Overmethylation occurs when there are too many methyl groups, which are small chemical units, added to DNA and other molecules in the body. This can influence how genes are turned on or off. 

In terms of health impact, overmethylation can lead to high levels of certain brain chemicals like serotonin, dopamine, and norepinephrine, potentially causing symptoms such as anxiety, mood swings, paranoia, and depression.

Physically, it can result in fatigue, headaches, and sleep disturbances. Additionally, individuals with overmethylation might be more prone to allergies or sensitivities to foods and chemicals. 

Natural treatment options for overmethylation focus on balancing methylation levels through non-invasive, holistic approaches. These include dietary changes rich in folate and B vitamins, supplements like vitamin B12 and SAMe, and lifestyle modifications such as stress reduction, regular exercise, and adequate sleep.

Working with a healthcare provider to develop a personalized treatment plan tailored to one’s genetic makeup and symptoms is essential. Additionally, a DNA methylation genetic test can provide valuable insights and guide appropriate interventions.

What is Overmethylation?

Overmethylation is characterized by an excessive addition of methyl groups to the DNA molecule, particularly at cytosine-phosphate-guanine (CpG) sites. This process results from an overactive DNA methyltransferase enzyme, which adds methyl groups to the DNA. 

Overmethylation is linked to the silencing of gene expression, as the added methyl groups prevent the binding of transcription factors necessary for gene activation. This condition is often associated with certain cancers and genetic disorders, as abnormal methylation patterns can disrupt normal cellular functions. It is caused by a variety of factors, including genetic predisposition, environmental influences, and dietary factors. 

Methylation plays a crucial role in cellular processes and overall health, with the methylation cycle being fundamental to regulating gene expression and maintaining genomic stability. This cycle involves the addition of methyl groups to DNA, proteins, and other molecules, impacting various biological functions. 

Scientists have extensively studied methylation to understand its implications for health and disease. Methylation is associated with the regulation of gene activity, ensuring that genes are expressed at the right times and in appropriate amounts.

Aberrations in the methylation cycle can lead to various diseases, including cancers, cardiovascular conditions, and neurological disorders. Studies have shown that abnormal methylation patterns, such as overmethylation or undermethylation, can disrupt normal cellular functions, contributing to the development and progression of these diseases. 

What Causes Overmethylation?

Genetic factors: 

  • Mutations or alterations in genes that code for DNA methyltransferases, enzymes responsible for adding methyl groups to DNA, can lead to increased methylation activity.
  • Certain epigenetic patterns can be inherited from parents, leading to predispositions towards overmethylation.
  • Variations in genes involved in the methylation cycle, such as MTHFR (methylenetetrahydrofolate reductase), can affect methylation processes and lead to abnormal methylation patterns.

Environmental factors:

  • Diet
  • Exposure to toxins and pollutants
  • Stress and hormonal imbalances
  • Certain medications and drugs
  • Aging

Genetic predispositions and environmental influences can disrupt methylation pathways, leading to either overmethylation or undermethylation. To explore how these two conditions compare and contrast, check out our article on overmethylation vs. undermethylation.

Mutations in DNA methyltransferase genes inherited epigenetic changes, and polymorphisms in methylation-related genes can cause excessive methylation, silencing essential genes. Environmental influences, such as methyl-rich diets, toxins, chronic stress, hormonal imbalances, medications, and aging, can further exacerbate this issue, resulting in the overmethylation of critical genes.

Overmethylation Symptoms
