Omega 3 Use in Pyrrole Disorder Increases Inflammation

By Samantha Gilbert, FNC, CHNP, CNC     Last updated on October 22nd, 2021

The benefits of omega 3 fatty acids are well known: they protect from heart attack and stroke, regulate cholesterol triglyceride levels, and are healing to the brain and gut.

But omega 3 fatty acids are not for everyone, and they are actually inflammatory to individuals with Pyrrole disorder, also known as Pyroluria, Kryptopyrroles, and Mauve factor. This is a biochemical abnormality which occurs when the body creates and excretes too many pyrrole molecules in urine.

To learn more about Pyrrole disorder, listen to my podcast episode with Dr. Judith Bowman, co-founder of Mensah Medical.

What is Pyroluria (Pyrrole Disorder)?

Pyrrole disorder is a mood and stress disorder. Contrary to popular belief, it can be seen in anyone of any age. Symptoms are typically most evident in toddlers and teenagers who have not yet learned how to cope with the resulting behaviors this disorder creates. I believe this is where the term “terrible twos” comes from. Pyrrole disorder is the underlying cause in a variety of symptoms and disorders from stretch marks, light sensitivity, and nausea, to Multiple Sclerosis and Rapid Cycling Bipolar Disorder.

Pyrrole disorder is often genetically inherited, and I almost always see it when there is a history of family alcoholism and addiction coupled with anger and rage.

Pyrrole disorder is much more common than most people realize and sadly, the medical community does not recognize it. This means your doctor probably won’t know what it is or how to test for it.

Pyroluria Testing

Testing is simple using a kryptopyrrole test designed to find elevated kryptopyrroles in urine, determining the level of pyrroles the body excretes. The kryptopyrrole test and pyroluria have also been historically referred to as KPU, Kryptopyroluria, KP, HPL, Mauve factor, and Hydroxyhemopyrrolin-2-one (HPL) in medical literature.

What do Pyrrole Molecules Do?

Pyrrole molecules are constantly excreted in our urine and for the typical person, this is not a big deal. However, for someone with Pyrrole disorder, nutrient deficiencies occur because these molecules have an affinity for zinc and vitamin B6. They latch onto and excrete these molecules in urine before the body is able to absorb them.

Zinc and vitamin B6 are critical for a healthy immune system, maintaining intellectual function, mood, and memory to name a few.

Another feature of Pyrrole disorder is a deficiency in arachidonic acid (AA), a polyunsaturated omega 6 essential fatty acid (EFA). Unsaturated fatty acids are especially important because they provide fluidity to cell membranes and assist in communication between brain cells. Omega 6 EFAs are essential for normal growth and development, regulating metabolism, maintaining the reproductive system, skin and hair growth, as well as maintaining bone health.

Omega 6’s have gotten a bad reputation due to their abundance in junk foods and industrialized vegetable seed oils, which I don’t recommend. However, it is unfortunate that a one-sided view of them has led many people to think all of them are bad, which has resulted in extreme avoidance and, even worse, increased deficiencies.

Pyroluria Symptoms

Mental Health and Pyrrole Disorder

Common mood instability symptoms of Pyrrole disorder include:

  • High irritability and temper
  • Poor stress control
  • Severe mood swings
  • Tendency to withdraw socially
  • Pessimism
  • Explosive anger and rage
  • Anxiety
  • Depression

Disorders associated with Pyrrole disorder include:

  • Bipolar disorder (especially rapid cycling)
  • Autism
  • Schizophrenia
  • OCD
  • Disruptive Mood Dysregulation Disorder (DMDD)
  • Tourette’s syndrome
  • Multiple Sclerosis
  • Parkinson’s disease
  • Asperger syndrome
  • Alcoholism
  • Epilepsy
  • Down syndrome
  • Porphyria

Physical Health and Pyrrole Disorder

Physical signs of Pyrrole disorder include:

  • White spots on fingernails
  • A sweet or “fruity” breath
  • Poor wound healing
  • Frequent infections
  • Poor short term memory
  • Sensitivity to light, smell, sound, and textures
  • Lack of dream recall
  • Abdominal pain
  • Lack of hair on head, eyebrows and eyelashes
  • Blood sugar dysregulation
  • Lack of regular menstrual cycles
  • Abnormal body fat distribution
  • Acne
  • Loss of appetite (especially in the morning)
  • Low libido
  • Leaky gut
  • Malabsorption
  • Insomnia
  • Morning nausea
  • Pale and thin skin
  • More energy in the evening (after the sun goes down)
  • Poor tanning
  • Skin rashes
  • Joint pain
  • Spleen pain (side stitches when running)
  • Migraines
  • Upper jaw overcrowding
  • Sensitivity to supplements
  • Gut dysbiosis
  • Delayed puberty
  • Criminal behavior

Diet and nutrients are key for the pyroluric individual and must contain ample zinc and B6-rich proteins for calming and to balance blood sugar, plus high-quality omega 6 fatty acids. Leaky gut and malabsorption are commonly seen in those with Pyrrole disorder and must also be addressed for healing to occur.

I encourage you to not buy into the hype that all omega 6 fatty acids are bad. Industrialized vegetable oils such as canola, soy, and corn are not good choices, but this doesn’t make all omega 6 oils evil. Quite a few of them are very healing for those with Pyrrole disorder. My Pyroluria Cookbook contains the complete list along with more in-depth research and delicious recipes.

  1. Hi Sami, I am curious what you think of the test for pyroluria? I had one done by a reputable lab, followed all the correct procedures, and it came back negative, despite a high score on the self test.
    Thanks, Susan

    1. It is important to take the test sample in the late afternoon, preferably on a day when you are experiencing some stress. The body does not dump pyrroles evenly throughout the day, so it is entirely possible to have high pyrroles, but take the sample at the wrong time and test normal. Pyrrole excretion has also been found to vary widely from day to day. Also the sample can easily degrade, so proper handling (protect from light and keep frozen) is important in getting an an accurate result. I believe many people with high pyrroles take the test, get normal results, and go away thinking they don’t have pyrroluria when in fact they do. My first test result (sample taken early afternoon) was barely out of the normal range. When i tested again a year later (sample taken just before dinner) the result was extremely high! I’s worth redoing the test if you fit the profile. . . . . I eat a lot of fish. I wonder if that is a problem if i am taking plenty of P5P and zinc and keeping my pyrrole levels down? . . . . I found i couldn’t tolerate regular B6 but do very well on the activated form, P5P. Apparently many people have trouble activating and/or meatabolizing and getting rid of regular B6, so it either does no good and/or reaches toxic levels. . . . . When i first started on the P5P i could hardly believe how much better I felt, and how quickly.

      1. Great info Terry! I had recurrent bouts of psych issues after my baby was born for about 5 years. Horrible anxiety and fear with psychotic features. I had the same experience with the test, and was toxic on B6. Thanks for sharing that this is common. How helpful–I did not know and have been trying to connect the dots on this! When I recently started working with Sami we prioritized my supplements and got me on zinc and P5P. Wow. Feeling amazing…better all the time and so greatful!

    1. You are looking for high levels of GLA, so the two best choices are borage and evening primrose oil. Most people do better with one or the other. As far as i know the only way to find out is to try them. Personally i love borage oil but evening primrose makes me feel nauseous.

  2. Hi Samantha,

    Could you please advise of the research that indicates Omega 3’s increase inflammation in pyrolics, and which Omega’s you are referring to? As my understanding is that zinc isn’t a cofactor for the metabolism of Omega 3’s like fish oil whereas it is for ones like walnuts.

    1. Click on the links at the end of my post. #1 “Normally the desaturase enzymes which metabolize EFAs have a higher affinity for the n3 (Omega3) series. It has been proposed that in schizophrenia (as it pertains to Pyrrole disorder) mutant desaturases are present which prefer the n6 series. This change would account for the low levels of linoleic acid, dihomogammalinolenic acid and 1 series prostaglandins which have been reported in schizophrenia.” Emphasis mine. #2 “In pyroluric patients arachidonic acid (AA) was significantly decreased.”

      1. “It has been proposed…” That’s not research, that a hypothesis.

        Is there actually any research outside of Pfieffer and Walsh, etc., that shows that pyrrole disorder is a real condition?

      2. That was a quote from another paper, not Dr. Walsh. Dr. Walsh’s research has been approved of and endorsed by the American Psychiatric Association. Do you really think they would do so if it were bunk research? Pyrrole disorder is absolutely a real condition with the urine kryptopyrrole test providing accurate, clinical data with which to create treatment plans.

      3. It’s to bad that the AM. Psychiatric Association still only passes out SSRI’s for treatment. I’m almost 69 and for 25 yrs. was severely drugged for Bi-polar to the point of having serotonin toxcidity and a trip to ER. I slowly withdrew from huge doses of SSRI’s (which took 3 yrs) with the help of Ann Blake Tracy ( I have severe health issues now and was not healthy from childhood, including immune system and sleep issues. I have never heard of these conditions you speck of, but now believe that this condition and most likely over methylation describe me. I have developed widespread sensitivities to many foods and other things so eating has become difficult. I have been to 5 ND’s and the one now has helped me most. Acupuncture, homeopathic and neruo feedback help, but not long term and now I know reasons more. Going to share this with him, as he has never worked with anyone like me. Not sure if he knows testing for these things, but will contact you if need be. Thanks. P.S. is their a chart on foods with high and low histamine levels can print for changing what I eat.

    2. My son took part when Dr Walsh was investigating Omega 3 and Omega 6 EFA’s, and he had a very high Pyrrole count and he came back 50% below normal in Omega 6 as did all those with a high Pyrrole reading, compared to controls.
      Those people with a mental condition without a high Pyrrole count came back deficient in Omega 3 compared to Controls.

  3. So interesting that I’ve come across this article right now as I’ve been conscious of upping my omega 3 and added flax seed to my breakfast this morning, by 10am I started to become quite anxious and withdrawn.. It’s now 7pm and my chest is tight (anxiety) and I’ve got so much adrenaline and nervous energy about me.. I’ve done nothing different today bar the flax seeds..
    Thank you for this information! Different bodies need different things!!

      1. Thomas F. Pequignot

        Pyroluria which was high has been in the low normal position now for a year as tested by Direct Healthcare. Still be careful?

  4. My 8 y.o son (PD) didn’t do well on fish oil that was prescribed by a naturopath. Another 6 months later an integrative GP put him on EPO and he smashed the house and had absolute meltdowns for a week til we stopped it.

      1. Some people do better with either evening primrose oil or borage oil, and react negatively to the other. I never did well with EPO but really like borage oil.

      1. What effect does treating with B6 and zinc have on a pyrroluriac’s toleration of/need for omega 3’s and omega 6’s?

  5. Michele Marbelle

    I am on undermethylated Primer as a diagnosed woman with Pyrrole (bought on by trauma.)
    I have been taking 3 Flaxseed oil supplements daily. Exactly WHERE does a possible inflammation occur?

  6. Hi
    What are your reccomendations for pregnancy? I want to nourish my baby and try make sure i dont also give it pyrroluria. My dr has stopped my B6 and zinc, waiting for my metagenics pregnancy multi to turn up in the mail. Im week 6.
    Any advice would be great!
    Thank you
