Before I delve at length into the amazing process of methylation and its impact on personality and mental health, I'll lay some groundwork. For those who don't need or want such background, I've tried to make it easy for you to hit the highlights or jump ahead to your own starting point.
GENETICS
Genetics is basically the study of how parents pass some of their characteristics to their children. Genes are the units by which this occurs. The job of a gene is to make a specific protein. We have two of each gene - one from our mother and one from our father. Every cell in the body has the same genes, but only some of those are used/expressed in each cell. This selective expression is what allows our brain to be a brain and our liver to be a liver and not the other way around. Despite our incredible diversity, we all generally have the same genes as others of our same sex. We are only about 0.1% different from one another. SNPs or Single Nucleotide Polymorphisms are genetic mutations that developed over thousands of years. Of more than 10 million SNPs identified in the human genome, most of us have more than (but closer) to one thousand. Those that are expressed explain some of our differences including our unique vulnerabilities to certain health conditions. If you’ve ever looked at your SNPs, this can be a bit frightening. For many, doing so can cause more harm than good. Most of these mutations or SNPs are never expressed and have no significant effect. Walking around thinking you are destined for a serious or fatal health condition when you're not, can be a problem. EPIGENETICS Until recently we believed our genes and mutations were written in stone. We now know that during pregnancy, chemical bookmarks (methyl groups) can attach to DNA to enhance or inhibit gene expression in each tissue. Environmental insults in utero can produce deviant bookmarks resulting in more serious conditions or birth defects. Throughout our lives, a severe environmental insults can alter these bookmarks and produce an epigenetic disorder. Such insults can be psychological/emotional (inadequate or disrupted attachment, trauma, severe stress) or physical (exposures to toxic metals, radiation, chemicals). This field of research is called "Epigenetics" and it is revolutionizing our understanding of cancer, heart disease, developmental disorders such as autism and psychiatric disorders all which seem to be epigenetic in nature. With this comes good news - we have a degree of control over the expression or the turning on or off of our SNPs. Many disorders previously thought of as genetic and untreatable, are actually epigenetic and treatable using certain nutrients and/or lifestyle changes that powerfully affect gene expression. METHYLATION The most dominant factor in epigenetics is methylation. This is a biochemical process, which occurs a billion times every second, and involves the addition of a methyl group to an atom or a molecule. Meet methyl with it's carbon and three hydrogen atoms: 
I'm including a "simplified" diagram below, only to make two points about the process of methylation:
#1 - Its complicated #2 - There are a number of genes (in colored boxes) which collectively determine how much methyl someone has. Certain genes, including the infamous MTHFR, if expressed can result in undermethylation (not enough methyl), while others, such as CBS, if expressed can result in overmethylation (too much methyl). 
The most important methylation gene is MTHFR. While having a mutation at the C677T location can result in someone having undermethylation, this isn't always the case. It is possible (though less likely) to be homozygous (have both genetic mutations) for MTHFR C677T, and have normal methylation or even be overmethylated. The presence of the genes matter less than whether or not they are expressed. What matters most is the net sum of all of the expressed methylation genes.
Accurate diagnosis of someone’s methylation status is essential for treatment. A convenient and simple marker for methylation status is the whole blood histamine test. This is because methyl is the primary mechanism for breaking down histamine. If you have a low histamine level, your methyl is too high. If your histamine is high, your methyl is low. Aside from playing a role in whether or not our genetic mutations are expressed, methylation is essential for almost every system in our body, including:
METHYLATION IMBALANCES A database of 30,000 people by Dr. William Walsh, PhD (referred to by some as the father of methylation) found that 60-70% of people have normal methylation, 22% undermethylation (too little methyl) and 8% overmethylation (too much methyl). Abnormal methylation doesn’t translate to mental illness. Many highly successful CEO’s and athletes are undermethylated and many talented artists, writers and musicians are overmethylated. Of individuals with behavioral or mental disorders, however, 70% have a serious methylation imbalance. This is due to the impact of methylation on both genetic expression and on neurotransmitter activity. Nutrient therapies for methylation imbalances aim to normalize methylation, which normalizes neurotransmitter activity, which can alleviate symptoms. For example, methionine and SAMe are serotonin "reuptake inhibitors" and thus increase serotonin activity at the receptor site. Folate reduces synaptic activity of serotonin, dopamine and norepinephrine at the receptor site. For me, as a psychiatrist, this is incredible. For many struggling with brain related disorders, addressing methylation can mean never needing to start on medication. For others, treatment of a methylation imbalance can mean coming off or being on less or fewer medications. In some cases, such as when there is toxicity, such as mold toxicity, methylation treatment may not be tolerated until this is addressed first. What has been both fascinating and satisfying for those of us who have trained with Dr. Walsh, is being able to often predict someone’s methylation status even before seeing lab results. UNDERMETHYLATION: [Think low methyl, high folate , high histamine and low neurotransmitters (serotonin and dopamine) activity.] Symptoms & Traits:
The Incidence of Undermethylation:
Treatment: Nutrient therapies, which include methionine and/or SAMe, aim to increase methionine and increase serotonin activity. Because folate reduces neurotransmitter activity and these individuals are already low in neurotransmitter activity, folate should be avoided. In fact for better brain health, these individuals do better on a high protein diet (and thus high in methionine). They should avoid supplements that contain folic acid. ******Because multivitamins usually contain folic acid, they're problematic for many individuals with mental health symptoms. They contain copper and copper overload too, is very common in brain related disorders. OVERMETHYLATION: [Think high methyl, low folate and high neurotransmitter (serotonin, dopamine and norepinephrine) activity.] Symptoms and Traits:
The Incidence of Overmethylation:
Treatment: Nutrient therapies aim to increase folate and thus lower what is high neurotransmitter activity. Most important is folic acid, which reduces neurotransmitter activity. Niacin/niacin-amide also lowers dopamine activity. These individuals will do better with a high folate diet (veggies and fruit) as opposed to a high protein diet. THE FUTURE OF PSYCHIATRY Knowing that someone is depressed or psychotic or manic doesn’t tell you if they are undermethylated or overmethylated. It also doesn't tell you if they have copper overload, metal toxicity or pyrrole disorder - the other common biochemical imbalances. If everyone with depression took an antidepressant that raises serotonin activity, those with undermethylation would likely have significant benefit, however, those with overmethylated would likely get worse. Tragically for some, this can mean suicide or even homicide. Currently in conventional psychiatry, there's no specific way to know who those people are. Dr. Walsh's biochemical approach removes that guess work. His database and research informs physicians on how to evaluate and treat methylation disorders (and other nutrient imbalances) using targeted nutrient therapies. The fact that many conventionally trained psychiatrists are testing for MTHFR C677T and using the highly promoted methylfolate (Deplin) show that the psychiatric field is starting to grapple with these important concepts. However, adding Deplin to an antidepressant is missing the mark. Some may benefit; many will not and some will get worse. Again a mutation at the MTHFR gene doesn't tell you someone's methylation status. Also, if someone is undermethylated and depressed and likely low in serotonin, they can become more depressed if given more folate. To quote Dr. Walsh (from an interview on the ACN website) "... blindly using methylfolate (Deplin) for patients with C677T MTHFR or other weakened enzymes can produce negative results in patients afflicted by low serotonin activity. Folate supplements including Deplin tend to drive serotonin activity even lower.... The bottom line is that methylfolate and other folate supplements are very effective in enhancing methylation for autism and other conditions that are not dominated by low serotonin activity." (apathetic depression and anxiety typically involve low serotonin activity) *** Thank you for sticking with this lengthy post. My hope with some of these early articles (ie. on the microbiome, nutrient therapies and copper overload) is to provide resources and background for those wanting to better understand these complicated issues. Having done this, I look forward to more specific and shorter posts. If you'd like to go deeper into these topics, I recommend the following book and youtube videos: Nutrient Power: Heal Your Biochemistry and Heal Your Brian - book by William Walsh, PhD Undermethylation Myths, MTHFR & The Great Folate Debate - Holistic Psychiatry Newletter (2023) The Role of Methylation and Epigenetics in Brain Disorders - video presentation by William Walsh, PhD If you're looking for a physician trained in this area or are a physician interested in training, visit the Walsh Research Institute.

Thanks Courtney. I actually read your article. Based on what I think I understand, I may fall into the OVERMETHYLATION column. Fruits & veggies; not a strong part of my diet. Alot of protein is. Going to experiment and switch these things. Will let you know. 8/10/2015 07:48:26 am
Thanks Ronan - hope that's helpful. If you want to maximize the higher folate veggies, they would be things like spinach, asparagus, broccoli, brussel sprouts, okra, romaine lettuce. Higher folate fruits are strawberries, cantaloupe, banana and orange.

Wonderful article!! With regard to the high protein diet; Which proteins are most suitable and what percentage of the diet should comprise of these? Also, where does this leave us with regard to fats and carbohydrate? Many thanks! 8/12/2015 08:28:08 pm
Thanks Andrew. I don't have a percentage because like many things it can depend. Though I'm focusing on methylation here, the micro biome also matters a great deal and it seems to benefits from fiber - so vegetables and fruit remain important. Because methylation relates more to methyl (think protein) and folate (think veggies and fruit), fats and carbs don't factor in so directly. In general healthy fats seem to benefit brain health - ie. olive oil, coconut oil, butter and animal fat. Carbs ie. in the form of refined carbs (ie. sugar, white bread, pasta, etc.) are considered problematic. Some believe that all grains even whole grains are problematic for brain health, but I think this can depend on the individual. For most the best way to increase protein and/or veggies and fruit is to use them to replace some of the grains.

Dr. Synder--what few people realize is that the human microbiome is not just in the gut but occupies the entire body. We are a walking Petrie dish of bugs. Most of the diseases of aging are caused by stealth infections of L-form bacteria. 1/1/2017 11:50:27 am
why is the dimension of attention (or not) to detail, due to under or overmethylation - what neurotransmitter is involved for example? 5/12/2017 01:05:52 pm
Beverly. Apologies for my very delayed response. In under methylation, there is a decrease activity at the serotonin, dopamine and norepinephrine receptors. Low activity at the dopamine receptor would contribute to inattention. In over-methylation, there is an increase in the serotonin, dopamine and serotonin activity at the receptor site. If there is inattention here, it often relates to racing thoughts, high anxiety etc.

Hi I believe my schizophrenia is caused by overmethylation, I can't seem to find any journals about folate reducing neurotransmitter activity I'v only done a search with google so far, are those journals published and available on google? Alternatively is there some database of case studies i can read of people treated with folate for overmethylation? Kind Regards Frederick 5/12/2017 01:09:35 pm
Fredrick. If you haven't already checked these out, I would refer you to Dr. Walsh's book, Nutrient Power as well as the Walsh Research Institute link: http://www.walshinstitute.org/the-walsh-theory-of-schizophrenia.html.

Hi, my 3 year old suffers from a lot of anxiety, aggression, ODD-like behaviors at times. I was concerned about underlying causes and her MD ran some blood work. He only checked her B6 and B12 but they were both extremely high despite no multivitamin for a full week prior to the test and paleo diet with no fortified foods. I had read about MTHFR and thought she was maybe under-methylating and not able to use the vitamins correctly. However, her Red Blood Cell count, hemoglobin, hematocrit were all elevated as well. After reading about over-methylation on your site I'm wondering if she may actually be over methylating. Do you know if high RBC can indicate over-methylation since b12 is so key in making RBCs? Thank you for this post. 6/26/2017 04:40:48 pm
Hi Laurel. To my knowledge, there is not a relationship between a high RBC and overmethylation. When I do see abnormal blood cell indicators in people with brain related symptoms, I wonder about mast cell issues (you may want to look into Mast Cell Activation Syndrome and the work of Dr. Larry Afrin - he is a hematologist and really the pioneer in the area of mast cell activation). This can cause high levels of histamine (and other immune mediators) which can cause behavior and cognitive changes as well as physical symptoms. Often such individuals are very reactive to a range of things - ie. certain foods, chemical sensitivities, even bug bites, etc. It looks different in different people. Separately, there is some debate about the benefit of B6 and B12 levels and I'm not sure how much is known about levels in 3 year old. There are some who will argue that such elevations actually indicate an intracellular deficiency, rather than an excess. I don't regularly check levels for either of these, though I do use them in my nutrient protocols.
Hi, My daughter is 11 and has been having some PANDAS/PANs / tourettes like symptoms over the last year. She has been tested for the the MTHFR mutation and is positive for ONE copy of the C677T variant. Her symptoms are tics that change over time, throat clearing, nose sniffing, deep breath with shoulder shrug, occasional eye blinking, and some mild OCD tendencies. She has had tons of blood work done over the last year. No specific diagnosis has been made but a functional doctor is leaning towards PANDAS/PANS. Some of the irregularities that stand out: anti streptomycin O remains high after months, VEGF, elisa test is Low, anti nuclear AB titer high (although coming down), zinc was very low but has come up with supplementation, m. pneumoniae AB (IGM) remains high (but coming down). I (mom) am homozygous for MTHFR...but don't know the details because it was a test done long ago without anymore details. 7/6/2017 01:29:27 pm
Hi Pam. Not necessarily, but possibly. There are multiple genes involved in methylation. While MTHFR is seemingly the most significant, having a mutation doesn't equate to undermethylation, which is why we use a whole blood histamine or a methylation profile along with history of symptoms. Usually individuals are born with their methylation status, so longstanding traits or symptoms can be helpful in this regard. There are other things that can cause, for example, OCD tendencies, including PANDAS/PANS, but usually there is a more acute onset of symptoms. With PANS, I think about things like strep, m. pneumoniae, lyme, bartonella, candida and mold which is seemingly more common than previously realized.

So if I'm giving my child who is on the under end a multivitamin with methyl, then that's ok? 7/6/2017 01:37:59 pm
Hi Meaghan. I really can't say what's okay from this distant perspective and it does depend on the person's symptoms. In this blog post, I am focusing on brain related symptoms. There are for example individuals who are undermethylated and do not have low serotonin activity who do fine with methlyl folate, but we wouldn't recommend any form of folate to someone who is undermethylated and depressed. For someone who is depressed and undermethylated, other forms of methly (without folate)- things like methyl b12, methionine and SAMe work well. In what I do, I'm not usually recommending multivitamins, because they usually have folate/folic acid (and undermethlyation is common in brain related disorders) and because they often have copper (and again elevated copper is very common in brain related disorders).

Hi Dr. Snyder. Thank you so much for this information. I'm looking forward to reading your other posts to continue learning more. My daughter, age 5, is homozygous C677T, has been diagnosed with severe generalized anxiety as well as OCD(triggered be the trauma of me being in the hospital for a month last year) and has some attention difficulties. She is also extremely strong-willed and often has a calm demeanor but is internally tense and anxious almost constantly. Physiologically, she has moderate to severe eczema, a few food allergies and many environmental allergies. According to your information, it appears so is undermethylated, correct? My concern is I cannot find a doctor who is knowledgeable in MTHFR and knows how to help her. I'm not sure what my next step should be. Blood tests for histamine levels, heavy metals, vitamin levels etc and treat accordingly? Request further methyl genetic testing? Any advice on how to proceed is welcomed. Thank you! 3/5/2018 02:51:47 pm

This is very confusing to me because my daughter is homozygous for the c6777 mthfr gene she is also diagnosed with Adrenal fatigue, She was also diagnosed with general anxiety and depression.Her doctor prescribed very high doses of folate along with seeing a Psychologist who prescribed through her M.D. the drug Zoloft. 8/14/2017 08:45:45 am
Hi Elaine - I understand your confusion. It's more common that physicians are recommending folate for MTHFR, but as I indicated above, that is not the approach those of us trained by Dr. Walsh are using for individuals who have depression. Know also, there are other factors beyond methylation that can impact someone's ability to tolerate SSRI's - for example - mast cell activation. One of the challenges of writing this blog, is that it requires me to write about these topics as if they are separate entities. Most of the people that I see have a number of things going on simultaneously - not only methylation. I have some individuals that I see for example, who are under-methylated and have mold toxicity, and we can't start treatment approaches for methylation until we address the mold toxicity (they can't tolerate the treatment for methylation). Before you consider calling my office, you may want to see if there is a doctor closer to you who is trained in this area via the Walsh Research Institute research list. (http://www.walshinstitute.org/clinical-resources.html). If you are interested in more information about my evaluation and treatment process, feel free to call my office and Courtney (the adminstrative assistant) will be happy to give you that information. Best to you and your daughter.

Dr. Snyder, thank you for the information you share. Do you ever test for food/environmental allergies via scratch test, blood test, etc. if someone has high histamine levels? Does high histamine necessarily mean the person's behavioral and neurological symptoms are caused by methylation imbalance or could an allergic response causing inflammation be the cause? I'm wondering especially if this could happen even without typical symptoms of allergies like hives, mucous, etc. Would love to hear your thoughts. Thanks. 10/16/2017 12:50:59 pm
Hi Tom - Apologies for my very late response.

Thank you Dr. Snyder for the wonderful info. I recently had a genetic test stating I had a "A1298C" mutation. Majority of symptoms with overmethylation apply to me, but of course not all. I have starting supplementing with L-5-Methylfolate and my doctor prescribed viibryd as well due to my rejection history of SSRI's. I'm also supplementing with B complex, zinc, Vit. C, Vit. E, and Magnesium. My main question is I am already on 60mg Dextroamphetamine and 250mg of Nuvigil. I have and always have had a high drug tolerance with many different classes of medications. Seeing as Nuvigil works with our histamine to promote wakefullness, could this be causing overmethylation to stay the same or get worse? Nuvigil really does absolutely nothing for me. Dextro. works, but my tolerance has built up to it and it's not as effective. I seem to have a few "idiopathic" issues that this new genetic finding may hold a key to helping. My biggest medical issue is idiopathic hypersomnia w/long sleep. I'm 40 and it's been an issue all my life...and getting worse. If you're aware of Nuvigil being a better med. for undermethylation as opposed to over, I would greatly appreciate your feedback. I'm fortunate enough to have a dr. who was willing and able to help with the genetic tests, but as you stated it's still not all that well understood yet. I appreciate your time and effort in trying to help some of us understand this genetic mutation. Thank you, Kelly 10/16/2017 01:04:41 pm
Hi Kelly - It's hard for me to comment on your specific situation.

My 16-y-o daughter has struggled for years with depression, anxiety and BPD. the depression and anxiety have not responded well to a long series of SSRI drugs. (now using combination of prozac, wellbutrin and abilify). genetic test recently revealed heterozygous C677T in MTHFR gene. have spent a month slowly increasing folate as directed by doctor. up to 5 mg daily and just now added methylated B12. absolutely no improvement and possibly worse. have not had blood levels checked for histamines. is it possible this is the wrong treatment? might she benefit from methionine and SAMe? and how much of each is advisable? thank you. 10/16/2017 12:23:16 pm
Hi Martha - I really can't make recommendations regarding what your daughter should take or even what doses, as I have not evaluated her.

Thank you so much for this information. I have pyrrole disorder and I'm undermethlayted. Before I was feasted I had someone helping me that thought I was low histamine. She told me to take many supplements that had folate in it. When I finally got tested I had been on my period for 7 weeks. I quit taking everything at that time and now I've been on my period for 11 weeks. I'm exhausted and tired of trying to figure out the cause of this. Could it may be too much folate? 3/5/2018 02:57:30 pm
Christie - I hope you were able to find the help that you were seeking. Usually we associate copper with excessive menstrual bleeding. As it sounds like you are aware, for someone with undermethylation, we would recommend they be off folate and folic acid..if they have had symptoms of low serotonin - depression for example.

Hello! I just stumbled across this article in my search for a better understanding of methylation. My histamine level is 65 and my practioner thinks I'm over methylated. He started me on a hydroxy b12/folate combo and it knocked me flat. Thinking it was the hydroxy b12, he put me on methyl b12 by itself. I didn't react as severely yet overall, my symptoms of fatigue, depression, anxiety, trichotillomania, intolerance to foods and vitamins/minerals increased. My practioner wanted to add folate so I added 400 mcg to the methyl b12 and within 12-18 hours I experienced whole body inflammation aka weakness, fatigue, pain, puffiness. I'm beginning to think that I'm under methylated instead. Can you offer your opinion? :) Thank you! 3/5/2018 03:01:50 pm

I have MCAD/POTS/HEDS, homozygous C677T MTHFR, depression/anxiety. Whew! In addition to the Whole Blood Histamine test, what other labs (via standard labs covered by insurance) would you recommend to determine methylation and nutrient deficiencies? 7/18/2020 04:34:54 am
Hi Liz. This response is likely way too late to be helpful (I apologize, but still want to respond as other too may also have that question). I don't know of any other methylation tests that are covered by insurance. There are specialty labs that we use that measure various aspects of the methylations, but they are not covered by insurance. Thank you for your kind comment, I'm glad the information was or has been helpful to you. Best to you, Courtney

Hi! I am in the middle of a b12 deficiency horrible dizziness/pressure in back of head andleg weakness/tingling. The b12 makes me very anxious. The same thing happens when I take at Johns wort,Zoloft, compazine and reglan. I suspect I overmethylate. However my copper serum level was 254 and then went down to 178 (still high). So I’m not sure what to treat or what to do. The dizziness is horrible I went from fully functioning very active to doing NOTHING. 8/9/2020 08:15:31 am
Hi Colleen. If you haven't, you may want to read my last post about mast cell activation. Though my own functional medicine training started out very much focused on the Walsh nutrient levels, I have found that for a number of people, there are deeper roots to their nutrient imbalances beyond genetics. Mold toxicity for example seems to worsen copper overload. It also causes mast cell activation which makes people often highly reactive to various medications, supplements, sometimes certain foods, etc. I have another post on that as well. I wouldn't consider dizziness a symptom of high copper or a methylation imbalance, but it could be related to mast cell activation and/or mold toxicity.

Hey, so I recently gave birth to my second child 3 months ago. Since giving birth ive had high hemoglobin & hematocrit, high b12 & folate, & POTS like symptoms, minus the drop in blood pressure but everything else fits to a t. My anxiety has been thru the roof since getting pregnant. My hematologist has no idea what’s causing the high hemoglobin, my jak2 was negative. Wondering if it could do with mthfr mutation, & how do I go about getting tested? Do I test for overmethylation? Also what can I do to stop feeling like I’m dying constantly. Do I change my diet & take supplements? I’ve been told a low histamine diet but I fear that’ll affect my milk production too much. 11/27/2020 05:14:54 am

Thank you for an excellent article!! I have read hundreds of books and studies on mental illness. Your explanation of methylation is outstanding! Now I get it!! Thank you. 1/10/2021 01:22:01 pm
Hi Terri. Thank you. I'm glad it was helpful. I would defer to Dr. Mensah, as he has more information and knows your son. Generally we try to avoid Omega 3's (fish oil is rich in omega 3's) when someone has especially high pyrroles (in the high twenties or above), and instead use Omega 6's usually in the form of Evening Primrose Oil. I do feel MTC can be beneficial for brain functioning for a number of reasons, but again I'm not in a position to know what would be best for you son. Thank you again for commenting.

Thank you very much for the response Courtney! I do not think I have mast cell activation and I do not think for me yeast was the cause, however pyrrole disorder seems to fit my symptoms. I had a blood test done to test my homocysteine levels and they were normal, although I did a promethease gene report and it said I was at risk for high levels (homozygous for C677T of MTHFR = 10-20% efficiency in processing folic acid). I know that pyrrole disorder can be tested for via urine, but is there any way I can see if I have it myself? I have had blood work done in the past, and I read that for this disorder it is common to have low levels of magnesium, zinc, and vitamin B6. I tested low for all of those. My copper was slightly higher than my zinc, but still low. When I say low, they were in the green (normal) but close to the yellow mark, which is not normal. 8/19/2021 05:02:21 pm

I found this incredibly interesting. I was wondering, is it possible for an individual who is in a cycle of overmethylation to have an intolerance to protein? I find that my anxiety skyrockets shortly after a high protein meal. I have some food sensitivities and never understood why this would be the case as meat has gotten a green light on every gut diet I've ever tried. I was also wondering how hormones might impact this cascade. I have very low free testosterone, but when I try to supplement I have the same reaction as to meat. Have you happened to study how hormones might impact methylation (if they do at all)? Thank you for an excellent and informative read.
Courtney B Snyder
7/30/2021 01:42:26 pm
Hi Shanna. Thank you for your lovely comments. Depending on one's overall seeming methylation status, a reaction to protein could be due to other factors, such as histamine in the protein source (certain proteins fall into the high histamine food category) and/or problems with breaking down protein and even a sulfate metabolism issue (usually the later is felt the next day). Also too much protein in someone with yeast can create acidity which can increase yeast. Any of those could trigger inflammation which can cause brain related symptoms. I don't know of a direct relationship between testosterone and methylation, however, it's possible that there is something in your supplement that is triggering inflammation. I'd be curious what is in that supplement. Thank you again, Courtney
Shanna
7/30/2021 02:05:29 pm
Interesting that meat can increase yeast. This is counter-intuitive so I'm grateful to have it pointed so. I would have thought that yeast would increase more with foods that get easily broken down into sugar and that acidity would help (maybe thinking of vaginal yeast and how a low pH is typically helpful). Regarding your curiosity on the testosterone supplement, I've tried 3 different types. Custom compounded cream (I now have just Estrogens in the cream and don't have a problem), pellets (awful), and Axiron in a teeny tiny dose. They all do the same thing so I don't think it has anything to do with something inactive in the supplement. I had always heard that Testosterone is supposed to help with sleep and mood, but no matter how little I use I always feel worse. I know that testosterone increases tryptophan in the body which is a serotonin precursor. I have learned that meat does this as well and was wondering if the two are triggering the same mechanism. It's all very complex and difficult to solve. I imagine there are a bunch of people walking around with mental health disorders who actually are having issues physiologically instead of psychologically. Thank you very much for your response!

Hi Courtney, I just discovered you and your site and am loving your articles and videos. Thank you! My 13 year old and I both have pyroluria and under methylation. We were tested 2 years ago and have been on a protocol by Dr. Mensah. I am having him retested right now, he is really struggling, I think it is from both puberty and a growth spurt. You mentioned things affecting methylation in utero. When I was pregnant with him, long before knowing anything about pyroluria or methylation, I had been taking Rainbow Light prenatal vitamins. At the time they had one that required taking 6 per dose and another one that was one per dose. I had been taking the one with 6 per dose and then when I bought the next ones I bought the 1 per dose one without realizing. I took 6 for probably a week or two before realizing and then panicked that I was overdosing my baby on vitamins. My dr said not to worry. Looking back I’m thinking it must have affected his development, that much folate. What do you think? How would it have affected his mental development?

There are a lot of MTHFR tests on the market. Do you find that some are better than others? Do you have any particular labs you trust for MTHFR testing? Thanks so much. Love your blog.

Hi Courtney, I just wanted to say that I found this article fascinating and yet confusing at the same time in my situation. I have had my histamine levels measured by dried blood method and they are low. I believe that I would fall into the overmethylated catergory. I have sone of the overmethylated personality traits and have had adverse reactions to both Same and methionine supplements but I have struggled with depression and anxiety and have benefited greatly from Effexor. I am also bipolar with ADHD and this information seems contradictory in my case. Do you have any thoughts on this? Thank you so much in advance.

Thank you very much for this valuable information about undermethylation. How might one know whether to supplement with SAMe versus l-methionine? Just trial and error? On Doctors Data methylation profile, methionine was in the 50th percentile and SAM was in the 2nd percentile. Your comment will be posted after it is approved.
