"Is it possible for people to be low in L-Methyl Folate [5-MTHF] even if they do NOT have single nucleotide polymorphisms affecting the MTHFR enzyme?"

The answer is... YES.

DIET
A person can have terrible nutrition. Someone who doesn't eat anything green. Someone who never eats beans. A poor diet low in DiHydroFolate [DHF] can cause there to be insufficient L-Methyl Folate.

MEDICATIONS
This includes thousands of people on coumadin [warfarin] who avoid eating greens and people with Rheumatoid Arthritis [RA] who have been given Methotrexate. Methotrexate blocks the enzyme that converts DHF into TetraHydroFoalte [THF ... ..more

MTHFR C677T and A1298C…how they don't work correctly By Carol Savage
………………….

MTHFR C677T...METHYLATION CYCLE...Epigenetics [SAMe and methylation of our DNA]

The MTHFR C677T snps causes the enzyme to be unable to utilize the cofactor FAD/FADH2 properly. The snp mistake [C677T] causes the enzyme to be temperature labile. As a result, the cofactor FAD disengages and subsequently L-Methyl Folate [5-MTHF] cannot be made. So, MTHFR C677T interferes with the forward action of the MTHFR enzyme and subsequently interferes with the conversion of Homocysteine into Methionine and the making of SAMe.

L-Methyl Folate is most beneficial to ... ..more

MTHFR and L-METHYL FOLATE… Some Basic Information By Carol Savage M.D.

If you have the MTHFR Gene Mutations C677T and or A1298C and are already taking some L-Methyl Folate [5-MTHF] and Vitamin B12 you might also consider the following:

FOOD Eat plenty of Green Vegetables and beans to get some Dihydrofolate [DHF] and Vitamin B2 [Riboflavin] and many other naturally occurring minerals and vitamins that the body needs etc.

DIHYDROFOLATE [DHF] Dihydrofolate is needed to provide the earlier FOLATE PATHWAYS [the reactions that occur prior to the MTHFR enzyme] with the kinds of folates that they need in order ... ..more

What is MTHFR A1298C Gene Mutation ?

  3 years, 1 month ago

By Helen Janneson Bense

A1298C single nucleotide polymorphism (SNP) affects the enzyme known as 5,10 MethyleneTetraHydroFolate Reductase (MTHFR). This polymorphism involves a down regulation of the MTHFR enzyme, responsible for the backwards reaction of the folate cycle, where 5-methylfolate (5MTHF) is converted into tetrahydrofolate (THF). This reaction is most important for the production of BH4 – tetrahydrobiopterin. Each turn of the folate cycle and conversion of 5MTHF to THF produces 1 molecule of BH4. In heterozygous and homozygous states, enzyme activity will be compromised by
approximately 30% and 70% respectively.

Functions of BH4
Cofactor for all three isotypes of nitric ... ..more

I found this excellent description in Amy Yasko's forum: ch3nutrigenomics.com. It was posted by one of the members on the site- raji: http://www.ch3nutrigenomics...
This is a private blog, but it is a very rich source of information about methylation, nutrigenomics and dietary supplementation

Here is a copy of the post:

1. Start eating 'clean'. Organic, non-GMO home made meals should become a priority. Eliminating #gluten and dairy to relieve your body from the burden of processing them should also begin.

2. Avoid taking any extra Folic Acid. There is already a lot of it in the nation's food supply, as it is added to [fortified] to many processed foods. If a person has the #MTHFR mutations then #L-Methyl Folate is the better choice. Choose this #supplement carefully.
Folic Acid will get turned into #Dihydrofolate and will be all gone, except for any more you may eat due to ... ..more

High dose #FolicAcid is the worst thing a person with the MTHFR gene mutation should take.
If a doctor tells a person with the #MTHFR gene mutations to take Folic ACID then that doctor does not really understand anything about the #L-Methyl Folate receptors on the Blood Brain Barrier [BBB]. The doctor does not realize that high dose Folic ACID is just going to block up the L-Methyl Folate Receptors on the BBB. When Folic ACID gets into the L-Methyl Folate Receptors it BLOCKS the receptor and it doesn't get into the brain and neither does the L-Methyl ... ..more

Folic ACID will get turned into Dihydrofolate and will be all gone... except for any more you may eat due to eating many fortified cereals and bread products.

A little Folic ACID will not be a problem. The problems occur when the amount of Folic ACID outweighs the availability of L-Methyl Folate regarding the BRAIN since Folic ACID blocks up the #L-Methyl Folate [ #5-MTHF ] #Folate Receptor Alpha receptors and prevents the real thing [5-MTHF] from getting into the brain.

The rest of the body doesn't suffer from too much #Folic ACID....only the brain.
Folic ACID is synthetic ... ..more

The major problem with unnatural synthetic FOLIC ACID is that when there is more #FolicAcid floating around in the blood stream than the real thing…L-Methyl Folate, then the excess Folic ACID can get stuck in the Folate Receptor Alpha [ #FRa ] receptor sites on the Blood Brain Barrier [BBB].

How the “FOLATE CYCLE” connects to the “ #BH4 TetraHydroBiopterine CYCLE” and how this influences the making of Neurotransmitters: #Melatonin, #Dopamine, #Norepinepherine and #Epinephrine [ #Adrenalin ].

Folic ACID completely blocks up the FRa receptor site on the BBB and the entire complex then has to be completely broken down to be recycled.

MULTICHEMICAL SENSITIVITY…and #MTHFR
#Methyltetrahydrofolate [MTHFR]
The MTHFR Enzyme is in charge of making #L-Methyl Folate which is the final product of that enzymatic reaction.
L-Methyl folate [5-MTHF] is needed to convert #HOMOCYSTEINE into #Methionine.

HOMOCYSTEINE
With an insufficient amount of L-Methyl Folate there may be a buildup of HOMOCYSTEINE. Too much Homocysteine can cause all sorts of problems such as:
1. Increased blood clotting
2. Irritation and damage to the intima [inner lining of blood vessels]
3. Interfere with cartilage development and healing
As a result of the elevated HOMOCYSTEINE the person will be at greater risk of ... ..more

MTHFR C677T Mutation: Basic Protocol by Dr Lynch on February 24, 2012 in C677T MTHFR Mutations
Have one or two copies of the MTHFR C677T mutation? Don’t know what to do?

After working with 100′s of individuals with this defect, I’ve developed a protocol which may help a significant number of people.
I want to make it absolutely clear that while the MTHFR C677T mutation may be common across a number of individuals, the outcome of supplementing with various nutrients can vary tremendously due to other genetic defects, dietary and lifestyle choices and environmental exposures.

Eating lots of dark green leafy vegetables will be a big benefit as well so we can get some Vitamin B2 [ 3Riboflavin ] which is needed by the #MTHFR Enzyme to have an adequate amount of its co-factor [helper/ Flavin Adenine Dinucleotide [ #FAD ]]

VITAMIN B2 [ #Riboflavin ] is important for the making of #Flavoproteins [FAD] which are cofactors in many biochemical reactions including the biochemical reaction involving the enzyme #MethylTetraHydroFolateReductase [MTHFR] enzyme.

#VitaminB2 is needed to help make FAD which is a cofactor for MTHFR enzyme so that the MTHFR enzyme can better convert #5-10-MethyleenTetraHydroFolate into #L-Methyl Folate.

WHAT IS MTHFR?

  3 years, 5 months ago

MTHFR is a a key enzyme necessary for the metabolism of folate, an important B vitamin. In other words, MTHFR most often refers to a genetic mutation that affects our ability to methylate or convert folic acid from the food we eat, or supplements we take into Methylfolate (L-MTHF). L-MTHF is referred to as the "active" or usable form of folate that is required by our cells. Since our body's cells cannot utilize folic acid, it must go through a metabolic pathway or 4-step process to become converted into Methylfolate (L-MTHF) so our cells can use it. It is ... ..more

What does a CBS Gene Mutation mean ?

  3 years, 4 months ago

CBS (cystathionine beta synthase) catalyzes the first step of the transsulfuration pathway, from homocysteine to cystathionine. Dr. Yasko considers addressing CBS mutations as first priority aside from addressing the gut.
This enzyme converts homocysteine to cystathionine. In a separate reaction, cystathionine is then converted to cysteine which in turn goes to taurine or glutathione among other things.

CBS defects are actually upregulations. This means the enzyme works too fast. Therefore, it is common to see low levels of cystathionine and homocysteine since there is a rapid conversion to taurine. This leads to high levels of taurine and ammonia.

The upregulation ... ..more

When you ask your doctor to write a script for #Deplin [15 mg of L-methyl folate] you can try to see if your insurance will cover it. Some do, but most do not because they want to call it a Medical Food. Which in my opinion is bogus. A food would be something you could find in nature and eat it. L-methyl folate doesn't exist in nature. Green leafy vegetables have Dihydrofolate not L-methyl folate...and Folic ACID is also not found in nature and is completely a SYNTHETIC CHEMICAL made by man.

So, in reality L-methyl folate and ... ..more
