Folic Acid – Why You Should Avoid it With an MTHFR Mutation

*Consult your doctor before making any changes in your dietary intake related to folic acid. This article is for informational purposes only and not a substitute for medical advice.

Nowadays, many people have issues such as fatigue, irritability, brain fog, anxiety, insomnia and other aches and pains without an apparent cause. Some might think that genetic disorders are the obvious cause. There are many minor genetic differences that influence the way we look and can cause many health problems.

MTHFR stands for methylenetetrahydrofolate reductase. MTHFR is the enzyme that activates folic acid by adding a methyl group to it. MTHFR physicians say that if you have an MTHFR gene mutation then you should stop consuming folic acid and replace it with its active form, Methylfolate. Our bodies can’t process excess folic-acid and it is stored as toxins in our organs and tissues. MTHFR practitioners say that the human body needs to convert folic acid into a form of folate that the body can use. The human body, without the MTHFR enzyme, can’t convert folic acid into methylfolate and it builds up in the body as endogenous toxins. As a part of MTHFR gene mutation treatment, you should avoid consuming folic acid or the products that contain it and replace it with methylfolate. Do so only under the guidance of an MTHFR physician.

MTHFR doctors warn people with low activity of MTHFR enzyme that may it cause elevated homocysteine levels. Homocysteine is an amino acid that could be inflammatory. Homocysteine is directly related to cardiovascular disease.

Treatment for MTHFR includes avoiding sources of non-metabolized folic acid which may cause other health problems that might not develop for years. Replace folic acid with methylfolate. An increase in the level of folic acid may also decrease natural killer cell cytotoxicity and weaken the body from fighting arthritis, cancer and anti-malarial drugs.

In older people who have B12 deficiencies, folic acid can cause cognitive impairment and anemia but methylfolate will not. Folic acid has the capacity to fight against many cancers but it can also accelerate the growth of tumors that are already present in the body that is suffering from MTHFR deficiency. The degree to which the body doesn’t activate folic acid to methylfolate increases your susceptibility to allergic responses and can also cause blood clots, strokes, anxiety, depression, high blood pressure, migraines and more.

Many thyroid issues have been associated with having an MTHFR mutation problem as thyroid hormones must be activated within the nucleous of each cell and it depends on methylation for this activiation. As part of a treatment for MTHFR gene mutation, women with a positive MTHFR status should consult an MTHFR doctor during pregnancy. MTHFR practitioners and also encourage pregnant women to check their MTHFR mutations and suggest that they consume appropriate levels of methylfolate instead of folic acid.

Without knowing the genetics and exposure to toxins, it is better to follow the advice of MTHFR physicians and start the intake of activated folate instead of folic-acid. As a part of treatment for MTHFR, you should consume plenty of organic green leafy vegetables as they contain good quantity of folates. Eat more broccoli and spinach, and always shop organic. MTHFR gene mutation treatment also includes checking B complex and multi-vitamins to make sure the label says methylfolate and not folic acid.

For the naysayers who think this is all rubbish look at the prescribed drug for folic acid deficiency, Deplin’s active ingredient is L-Methylfolate and not folic-acid. The scientists know this is true so when supplement companies use folic acid it is because it is cheaper, not better.

MTHFR gene mutation treatment can help those with MTHFR mutation to reduce their risk of health problems. Find out if you have a mutation by ordering a home test kit now.

    I suffer from psoriatic arthritis and Iam on methotrexate once a week I have been advised too take folic acid , would you advice not taking the folic acid ?

      Dear Elaine and Linda,

      For the most part it is better to take Methylfolate rather than folic acid, however what we recommend is for you to consult with a practitioner that is experienced in the subject to evaluate your condition and determine what you should be taking and how much. Please check our directory at https://www.mthfrdoctors.com/system/

        I’ve just finished 5 months of MTX chemotherapy for Choriocarcinoma, I was given Folinic Acid as a recovery and told that folic acid doesn’t help…confusing when so many are told to take it when they are on a low weekly dose of MTX for AI diseases ?

        I was on Methotrexate and the Folic Acid. I developed Felty’s Syndrome and lost my immunity. I do not know if it had anything to do with th MTFHR as I was diagnosed with it until last year, six years after developing the Felty’s. I am Homozygous for MTFHR. I am now on Deplin.

          Deplin is definitely a better choice than folic acid, however Deplin comes in 5mg to 15mg which when taken long term could through your body into over-methylation. You should check your serum folate levels and consult with a physician that specializes in MTHFR to help you get on the right dosage long term.

      My daughter and grandson were tested and have MTHFR and assume I do too. I am deficient in pantothenic acid and borderline in B12 and Folate. I am about to take hydroxycobalamin B12, but with it would you recommend methylfolate or can folinic acid be taken instead? I am concerned about taking anything that could cause palpitations or anxiety. Thank you.

        You can definitely try folinic acid. If you don’t feel good just stop. Folinic acid acts more on building DNA while methylfolate on methylation.

    I have gotten blood clots and they have done thorough blood tests and told me to take Folic acid 1000 mil and B-100 complex vitamins because my hymoglisteen was high an I have lupus anticoagulants at 112. Should I be taking these ?? I have 4 blood clots in my right leg 2 in my main artery

    Dear Joyce,

    We cannot give you medical advice in here, however you should get tested for MTHFR to determine if your body can metabolize Folic Acid. You should also consult with one of the doctors in our directory to get coaching on exactly how much to take and what else you might need.

    1. Support Team

      Not necessarily. There are other factors that affect homocysteine levels. For example; you may also have a mutation on a CBS gene that is an up regulator that will counter the MTHFR mutation bringing homocysteine levels down. In this case despite your homocysteine levels being down other aspects of the methylation cycle may not be optimal so homocysteine is only one marker to look out for. There are also other epigenetic factors that will affect homocysteine levels.
      If you have a mutation on MTHFR you must always look at your folate levels. Please read the following article:

      We also advise you to get guidance from one of the healthcare practitioners listed in our directory to make sure you get the right advice.

    I was taking folic acid for 6 months before getting pregnant then switched to pregnacare once I was pregnant. At my 12 week scan last week we found no fetal heart beat and baby had stopped growing at 8+4. We are obviously devastated and looking for answers we probably won’t ever find. I have hypothyroidism and take 100mg levothyroxine daily. Is this potentially an indicator of MTHFR? Or does it not work like that?

    1. Support Team

      We are sorry to hear about your loss.
      Pregnacare has folic acid and not methylfolate. Although there have been studies showing a connection between hypothyroidism and MTHFR mutations, being hypothyroid does not automatically guarantees you have a mutation. The first step is to get tested. We recommend either ancestry.com or 23andme.com. Once you have their results you may come back to this site and select the Methylation report under DNA Reports.

    While pregnant with my son they found spina bifida at the 20 week checkup and found mtfhr after testing me. They told me that it was because of needing more folic acid and baby aspirin. He gave me a prescription for a folic acid supplement and told me to take over the counter folic acid and a vitamin. So I have been taking these for 7 years. The maternal fetal doctor told me to take them for the rest of my life or at least until I am not able to have more children. They told me that it was why my son is so healthy and able to run and play. So this article confuses me because all of the information is different from what they told me. What should I do?

  6. Support Team

    Dear Veronica,

    Taking folic acid is better then not taking anything at all when comes to pregnancy, however L-Methylfolate is a more suitable format for MTHFR patients. To be on the safe side you should consult with a methylation expert. We have a directory of practitioners that can better help you with this issue. You should know how much to take also which varies depending on your MTHFR mutation and your serum folate levels.
