If you’ve ever looked into supplements that support methylation, you’ve likely come across the TMG supplement, also known as trimethylglycine or betaine anhydrous. This naturally occurring compound plays a quiet but crucial role in how your body produces energy, regulates homocysteine levels, and protects your liver.
Our TMG Supplement at Longevity Box is formulated with pure, third-party-tested trimethylglycine (750 mg) per capsule, free from fillers, binders, or additives. It’s a simple, science-backed way to support your body’s natural methylation and detoxification processes daily.
Research shows that TMG may lower homocysteine, an amino acid linked with heart disease when elevated, and support overall liver health and energy metabolism. Studies also suggest TMG can enhance performance by supporting creatine production and methyl balance, especially in those using NAD+ precursors such as NMN or NR.
Let’s explore what TMG is, how it works, and why it’s considered one of the most valuable tools for supporting heart and liver health, vitality, and longevity.
What Is TMG (Trimethylglycine)?
TMG (trimethylglycine) is a natural compound first isolated from sugar beet juice in the 19th century, which is why it’s often simply called betaine. You’ll find TMG in food such as spinach, wheat bran, quinoa, and beets, though cooking can significantly decrease the TMG content.
Biochemically, TMG is also known as betaine anhydrous. It’s made up of the amino acid glycine bound to three methyl groups, and these methyl groups are what make it so vital to your body. They act as “methyl donors,” helping to transfer methyl units in reactions that regulate DNA production, detoxification, and neurotransmitter synthesis.
This methylation process is also how TMG may help protect your cardiovascular system. It supports the conversion of homocysteine (an amino acid that can damage blood vessels when too high) into methionine, a safer, beneficial compound. By maintaining healthy homocysteine levels, TMG supplementation can improve methylation efficiency throughout the body.
In practical terms, this means TMG may play a role in protecting your heart, improving energy metabolism, and supporting liver detoxification.
At Longevity Box, we use only high-purity TMG (Trimethylglycine), tested at 99% purity, to ensure you get the most effective and reliable supplement to support your body’s methylation pathways.
Key Benefits of TMG Supplementation
One of the most researched benefits of TMG is its ability to support heart health through homocysteine management. Elevated or high homocysteine levels can strain the cardiovascular system and are considered a key risk factor for heart disease.
The role of TMG here is simple yet profound; it donates a methyl group to convert homocysteine into methionine, helping maintain healthy homocysteine levels in the blood.
A 2021 review found that taking up to 4 grams of TMG per day helped to lower homocysteine levels without negatively impacting other markers of cardiovascular health, such as blood pressure or triglycerides. However, the same review noted that research shows that TMG might slightly increase LDL (bad) cholesterol in some individuals, so balance and moderation are key.
In short, maintaining the right dosage of TMG, like the 750 mg per capsule found in the Longevity Box TMG supplement, offers the potential to support cardiovascular wellness without the adverse effects linked to excessive intake.
Promoting Liver Function and Detoxification
Another major reason to take TMG supplements is to support liver health and detoxification. The liver relies heavily on methylation to process toxins and maintain metabolic balance, and TMG is a critical part of that cycle.
Betaine supplementation has shown promising effects on reducing fatty liver and improving enzyme balance. A 2021 study published in Biology reported that betaine protects against both alcohol-induced and non-alcoholic liver disease, likely through its impact on homocysteine concentrations in healthy humans and its ability to restore SAMe (S-adenosylmethionine) production, a compound essential for liver detoxification.
These findings suggest TMG may protect the liver from oxidative stress and improve detox pathways, particularly in those with high levels of homocysteine or reduced methylation capacity.
At Longevity Box, our TMG supplement offers an easy way to support these natural detox processes. Taken daily, it provides steady methylation support and peace of mind, with every capsule independently verified for purity and potency.
The Potential Benefits of Taking TMG Supplements
Beyond its influence on methylation, TMG supplementation may provide wider health benefits that extend to energy, cognition, and metabolic balance. It’s a naturally occurring compound your body can produce in small amounts of TMG, yet supplementation supports levels that are often reduced by ageing, diet, or stress.
Several studies have found that TMG can influence multiple pathways in the body. It contributes methyl groups needed for energy metabolism and the creation of neurotransmitters like dopamine and serotonin, both essential for a stable mood and focus.
Let’s look at the potential benefits of maintaining optimal TMG levels:
-
Improved energy and endurance: Research suggests that TMG may help boost muscle strength and recovery by supporting creatine synthesis. One clinical study found that TMG enhanced sprint capacity and muscular strength in trained athletes, highlighting its role in sustaining physical performance.
-
Better insulin sensitivity: In studies linking choline and betaine intake to metabolic health, TMG may affect insulin resistance, helping regulate glucose metabolism in people with reduced insulin sensitivity.
-
Cognitive and mood support: Some evidence shows that TMG may also help balance neurotransmitter production, which can contribute to improved focus and reduced symptoms of mild low mood.
-
Cellular protection: As an antioxidant methyl donor, TMG could help defend cells from oxidative stress, supporting DNA integrity and cellular repair.
While human trials continue, the effects of TMG appear to support both mental and physical well-being. This makes it an excellent supplement to support long-term vitality, especially when used consistently as part of a healthy lifestyle.
Comparing the Beneficial Effects of Betaine and TMG
You might have noticed that TMG is also known as betaine or betaine anhydrous, and while these names refer to the same compound, they’re often used in different contexts. Understanding the beneficial effects of betaine alongside TMG supplementation can help you choose the right product and dose for your needs.
Comparing Trimethylglycine (TMG) and Betaine Anhydrous
Both versions contribute to methylation by donating a methyl group, transforming high homocysteine levels into methionine and keeping homocysteine levels in the blood within a healthy range.
Research shows that TMG supplementation can improve muscle endurance, whereas the effects of betaine supplementation may relate more to fluid balance and resilience under physical stress. However, the effects of chronic betaine supplementation are still being studied, particularly in endurance athletes and older adults.
In practical terms, whether you use TMG or betaine supplementation, the goal remains the same: to support methylation and maintain healthy homocysteine levels. The difference lies mostly in purity and purpose. Longevity Box’s TMG supplement focuses purely on methylation, detoxification, and cellular repair without unnecessary additives, ideal for those seeking a cleaner, clinical-grade option.
Possible Side Effects and Considerations
TMG supplements are not recommended for children, pregnant, or breastfeeding women, as research into their safety and long-term effects is still limited. For most healthy adults, however, TMG is well tolerated when used as directed.
Here’s a quick breakdown of key points to keep in mind:
-
Mild digestive discomfort: Some side effects may occur at high doses of TMG (above 3–4 grams daily). These can include bloating, nausea, diarrhoea, or cramps. They usually resolve by lowering the amount of TMG taken or taking it with food.
-
Cholesterol changes: Certain studies have found that TMG may slightly raise total and LDL cholesterol, though evidence is mixed. Speak to your healthcare provider if you already have high cholesterol to understand how TMG may affect your lipid levels.
-
Elevated methionine levels: In rare cases, excessive intake of this supplement has been linked to increased methionine, which may cause fluid build-up around the brain. This highlights the importance of moderate and consistent TMG supplementation.
-
Seek medical advice: If you experience any side effects, stop using it and consult a clinician.
At the recommended Longevity Box dosage (750 mg daily), TMG offers a safe, evidence-backed way to support methylation, heart health, and detoxification naturally, without unnecessary risk.
Forms of TMG Supplements Available
You can find TMG (trimethylglycine) in several supplement forms, each with its own benefits and level of convenience. The key is choosing a form that matches your lifestyle and purity expectations.
While TMG is also present naturally in foods like spinach and beets, the levels of TMG in these sources can vary widely. Cooking methods such as boiling can significantly decrease the TMG content, so dietary intake alone rarely provides a meaningful dose. That’s why many people take TMG supplements to achieve consistent, measurable benefits.
Here are the most common forms of TMG you’ll find on the market today:
-
Pure TMG capsules – The most convenient and accurate option. Each capsule delivers a consistent dosage of TMG, ideal for maintaining healthy homocysteine levels. The Longevity Box TMG supplement offers 750 mg per capsule, 99% pure, and third-party tested, without fillers or additives.
-
TMG powder – Allows flexible dosing but can be harder to measure precisely. It may also have a slightly bitter taste, which some people find unpleasant.
-
TMG blends – Combined with nutrients like folate, vitamin B12, or SAMe for enhanced methylation. These may benefit those with specific methylation challenges but can complicate dosage tracking.
Whichever form you choose, quality matters most. Independent testing confirms that Longevity Box’s TMG supplement provides the purest betaine anhydrous available, a clean, vegan, and gluten-free supplement to support daily methylation, liver health, and energy production.
