consider asking their fibro patients if they consume aspartame. This could be a lead to the cause of this mysterious condition.


  • I stopped using aspartame or anything it was in years ago. I only use stevia and raw honey to sweeten my tea or coffee now. I never noticed any change in my Fibromyalgia. Also, I believe aspartame is sold under the name Equal, for one, not Splenda. Splenda is a whole other problem.

  • Why show Splenda in an article about aspartame? Splenda is not, nor does it contain aspartame. You should be showing packets of Equal.

    • Sandra, you are so correct regarding your statement! I have been using Splenda for the reason that aspartame is not in it! Good for you for catching that … l was questioning myself when l saw the pic of Splenda!!!!!

  • First, your graphic is showing Splenda – in yellow packets – NOT Nutrasweet which is BLUE packets. BLUE packaged aspartame is ALSO sometimes found in medications as well. (In my case it was in a generic blood pressure medication)

    Splenda is Sucralose – not quite as bad as Nutrasweet/aspartame but not as good as Stevia (green packets) which is all natural.

    I get even one tiny drop of nutrasweet/aspartame – I get the equivalent of a 3 day migraine. Others, may break out in hives or other reaction. I’ve noticed no reaction to Splenda or Stevia.

    I’ve suspected Fibro since my 20’s – but not diagnosed formally until latter 40’s. After digging back in medical history, Dr.’s decided probably born with Fibro as I was symptomatic since birth, as was one of my daughters. Have never found a connection from food to my Fibro. And I’ve tried lots of combos – it’s how I figured out the issue with nutrasweet/aspartame. NOTE – most Dr.’s are NOT up to speed on aspartame. If you are allergic, like I am – just have the nurse enter it when they weigh you in, and also tell your pharmacy.

  • Splenda is an artficial sweetner very similar to aspartame. I have been off of aspartame 11months now. I have noticed there is a big difference in pain. But I also have arthritist. But pain is still there not as bad but I have changed my diet to eating foods that help with inflammation.

  • I was diagnosed with Fibromyalgia in 2002, I find any artificial sweeteners intolerable but especially aspartame.
    Sweeteners I can use pure stevia, honey, real maple syrup.
    I recently read an article about dairy products, which I love and can’t eat without negative side effects, stating the pasteurization process creates a problem for fibromyalgia folks, so I am on the hunt for raw milk and cheese and butter.

  • I was diagnosed with fibro ack in either 2000 or 2001 I had no clue about aspertame but when a friend told me about it I started researching it then my daughter started waving severe pain in her knees doctor did not know why my daughter also at the time was drinking a lot of diet soda which has aspertame I made her stop it the knee pain stopped after being off of it for awhile both of us now read every label on food drink snacks etc before buying them

  • I was dx in 98 with fibro. Present day, my Dr has put me on Gabapentin to supposedly help me ease off pain meds. I’ve noticed taking Gabapentin n Diet Coke made me sort of stutter, maybe some kind of jerking in my jaw also affecting my speech. Iced tea with artificial sweetener the same so for me to take Gabapentin I must not have anything with aspartame. Has anyone else noticed anything with the same connection? Or is it just me?

  • The FDA allows so much in the American diet that is unhealthy. Aspartame being one of them. I quit drinking or eating anything with aspartame in it years ago when I found this out.

  • I have had fibro for the last 7 years and have never touched aspartame. I believe I had back in my late 20’s but did not realize it was fibro. I have been against using aspartame for years because my boy friend was drinking diet pop all the time. Sorry it is not the case with me.
