What is it? Vitality Supplements NMN + TMG is a two-ingredient food supplement providing 750mg of NMN (nicotinamide mononucleotide) and 750mg of TMG (trimethylglycine) per 2-capsule serving, a total of 1500mg in a balanced 1:1 ratio.
How much NMN per serving? 750mg, verified at a purity of at least 98% by independent analysis.
How much TMG per serving? 750mg — matched milligram-for-milligram with the NMN, rather than the token amounts common in NAD+ products.
How many capsules? 60 vegetarian HPMC capsules per pouch — 30 servings, a 30-day supply at two capsules daily.
How is it taken? As a food supplement, adults take 2 capsules daily with water. Do not exceed the stated recommended daily dose.
Is it tested? Every batch is tested at an independent ISO/IEC 17025 accredited laboratory for identity, purity and heavy metals. A certificate of analysis is available on request by batch number.
Where is it made? Manufactured in the United Kingdom to GMP standards.
Who should not take it? Not for under-18s. If pregnant, breastfeeding, taking medication or under medical supervision, consult a healthcare professional before use.
What is NMN? A nucleotide occurring naturally in trace amounts in broccoli, avocado and edamame. It is the phosphorylated form of nicotinamide riboside and the direct biosynthetic precursor to NAD+, converted in a single enzymatic step by the NMNAT enzyme family.
What is TMG? Trimethylglycine, also called betaine, found naturally in beetroot, spinach and wheat germ. Its three methyl groups make it one of the principal dietary methyl donors.
How does it compare with NMN Complete? NMN + TMG contains those two actives only. NMN Complete adds pterostilbene and apigenin alongside the same 750mg NMN and 750mg TMG.

Most NAD+ products publish a blend weight. We publish the map: what is in the capsule, how much of each, and in what proportion. Every figure below is printed on the pouch and confirmed on the batch certificate.
A two-ingredient build: pure NMN and TMG in a balanced 1:1 ratio, capsuled and tested in the UK. Here is each step.
NAD+ is a coenzyme found in every living cell. NMN sits one enzymatic step from it. The other three were chosen for what they are chemically — and each is dosed in the open.

Before a single pouch ships, every batch is sent to an independent ISO/IEC 17025-accredited laboratory. Ingredient identity and amounts confirmed, contaminants screened. If it fails any specification, it does not ship.
Two ingredients, each named and individually dosed — no proprietary blend. Every amount printed plainly on the label.

We would rather be honest than make a sale. Here is who this product is for and who it is not for.
Specification comparison against typical UK-available NAD+ complex products (spec-sheet analysis, 2026).

So many NAD+ brands give a token NMN dose and hide the rest. This one lists all two ingredients with individual amounts. Clean label.
Exactly what I wanted — a full 750mg of NMN, plus 750mg TMG and two more, each dosed. No token amounts. Third-party tested too.
UK made, third-party tested, every milligram on the label. Exactly the transparency I look for in a supplement. Put it straight on subscription.
It is a 2-ingredient food supplement providing 1500mg per 2-capsule serving: 750mg pure NMN (nicotinamide mononucleotide), 750mg TMG (trimethylglycine). All amounts are stated on the label.
NMN (nicotinamide mononucleotide) is a naturally occurring molecule related to vitamin B3, found in small amounts in some foods. We describe it factually and make no claim about what it does in the body.
TMG (trimethylglycine, or betaine) is a compound found naturally in beetroot, spinach and wheat germ. Its three methyl groups make it one of the principal dietary methyl donors. Each is named and individually dosed on the label.
Both are NAD+ precursors — see our NMN vs NR comparison. NMN is the phosphorylated form of NR (nicotinamide riboside), which places it one enzymatic step from NAD+ — NR must first be phosphorylated by nicotinamide riboside kinase before it can follow the same route. NMN is converted directly by the NMNAT enzyme family. This product uses beta-NMN at a verified purity of at least 98%.
TMG (trimethylglycine) is one of the body's principal dietary methyl donors, carrying three methyl groups. Pairing it with NMN is a common formulation choice in NAD+ products; what is less common is including it at a comparable amount. Here it is 750mg, matched milligram-for-milligram with the NMN rather than included at a token level.
NMN has been the subject of peer-reviewed human and animal research. A randomised, placebo-controlled trial published in Science in 2021 by Yoshino and colleagues at Washington University examined 250mg daily over 10 weeks in postmenopausal women with prediabetes. Earlier work by Yoshino, Mills, Yoon and Imai in Cell Metabolism (2011) characterised NMN in mice. Research is ongoing and findings in one population do not transfer automatically to another; we link the primary sources so you can read them directly.
750mg NMN + 750mg TMG = 1500mg per 2-capsule serving. Each figure is printed individually on the supplement-facts panel, so you can check the arithmetic yourself.
As a food supplement, adults take 2 capsules daily with water. Do not exceed the stated recommended daily dose.
60 capsules per pouch, 2 capsules per serving — a 30-day supply. All two ingredient amounts are per 2-capsule serving, printed on the supplement-facts panel.
Yes. Every batch is tested at an independent ISO/IEC 17025-accredited laboratory before release, confirming ingredient identity, amounts and NMN purity, and screening contaminants. It is also GMP certified and UK made. A Certificate of Analysis is available on request — email us with your batch number.
The NMN is verified to a purity of at least 98% through independent testing, with the result recorded on the batch Certificate of Analysis. The figure describes the material; we make no claim about what it does.
Do not use if you are under 18, pregnant or breastfeeding. If you take any medication or have a health condition, consult a doctor before use. Keep out of reach of children. Discontinue use and consult a doctor if adverse reactions occur.
