Methylation: A Deep Dive for Practitioners

Methylation has emerged as a hot topic in health – but what does it truly entail?

20 May, 2024


Methylation, a fundamental biochemical process, is rapidly gaining traction in health. It involves attaching methyl groups to DNA and proteins, acting as a cellular on/off switch. While seemingly minor, these tweaks significantly impact various bodily functions:

  • Nutrient Metabolism & Energy Production: Methylation influences how your body uses nutrients (like folate and B vitamins) to fuel cellular processes.
  • Mood & Brain Function: It regulates mood, sleep, and cognitive function through neurotransmitter production.
  • Detoxification & Repair: Methylation aids in eliminating toxins and supports DNA repair.
  • Hormone & Reproductive Health: It plays a role in hormone function and balance.

Suboptimal methylation can disrupt these processes, potentially leading to health concerns. Conversely, optimized methylation contributes significantly to overall well-being.

Folate and Methylation Connection

Folate, a crucial B vitamin, is essential for methylation. However, genetic variations in the MTHFR gene can affect how efficiently folate is converted to its active form, methylfolate.

Unlocking the Methylation Profile

DNA testing can reveal an individual’s methylation status by analyzing MTHFR and other relevant genes. This analysis helps identify strengths and weaknesses in methylation ability, guiding personalized nutritional interventions to optimize health.

Synthetic Folic Acid Considerations

Synthetic folic acid, commonly found in fortified foods and supplements, presents an interesting aspect. While MTHFR is a key player, other genes like DHFR and MTFHD also impact its metabolism. Analyzing these genes can help avoid potential issues with synthetic folic acid “bottlenecking” and hindering proper methylation. Research on the implications of synthetic folic acid supplementation for methylation is ongoing.


By unlocking genetic information, practitioners gain valuable insights into a patient’s methylation profile, paving the way for a more comprehensive approach to optimizing health.
