5-LMTHF is the only form of folate that bypasses the MTHFR enzyme entirely, Natural folate, folinic acid, and 5-LMTHF are all-natural forms of folate. Table 1 lists the current RDAs for folate as mcg of dietary folate equivalents (DFEs). Folinic Acid: Available in both capsule and lozenge formats, folinic acid is a non-methylated form of folate that converts quickly into the active L-5-MTHF form within the body. Even though methylfolate gets into the system faster, it doesn't actually begin to work faster than folic acid would because there is the extra step of demethylation before it can be utilized. When we have the MTHFR gene mutation, either in one gene or both, we experience a loss of the enzyme in the liver needed to turn folic acid into folate for the body to use. Unfortunately, 50% of women cannot fully absorb folic acid because the MTHFR enzyme in their body, which is responsible for this . The C677T polymorphism typically reduces conversion efficiency by ~35% per copy and A1298C reduces conversion by ~20% per copy. Food folate is found in leafy green vegetables, legumes, citrus fruit, and in egg yolks and liver. You'll get a better lab test (higher folic acid numbers) , but a smaller benefit. Just like your body must convert folate into methylfolate, it must also convert folic acid into methylfolate. The difference between folate and folic acid. Both are forms of vitamin B9, but folic acid is the synthesized version, commonly found in processed foods and supplements. December 2016 in Infertility. L-methyl folate and 5-MHTF are two different terms . Let's now discuss the major differences between folate and folic acid and why certain brands may choose to use folic acid within food products or supplements. External supplementation of folate may occur as folic acid, folinic acid or 5-methyltetrahydrofolate (5-MTHF). That advice demonstrates a lack of understanding about both MTHFR and folate. Folinic acid is easier for many MTHFR mutants to tolerate . Folate is the common form of vitamin B9 present in many whole foods, including leafy greens, beans, eggs, citrus fruit, avocados, and beef liver. MTHFR - friendly Folate (Methylated Folate Vs. Folic Acid )- Best Methyl Prenatal contains patented Quatrefolic L-Methylfolate for superior conversion. Folic acid is a synthetic form of vitamin B9 that's found in many supplements that are based on synthetic USP vitamins. Download PDF. In order for the body to use it, folic acid must be converted into the methyl folate enzyme, which is a process reliant on the MTHFR gene. The body does not use folic acid very efficiently, especially if you fall into the 60 percent of people that may have an MTHFR mutation. Folate naturally occurs in foods like . Folic acid is not present in whole foods (remember, it's manmade); it is only present in foods that are fortified with folic acid. The takeaway on folate vs. folic acid. Contrarily, methylated folate is found in whole foods, especially dark leafy greens. Folate is an umbrella term for a number of different compounds, and can include folic acid, folinic acid and 5-MTHF (also known as methylfolate, MTHF, and 5-methyltetrahydrofolate). MTHFR C667T . This B vitamin is an essential nutrient that supports neural tube development in pregnancy, and it has been well-studied for its ability to help prevent neural tube defects. The relationship between folate and ASDs is extremely complex overall because the low folate-dependent DNA hypomethylation can be due not only to a reduced intake but also to an altered folate metabolism , an example of which is the debated epigenetic role of MTHFR polymorphisms (C677T and A1298C) in the DNA methylation. The human body must do this conversion because it cannot use folic acid or folate in its basic form (chemical structure). Even if you have one or two copies of the MTHFR C677T variant, your body can safely and effectively process the different types of folate, including folic acid. Folate is a naturally occurring vitamin B9. MTHFR is an enzyme required to convert folic acid into an active form called L-methylfolate that is usable by our bodies. Methyl Folate vs Folic Acid. Unfortunately, many who have a genetic MTHFR mutation are unable to utilise these nutrients properly.. L-Methylfolate (5-MTHF) has emerged as a popular alternative, and has been used as a complementary medicine in several recent clinical trials. Introduction. Folate is an important B vitamin and works together with vitamin B12 to protect your health. There's a limit (diminishing returns) to how much folic acid your body can metabolize. What scientists know is that more methylfolate goes into cells than folic acid . jodes727 member. The MTHFR gene is involved in the conversion of folate (folic acid and food-derived folates) into the bioactive form, called methylfolate or 5-MTHF. And up to one-third of men and women have a genetic variation that can impact the last step of the conversion. How to Know if MTHFR is the Root Cause of your Child's ADHD - MTHFR Experts on The Breakdown of MTHFR It's confusing. Folate & Pregnancy, new issue on implications of MTHFR polymorphism 19 June 2017 Gnosis has published a new "News from Science" issue focusing on Quatrefolic® the "innovActive" folate and the MTHFR polymorphism in pregnancy, this way continuing its dedication to education and awareness on the world of folate. Folic acid makes natural folate and folinic acid less useful because it blocks receptor sites and slows down the methylation pathway. This can lead to a buildup of folic acid in the body, causing cardiovascular and other health issues. However, folic acid is processed in the liver and needs dihydrofolate reductase (an enzyme) to be processed. Folic acid is a synthetic form of folate which is often found in supplements and foods which have been fortified with the nutrient (e.g. Folic acid doesn't have to be demethylated, but methylated folate does. Folic acid is used most widely, because the vast majority of studies demonstrating clinical benefits of Regular doses of folic acid (100-200 μg) can be tolerated in the general population but should be abandoned in the presence of MTHFR mutations, as the biochemical/genetic background of the patient precludes a correct supply of 5-MTHF, the active compound. The human body, without the MTHFR enzyme, can't convert folic acid into methylfolate and it builds up in the body as endogenous toxins. Folic acid refers to the synthetic, oxidized compound that is often found in dietary supplements and foods fortified with Vitamin B9. I am trying to do research on folate vs methylfolate, but so many websites interchange folate with folic acid so it's hard to come up with a consensus on if natural folate, like in spinach, is the same as methylfolate or if it is affected by mthfr at all. Folic acid, the synthetic form of folate, must undergo enzymatic reduction by methylenetetrahydrofolate reductase (MTHFR) to become biologically active. Folate deficiency, of course, is harmful. Folate vs folic acid. Conclusion. At least 85% of folic acid is estimated to be bioavailable when taken with food, whereas only about 50% of folate naturally present in food is bioavailable [1 . Folic acid and folate are commonly, but incorrectly, thought to refer to the same compound. It is estimated that between 25 and 60 percent of the population have a variation in one of their MTHFR genes that negatively impacts their ability to convert folic acid (the synthetic version of B9), and even some of the folate that naturally occurs in foods, into the active form of folate. The methylenetetrahydrofolate reductase (MTHFR) enzyme converts synthetic folic acid and dietary folate into its active form, L-methylfolate, which plays a critical role in neurotransmitter synthesis. This type of deficiency is no longer a problem in many countries that fortify foods such as cereal and pasta with folic acid. People with the MTHFR mutation will have problems making that conversion, and find their folate receptors actually blocked by malformed folic acid enzymes. Folic Acid vs 5-MTHF. If you have the MTHFR mutation, your body is not able to convert folic acid into usable methyl-folate. Folate is processed in the small intestines into tetrahydrofolate. If you have an MTHFR mutation, you know your MTHFR enzyme has a 20-70% loss in function when converting 5,10-methylene-THF to 5-MTHF. It drops off around 260 mcg, and pretty much plateaus at 400mcg. Folic acid is the oxidized synthetic form of folate. Folate, vitamin B9, is used in the body for many things including detoxification, growth, energy, muscle building, brain function, and more ( source ). This reaction is also required to convert the amino acid homocysteine to another amino acid, methionine. It has been added to many foods such as cold cereals, flour, breads, pasta, bakery items, cookies, and crackers. Folate is abundant in green vegetables, beans and other whole plant foods. October 20, 2014 amelia833. Heart and blood vessel disease and stroke. MTHFR - friendly Folate (Methylated Folate Vs. Folic Acid )- Best Methyl Prenatal contains patented Quatrefolic L-Methylfolate for superior conversion. Read more about folate vs folic acid>> General Information About NTDs, Folic Acid, and Folate>> Folic acid is the only type of folate shown to help prevent neural tube defects. Genetic mutations of MTHFR result in a cell's inability to convert folic acid to 6(S)-5-MTHF. Hi ladies, I have MTHFR and my ob prescribed extra folic acid (folgard generic) in addition to my otc prenatal that also has folic acid. L-Methylfolate (5-MTHF) has emerged as a popular alternative, and has been used as a complementary medicine in several recent clinical trials. Folic acid is the synthetic version of this vitamin and is often found in multivitamins, fortified foods, and certain drugs. Folate is a generic name for a group of related compounds with similar nutritional properties. One of the major risks associated with an excessive amount . Vitamin B9, also known as folic acid or folate, plays a key role in fertility, pregnancy, and the health of the baby. Folic acid: the synthetic form of vitamin b9 is metabolised poorly by all people, not just those with MTHFR gene mutations. Folate exists in nature in several different forms. Folate vs Folic Acid. Folate is processed in the small intestines into tetrahydrofolate. L-methyl folate and 5-MHTF are two different terms . When we have the MTHFR gene mutation, either in one gene or both, we experience a loss of the enzyme in the liver needed to turn folic acid into folate for the body to use. The answer's simple - cost of production. About 40% to 60% of the population has genetic polymorphisms that impair the conversion of supplemental folic acid to its active form, l-methylfolate. Natural folate is beneficial when provided by whole foods, but may be harmful in supplement form as folic acid. Folic Acid vs L-Methylfolate. The caveat? Conclusion. Unfortunately, many who have a genetic MTHFR mutation are unable to utilise these nutrients properly. Folic acid is absorbed better in the digestive tract than food folate (5-MTHF and folinic acid are the food forms). It is only absorbed faster and still needs processing. 1. The active form of vitamin B9 is a folate known as levomefolic acid or 5-methyltetrahydrofolate (5 . Folic Acid. 1 Comment. The first basic of an MTHFR mutation is to AVOID FOLIC ACID AT ALL COSTS!!!! Folic acid is the synthetic version of this vitamin and is often found in multivitamins, fortified foods, and certain drugs. Notice the last step requires the MTHFR enzyme (blue box), produced by the MTHFR gene. [Last updated 14th October, 2021] Folate and folic acid are nutrients required for many critical functions in the body. . When you take a folic acid supplement, MTHFR converts the folic acid into L-methylfolate, also called 5-methyltetrahydrofolate (5-MTHF). It blocks the effects of SLC19a1 gene, DHFR gene, and MTHFR gene meaning that it prevents absorption and proper utilisation of folate, and hence blocks proper DNA synthesis and methylation. There is a low amount of this enzyme in the liver which means that most of folic acid doesn't get processed. Folate is the term used for a group of water soluble B Vitamins, also known as B9. Lower sperm quality. The best form of folate to take is the metabolically active form called L-methylfolate (also known as 5-methyltetrahydrofolate or 5-MTHF). A large percentage of women have a common defect in their MTHFR gene . Which is hilariously difficult if you live in the US like me because of american government regulations that force some of your favorite junk food and cereal producers to "fortify . Emerging science of nutrigenomics indicates that MTHFR most often refers to a genetic mutation that inhibits the ability of the body to methylate (or convert folic acid from the food we eat into the metabolite we need, L-5-Methyltetrahydrofolate) so as some individuals cannot . On the other hand, folic acid is a synthesized version of vitamin B9 that is added to processed foods and the common version used in supplements. The prenatal I recommend that contains absorbable folate: https://amzn.to/2Ek2sPu*Read more, find links to studies, and see the vitamins I recommend: https:/. The Food and Drug Administration (FDA) requires that manufacturers in the United States add folic acid to many foods, and 42 other countries around the world . MTHFR practitioners say that the human body needs to convert folic acid into a form of folate that the body can use. In order for the body to use it, folic acid must be converted into the methyl folate enzyme, which is a process reliant on the MTHFR gene. What is the big difference? Folic acid works with vitamins B-6 and B-12 to control high levels of homocysteine in the blood. [5,10] It is widely used in supplements and fortified foods due to its stability, although it needs to be reduced intracellularly to tetrahydrofolate (THF) in order to become . Folate is the naturally occuring and active form of vitamin B9 found in food. Folic acid is the synthetic form of folate that is commonly found in supplements. Serum folate consists of unmetabolized folic acid, dihydrofolate, tetrahydrofolate, folinic acid, L-5-MTHF. As a part of MTHFR gene mutation treatment, you should avoid consuming folic acid or the . On the other hand, folic acid is a synthesized version of vitamin B9 that is added to processed foods and the common version used in supplements. Micronutrient folate (vitamin B 9) has a vital role in human health and disease and is essential for several crucial cellular processes, including DNA synthesis, amino acid interconversion, various methylation reactions, and consequently, for normal cell division and growth.Folate deficiency is associated with several congenital malformations, such as neural tube defects (NTDs . The MTHFR gene codes for methylenetetrahydrofolate reductase, an enzyme. To use either food folate or folic acid, your body has to convert these into a metabolically active form of folate. Folic acid is the synthetic form of folate—found in most leading prenatal vitamin brands. Numerous terms are used to refer to folic acid and folate. The conventional use of large doses of folic acid (5 mg/day) has become obsolete. These defects related to MTHFR are very common, though they vary enormously between ethnic groups and regions [10, 11]. March 4, 2021; Blog Author - Mackenzie Amy Jaramillo - Scientific Director Scientific Director at Bodyscience.life Recent Comments. But, if you have an MTHFR mutation your body will often require more than 200 micrograms of folate per day. People with the MTHFR mutation will have problems making that conversion, and find their folate receptors actually blocked by malformed folic acid enzymes. Having an MTHFR gene mutation reduces your body's natural ability to produce its active form of folate. Answering your Questions: Can I Eat Folic Acid? Nutritional folate deficiency is treated with oral folic acid supplements. About 40% to 60% of the population has genetic polymorphisms that impair the conversion of supplemental folic acid to its active form, l-methylfolate. Folate vs Folic Acid. Variations in the MTHFR gene impact the efficiency of this conversion. You can get most or all of the folate you need from delicious plant-based foods. One copy of the T variant is associated with a 45% reduction in folic acid absorption. This potent formula contains 800 mcg DFE of folinic acid per capsule, and 1,360 mcg DFE per delicious lozenge. Methyl-Free Standalone Folate. Some individuals carry a mutation at the C677T SNP of the MTHFR gene, which results in a 35% reduction in activity for heterozygotes (C/T) and a . October 12, 2014. Below is a quick recap of the problems linked to low folate status: Neural tube defects. Folate, vitamin B9, is used in the body for many things including detoxification, growth, energy, muscle building, brain function, and more ( source ). In women who have the MTHFR mutation, folic acid gets "parked" outside cells because they can't absorb it, so it stays in the bloodstream. There is no research to suggest that it is not effective at preventing neural tube defects, and a number of studies to show that it is at least as effective as Folic Acid. While over 150 different forms of naturally occurring folate have been identified, 5-MTHF is the major type of folate found in food. Any suggestions on a brand that you like? Folate, folic acid and 5-MTHF. 1, 3, 4 . But excess in the form of folic acid has its own dangers. L-methylfolate plays an important role in making neurotransmitters such as serotonin, dopamine, and norepinephrine, which help regulate mood. The difference between folate and folic acid. I've been reading up on MTHFR and have come across a lot of info that says folic acid should be avoided and only folate should be taken vs the synthetic folic acid. The conventional use of large doses of folic acid (5 mg/day) has become obsolete. Folate and folic acid are two distinct compounds with two key differences in function: Folic acid is the synthetic form of folate, which is also called vitamin B9. Women with the MTHFR variant show a better response with plasma folate markers to methylfolate than to Folic Acid. Over the course of this year, there have been many articles about the benefits of folic acid vs L-5MTHF here in Australia and I think the writings have been somewhat one sided, so I have decided to send you my thoughts on the folic acid vs L-5MTHF debate. 3. Naturally occurring 5-MTHF has important advantages over synthetic folic acid - it is well absorbed even when gastrointestinal pH is altered and its bioavailability is not affected by metabolic defects. If you take folic acid instead, also aim for 800-1,000 mcg per day. for those of you who have the mthfr Gene mutation, have you switch to a vitamin that has folate in it instead of the folic acid? Although folate is often discussed interchangeably with folic acid, folic acid is a synthetic form of folate that has both benefits and risks. Both terms are used generically to refer to the folic acid contained in foods and supplements. Bread, baked goods, cereals or any other foods made with folate enriched wheat). Unfortunately the advice given to many patients with MTHFR gene mutations by medical doctors is "take extra folic acid". Folate vs folic acid and mthfr. I am trying to do research on folate vs methylfolate, but so many websites interchange folate with folic acid so it's hard to come up with a consensus on if natural folate, like in spinach, is the same as methylfolate or if it is affected by mthfr at all. Folate is the naturally occuring and active form of vitamin B9 found in food. The flawed reasoning goes like this: The patient has the MTHFR gene mutation; Since folic acid will build up in the folate cycle, there will be less folate making it through the final stage of the cycle which requires the MTHFR enzyme. Certain variants of the MTHFR gene affect the ability to convert folic acid so your body can absorb it. The FNB developed DFEs to reflect the higher bioavailability of folic acid than that of food folate. In conclusion, (1) folic acid is more bioavailable than food folate, (2) people with a MTHFR mutation are not required to take methyl folate, and (3) people with a MTHFR mutation can benefit from folic acid supplements in increasing folate level and reducing homocysteine level in the blood as much as people without mutation. Folic acid is the form used in many supplements because it's highly stable. You can get folate from foods that are high in folate, or from dietary supplements containing natural folate. Folic acid and folate can be cheap, but methylfolate tends to be the most effective option when it comes to treating the unique needs of MTHFR and giving the body an enzyme it can directly act upon. Taking prenatal vitamins with 800-1,000 mcg of methylfolate will help you maintain an adequate level of folate to support the baby's brain devleopment, regardless of your MTHFR gneetic status. The mechanism that over-dose folic acid induces higher risk of cancer is currently unknown, but some molecular epidemiologic studies show that genetic polymorphism in folate metabolic processes, such as MTHFR, directly modify cancer risk, or indirectly modify cancer risk through interaction with folate and other nutritious components in folate . Dr. Chris D. Meletis explains how genetics can determine how well your body metabolizes Vitamin B9. Regular doses of folic acid (100-200 μg) can be tolerated in the general population but should be abandoned in the presence of MTHFR mutations, as the biochemical/genetic background of the patient precludes a correct supply of 5-MTHF, the active compound. Folate compounds that are commercially available include folic acid, methylfolate (also known as L- methylfolate, 5-MTHF, and 5-methyltetrahydrofolate), and folinic acid (5-formyl tetrahydrofolate). However, folic acid is processed in the liver and needs dihydrofolate reductase (an . The term folate is a catch-all for any type of folate, whether natural or . The body does not use folic acid very efficiently, especially if you fall into the 60 percent of people that may have an MTHFR mutation. I am trying to do research on folate vs methylfolate, but so many websites interchange folate with folic acid so it's hard to come up with a consensus on if natural folate, like in spinach, is the same as methylfolate or if it is affected by mthfr at all. Once folic acid enters a cell, it needs to be converted into 6S-5-Methyltetrahydrofolate (MTHF) by several key enzymes before your body can use it. Folate vs. folic acid. Folate refers to the tetrahydrofolate derivatives that are naturally present in food. breads and cereals). This is not clinically useful information except only in the case of frank folate deficiency when serum folate is low. When you read about the problems caused by a lack of folate, it's due to a lack of the bodies active form of folate, 5-MTHF. . Folate is the common form of vitamin B9 present in many whole foods, including leafy greens, beans, eggs, citrus fruit, avocados, and beef liver. The difference is very important for pregnant women to understand. Just to be clear: folic acid is not the same as natural folate. Folic Acid Awareness Week. This is the biologically active form of folate; in other words, it's the type of folate our cells can use. Folic acid we eat must always go through this entire sequence (above image), from top left corner to the bottom step, L-methylfolate. L-methylfolate (chemically (6S)-5-Methyltetrahydrofolate) is the most pure, active form of methylfolate you can buy. Some people carry a mutation in the MTHFR gene, which limits their ability to . Folic Acid vs 5-MTHF in Treating MTHFR Deficiency. MTHFR is a gene that provides instructions to make an enzyme called methylenetetrahydrofolate reductase, a key factor in a chemical reaction that breaks down folate (or folic acid) to its active form, L-methylfolate (5-MTHF). Folic Acid vs Folate vs Methylfolate vs 5-MTHF vs … What Does It All Mean?? However, folic acid, the synthetic form of vitamin B9 (folate) is commonly found in fortified foods and (historically) in vitamin supplements. Folic acid is a synthetic, oxidised form of folate with a high degree of stability and an absorption rate of 85-95%, compared to 50% of folate from dietary sources. Folic acid can be found in supplements and fortified foods (ex. If methylfolate is found naturally, then why do companies use folic acid instead? As a result, taking folic acid can mean you're not absorbing as much food folate. Folate and folic acid are nutrients required for many critical functions in the body. The T variant of the rs1801133 genotype affects folic acid absorption and as a result can lead to folate deficiencies. We need less than 200 micrograms of folate per day!
