Are you struggling to manage your blood pressure, even with a healthy lifestyle? What if a simple, naturally occurring compound could be the key to unlocking better cardiovascular health?

In a viral episode (#2060) of The Joe Rogan Experience, human biologist Gary Brecka detailed how Trimethylglycine (TMG) might be a game-changer for millions. He broke down the science of methylation, its link to the hidden risk factor of high homocysteine, and why a simple blood test could change your health trajectory. This guide unpacks his key insights and gives you the actionable steps to take control.

Key Takeaways from this Article:
  • Most high blood pressure cases are linked to genetic and biochemical factors.
  • High homocysteine levels are a major "silent" risk factor for heart disease.
  • Poor methylation, sometimes due to an MTHFR gene mutation, causes homocysteine to rise.
  • TMG (Trimethylglycine) is a "methyl donor" that can help lower homocysteine.
  • A simple blood test can reveal your homocysteine levels.

The “Silent Killer”: Why High Blood Pressure is So Sneaky

High blood pressure, or hypertension, often shows no symptoms until serious damage has occurred. Brecka highlights a crucial point: only about 15% of cases are “secondary,” meaning they’re caused by another obvious medical condition. For the other 85%, the root cause is often hidden in our unique biochemistry.

One of the primary culprits he identifies? Elevated homocysteine, an amino acid that, in high concentrations, can damage the lining of arteries and increase the risk of blood clots.

Who is Gary Brecka?

Gary Brecka is a human biologist and the co-founder of 10X Health System. He specializes in a proactive, data-driven approach to health, focusing on optimizing the body’s function based on biomarkers and genetic testing. His work with high-profile clients like UFC President Dana White has brought his methods into the mainstream.


The Science Explained: Methylation and Homocysteine

To understand why TMG is important, you first need to understand methylation.

Methylation is a fundamental biochemical process happening billions of times per second in your body. Think of it as a switch that turns on and off crucial bodily functions. It’s responsible for:

  • DNA Repair: Protecting your genetic code.
  • Detoxification: Helping your liver process toxins.
  • Neurotransmitter Production: Affecting your mood and mental clarity.
  • Regulating Homocysteine: Keeping this inflammatory compound in check.

The MTHFR Gene Connection

Some people have a common genetic variation known as an MTHFR mutation. This mutation can reduce the body’s ability to process folic acid into its usable form, methylfolate. This bottleneck impairs the entire methylation cycle, a process that also heavily relies on B-vitamins. For this reason, many people with this variant also benefit from a high-quality methylated B-Complex supplement to provide the necessary cofactors for healthy methylation. When methylation is impaired, homocysteine isn’t converted properly and its levels rise, increasing cardiovascular risk.


TMG: The “Methyl Donor” Solution

This is where Trimethylglycine (TMG) comes in. TMG, also known as betaine anhydrous, is a compound rich in methyl groups. Its primary job is to provide a “shortcut” in the methylation cycle by donating a methyl group directly to homocysteine, converting it back into a useful and harmless amino acid (methionine).

By supporting this crucial conversion, TMG can:

  1. Drastically Lower Elevated Homocysteine Levels.
  2. Support Healthy Cardiovascular and Arterial Function.
  3. Improve Energy Production and Metabolic Health.

Brecka famously cited the case of Dana White, who presented with dangerously high blood pressure and triglycerides. After genetic testing revealed methylation issues, a regimen including TMG helped normalize his health markers, showcasing its powerful potential.

Natural sources of TMG like beets and spinach


Your Action Plan to Optimize Methylation

Brecka’s approach is all about testing, not guessing. Here’s how you can apply these insights.

Step 1: Get Tested

Ask your doctor for a blood test to check your homocysteine levels. If you prefer to test from home, services like LetsGetChecked offer comprehensive wellness panels. Discussing the results with a healthcare professional is key.

Step 2: Incorporate Methylation-Supportive Foods

Before jumping to supplements, you can boost your intake of natural methyl donors. Excellent sources include:

  • Beets (especially beetroot)
  • Spinach and other leafy greens
  • Quinoa
  • Eggs and liver (rich in B-vitamins)

Step 3: Consider Targeted Supplementation

If your homocysteine levels are high, a targeted supplement protocol may be beneficial. Always consult with a healthcare provider before starting a new regimen.
