TMG (Trimethylglycine) and glycine are amino acids with distinct properties and health benefits. TMG is an amino acid commonly found in beets and leafy greens, while glycine can be found in dairy products and plant-based sources like beans and mushrooms. TMG is believed to enhance protein production, limit fatigue, and boost creatine synthesis, offering potential benefits for athletic performance and recovery. It also supports heart health by lowering homocysteine levels and may provide anti-inflammatory and antioxidative effects. However, TMG may cause side effects, including disturbed sleep, gastrointestinal issues, and increased cholesterol levels. On the other hand, glycine is known for its relaxing properties and is often taken to promote better sleep. It also helps to protect the mitochondria and has anti-inflammatory and positive metabolic effects. The decision to take TMG or glycine depends on individual needs and preferences, and it is always advisable to consult with a healthcare professional before starting any supplement regimen.

What You'll Learn

TMG and glycine are amino acids
Glycine is often taken to help with sleep and relaxation. It buffers excess methylation. Many people take glycine with NMN at night to help them relax and sleep. It can also help protect the epigenome, especially in mitochondria, and has anti-inflammatory and various positive metabolic effects. It also extends the lifespan in different species.
TMG, on the other hand, is more energizing and is usually taken in the morning. It donates methyl groups to support methylation. Research suggests that TMG may contain anti-inflammatory properties. It also supports gene expression and cellular health. TMG may also assist in the production of S-adenosylmethionine (SAMe), which protects cells against oxidative stress and DNA damage.
TMG and glycine are not antagonistic towards each other, and some people take both supplements. However, in some patients, TMG can cause side effects, especially in the long term, such as disturbed sleep or gastrointestinal issues. Therefore, it is always best to consult a healthcare professional before taking any supplements.

TMG is energising, glycine is relaxing
TMG, or Trimethylglycine, is an amino acid commonly found in beets and leafy greens. It is a compound produced in the human body that supports DNA function and heart health. TMG is an essential supplement for those with a mutation in the MTHFR gene and high homocysteine levels. It converts the inflammatory amino acid homocysteine into methionine, which is much safer and better for you. TMG also has anti-inflammatory and antioxidative properties, and may enhance protein production, limit fatigue, and boost creatine synthesis. Research shows that TMG supplementation can improve S-adenosylmethionine (SAMe) production in the body, which may improve sleep quality. However, some people have reported disturbed sleep as a side effect of TMG. TMG is energising and is best taken in the morning.
Glycine, on the other hand, is an amino acid that helps to protect the epigenome, especially in mitochondria. It also has anti-inflammatory and positive metabolic effects. Glycine buffers excess methylation, while TMG donates methyl groups to support methylation. Glycine is more relaxing and is best taken at night to help with sleep and relaxation.
TMG and glycine are not antagonistic towards each other, and some people take both supplements. However, it is important to do your own research and consult a healthcare professional before taking any new supplements, especially if you have a medical condition.

TMG may improve heart health
TMG, or Trimethylglycine, is a compound produced in the body that supports DNA function and methylation. Methylation is a chemical process that is essential for DNA production. TMG is also available from food and supplement sources.
Some studies have linked TMG supplements with increases in both LDL and total cholesterol levels, which could increase the risk of heart disease. However, other studies have found that taking up to 4 grams of TMG per day helped lower homocysteine levels without negatively impacting other aspects of heart health, such as blood pressure and triglyceride levels.
TMG also protects cells against oxidative stress and DNA damage, which may further contribute to its beneficial effects on heart health.

Glycine may protect against cancer
While TMG can help improve sleep quality, glycine is more relaxing and is often taken at night to promote sleep. Both TMG and glycine are amino acids, but they have distinct effects on the body. TMG is energizing and is recommended for morning consumption. It is also an anti-inflammatory and antioxidative compound that can be beneficial for heart health, athletic performance, insulin regulation, and mental well-being.
Now, here are four to six paragraphs on "Glycine May Protect Against Cancer":
Glycine, a non-toxic amino acid, has been found to exhibit anti-tumorigenic properties in various cancers. Specifically, dietary glycine has been shown to decrease tumor volume and vascularization in a colorectal liver metastasis and chemotherapy model. This suggests that glycine may be an attractive anti-cancer agent, particularly in combination with chemotherapy.
In vivo studies have demonstrated that glycine protects against chemotherapy-induced liver injury, making it a potential therapeutic option for colorectal cancer liver metastases (CRLM). However, there is a lack of in vivo data to confirm the direct anti-cancer effects of glycine on CRLM. While glycine has shown promising results in cancer treatment, there is also conflicting evidence regarding its role in cancer cell metabolism and proliferation.
Some studies indicate that glycine is essential for cancer cells, as it provides precursors for macromolecules and antioxidant defense. Upregulating serine and glycine biosynthesis may be a potential therapeutic target. Additionally, restricting dietary serine and glycine has been found to reduce CRC tumor growth in mouse models. However, other studies suggest that depleting the glycine cleavage system or restricting exogenous glycine does not impede cancer cell proliferation.
While the exact role of glycine in cancer is still under investigation, it is clear that it plays a crucial part in cancer cell metabolism. Further research is needed to fully understand the complex nature of glycine's interaction with cancer cells and to develop effective anti-cancer therapies targeting glycine metabolism.

Consult a doctor before taking either
TMG (Trimethylglycine) and glycine are both amino acids. While TMG is energizing and best taken in the morning, glycine is more relaxing and better suited for nighttime. Some people take glycine with NMN at night to help them relax and sleep.
TMG is believed to enhance protein production, limit fatigue, and boost creatine synthesis, thereby improving athletic performance and recovery. It also supports heart health by lowering homocysteine levels, which is a key player in heart disease. TMG may also improve insulin resistance and promote liver function.
Glycine, on the other hand, can selectively buffer excess methylation, while also providing anti-inflammatory and positive metabolic effects. It can help protect the mitochondria and may decrease cancer rates.
However, before taking either supplement, it is important to consult a doctor or healthcare professional. TMG may cause side effects, especially in high doses, such as digestive issues, low mood, or confusion. It may also interact with medications or conditions affecting methylation, and its effect on cholesterol requires caution. Trimethylglycine is not recommended for children, pregnant, or breastfeeding women without medical advice.
Similarly, while glycine is generally considered safe, it is always advisable to consult a healthcare provider to ensure it does not interfere with any existing medical conditions or medications. Additionally, they can advise on the appropriate dosage and timing for your specific needs. Consulting a doctor is especially important if you intend to take both supplements, as combining them may have different effects than taking them individually.
