Interactions: There are no known published interactions between TMG and other medications at 10 November 2024. However, this does not mean interactions do not exist. TMG is used to lower levels of Homocysteine and may interfere with other similar medications. If you are taking these medications or any other medication, please first speak with your doctor before adding TMG to your supplement regime.

For further information regarding any other potential drug and supplement interactions with TMG, please see the individual ingredient profiles on Drug Bank using the link below.* Allergy: This product does not contain any common allergens; however, it should not be used by anyone with a history of hypersensitivity to its ingredients or those taking medications that may interact with it.

Key Studies to Consider

While individual results may vary due to personal health conditions, genetics, and lifestyle choices, we guarantee that the supplements you receive are made with ingredients of the highest purity, similar to those used in scientific studies, to ensure maximum results.

Methylation

TMG (also known as betaine) supplies the body with methyl groups during methylation, supporting processes like DNA repair, gene regulation, and detoxification by converting homocysteine to methionine in the methylation cycle.

Heart Health

Low dose betaine supplementation leads to immediate and long term lowering of plasma homocysteine in healthy men and women – Randomised Controlled Trial

Dosage: Daily doses of 1.5, 3, and 6 grams of betaine for 6 weeks

Outcome: Reduced levels of plasma homocysteine, which is associated with lower risk of heart disease

Summary: Taking betaine was found to significantly lower the levels of homocysteine in the blood both immediately and over six weeks in healthy adults. This suggests that eating foods high in betaine or taking supplements could help reduce the risk of heart disease.

 Betaine supplementation decreases plasma homocysteine in healthy adult participants: a meta-analysis – Meta-analysis

Intervention: At least 4 g/day of betaine for 6 to 24 weeks

Outcome: Reduction in plasma homocysteine levels by 1.23 μmol/L

Summary: Betaine supplementation at a dose of at least 4g/day for a minimum of 6 weeks significantly lowers plasma homocysteine levels in healthy adults, which could contribute to heart protection.

Performance

Effects of betaine on body composition, performance, and homocysteine thiolactone –  Randomised Controlled Trial

Dosage: 2.5 grams of betaine daily for 6 weeks

Outcome: Changes in body composition, arm size, bench press performance, and a marker in the urine related to heart health

Summary: Betaine supplementation for 6 weeks helped improve body composition and arm size, increased bench press performance, and reduced a potentially harmful marker in the urine without significantly enhancing overall strength or power in experienced strength-trained men.

Effects of chronic betaine supplementation on performance in professional young soccer players during a competitive season – Randomised Controlled Trial

Dosage: 2 grams of betaine (also known as TMG) daily for 14 weeks

Outcome: Improvement in muscle strength, oxygen use during exercise, and ability to perform repeated sprints

Summary: Giving young professional soccer players betaine every day for 14 weeks helped them get stronger, use oxygen better during exercise, and do repeated sprints more effectively compared to those who didn’t take betaine.

Effects of Short-Term Betaine Supplementation on Muscle Endurance and Hormone Levels After Intense Exercise in Young Athletes – Double-Blind, Crossover Study

Dosage: 2.5 grams of betaine daily for 14 days

Outcome: Increased muscle endurance, lower stress hormone levels, and higher testosterone levels after intense exercise

Summary: Young handball players who took betaine for two weeks could do more repetitions in exercises and had better hormone levels indicating less stress and better muscle recovery compared to when they took a placebo.

Everything You Need To Know About TMG

Trimethylglycine (TMG), also known as betaine, is a derivative of the amino acid glycine. It is found naturally in the body and in certain foods, such as beetroot, spinach, and whole grains. TMG supports methylation, a biochemical process essential for cellular function and adaptation to the body’s changing demands.

TMG supports methylation by converting excess homocysteine into methionine. Through this process, TMG attaches a methyl group to homocysteine, forming methionine, which is then used to produce S-adenosylmethionine (SAMe), a key methyl donor which supports methylation by ensuring there are enough “methyl groups” to meet the body’s methylation demands.

Methylation modifies DNA by adding methyl groups to specific molecules in the body, turning certain genes on or off, and ensuring essential functions like repair and growth are active while silencing unnecessary processes for cell stability. In detoxification, methylation transforms toxins into safer, water-soluble compounds that the liver can then expel from the body. For neurotransmitter production, SAMe donates methyl groups to create serotonin and dopamine building blocks, thereby aiding in their formation. Additionally, by donating methyl groups to creatine precursors, methylation helps to increase creatine availability, supporting energy demands during high-intensity exercise.

Long-term NMN or NR use can deplete methyl groups because excess nicotinamide produced in the NMN-to-NAD cycle requires methylation for removal. This depletion might lead to fatigue in some individuals. TMG can help replenish these methyl groups, though it’s not necessary for everyone. If you experience fatigue with NMN or NR, it is recommended that you consider supplementing with TMG.

Healthy methylation supports essential bodily functions by adding or removing chemical groups (methyl groups) to activate or silence genes as needed. This is required for cell growth, repair, and the regulation of cellular functions. In a simple sense, methyl groups can be considered the fuel for methylation.

It is estimated that up to 70% of the population has a variant in the MTHFR gene, known as a polymorphism. The majority of these variants can lead to reduced methylation as they affect an enzyme essential for producing SAMe – the body’s primary methyl donor. Consult a healthcare professional if you have concerns about your MTHFR status.

Research suggests that methylation capacity declines with age, leading to impaired cellular function, inefficient detoxification, and increased homocysteine levels, all of which are linked to age-related decline. Supporting optimal methylation activity and keeping homocysteine levels within a healthy range may help support long-term cellular health.

Consider the statements below. If you find one or more relatable, TMG might be the supplement you’re looking for:

  • I wish to support a healthy cardiovascular system by managing homocysteine levels.
  • I take NAD precursors and fatigue is a constant battle for me. I seek to improve my energy levels for a more active lifestyle.
  • My healthcare provider mentioned the importance of supporting methylation processes for overall health.
  • I’m interested in supporting a healthy mood balance and I feel my methylation status is having an impact.
  • I have a reduction in MTHFR activity and wish to support healthy methylation.

Frequently Asked Questions

This TMG supplement is Betaine Anhydrous and will not raise stomach acid.

Yes, TMG is made in the body.

TMG is naturally found in foods such as beets, broccoli, shellfish, and spinach. However, due to the low amounts present in food, a supplement is likely the best option to receive the full benefits of TMG.

TMG supports methylation in the body. For some, TMG supplementation can lead to excess methylation, which can result in symptoms such as anxiety and fatigue. If you experience any of these symptoms, it is recommended that you stop taking TMG.
