Most NMN users have never heard of this. But should.
Converting NMN into usable cellular energy is a methylation dependent process. TMG is the methyl donor that keeps that process running efficiently. Here is why advanced users pair them together.
If you have been taking NMN for a while, you already know the basics: it supports NAD+ levels, cellular energy, and DNA repair. But there is a piece of the puzzle most people miss.
The conversion of NMN into usable NAD+ is a methylation dependent process. That means your body draws on its supply of methyl groups along the way. Over time, especially as you age, this demand can outpace supply. The result? Your NMN may not be working as efficiently as it could. TMG (trimethylglycine) is a methyl donor that helps replenish that supply, supporting the very process your NMN relies on.

NMN uses methyl groups
When your body converts NMN into NAD+, it draws on methyl groups. These are molecular building blocks required for DNA methylation, neurotransmitter synthesis, and cellular detoxification. High dose NMN use can increase demand on this supply.
TMG replenishes the supply
TMG (trimethylglycine) is one of the body's most important methyl donors. It feeds into the SAMe cycle, the body's main system for distributing methyl groups where they are needed. It also converts homocysteine back into methionine, supporting cardiovascular health.
Together they complete the loop
NMN supports NAD+ and cellular energy. TMG supports the methylation processes that NMN depends on. Together they support the full arc of the NAD+ pathway, from production to the methylation it relies on to keep running.
Most supplements lose the majority before they reach your cells
Both NMN and TMG face absorption challenges with standard capsules. Stomach acid and digestive enzymes break down active ingredients before they reach the bloodstream. Our liposomal encapsulation technology wraps each molecule in a phospholipid shell to protect it through digestion and deliver far more to your cells.
~10% absorbed
Broken down in digestion. Most of the active ingredient never reaches the cell.
Up to 95% absorbed
A phospholipid shell protects the compound through digestion so far more reaches your cells intact.
More of what you pay for actually reaches your cells
Both our NMN and TMG are encapsulated in microscopic phospholipid spheres, the same type of fat based layer that surrounds every cell in your body. These liposomes shield the active ingredients from digestive breakdown, transport them into the bloodstream intact, and then fuse with cellular membranes to deliver the compounds directly inside the cell.
The result is more efficient methylation support, helping optimize DNA repair, neurotransmitter production, metabolic function, and the NAD+ pathway you are already investing in with NMN.
NAD+ Production + Methylation Support: the complete Advanced Stack
This is not about doing more for the sake of more. It is about understanding the system your NMN operates within and giving it the raw materials to work efficiently. TMG feeds into the SAMe cycle, the body's main system for distributing methyl groups where they are needed, supporting everything from gene expression to creatine synthesis to neurotransmitter production.
Supports NAD+ levels, cellular energy metabolism, and DNA repair. The foundation of your longevity routine.
A methyl donor that supports the methylation processes NMN depends on, plus cardiovascular and homocysteine metabolism support.

Trusted by advanced users
"I am usually skeptical about supplement stacks, but the science behind pairing NMN with a methyl donor made sense once I read into it. A month in and I feel more even throughout the day, less of that midafternoon dip. Quality feels solid and the liposomal delivery is a nice touch. Would recommend to anyone already on NMN looking to round things out."
"I have been taking NMN for over a year and adding TMG was the logical next step. The methylation science is well documented and I wanted to make sure my NMN was working as efficiently as possible. Three months in and my energy is more consistent, my focus is sharper, and my bloodwork markers have improved. Great pairing."
"As someone deep into the longevity space, I appreciate that GenuinePurity understands why TMG matters alongside NMN. The liposomal delivery is a real differentiator. I have tried powder TMG from other brands and the absorption difference is noticeable. This stack just makes sense for anyone serious about optimizing their NAD+ pathway."
"I did not expect to feel a difference from adding TMG but I genuinely do. My sleep quality improved, my mornings feel sharper, and I just feel more balanced overall. The bundle price makes it easy to commit to both. Highly recommend for anyone already invested in NMN."
Common questions
Do I need TMG if I already take a B-vitamin complex?
They can work well together. TMG supports methylation through a different pathway (betaine-homocysteine methyltransferase), so for many advanced users it is a complement, not a duplicate. B vitamins support methylation through the folate cycle, while TMG provides direct methyl donation through a separate enzyme system.
How will I know TMG is working?
Methylation support is not something you typically feel directly. It is a behind the scenes process that supports the NAD+ pathway you are already investing in with NMN. Some users report more consistent energy, improved focus, or better sleep quality over time, but the primary benefit is supporting the efficiency of your existing NMN routine.
Why pair NMN with TMG specifically?
Converting NMN into usable NAD+ is a methylation dependent process. Your body draws on its supply of methyl groups during this conversion. TMG is one of the body's most important methyl donors, helping replenish that supply and supporting the SAMe cycle that distributes methyl groups where they are needed.
When should I take each one?
Take NMN in the morning to support daytime NAD+ levels and energy. TMG can be taken at the same time, with or without food. Both are designed for consistent daily use as part of your longevity routine.
Why does liposomal delivery matter for TMG?
Standard TMG supplements face absorption challenges in the digestive system. Liposomal encapsulation wraps each molecule in a phospholipid shell that protects it through digestion and delivers it into the bloodstream intact, dramatically improving bioavailability compared to standard capsules or powders.
