Undermethylation occurs when methylation activity is insufficient, disrupting gene expression and brain chemistry. This imbalance, often caused by reduced methyl donors like SAM or lower DNA methyltransferase activity, can lead to abnormal gene regulation.

It impacts neurotransmitter production, reducing serotonin, dopamine, and norepinephrine levels, which contributes to depression, anxiety, and cognitive issues. 

Undermethylation also affects histone methylation, altering chromatin structure and further disrupting gene activity. Symptoms range from psychological to physical, but treatments like vitamins, dietary changes, and stress management can restore balance. Understanding methylation’s role in health is key to addressing undermethylation effectively.

What is Undermethylation?

In biochemistry, undermethylation affects the methylation cycle, which is crucial for converting nutrients into active forms needed for various bodily functions. 

Key enzymes involved in this cycle, such as DNA methyltransferases and methylenetetrahydrofolate reductase (MTHFR), may not function optimally due to genetic mutations or nutrient deficiencies. 

This disruption leads to inadequate production of S-adenosylmethionine, a primary methyl donor, resulting in impaired methylation of DNA and histones. Consequently, gene expression becomes dysregulated, affecting cellular function and contributing to various health issues.

In psychiatry, undermethylation significantly impacts neurotransmitter synthesis and function. 

Neurotransmitters like serotonin, dopamine, and norepinephrine, crucial for mood and cognition, depend on adequate methylation for production and metabolism. Insufficient methylation can decrease these neurotransmitters, causing depression, anxiety, and cognitive decline. 

Additionally, undermethylation affects myelin production, leading to neuropsychiatric conditions and impaired neural transmission.

Prevalence and Risk Factors for Undermethylation:

  • Affects approximately 15-20% of the population, varying with genetic and environmental factors.
  • Genetic Predisposition: Mutations in genes like MTHFR increase risk.
  • Age: More common in older adults due to declining methylation efficiency.
  • Gender: Slightly higher prevalence in men.
  • Mental Health Disorders: Linked to conditions like depression, anxiety, OCD, and autism.
  • Chronic Health Conditions: Associated with cardiovascular diseases, chronic fatigue syndrome, and autoimmune disorders.
  • Nutritional Deficiencies: Higher risk with diets low in B vitamins (B6, B12, folate) and methyl donors.
  • Environmental Exposure: Susceptibility increases with exposure to toxins and pollutants.

What Causes Undermethylation?

Various genetic, dietary, and environmental factors can contribute to poor methylation. Identifying and addressing these factors is essential for improving methylation processes. 

For an in-depth look at these causes and how they affect methylation, check out our detailed article on poor methylation. 

Genetic Factors:

  • Mutations in the MTHFR gene, which is associated with reduced enzyme activity required for methylation.
  • Variants in other genes like MTR, MTRR, and CBS, are linked to impaired methylation cycles.

Dietary Factors:

  • Deficiencies in essential nutrients such as folate, vitamin B6, vitamin B12, and magnesium, are crucial for the methylation process.
  • Poor dietary intake of methyl donors like choline and methionine, is often associated with diets low in leafy greens, meat, and dairy.
  • High consumption of processed foods and alcohol, can deplete necessary nutrients.

Environmental Factors:

  • Exposure to environmental toxins and pollutants, such as heavy metals (lead, mercury) and chemicals (pesticides, bisphenol A), can disrupt methylation pathways.
  • Chronic stress is associated with elevated cortisol levels that can interfere with methylation processes.
  • Inadequate physical activity and poor lifestyle choices, can exacerbate undermethylation by affecting overall health and nutrient absorption.

Undermethylation affects critical biochemical pathways, particularly the folate and methionine cycles, leading to significant methylation issues and imbalances.  

Dr. William Walsh’s protocol is a prominent approach to understanding and treating undermethylation. His method focuses on identifying specific nutrient deficiencies and genetic predispositions that contribute to undermethylation. 

By customizing treatment plans that include supplements such as methylfolate, SAMe, and methylcobalamin, Walsh’s protocol aims to correct biochemical imbalances and improve mental health outcomes.

The folate cycle converts dietary folate into 5-methyltetrahydrofolate (5-MTHF), crucial for methyl group donation. Genetic mutations like MTHFR can impair this conversion, reducing 5-MTHF and hindering the methionine cycle. 

This cycle converts homocysteine to methionine, producing S-adenosylmethionine (SAM), the body’s primary methyl donor. Low SAM levels compromise DNA, protein, and neurotransmitter methylation, leading to improper gene expression and neurotransmitter synthesis.

Research has shown that these imbalances can contribute to various health issues, including mental health disorders, cardiovascular diseases, and chronic inflammation. 

Addressing these methylation issues through targeted nutritional and lifestyle interventions is crucial for restoring balance and improving overall health.

How to Test for Undermethylation

Blood Tests:

  1. Homocysteine Level Test: This test analyzes the level of homocysteine in the blood. Elevated homocysteine levels can indicate poor methylation status and are commonly used to identify undermethylation.
  2. Methylation Profile Test: This comprehensive test measures a range of methylation markers in the blood, including SAM (S-adenosylmethionine) and SAH (S-adenosylhomocysteine) levels, to assess overall methylation status.

Genetic Marker Tests:

  1. MTHFR Gene Test: This genetic test identifies mutations in the MTHFR gene, which are often linked to undermethylation. It is diagnosed by analyzing DNA to detect common variants such as C677T and A1298C.
  2. COMT Gene Test: This test identifies polymorphisms in the COMT gene, which can affect neurotransmitter breakdown and methylation processes, providing a more comprehensive view of one’s methylation status.

Nutrient Panel:

  1. Vitamin and Mineral Levels: This blood test measures levels of essential nutrients like folate, vitamin B12, vitamin B6, and magnesium. Deficiencies in these nutrients can contribute to undermethylation, and analyzing their levels helps identify specific supplementation needs.

Accurate diagnosis of undermethylation is crucial as it directly impacts the effectiveness of treatment and overall patient health. 

A precise diagnosis results in targeted interventions that can correct methylation imbalances, improve neurotransmitter function, and alleviate symptoms associated with undermethylation, such as depression, anxiety, and fatigue. 

Misdiagnosis, on the other hand, can lead to inappropriate treatments that fail to address the underlying issue, exacerbating the patient’s condition and potentially causing new health problems. 

For instance, treating symptoms without recognizing the underlying methylation issue may result in ineffective therapies and persistent symptoms.

Best Supplements to Take For Undermethylation

Recommended supplements for undermethylation include: 

  • Methylfolate (400-800 mcg daily, capsule or tablet)
  • Vitamin B12 (Methylcobalamin) (1000 mcg daily, sublingual tablet or liquid) 
  • Vitamin B6 (Pyridoxine) (50-100 mg daily, capsule or tablet)
  • SAMe (200-400 mg daily, enteric-coated tablet)
  • Folate (400-800 mcg daily, capsule or tablet), Zinc (10-25 mg daily, capsule or tablet).

Methylfolate, the active form of folate, acts as a donor of methyl groups in the conversion of homocysteine to methionine, a key step in DNA methylation. By directly providing methyl groups, methylfolate supports the proper functioning of methylation pathways, which are critical for gene expression and overall cellular health. Its bioavailability makes it particularly effective compared to other forms of folate.

Vitamin B12 in its methylcobalamin form is crucial for the remethylation of homocysteine to methionine, which is a vital step in the methylation cycle. Methylcobalamin acts as a cofactor for the enzyme methionine synthase, facilitating the transfer of a methyl group to homocysteine. This process not only helps maintain healthy homocysteine levels but also ensures the continuous production of S-adenosylmethionine (SAMe), a key methyl donor in numerous biochemical reactions.

Vitamin B6, particularly in its active form pyridoxal-5′-phosphate (PLP), is essential for the conversion of homocysteine to cysteine. This step is crucial for maintaining a balance in the methylation cycle, as it helps regulate homocysteine levels and prevent their accumulation. By supporting the efficient conversion of homocysteine, Vitamin B6 indirectly facilitates proper methylation processes.

SAMe is a primary methyl donor involved in numerous methylation reactions throughout the body, including DNA, RNA, proteins, and phospholipids. It is synthesized from methionine and ATP, and its availability directly influences the efficiency of methylation processes. 

Folate is a B-vitamin that is crucial for DNA synthesis, repair, and methylation. It serves as a precursor to methylfolate, which is necessary for the transfer of methyl groups in the methylation cycle. 

Adequate folate levels ensure the proper function of enzymes involved in methylation, thereby supporting genetic stability and cellular health. 

Zinc is a vital cofactor for numerous enzymes involved in DNA synthesis and repair, as well as for those regulating the methylation cycle. 

It plays a crucial role in the structure and function of DNA-binding proteins and influences gene expression. Adequate zinc levels are necessary for maintaining the activity of DNA methyltransferases, which add methyl groups to DNA.
