What Is The Best Multivitamin For MTHFR Mutation?

Many Americans may be MTHFR deficient and unaware of the same. MTHFR gene mutations can lead to nutritional deficiencies, fatigue, mental health issues, cardiovascular problems, and even neural problems in growing fetuses.

MTHFR deficiency can be handled with dietary supplements. Keep reading to learn the best multivitamins for MTHFR mutations and ways to combat the effects of the mutated gene.

What Is MTHFR?

The MTHFR (methylenetetrahydrofolate reductase) gene provides instructions for the production of the methylenetetrahydrofolate reductase enzyme.

This enzyme helps process various amino acids in the body. Amino acids are the building blocks of proteins.

The MTHFR enzyme helps convert an amino acid called homocysteine to methionine.

Methionine is an essential amino acid involved in hundreds of everyday operations at the cellular level.

The MTHFR enzyme also converts one form of folate (5,10-methylenetetrahydrofolate) into the active form called 5-methyltetrahydrofolate so the body can use it.

MTHFR Gene Mutations

Certain variations in the MTHFR gene can lead to MTHFR deficiency.

This condition is caused by low levels of MTHFR enzymes in the body due to impaired functioning of the MTHFR gene.

People with MTHFR gene mutations may have high levels of homocysteine and low serum folate levels.

One commonly noted Single Nucleotide Polymorphism (SNP) in the MTHFR gene is rs1801133.

People carrying the TT genotype of this SNP may have significantly high levels of homocysteine and lower levels of serum folate.

According to studies, about 25% of Hispanics and 10-15% of Caucasians in North America are born to have the TT genotype of this SNP and have an increased risk of developing MTHFR deficiency.

How Do MTHFR Mutations Affect Vitamin Requirements?

MTHFR mutations affect the ability of the body to convert folate into its usable form. So, people with MTHFR mutations may have folate or vitamin B9 deficiency.

Vitamin B12 requires the active form of folate to be absorbed by the body. As a result, folate deficiency can, in turn, lead to vitamin B12 deficiency.

While the MTHFR mutation doesn’t directly lead to vitamin B6 (pyridoxine) deficiency, there may be connections between these two.

A 2016 study reports that pyridoxine may help better recycle folate in the body and improve folic acid metabolism.

As a result, vitamin B6 may bring down the buildup of unmetabolized serum folic acid levels.

Health Conditions Associated With MTHFR Mutations

MTHFR mutations may cause B complex and other nutritional deficiencies. These may lead to various health conditions, including the following.

Anxiety, depressive disorder, and other mental health conditions
Higher risk of cardiovascular problems
Chronic pain and fatigue
Migraines
The risk of developing certain types of cancer
Increased risk of miscarriages
Neural tube defects in fetuses

The risk of developing the conditions depends on the type of MTHFR mutation present.

What Are Methylated Vitamins?

Methylated vitamins are specially formulated versions of certain B vitamins, like B12 and folate (B9), that are more easily absorbed and utilized by the body.

For some people, especially those with specific genetic variations, regular forms of these vitamins might not be efficiently processed, leading to deficiencies despite adequate intake.

Best Multivitamins for MTHFR Mutation

Since MTHFR mutations affect the way the body processes certain vitamins, one of the important ways of handling the condition is nutritional supplementation.

Methylated vitamins are some of the best multivitamins for MTHFR mutation. It is advised to consult with your doctor before you start on any new supplements.

Methyl folate

Since people with low levels of the MTHFR enzyme cannot process folate, they may benefit from picking up methyl folate supplements.

Methylfolate is a reduced and more active form of folate that the body can readily use.

Active Vitamin B12

Active vitamin B12 is B12 attached to a carrier protein called transcobalamin. This protein in the body helps transport vitamin B12 to the tissues.

This form of B12 is easily absorbed by the system, despite the levels of the MTHFR enzyme.

Active Vitamin B6

Pyridoxal-5-Phosphate (P5P) is an active form of vitamin B6 available as a supplement.

Like the other B complex supplements above, the active form of this vitamin is readily absorbed by the body and helps prevent vitamin B6 deficiency in people with MTHFR mutations.

Vitamin D3

Women with specific MTHFR gene mutations may have a higher risk of developing vitamin D deficiency.

A 2020 study reports that women with the homogenous MTHFR 677TT mutation had lower vitamin D levels than those with the CT and CC genotypes.

As a result, women with a mutated MTHFR gene may benefit from getting their vitamin D3 levels checked regularly to ensure they aren’t deficient.

NAC (N-Acetylcysteine)

NAC is an antioxidant and FDA-approved drug derived from the amino acid L-cysteine.

It is commonly used to treat respiratory conditions.

According to studies, NAC may help lower elevated levels of homocysteine in the body, helping convert this amino acid into its active proceeding form.

Glutathione

Glutathione is a type of antioxidant produced in all the cells in the body.

It plays vital roles, including eliminating free radicals, maintaining mitochondrial DNA, helping detoxify the body, and acting as a cofactor for different enzymes.

Homocysteine must be converted into its active form, cysteine, which is then required to produce glutathione.

In people with MTHFR mutation, homocysteine conversion doesn’t happen. This may lead to glutathione deficiency too.

Magnesium

While the MTHFR mutation does not cause magnesium deficiency, this mineral may help reduce cardiovascular risk in people with this gene mutation.

MTHFR mutation increases the risk of heart attacks and strokes. Magnesium can reduce these risks.

Migraines are also a common side effect of low levels of MTHFR enzymes, and magnesium helps with migraines too.

Methylated Vitamins For Kids

Methylated multivitamins may offer benefits like better energy levels and increased mental clarity for kids, especially those with MTHFR mutations.

However, multivitamins can have side effects like headaches and stomach issues.

Consult a qualified pediatrician before starting your kid on any supplements.

Methylated Multivitamin For Men

While folic acid is often discussed in the context of pregnancy and for females, the benefits of methylated vitamins for men are not out in the open.

However, excessive intake can lead to side effects, and folic acid can interact with certain medications. It's important to consult a healthcare provider before starting any supplementation regimen.

Some potential benefits include:

May benefit males with depression, particularly when combined with antidepressant
May reduce heart disease risk
May prevent premature graying - more research is needed for substantiation
Along with zinc supplementation may improve sperm quality and motility in subfertile males - however, research so far has yielded mixed results

Genes and Nutritional Deficiencies

Do B12 Shots Work For MTHFR?

Vitamin B12 shots may be one of the best ways to improve B12 absorption by the body.

When compared to oral B12 supplements, shots are quick-acting. These don’t have to be taken as frequently as oral supplements too.

Different types of B12 shots are available, and your doctors may be able to identify the best one for your needs.

Cyanocobalamin - This is a synthetic form of vitamin B12 and may not be easily broken down in the bodies of people with MTHFR mutations.
Hydroxocobalamin - Hydroxobalamin is a more bioavailable form of vitamin B12. Hydroxocobalamin injections are commonly chosen for people with MTHFR mutations.
Methylcobalamin - Methylcobalamin is also a highly active form of vitamin B12. The body can easily absorb the injection form of methylcobalamin.

Best Supplement Composition for MTHFR A1298C Variant

The MTHFR A1298C variant may increase the risk of colon cancer and schizophrenia.

A supplement composition of vitamin B6, B12, folate, and glutathione or methionine may benefit people with the MTHFR A1298C variant and reduce cancer and mental health risks.

Best Supplement Composition for MTHFR C677T Variant

Individuals with the MTHFR C677T variant may have higher homocysteine levels in the body. Vitamin B12 supplements or shots may help bring these levels down.

FAQs About Best Multivitamin For MTHFR Mutation

Should I Take B12 If I Have MTHFR Mutation?

If you have an MTHFR mutation, supplementing with vitamin B12 may be beneficial, as these mutations can impair your body's ability to utilize B12 effectively, potentially leading to deficiency symptoms and elevated homocysteine levels. However, it's important to consult with a healthcare provider to assess your specific needs and determine the appropriate dosage and form of supplementation.

Which Methylfolate Is Best For MTHFR?

For individuals with MTHFR mutations, L-methylfolate (5-MTHF) is generally considered the best form of folate supplementation, as it bypasses the metabolic issues associated with these mutations. L-methylfolate not only effectively increases circulating folate levels but also helps reduce homocysteine levels, which is crucial for cardiovascular health.

Why Are Methylated Vitamins Better?

Methylated vitamins are already in their active, bioavailable form, making them more easily absorbed and utilized by the body compared to non-methylated forms that require conversion. This can be problematic for individuals with genetic variations such as MTHFR mutations.
