445 Methylfolate [6 Nov 2017]

Folate is a B vitamin (B9) with many essential roles in our metabolism. It is found in leafy green vegetables, hence the name folate after “folium”, Latin for leaf. Folate is also synthesized by certain lactobacillus and bifidobacteria bacteria in our small intestine.

Most of us have heard that folate is essential in pregnancy to prevent the birth defect spina bifida, but it plays many other roles. Folate:
• is essential in cell division and synthesis of DNA and RNA
• helps make the neurotransmitters serotonin, dopamine, and norepinephrine
• prevents neural tube defects (including spina bifida) in pregnancy
• helps prevent anemia in pregnancy
• converts homocysteine to less-toxic methionine (homocysteine increases inflammation and risk of heart disease)
• maintains healthy T cell production and therefore resistance to infections
• improved symptoms of depression, bipolar and schizophrenia
• improves cognitive function and slows brain deterioration in Alzheimer’s and dementia

The natural form, folate, is metabolized in the small intestine to the active form methyltetrahydrofolate (MTHF). The synthetic form, folic acid, found in “fortified” foods and cheaper vitamin supplements, requires conversion in the liver before a final conversion to THF. The liver process requires an enzyme, MTHFR, of which many people have inherited an inactive form. These people are unable to utilize folic acid or even some of the natural forms found in food. If they supplement with folic acid toxic levels could build up in their livers, so they need to use the methyl form. Are you one of them? Genetic testing could tell you – but a trial with MTHF would be easier and cheaper.

The ubiquitous herbicide glyphosate preferentially kills the folate producing bacteria in our gut so now it’s even more essential to get folate from our diet and supplements.

Similar to methylcobalamin being the preferred form of vitamin B12 [see #339], the preferred form of B9 is methyltetrahydrofolate. I’ve noticed recently that more of the higher quality B complex and multi vitamins have these forms of B9 and B12. Look for them when you are buying vitamins for yourself and your family.
