If you follow Gary Brecka, you’ve probably heard of the MTHFR gene. He’s done a fair amount of content on the topic and has made many people aware of the complications and effects that an MTHFR gene mutation can have on someone.
We’re going to break things down further for you and help you understand what the MTHFR gene is, the symptoms of an issue, and what you can do if you have an MTHFR gene mutation.
Let’s start off by painting a picture for you.
Imagine a single gene in your body holding the potential to influence your risk for heart disease, mental health disorders, and even complications during pregnancy. This gene, known as MTHFR, plays a key role in your body’s ability to process vital nutrients and maintain cellular health.
However, variations and mutations of the MTHFR gene can lead to several potential health issues, often hidden beneath common symptoms like fatigue, mood swings, and chronic pain, which we all assume is just our body showing our true age.
In this article, we are going to dive deeper into the MTHFR gene, exploring how it impacts your well-being and what steps you can take to manage its effects to help optimize your overall health and wellness.

What is the MTHFR Gene?
If you were to poll American adults, I’d place a guess that probably over 90% of them have never heard of the MTHFR gene. And that’s fine, but you’re here because you want the details.
The most simplistic way to explain it is that the MTHFR gene provides instructions for making an enzyme called methylenetetrahydrofolate reductase (MTHFR).
This enzyme plays a crucial role in processing amino acids, which are the building blocks of proteins that have many vital functions in the body — the most commonly known is the ability to help repair and build muscle. This enzyme aids with the conversion of the amino acid homocysteine to methionine, a building block for proteins and other important compounds.
Below is a more detailed look at the key aspects of the MTHFR gene and its functions:
1. Function and Importance
- Homocysteine to Methionine Conversion: The MTHFR enzyme helps convert homocysteine (which can actually be toxic at high levels) into methionine, an essential amino acid used in protein synthesis and other metabolic processes.
- Folate Metabolism: MTHFR plays a critical role in the folate cycle, which is important for DNA synthesis, repair, and methylation. Folate (vitamin B9) is crucial for cell division and growth, especially during pregnancy.
2. Genetic Variants and Health Implications
- Common Variants: There are common polymorphisms (genetic variations) in the MTHFR gene, such as C677T and A1298C, which can affect the enzyme’s activity. The C677T variant is particularly well-studied.
- Reduced Enzyme Activity: Individuals with certain MTHFR gene variants may have reduced enzyme activity, leading to higher levels of homocysteine in the blood (hyperhomocysteinemia). This condition is associated with an increased risk of cardiovascular diseases, pregnancy complications, and certain types of cancers.
- Neural Tube Defects: Adequate folate levels are essential during pregnancy to prevent neural tube defects in the developing fetus. Variants in the MTHFR gene may increase the risk of these defects if folate levels are insufficient.
3. Testing and Management
- Genetic Testing: Genetic tests can identify MTHFR variants. Such tests are particularly relevant for individuals with a family history of cardiovascular diseases or recurrent pregnancy loss.
- Diet and Supplementation: Individuals with MTHFR variants may benefit from dietary modifications and supplementation. Increasing folate intake through diet or supplements, especially in the form of methylfolate (the active form of folate), can help mitigate potential health risks.
- Lifestyle Factors: Managing homocysteine levels also involves lifestyle factors such as regular exercise, avoiding smoking, and reducing alcohol consumption.
Better understanding the role of the MTHFR gene and its variants can help in personalized health management and preventive strategies, particularly for conditions linked to folate metabolism and homocysteine levels.
What Are the Symptoms of the MTHFR Gene?
Despite what you may assume, the MTHFR gene itself does not cause you to experience symptoms directly, but certain gene variants can lead to health issues due to reduced enzyme activity.
This reduction in enzyme activity can affect your body’s homocysteine metabolism and folate levels. Elevated homocysteine levels (hyperhomocysteinemia) and impaired folate metabolism are linked to various health issues.
Symptoms and Health Conditions Associated with MTHFR Variants
Below are some of the symptoms and health conditions you may experience with an MTHFR gene mutation.
If you feel you suffer from any of the following, it is recommended that you speak to your doctor.
1. Cardiovascular Issues
- Elevated Homocysteine Levels: High homocysteine levels can damage blood vessels, leading to an increased risk of cardiovascular diseases, such as coronary artery disease, heart attacks, and strokes.
- Blood Clots: There is a higher risk of developing blood clots (thrombosis) due to hyperhomocysteinemia.
2. Neurological and Psychiatric Symptoms
- Cognitive Decline: There may be an increased risk of cognitive decline and dementia due to poor blood flow to the brain.
- Mental Health Disorders: Some studies suggest a link between MTHFR variants and conditions like depression, anxiety, bipolar disorder, and schizophrenia, possibly due to altered neurotransmitter metabolism.
3. Reproductive Issues
- Pregnancy Complications: Women with MTHFR variants may have an increased risk of recurrent miscarriages, preeclampsia, and other complications during pregnancy.
- Neural Tube Defects: Reduced folate metabolism can lead to neural tube defects in the developing fetus, such as spina bifida.
4. General Symptoms Related to Folate Deficiency
- Fatigue and Weakness: Low folate levels can cause anemia, leading to fatigue and general weakness.
- Developmental Delays: In children, folate deficiency can result in developmental delays and learning difficulties.
5. Other Potential Health Issues
- Chronic Pain and Fibromyalgia: Some individuals report chronic pain and fibromyalgia-like symptoms.
- Migraines: Evidence suggests a link between MTHFR variants and an increased risk of migraines.
What Actions Can You Take?
For starters, you should always speak to your doctor and go through the proper tests. The internet does not provide you or me with a medical degree. So, it’s always wise to speak to a medical professional in these instances to ensure a proper diagnosis.
That being said, below are a few recommendations we have found to provide you with some further insight into what can be done and how it all works:
Diagnosis and Management for MTHFR Gene Mutations
- Genetic Testing: A blood test can identify specific MTHFR gene variants, such as C677T and A1298C.
- Blood Tests: Measuring homocysteine levels and folate status can help assess the impact of MTHFR variants.
Management Strategies for MTHFR Gene Mutations
- Dietary Changes: Increasing the intake of natural folate through green leafy vegetables, beans, and fortified foods can help. Supplementing with methylated folate (L-methylfolate) is often recommended instead of folic acid, especially for those with MTHFR variants.
- Vitamin B Supplements: Taking B vitamins, particularly B6 and B12, can help you lower homocysteine levels.
- Lifestyle Modifications: Regular exercise, avoiding smoking, and reducing alcohol intake can improve your overall health and mitigate some risks associated with MTHFR variants.
- Medical Monitoring: Scheduling regular check-ups with your doctor to monitor your homocysteine levels and overall health is important.
Navigating the MTHFR Gene is Challenging but Manageable
Understanding the MTHFR gene and its variations provides valuable insights into managing your health. By recognizing the symptoms and potential risks associated with MTHFR gene mutations, you can take proactive steps through diet, supplementation, and lifestyle changes to mitigate their impact.
Staying informed and working with healthcare professionals to monitor and address any concerns can help ensure you maintain optimal health and well-being despite potential genetic challenges. With the right knowledge and approach, you can turn genetic insights into actionable health strategies.
