# Exploring the Remarkable Benefits of Trimethylglycine (TMG)
Written on
Chapter 1: Introduction to Trimethylglycine
Trimethylglycine (TMG), commonly referred to as betaine, is gaining recognition for its potential in enhancing cardiovascular, metabolic, and mental health, and may even improve athletic performance.
Cardiometabolic diseases impact millions globally, with high homocysteine levels and chronic inflammation being major risk factors. Research has linked TMG to heart health, indicating that maintaining balanced homocysteine levels is essential for optimal cardiovascular performance. Though TMG has been acknowledged for its heart-health benefits since the 1950s, it remains relatively unknown compared to more commercialized supplements.
Recently, I wrote an article titled "MTHFR Polymorphisms or Mutations: Getting Checked to Prevent Cardiovascular Issues." This prompted several readers to inquire about the crucial role of TMG and how they might safely incorporate it into their diets or supplementation routines. In response, I created this concise piece to help inform and empower readers to explore this important nutrient with their healthcare providers.
My First Encounter with TMG
My journey with TMG began in 2005 at a scientific conference, where I met an experimental scientist named Steve. He skillfully combined rigorous scientific research with his experiences as a biohacker, making the complex topic more relatable. His engaging presentation included charts illustrating biomarker data, which made the subject approachable.
Steve discussed various causes of "hyperhomocysteinemia," such as genetic factors, B vitamin deficiencies (including folic acid, B6, and B12), kidney failure, and disruptions in homocysteine metabolism due to medications or metabolic changes, as highlighted in a 2005 publication.
I was pleasantly surprised to discover that Steve, a dedicated scientist, was also a bodybuilder at 53. Our conversation flourished as we shared insights over lunch, particularly about bioavailable protein and healthy fats. Despite my limited knowledge of TMG supplementation, I was eager to learn from his expertise.
Having a background in cognitive science, I had previously examined the effects of betaine on conditions like dementia and depression. Steve generously shared his insights, sparking my curiosity about this fascinating molecule, which our bodies naturally produce. Given its importance, TMG supplements are now widely available without a prescription.
Impressed by Steve’s thorough research, I decided to try a TMG supplement from a reputable U.S. company. The product promised to support healthy homocysteine levels, reduce inflammation for cardiovascular health, maintain healthy blood pressure, and promote mitochondrial function. I supplemented with 1 gram daily, taking a break once a week, and experienced noticeable benefits without side effects.
To my surprise, after six months, my blood markers showed improvement, aligning with findings from a 2021 review that highlighted betaine's substantial therapeutic effects on various health issues.
The pivotal factor here is homocysteine, a topic I previously addressed in my article "Why High Homocysteine Levels Matter and How to Optimize Them." Unfortunately, this health concern is often overlooked, leading to public confusion regarding its significance. A scientific review from 2008 documented that elevated plasma homocysteine correlates with increased mortality rates, stroke incidence, dementia, and other serious health issues.
Building on Steve's insights and my own research, I’ll outline four notable benefits of TMG supplementation for both physical and mental health, emphasizing its role in managing elevated homocysteine levels.
What is Trimethylglycine?
Trimethylglycine, or TMG, is a vital nutrient derived from dietary sources and can also be synthesized from choline in the body through the betaine-homocysteine methyltransferase (BHMT) pathway. This process involves converting choline into betaine via enzymatic reactions, making TMG a crucial methyl donor in our biochemical systems.
TMG plays a significant role in methylation, which is essential for gene expression, protein function, and neurotransmitter synthesis. Its importance is underscored by its abundance in the kidneys and liver, where it serves various functions, including osmoprotection in the kidney and providing methyl groups in the liver's methionine cycle.
Increased interest in betaine is emerging due to its potential in treating conditions such as nonalcoholic fatty liver disease and high homocysteine levels, which heighten cardiovascular risks.
Four Key Benefits of Trimethylglycine
Supporting Healthy Homocysteine Levels and Reducing Cardiovascular Risks
A 2003 study in the Journal of Nutrition concluded that dietary betaine can reduce plasma homocysteine levels, thereby lowering cardiovascular disease risk. A 2021 review in Biology emphasized that TMG helps restore methionine homeostasis, potentially improving cardiovascular health by counteracting inflammatory factors.
Preventing Insulin Resistance and Enhancing Liver Function
Research indicates that increased dietary intake of choline and betaine is linked to lower insulin resistance. A 2017 review in Applied Nutritional Investigation highlighted that higher betaine intake was associated with improved liver health, demonstrating its protective effects against fatty liver and insulin resistance.
Enhancing Fitness Performance
Anecdotal evidence suggests that many athletes use TMG to boost performance. A 2014 review confirmed its potential as an ergogenic aid, although the mechanisms behind its effectiveness remain unclear. Some studies noted significant improvements in strength and power with betaine supplementation.
Improving Mood Disorders, Particularly Mild Depression
Research indicates that combining TMG with other methyl donors like SAMe may enhance mood and alleviate mild depression. A 2015 study suggested that this combination is a safe and effective treatment for individuals recently diagnosed with mild depression.
Conclusions and Recommendations
While anecdotal claims about TMG's effectiveness in fitness are still being evaluated, substantial evidence supports its role in reducing homocysteine levels and mitigating health risks. I personally take TMG daily, experiencing beneficial effects without adverse reactions.
Discovered from sugar beets, trimethylglycine has been acknowledged for its heart-healthy properties since the 1950s. As a metabolite of choline, TMG is an intriguing compound with potential cognitive benefits, as explored in my previous article on choline deficiency.
This discussion focused on the importance of managing homocysteine levels, which are linked to various health issues such as heart disease, stroke, and depression. Given its links to vitamin deficiencies, TMG supplementation can be a valuable strategy for reducing health risks. However, it’s essential to consult healthcare professionals before starting any new supplement, particularly for individuals with existing cardiovascular conditions.
Incorporating foods rich in TMG, such as broccoli, beets, spinach, and shellfish, can naturally boost intake. Blood tests can determine homocysteine levels, and healthcare providers can recommend treatment plans if necessary, especially for those experiencing cardiovascular symptoms.
As discussed in earlier articles, genetic factors like MTHFR polymorphisms can lead to vitamin deficiencies and elevated homocysteine levels, highlighting the importance of genetic screening.
