(2026)"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">If you take NMN, you will quickly come across the advice to add TMG. On forums and longevity podcasts it sounds almost like a rule. But where does that advice come from, how much TMG would you take, and what has actually been studied? This article explains it step by step: no hype, just the biochemistry, the studies and an honest conclusion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Short answer<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Why:<\/strong> NMN is converted into NAD\u207a in the body. When NAD\u207a is used, nicotinamide is released. The body clears part of it through the enzyme NNMT, and that costs methyl groups. TMG (trimethylglycine, also called betaine) is a methyl donor. The idea is that TMG replenishes those methyl groups.<\/li>\n\n\n\n<li><strong>Evidence:<\/strong> the pathway itself is well described. A human study showed that just 100 mg of nicotinamide briefly raises homocysteine and lowers betaine levels. There is no controlled study yet comparing NMN + TMG with NMN alone.<\/li>\n\n\n\n<li><strong>Dosage:<\/strong> there is no scientifically established ratio. A common, cautious practice is roughly the same to twice as much TMG as NMN, for example 250\u2013500 mg NMN with 500\u20131,000 mg TMG per day.<\/li>\n\n\n\n<li><strong>Safety:<\/strong> TMG at these amounts is well tolerated. At higher doses (from about 4 grams per day) LDL cholesterol may rise slightly.<\/li>\n\n\n\n<li><strong>Conclusion:<\/strong> combining NMN with TMG is biochemically logical and low-threshold, but not a proven must. It is a precautionary choice, not a miracle combination.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What are NMN and TMG again?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>NMN (nicotinamide mononucleotide)<\/strong> is a direct precursor of NAD\u207a, a coenzyme involved in energy processes in every cell and in enzymes such as sirtuins and PARPs. NAD\u207a levels decline with age, which is why NMN gets so much attention in longevity. Read more in <a href=\"https:\/\/everydaybetter.nl\/en\/supplements-for-healthy-aging\/nmn\/how-does-nmn-work\/\">How does NMN work?<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>TMG (trimethylglycine)<\/strong> is known in the scientific literature as betaine. It occurs naturally in beets, spinach and whole grains. TMG carries three methyl groups and can donate one in the so-called BHMT pathway, which converts homocysteine into methionine. More background on <a href=\"https:\/\/everydaybetter.nl\/en\/supplements-for-healthy-aging\/tmg\/\">What is TMG?<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why take TMG with NMN? The NNMT pathway explained<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The reason to take TMG with NMN comes down to one enzyme: <strong>NNMT (nicotinamide N-methyltransferase)<\/strong>. This is how the pathway works:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>NMN is converted into NAD\u207a in the body.<\/li>\n\n\n\n<li>Enzymes that use NAD\u207a (sirtuins, PARPs, CD38) break it down, releasing <strong>nicotinamide<\/strong>.<\/li>\n\n\n\n<li>Part of that nicotinamide is recycled to make new NAD\u207a. Another part is cleared via NNMT.<\/li>\n\n\n\n<li>NNMT attaches a methyl group to nicotinamide. That methyl group comes from <strong>SAMe<\/strong>, the body&#8217;s main methyl donor. This produces 1-methylnicotinamide (1-MNA), which is later excreted in urine.<\/li>\n\n\n\n<li>What remains of SAMe becomes <strong>homocysteine<\/strong>.<\/li>\n\n\n\n<li>Homocysteine is converted back into methionine, either via folate and vitamin B12, or via the BHMT pathway with <strong>betaine (TMG)<\/strong> as the methyl donor.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-1200x675.jpg\" alt=\"Diagram of why NMN and TMG complement each other: NMN is converted into NAD+, and TMG provides methyl groups for methylation\" class=\"wp-image-14731\" srcset=\"https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-1200x675.jpg 1200w, https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-600x338.jpg 600w, https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-768x432.jpg 768w, https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-1536x864.jpg 1536w, https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other-900x506.jpg 900w, https:\/\/everydaybetter.nl\/wp-content\/uploads\/2026\/10\/diagram-1-why-nmn-and-tmg-complement-each-other.jpg 1600w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Diagram of why NMN and TMG complement each other: NMN is converted into NAD+, and TMG provides methyl groups for methylation<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In short: the more nicotinamide the body has to clear via NNMT, the more methyl groups it costs. TMG can help top up that supply. That is the logic behind the combination.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does the research say?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The biochemical pathway is well described. Direct evidence for the NMN + TMG combination in humans does not exist yet. This is where things stand:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Study<\/th><th>What was studied<\/th><th>What it shows<\/th><\/tr><\/thead><tbody><tr><td><a href=\"https:\/\/www.nature.com\/articles\/hr2011151\" target=\"_blank\" rel=\"noopener\">Sun et al., 2012, Hypertension Research<\/a><\/td><td>Single 100 mg dose of nicotinamide in 46 adults, blood after 5 hours<\/td><td>1-MNA rose sharply, homocysteine rose (significantly in people with normal blood pressure), betaine fell<\/td><\/tr><tr><td>Olthof et al., 2003<\/td><td>1.5, 3 and 6 g betaine per day, 6 weeks<\/td><td>Fasting homocysteine 12%, 15% and 20% lower than placebo<\/td><\/tr><tr><td>McRae, 2013 (meta-analysis)<\/td><td>5 RCTs, \u2265 4 g betaine per day<\/td><td>Homocysteine on average 1.23 \u00b5mol\/L lower<\/td><\/tr><tr><td>Zawieja et al., 2021 (meta-analysis)<\/td><td>Betaine supplementation<\/td><td>Total and LDL cholesterol may rise slightly, mainly at high doses<\/td><\/tr><tr><td><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12467181\" target=\"_blank\" rel=\"noopener\">Jawaria et al., 2025, Biomolecules<\/a><\/td><td>Review on NNMT<\/td><td>NNMT consumes SAMe and produces homocysteine; mainly preclinical data<\/td><\/tr><tr><td>NMN + TMG together<\/td><td>\u2014<\/td><td>No controlled human study found that tests the combination<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The study by Sun and colleagues is the most interesting piece of the puzzle. They used nicotinamide, not NMN. Still, it shows that a form of vitamin B3 engages the methylation system within hours and uses up betaine. Whether that matters at common NMN doses in the long term has not been studied.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How much TMG should you take with NMN?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is <strong>no scientifically established ratio<\/strong> between NMN and TMG. What you see online, such as a 1:1 or 1:2 ratio, is a rule of thumb, not a research finding. There are, however, some reference points:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Reference point<\/th><th>Amount<\/th><th>Source<\/th><\/tr><\/thead><tbody><tr><td>Common practice<\/td><td>TMG roughly equal to or double your NMN dose<\/td><td>Practical rule of thumb, not studied<\/td><\/tr><tr><td>Using the bundle<\/td><td>1\u20132 NMN capsules (250\u2013500 mg) + 1\u20132 TMG capsules (500\u20131,000 mg) per day<\/td><td>Every Day Better label<\/td><\/tr><tr><td>EU health claim for betaine<\/td><td>1.5 g per day contributes to normal homocysteine metabolism<\/td><td>EU register of health claims<\/td><\/tr><tr><td>Doses studied<\/td><td>1.5\u20136 g betaine per day<\/td><td>Olthof 2003, McRae 2013<\/td><\/tr><tr><td>Watch out<\/td><td>From about 4 g per day LDL cholesterol may rise slightly<\/td><td>Zawieja 2021<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For most people taking 250\u2013500 mg of NMN, 500\u20131,000 mg of TMG is a logical, cautious choice. That is well below the doses at which effects on cholesterol were seen.

A baseline and a follow-up after a few months tell you more than any rule of thumb.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Side effects and safety of NMN with TMG<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In studies of healthy adults, NMN was well tolerated at up to about 1,250 mg per day for several weeks. TMG at doses up to a few grams per day rarely causes complaints; occasionally these are digestive upset, nausea or headache. The main point of attention with TMG is the slight rise in LDL cholesterol at higher doses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do you take medication, are you pregnant or breastfeeding, or do you have a medical condition?

It is a precaution: NMN can cost methyl groups via NNMT and TMG can replenish them. No study has yet shown that the combination works better than NMN alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How much TMG should you take with 250 mg of NMN?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A common, cautious choice is 250\u2013500 mg of TMG. With 500 mg of NMN, 500\u20131,000 mg of TMG makes sense. There is no fixed, studied ratio.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is NNMT and why does it matter for NMN?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">NNMT (nicotinamide N-methyltransferase) is an enzyme that clears excess nicotinamide by attaching a methyl group to it. That methyl group comes from SAMe. As a result, a lot of nicotinamide can put a load on the methylation system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does NMN raise homocysteine?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This has barely been studied for NMN itself. A study with 100 mg of nicotinamide showed a short-term rise in homocysteine. If you want certainty, have your homocysteine measured.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is TMG the same as betaine?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. TMG (trimethylglycine) and betaine (betaine anhydrous) are the same substance. Betaine HCl is a different form, mainly used as a stomach acid supplement. See <a href=\"https:\/\/everydaybetter.nl\/en\/supplements-for-healthy-aging\/tmg\/tmg-vs-betaine\/\">TMG vs betaine<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When should you take NMN and TMG?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most people take both in the morning, with or after breakfast. Taking them consistently matters more than the exact moment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does NMN with TMG have side effects?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At common doses both are usually well tolerated. TMG can occasionally cause digestive upset and, at high doses (from about 4 g per day), slightly raise LDL cholesterol.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can you get TMG from food?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Beets, spinach, quinoa and whole wheat contain betaine. Your body also makes it from choline, found in eggs among other foods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Combining NMN with TMG is biochemically logical: the breakdown of NAD\u207a releases nicotinamide, and clearing it via NNMT costs methyl groups that TMG can replenish. Direct evidence that the combination works better than NMN alone is still missing. For anyone taking NMN daily, a modest dose of TMG (roughly equal to or twice the NMN dose) is a low-threshold precautionary choice. Do not expect miracles, and measure your homocysteine if you want to be sure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sources<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sun W-P et al. (2012).
