I am so happy to report that the MTHFR C677T mutation now comes with a superpower, and it’s prostate cancer protection.  It’s not quite X-Men worthy and I have to admit mind control might be a bit cooler, but protection against one of the most common forms of cancer is nothing to scoff at.

The association between MTHFR mutation and prostate cancer has been unclear, with some studies showing increased risk, some studies showing no change and some showing decreased risk, so the information can be difficult to wade through. A recent research study conducted in Shanghai and published in Scientific Reports shows that C677T polymorphisms, whether they are homozygous or heterozygous, are actually protective against prostate cancer although they are quick to say that this study was conducted on the Han Chinese population in Shanghai and that the results may be different for different ethnic groups.

The study shows that intracellular homocysteine levels are slightly elevated when the C677T mutation is present and that elevated homocysteine actually helps to encourage damaged cells, such as precancerous and cancerous cells, to die off the way they should, rather than proliferating into full blown cancer. In unfortunate news, a recent meta-analysis published in Genetics and Molecular Research, showed that this association may not exist in caucasian males and that in this population C677T mutation may not have any effect on prostate cancer. Interestingly, this same meta-analysis showed that the A1298C mutation might have a slight protective effect against prostate cancer in European males.




The most important thing to remember, is that almost every mutation that exists in humans or animals has a double edge – it often has some drawbacks, but typically benefits too or the members of the population with that mutation would die out.  MTHFR seems to be, if anything, becoming more common so I suspect in years to come we will find many other benefits associated with it.



Am I Overmethylated? MTHFR Questions.

Overmethylated vs. undermethylated seems to be one of those things that everyone defines a different way, so let’s talk about it and see if we can bring some clarity. The terms overmethylation and undermethylation make the most sense to me as the Walsh Research Institute uses them.  These are general physical tendencies based on the sum of your genetics, nutritional status and body burden. There isn’t one gene or genetic defect alone that can account for them – so just because you have an MTHFR C677T mutation doesn’t actually mean you’re over or under methylated (although it would be one factor that might push the balance to undermethylation).  Dr. Walsh describes one’s methylation status as being like a tug of war between opposing factors. Many of those are genetic and some are nutritional or environmental.

Overmethylation MTHFR

This is less common than undermethylation. According to Dr. Walsh’s research, 70% of the population are normal methylators, 22% are undermethylators and 8% are overmethylators. Overmethylation in this context means that the methylation cycle as a whole is sped up, or downstream reactions that use SAMe (the ultimate product of the methylation cycle) are compromised in such a way that there is too much SAMe floating around wanting to methylate something.

  • Clinically overmethylators are more likely to have agitated or anxious conditions. Frequently panic or anxiety attacks (64% of panic/anxiety clients at the Walsh Research Institute), paranoid schizophrenia (52% of paranoid schizophrenic clients at WRI were overmethylators), ADHD (28%), behaviour disorders (23%), depression (18%). Depression  can occur in under, normal or over methylators but 18% of depressed clients of Dr. Walsh are overmethylators.
  • Mutations most likely to contribute to overmethylation are AGAT, GAMT, CBS and MT. MTHFR mutation usually pushes towards undermethylation (but I myself am compound heterozygous MTHFR and an overmethylator) Remember that the presence of one or more of these mutations isn’t enough to say if you’re an over or under methylator. The combination of all of your genetic factors as well as your nutritional state must be taken into account. The best way to determine is through symptoms and traits.
  • Other contributing factors are impaired creatine synthesis. This is because Approximately 70% of the SAMe from the methylation cycle is used by creatine synthesis, so if this is impaired the SAMe is used more slowly. This can be due to genetic factors (AGAT or GAMP) or due to deficiencies of arginine or glycine. Also impaired cystathione synthesis, or other polymorphisms in methyltransferase SNPs that account for the rest of the SAMe use.
  • Overmethylation leads to excessively high activity of dopamine, norepinephrine and epinephrine in the brain.

    If this reminds you of you, you could be overmethylated. A photograph of Robin Williams taken by Michael Dressler in 1979, later used as a cover photo for Time magazine to highlight Williams.

  • Symptoms and traits of overmethylation include:
    • High anxiety
    • Sleep disorder
    • High energy, restless, must move and fidget
    • Verbose or talkative
    • Often high artistic or musical ability
    • Antihistamine intolerance (makes anxiety or restlessness worse)
    • Overly empathetic with others
    • Non-competitive in sports
    • Tendency towards food and chemical sensitivities
    • Less likely to have seasonal allergies
    • Histamine Intolerance (or HIT – this is essentially a food sensitivity to high-histamine foods)
    • Low libido
    • Dry eyes and mouth
    • Adverse reaction to SSRI drugs, SAMe or methionine (typically all make anxiety or depression much much worse.
    • An easy way to picture this type is by using Robin Williams as an example.

Is Overmethylated the Same as Over-supplemented?

No, although it seems that in a lot of popular literature on the subject people use the term interchangeably. So often you’ll see someone say that you might  be “overmethylated” if you are taking too much 5-MTHF or SAMe.  I feel that these are different things entirely.  If you have a tendency to be overmethylated then certainly you would probably feel worse taking something like SAMe, but even without that you are still an overmethylator (in my opinion).  Likewise taking too much 5-MTHF, doesn’t make you suddenly “overmethylated” it just means you’re taking too much.

Okay! I’m Overmethylated. Now What?

Interestingly the best way to balance the consequence of overmethylation, is still 5-MTHF.  This seems strange, because it is also the answer if you’re’ undermethylated, but the effects are actually coming from a different mechanism. Folate actually reduces activity at serotonin, dopamine and norepinephrine synapses. 5-MTHF is the active form of folic acid, and you can also get it from foods, especially if you have some trouble taking the supplement.  Trouble taking the supplement is surprisingly common, although I think less common clinically in overmethylators (in my experience) than in undermethylators. Niacin or niacinamide can also be helpful for overmethylators as they quench some of the excessive methylation. Again, start slowly.

I Want to Start Taking 5-MTHF. How Do I Make This Easy?

Any time you start taking 5-MTHF, or increase your dose, there will be an adjustment period.  Here’s a whole post on it.  Just remember, start with a low dose and increase really slowly. This is changing the way your neurotransmitters work and doing some heavy detox work, so it’s vital not to overdo it because that is crazy-making. Start low and go slow.



If This Sounds Like You, You Might be Undermethylated

MTHFR mutation discussions can quickly turn into Greek and the topic of overmethylated vs undermethylated MTHFR is one of the Greekest. It seems like no two resources on the internet are talking about the same thing when they talk about it and so overmethylation and undermethylation are strange, kind of meaningless words because at the end of the day it feels like nailing jello to a wall. So let’s see if we can sort some of this out.

Whose Idea Is This? I’m Following The Walsh Research Institute

The terms overmethylation and undermethylation make the most sense to me as the Walsh Research Institute uses them.  These are general physical tendencies based on the sum of your genetics, nutritional status and body burden. There isn’t one gene or genetic defect alone that can account for them – so just because you have an MTHFR C677T mutation doesn’t actually mean you’re over or under methylated (although it would be one factor that might push the balance to undermethylation).  Dr. Walsh describes one’s methylation status as being like a tug of war between opposing factors. Many of those are genetic and some are nutritional or environmental.

Undermethylation MTHFR

This is the most common state. According to Dr. Walsh’s research, 70% of the population are normal methylators, 22% are undermethylators and 8% are overmethylators. Undermethylation indicates that the methylation cycle as a whole is slowed down enough that the end product, SAMe, is typically inadequate and thus causes symptoms.

  • Clinically undermethylators are more commonly autism spectrum (98% of autism spectrum clients at the Walsh Research Institute), antisocial disorder (95% of antisocial clients at WRI were undermethylators), schizoaffective disorder (90%), oppositional defiant disorder (85%), anorexia (82%), and depression (which can occur in under, normal or over methylators but 38% of depressed clients for Dr. Walsh are undermethylators).
  • Mutations most likely to contribute to undermethylation are MTHFR (C677T especially, but also A1298C), MS, BHMT, MAT and SAHH. Remember that the presence of one or more of these mutations isn’t enough to say if you’re an over or under methylator. The combination of all of your genetic factors as well as your nutritional state must be taken into account. The best way to determine is through symptoms and traits.
  • Other contributing factors are histamine overload and protein deficiency, as well as frank deficiency of folate.
Highly competitive? You might be undermethylated

Highly competitive? You might be undermethylated




  • Symptoms and traits of undermethylation include:
    • Strong willed
    • Highly competitive at sports or whatever matters to them
    • Obsessive/compulsive tendencies
    • Addictive tendencies (more likely to be addicted with less exposure than a normal methylator)
    • High sex drive
    • Tend towards high accomplishment and usually a high achieving family
    • Appear calm and well controlled (possibly over-controlled) but inner tension is high
    • Greater likelihood of seasonal allergies
    • Higher fluidity of tears, saliva, etc…
    • Perfectionist
    • Less likely to be compliant with therapies

Is Undermethylated the Same as Under-supplemented?

No! Although it seems that in a lot of popular literature on the subject people use the term interchangeably. So often you’ll see someone say that you might still be “undermethylated” if you aren’t taking enough 5-MTHF.  I feel that these are different things entirely.  If you have a tendency to be undermethylated then certainly you will probably need to take 5-MTHF, but even once you’re taking enough you are still an undermethylator (in my opinion), you’re just taking the right protocol.  Likewise taking too much 5-MTHF, doesn’t make you suddenly “overmethylated” it just means you’re taking too much.

Okay! I’m Undermethylated. Now What?

Absolutely the best way to enhance the methylation cycle is by taking 5-MTHF, or 5-L methyltetrahydrofolate.  This is the active form of folic acid, and you can also get it from foods, especially if you have some trouble taking the supplement.  Trouble taking the supplement is surprisingly common, typically it is an adjustment reaction to actually enhancing the methylation cycle because this changes neurotransmitter levels, encourages detoxification and encourages more than 80 reactions in the body that are methylation dependent. So some adjustment reaction when you’re first taking 5-MTHF is normal and actually a good sign that things are changing in your body.   There is one BIG EXCEPTION TO THIS, and that is if you are undermethylated and have depression.

I Want to Start Taking 5-MTHF. How Do I Make This Easy?

Any time you start taking 5-MTHF, or increase your dose, there will be an adjustment period.  Here’s a whole post on it.  Just remember, start with a low dose and increase really slowly. This is changing the way your neurotransmitters work and doing some heavy detox work, so it’s vital not to overdo it because that is crazy-making. Start low and go slow.

HELP! I’m An Undermethylator and I Have Depression.

My next post is going to be all about this because UNDERMETHYLATORS WITH DEPRESSION DUE TO LOW SEROTONIN CAN’T TOLERATE 5-MTHF, FOOD SOURCES OF FOLATE OR FOLIC ACID AT ALL. That’s a really big deal! Depression is typically characterized by low serotonin states and unfortunately 5-MTHF (or any folate or folic acid). The short explanation for this is that folate, 5-MTHF and folic acid all increase the activity of the transport protein that re-uptakes serotonin into the cell. Essentially this is the opposite of a serotonin reuptake inhibitor (like prozac), it’s a serotonin reuptake promotor – meaning it makes the serotonin you have far less effective because it clears it out more quickly. There will be a whole post on this – I promise!

I Have MTHFR A1298C Mutation – What Does That Really Mean?

MTHFR mutations are just starting to be recognized as an issue and so more and more doctors are testing, but what happens if your doctor tells you that you’re homozygous for MTHFR A1298C? They might as well be speaking Greek! So here’s the skinny on what that really means. Also here’s a post about MTHFR mutation basic in general.

MTHFR A1298C Terminology Basics (or as basic as we’re going to get with genetics).

The simplest level of information here is just the plain genetics.  Here are some quick factoids to get us started:

  • MTHFR is the short name for the genes that code for the enzyme that changes folic acid to the active form that your body uses (the long name is methylfolate reductace).
  • 1298 is the marker for one particular MTHFR gene.
  • The official genetics labeling of this gene is Rs1801131. Sigh.
  • You get one copy of this gene from your mother and one from your father, so there are two possible copies that can be either “normal” or “mutant”
  • If you inherited one good copy and one bad copy that’s called “heterozygous A1298C”
  • If you inherited two bad copies (one from each parent) that’s called “homozygous A1298C”
  • A…C stand for the bases that you actually have.  A = adenine C = cytosine.  Bases are essentially the letters that spell out your genetic code.  There are four of them commonly (C, T, A and G).
  • When this gene is “normal”or “wild type” (I love that name) it looks like MTHFR A1298A.
  • Heterozygous mutations (one good copy and one bad) are MTHFR A1298C because there is one normal A and one abnormal C Also occasionally written 1298AC.
  • Homozygous A1298C (two bad copies) can also be written as C1298C (because there are two abnormal copies with C instead of A). Occasionally you’ll also see it written 1298CC

Phew! So the take-away there is MTHFR A1298C means you have at least one bad copy of this gene, and if it’s called homozygous, or C1298C then you have two bad copies.

How Much of a Problem Is This?

The MTHFR A1298C mutation is considered less serious than the C677T mutation because it seems to cause less impairment to actual methylation function than C677T.  That doesn’t in any way mean that it isn’t an issue. This mutation can still be a significant problem If you don’t have a good diet, don’t take supplements or burden your body with a lot of stressors like smoking, alcohol, drugs, sedentary lifestyle or high stress. If you get lots of dark green leafy veggies, legumes and other food sources of natural folate – see this post – then you’re probably already getting good methylfolate. If your diet isn’t up to scratch, then supplementation can be useful and here’s a whole post about that.

Heterozygous MTHFR A1298C is thought to have mostly normal MTHFR activity  and homozygous MTHFR A1298C (C1298C) have about 65% normal activity (so 35% compromise). Normal activity refers to the way your body converts folic acid to 5-L-methyltetrahydrafolate (the active form) so that it can be used. Compromise in this case looks like a folate deficiency.

What Are The Health Risks of MTHFR A1298C Mutation?

According to SNPedia, which compiles research on genetics, A1298C mutants have been shown in at least one research study to have an increased risk for:

  • Midline defects such as:
    • Cleft lip
    • Cleft palate
    • Neural tube defects
    • Facial asymmetries
  • Cancers including:
    • Breast
    • Lung
    • Brain
    • Stomach
    • Head and neck
    • Kidney
  • Cardiac-related issues including:
    • Thrombosis (increased tendency to clot inappropriately)
    • High homocysteine levels (a heart risk)
    • Pre-eclampsia (dangerous high blood pressure in pregnancy)
    • Vascular dementia
  • Fertility issues including:
    • Multiple pregnancy loss
    • Low sperm count
    • Birth defects such as down syndrome
  • Neurological issues including:
    • Migraines
    • Autism
    • Alzheimer’s dementia
  • Mood and psychological issues including:
    • Depression
    • Anxiety
    • Schizophrenia

You’ll notice that this is quite a list, and it can be a little daunting to think about when you’re just learning about this. Most research doesn’t differentiate between the A1298C genetic variance and the C677T genetic variance so the list is the same for both mutations.  We assume the risk is lower with A1298C because the folate metabolism is less strongly impaired, but that might not be correct.

What Do You Do About This?

Compromise with the MTHFR A1298C gene can have severe consequences so it’s important to work on getting good sources of natural folate from foods, which is generally useable by mutants, or 5-MTHF (5-methyltetrahydrofolate) which is already methylated so the genetic compromise doesn’t matter.  As discussed in this article, I feel supplementation should be started slowly because for many mutants who haven’t had active folate very much in their lives it feels really strange when those active forms start showing up.  There can be quite an adjustment reaction  by your body.

Activated folate is used by your body to run enzyme pathways, to aid in some parts of normal metabolism, to help your body detoxify and even to methylate your DNA. The methylation cycle is also a big part of neurotransmitter manufacture, which explains the strong link to depression, anxiety, and mental disorders including addictions and even schizophrenia. If 5-Methylfolate  isn’t there then your body does maintains those functions as best it can, but the things your body can’t do start to pile up. Starting supplementation means your body can start digging in that pile to clear up high priority items.  This is exactly what we want, but if you start with high doses of a supplement then it’s a little like drinking from the firehose.  Kind of out of control and not very pleasant.

A great way to start if you’re unsure, is with a folate-rich diet.  I love this image because it kind of covers what we’re looking for.  Hint – think dark greens and beans. 🙂

Can Mutants Become “Normal”?

If you’re a mutant (like me) then you’ll always be a mutant, but it doesn’t have to matter. Essentially as long as you’re getting enough of the active form of folate and taking care of yourself for the other consequences of the MTHFR mutation then the mutation doesn’t have to matter.  If you aren’t taking care of yourself, then it matters a lot.

The bottom line is MTHFR A1298C mutations don’t have to mean anything at all as long as you supplement and have a good diet and lifestyle (here’s an article about a folate-rich diet for MTHFR mutants) I always suggest taking a little more care with yourself too.  There are known health risks for things like clotting, fertility and cancers so it makes sense to take some precautions.  Eat your fiber, do your exercises, get your sleep and generally treat yourself with high regard – shouldn’t we all anyway?

Phew! So the take-away there is MTHFR C677T means you have at least one bad copy of this gene, and if it’s called homozygous, or T677T then you have two bad copies.

If your diet isn’t up to scratch, then supplementation can be useful and here’s a whole post about that.

Heterozygous MTHFR C677T have about 65% normal MTHFR activity (so 35% compromise) and homozygous MTHFR C677T (T677T) have about 30% normal activity (so 70% compromise). Normal activity refers to the way your body activates your folic acid so that it can be used, so compromise usually looks like a functional folate deficiency.

What Are The Health Risks of C677T Mutation?

According to SNPedia, which compiles research on genetics, C677T mutants have been shown in at least one research study to have an increased risk for:

  • Midline defects such as:

Is Genetic Testing Necessary if You Suspect MTHFR Mutation?

The quick answer is no. You probably don’t need genetic testing for MTHFR even if you suspect there’s a problem, but you still might want it.  If that isn’t enough information, then read on!

Why Genetic Testing for  MTHFR Might Not Be Necessary

  1. For many people with the MTHFR mutation, there is a simpler, more medically recognized, cheaper test called homocysteine.  For the majority of MTHFR folk homocysteine levels become elevated because of the lack of usable folate. This test is cheap and you won’t have any trouble talking your doctor into ordering it.  Bonus!
  2. Dr. Charis Eng, a prominent geneticist at the Cleveland Clinic makes a great argument that really, if you suspect a mutation, you can just take the methyl-folate and appropriate B vitamins and you’re done.  No harm, no foul. In short you don’t need genetic testing because you can just go ahead and take the vitamins. Good point Dr. Eng!
  3. Even with a complete genetic profile run through every methylation panel out there, finding the right dose of methylfolate for you is still a lot of educated guessing and trial and error. Testing might give you guidelines, but you really still have to start slowly and work your way up.

Are There Reasons Why I Should Do Genetic Testing for MTHFR?

There are certainly some compelling reasons to get the testing done, not the least of which is your kiddos.

  1. With genetic testing, especially the complete information gathered from 23andme, you have a better idea of not only your MTHFR status but also about all of the other genes that play into the methylation and detoxification process.  It helps us understand all of the ways you might be compromised and so gives a more solid starting place. (If your doctor runs the MTHFR test then really you’ll only have info about MTHFR, not about any of the related genes).
  2.  You know right away how compromised you are (check out these handy graphics if you can’t remember) and generally the more bad copies of the genes you have the slower you want to go with supplements and detox.
  3. If you have kids or are thinking about having kids it really helps to know what their chances are of picking up bad copies of these genes from you.   If you know there might be an issue then you can start helping them find balance while they’re young (or even before they’re born).

What are the Options for Genetic Testing for MTHFR from my MD?

MDs have started ordering testing – especially if you have some strange blood coagulation issues, if you’ve had repeat miscarriages, or if you pester the hell out of them. Insurance will only cover testing if it’s “medically necessary” – and typically that is only if there are weird blood clotting issues. Just keep that in mind. There are only a few MTHFR tests that are FDA approved, and none of them are intended for people with anxiety, depression, inflammatory disorders, etc… They still work, but it can be hard to talk your doctor into ordering them. These are all spendy if insurance isn’t paying for them, so ask your doctor before you have them run.

Is there Genetic Testing for MTHFR that You Can Run Yourself?

This is by far my favorite option, simply because you get so much for so little money (relatively speaking).  It’s 23andme. They provide you with a saliva test kit that you mail in and in about a month you get a whole heap of information online including info about your ancestry, about your genetic response to certain pharmaceutical drugs, and about different health risk factors. At the time of this article it’s $199 US or $249 Canadian. Typically this is cheaper than the FDA approved testing and there’s far more information. Embedded in all of this information is your MTHFR status, although it’s hard to find unless you run your results through some kind of interpretation engine.

In terms of interpretation for MTHFR there are a couple that I like.  The one I suggest most often is called “genetic genie” and they have a methylation panel (that uses the raw data from 23andme) and a detox panel (again with the 23andme). The reports are very complete and they ask for a modest donation.  Freaking awesome.

Another good option are the reports from MTHFR support.  This report shows more gene snips than the genetic genie report, but gives less information about each one.  It also costs a little more (but still totally reasonable).  Like genetic genie, MTHFR support doesn’t actually test the genetics – you need 23andme for that – they just interpret the information.

At the end of the day you can get genetic testing for MTHFR if you choose, but you don’t really have to – you can also just go ahead and start to supplement if you suspect an issue. I’m a total geek for information, so of course I got mine done by 23andme (I’m 3% neanderthal, in case you were wondering, because obviously that is information everybody needs).  I’m glad I know, but honestly it really didn’t change too much about the way I approach my dosage of methylfolate.  It’s just better information for me (and for my kiddos).
