If you are curious about improving your health and supporting your body's natural processes, TMG supplements might have caught your attention.
For trimethylglycine, TMG is a naturally occurring compound often linked to better cellular function, methylation support, and even improved mood.
But what is it, and why are so many people talking about it?
This article covers everything you need to know about TMG supplements—their benefits, how to use them, and safety considerations.
Whether you are exploring new ways to boost your wellness routine or want to learn the facts, we have you covered.
What Are TMG Supplements?
TMG supplements, short for trimethylglycine, are dietary supplements derived from a naturally occurring compound in foods like beets, spinach, and quinoa. They are commonly used to support methylation, a process critical for DNA repair, energy production, and liver health.
Some studies suggest that TMG plays a role in maintaining heart health by helping to regulate homocysteine levels, a marker linked to cardiovascular risk (1).
Trimethylglycine works by donating methyl groups, which are essential for several biochemical processes in the body. This function has drawn research interest, particularly its potential to support liver function and reduce elevated homocysteine levels.
If you are considering TMG supplements, starting with small doses and consulting a healthcare professional is an excellent approach to ensure they align with your health needs.
How Does Trimethylglycine (TMG) Function in the Body?
Trimethylglycine (TMG) serves as a methyl donor, playing a vital role in DNA repair, energy production, and the breakdown of homocysteine—an amino acid linked to cardiovascular risks when elevated.
Through methylation, TMG converts homocysteine into methionine, potentially supporting heart health by lowering homocysteine levels. Individual outcomes may vary based on genetics and nutrient status (2, 3).
TMG also aids liver function by supporting fat metabolism and detoxification, with studies suggesting it may protect liver cells from oxidative stress (4).
While found in foods like beets and spinach, supplementation provides targeted benefits.

Top Potential Health Benefits of TMG Supplements
TMG supplements have gained attention for their potential to support various aspects of health, from heart function to cellular energy. While research is ongoing, several benefits are worth exploring based on current studies and insights.
May Lower Homocysteine Levels for Better Heart Health
TMG supplements might be beneficial for heart health, particularly in managing homocysteine levels. High homocysteine has been linked to an increased risk of heart disease, and some research suggests TMG could help by converting it into methionine, another compound your body uses.
For example, a study found that taking up to 4 grams of TMG daily reduced homocysteine levels without affecting other markers like blood pressure or triglycerides (5).
However, other studies have shown that TMG might slightly increase total and LDL (bad) cholesterol, which are also risk factors for heart disease (6).
While TMG shows promise, there is still more to learn about its overall impact on heart health. If you are considering supplements, discussing them with your doctor is always best.
Could Help Boost Athletic Performance
TMG supplements are gaining attention because of their potential to support athletic performance.
A study involving 29 soccer players showed promising results. Participants who took 2 grams of TMG daily for 14 weeks experienced improvements in muscle strength, sprint speed, and overall performance (7).
While the exact reasons behind these benefits are not fully understood, researchers believe TMG might help by reducing fatigue and supporting energy production in muscles (8).
That said, research is still mixed, and more studies are needed to confirm these findings.
May Support Insulin Sensitivity
TMG supplements might help improve insulin resistance, a condition where the body struggles to manage blood sugar effectively (9).
A 2017 study involving nearly 2,400 people found that higher intakes of choline and betaine (a compound related to TMG) were linked to lower levels of insulin resistance (10).
Could Help Alleviate Depression Symptoms
TMG supplements might play a role in easing depression, especially when paired with certain treatments.
A study with 64 participants found that combining TMG with S-adenosyl-methionine (SAMe), a common treatment for mild to moderate depression, improved symptoms more than using SAMe alone over 12 months (11).
This connection might be due to TMG’s ability to lower homocysteine levels, which are sometimes linked to depression and anxiety (12).
Are There Any Side Effects of TMG Supplementation?
When recommended, TMG supplementation is generally considered safe for most people, but some individuals may experience mild side effects such as:
Diarrhea: Loose stools are common, especially at higher doses.
Indigestion: A burning or discomfort in the upper abdomen may occur.
Bloating: Excess gas can lead to a swollen or tight feeling in the stomach.
Cramps: Some people experience stomach or intestinal spasms.
Nausea: A queasy feeling is another potential side effect.
Vomiting: Rarely, some individuals may vomit after taking TMG.
In very rare cases, TMG could increase methionine levels in the blood, potentially causing fluid build-up around the brain (13). If you experience any of these side effects, stop using TMG and consult a doctor.
Due to limited safety research, TMG is not recommended for children, pregnant women, or those nursing. Another point to consider is that high doses of TMG could occasionally lead to increased heart rate or restlessness in sensitive individuals, although this is rare.
Monitoring how your body responds to supplementation and adjusting if needed is always a good idea.
If you are pregnant, breastfeeding, or managing specific health conditions, it is best to consult with a healthcare provider before starting TMG.
While the supplement has shown promise in several areas, personalized advice ensures its use aligns with your unique health needs.
Who Should Consider Taking TMG Supplements?
TMG supplements may be a good option for individuals looking to support methylation, heart health, or overall cellular function. However, before starting any supplement, discussing your goals and current health status with a healthcare provider is always a good idea to ensure it is the right fit for you.
People with elevated homocysteine levels: TMG can support the conversion of homocysteine into methionine, which may help maintain heart health when paired with adequate B vitamins.
For those seeking liver support, its role in promoting fat metabolism and assisting in detoxification makes TMG worth considering for liver health.
Individuals with low energy or fatigue: TMG contributes to methylation, a process essential for energy production at the cellular level.
Athletes and active individuals: Some research suggests TMG may improve endurance and recovery due to its potential effects on cellular hydration and energy (14).
People exploring mood support: TMG could benefit mood balance by aiding neurotransmitter synthesis through methylation (15).
Dosage of TMG Supplements
TMG supplements have no set dosage, but most products offer between 750 and 3,000 milligrams (mg) per serving.
Studies show it is generally safe to take up to 20 grams a day (16), though most research in humans has used doses ranging from 500 to 9,000 mg daily, often split into smaller doses throughout the day (17).
If you have any health conditions or take medications, it is important to talk to your doctor before starting TMG. Always stick to the directions provided with the supplement.
How to Choose a High-Quality TMG Supplement?
Choosing a high-quality TMG supplement involves looking at a few key factors to ensure safety and effectiveness. For instance:
Purity and Ingredient Quality
