Methylwho? Why You Should Know About Methylation

There have been at least 5 studies (3 randomized, controlled trials) looking at using methylfolate as a treatment for depression, either by itself or in addition to medication.  Most of these trials employed high doses (up to 50mg) of methylfolate and had partial to notable response rates. 

Need to Know For Pregnancy

When I first started testing for this variant (now available at commercial labs like Quest and typically covered by insurance), I noted that obstetricians in the city would also test patients, but only after 3 miscarriages.  Methylation problems such as those caused by this variant and other related variants can cause neural tube defects, increased risk for trisomy, heart defects, and now expanding to schizophrenia and autism.  In many ways, thoughtful and conservative supplementation with methylation support is in the best interest of mom's mood and baby, and is top of my list for perinatal interventions, supported by papers such as this.

One study looked at folic acid supplementation in the women with the C677 mutation and found that there was a decreased incidence of postpartum depression by 21 months after birth.  An interesting study in pregnant patients found an increased incidence of depressed mood in the second trimester in women with the C677TT variant, and that both their and their infant's serotonin transporters were methylated or expressed in ways that could conceivably affect behavior.

Folic Acid is Not Methylfolate

Synthetic folic acid does not exist in the human body.  It is found in vitamins, and thanks to the FDA's wisdom, in enriched flour-based foods (yet another reason to shun flour!).  Multiple enzymatic steps are necessary to convert folic acid into its active form beginning with dihydrofolate reductase in the gut.  Individuals with gene variants, but specifically homozygous C677 should avoid folic acid because of the concern for limited breakdown and subsequent accumulation of this man-made agent.  One study has implicated folic acid in suppression of important immune factors called natural killer cells. Folic acid binds more readily to receptors in the placenta and mammary epithelium, and may competitively inhibit or interfere with the functionv of usable, active folate. Currently, commercial testing of blood folate does not distinguish between metabolized and unmetabolized forms. There is also concern that folic acid supplementation can mask B12 deficiency by resolving the typical blood markers while methylfolate is not as likely to do this (although concurrent B12 supplementation is recommended).

Dr. Ben Lynch of, a tireless researcher on all things related to nutrigenomics, goes as far as to claim that folic acid should not be taken by any pregnant or nursing woman. He suggests that use of folic acid may be disturbing the forces of natural selection:

"Since women are now supplementing with increased levels of folic acid, they are more likely to carry to term and have improved methylation; however, once the infant is out of the enriched folic acid womb, it is on its own unless the parents supplement the infant with additional folate, b12 and other methylation support nutrients such as choline, b2 and b6."

Why there have never been folic acid vs methylfolate studies in pregnancy and in depression in the general population is unclear.

What's a Girl to Do?

First, get tested.

Then, depending on your degree of compromise, you'll want to look for a for a supplement that has says L-methylfolate in the ingredients, with the word Quatrefolic or Metafolin.  Starting with B12 in the form of methylcobalamin, and then introducing small doses of methylfolate and cofactors such as B2, B3, B6, trimethylglycine, and vitamin C is advocated for by Dr. Ben Lynch.  He discusses different products here and points out how unnecessarily riddled with toxic additives the prescription forms are.

He also discusses that, if you do have an adverse reaction to methylfolate (agitation, increased anxiety, headache), you can take nicotinic acid or niacinamide in 50mg dosages every 30 minutes until you experience relief.  B3 requires SAMe for its metabolism, and can thereby contribute to a drop in methylation.  It is also a cofactor for COMT, an enzyme that breaks down norepinephrine, epinephrine, and estrogen, all potentially elevated in states of anxiety.

It hopefully goes without saying that oxidative stress from environmental pollutants, food allergens, poor sleep, and limited relaxation all increase the demand to the corrective efforts of methylation.  A clean diet, home, body, and mind are a part of this package.  There is rarely a one pill solution, pharmaceutical or nutriceutical.

This is an area of explosive research, evolving all the time, but an excellent example of the power to use environmental exposures, diet, and supplementation to reclaim control over your health.

A question and additions about the topic

Enlightening article !

What about use of methyl folate or other things in people with heart defects ?

I know and have read about people stopping auditory hallucinatons by avoiding cow(or A1) dairy, isn't it interesting ?

Also, animal products must contain mostly, if not nearly totally methyl folate as the form of the B-9 vitamin in them if I think right.

So true!  Charge terrain determines DNA and all biochemical activity...Detoxing is a great universal first step along with excessive indulgence of Vitamin C. If required nutrients are in place, raising charge raises all biochemical function.
