What's in NMN Complete?
NMN Complete is a UK-made food supplement that combines four ingredients used in longevity-focused formulas: nicotinamide mononucleotide (NMN), trimethylglycine (TMG), pterostilbene and apigenin. Each serving of two vegan capsules provides 1350mg of actives. This page explains what each ingredient is and why they are combined. It is factual reference information, not health advice.

The four ingredients
What each ingredient is
NMN (Nicotinamide Mononucleotide) — 750mg. Nicotinamide mononucleotide is a naturally occurring molecule and a direct precursor in the NAD+ salvage pathway — the route cells use to produce and recycle NAD+, a coenzyme found in every living cell. Read more in our what is NMN guide.
TMG (Trimethylglycine) — 500mg. Trimethylglycine (also called betaine) is a methyl donor: a molecule that supplies methyl groups used in the body's methylation reactions. It is commonly paired with NMN because NAD+-related metabolism involves the methylation of nicotinamide. Read more in our what is TMG guide.
Pterostilbene — 50mg. Pterostilbene is a naturally occurring stilbene compound found in blueberries. It is a dimethylated (methylated) analogue of resveratrol, which makes it more fat-soluble, and is often used in NAD+ and longevity formulas as an alternative to resveratrol. Read more in our what is pterostilbene guide.
Apigenin — 50mg. Apigenin is a flavone — a type of plant flavonoid — found in foods such as parsley and chamomile. It is studied within NAD+ research in relation to the CD38 enzyme. Read more in our what is apigenin guide.

The rationale
Why these four ingredients are combined
NMN supplies the NAD+ salvage pathway; TMG provides methyl groups relevant to nicotinamide methylation; pterostilbene and apigenin are longevity-research compounds frequently formulated alongside NMN. Together they reflect a common "NAD+ stack" approach to daily supplementation. This is biochemical context only — food supplements are not intended to diagnose, treat, cure or prevent any disease.
NMN
NAD+ precursor. Supplies the NAD+ salvage pathway cells use to produce and recycle NAD+.
TMG
Methyl donor. Provides methyl groups relevant to the methylation of nicotinamide.
Pterostilbene
Stilbene compound. A methylated analogue of resveratrol, often used in NAD+ formulas.
Apigenin
Plant flavone. Studied within NAD+ research in relation to the CD38 enzyme.
How it compares
NMN Complete vs single-ingredient NMN
If you want NMN on its own, NMN 1000mg provides 1000mg of pure nicotinamide mononucleotide per serving. NMN Complete instead provides 750mg NMN plus TMG, pterostilbene and apigenin for a broader daily formula.
- NMN 1000mg — a single-ingredient supplement: 1000mg of pure nicotinamide mononucleotide per serving.
- NMN Complete — 750mg NMN plus 500mg TMG, 50mg pterostilbene and 50mg apigenin (1350mg of actives) per serving.
Common questions
NMN Complete FAQ
Each serving (2 capsules) provides 750mg NMN, 500mg TMG, 50mg pterostilbene and 50mg apigenin — 1350mg of actives — in 60 vegan capsules.
No. NMN Complete uses pterostilbene, a methylated analogue of resveratrol, rather than trans-resveratrol.
TMG is a methyl donor. It is commonly combined with NMN because NAD+-related metabolism involves methylation of nicotinamide. This is biochemical context, not a health claim.
Yes. NMN Complete uses vegan capsules, is made in the UK and is third-party tested. A Certificate of Analysis is available on request.
The suggested use is two capsules daily with water, preferably with food. Do not exceed the recommended daily intake.
Plain NMN, such as NMN 1000mg, is a single-ingredient supplement. NMN Complete adds TMG, pterostilbene and apigenin alongside NMN.
NMN Complete, four ingredients in one
NMN, TMG, pterostilbene and apigenin — 1350mg of actives per serving in 60 UK-made, third-party tested vegan capsules, with a Certificate of Analysis available on request.
