Quick Answer

What are longevity supplements and which ones have the best research?

Longevity supplements are food supplement ingredients studied in the context of ageing biology and cellular health. The ingredient with the largest recent published human research base is NMN — a NAD+ precursor with 30+ peer-reviewed human studies and a 2023 systematic review of 10 RCTs with 437 participants. Other well-researched ingredients include Trans-Resveratrol (sirtuin research), AHCC (research since 1989) and NMNH (newer, developing base). None have authorised health claims under UK regulations. Quality criteria: independent ISO/IEC 17025 batch testing, >99% purity, full dose disclosure, CoA on request.

Key Takeaways
  • NMN has the largest recent published human research base of any NAD+ precursor — 30+ studies, 10-RCT systematic review
  • Trans-Resveratrol is the most studied polyphenol in longevity science — research focuses on SIRT1 activation
  • AHCC has an extensive published research base dating to 1989 — distinct from NAD+ precursors
  • No longevity supplement ingredient has an authorised health claim under UK food supplement regulations
  • Quality criteria that matter: independent ISO/IEC 17025 batch testing every batch, not just selected ones
  • Always request a Certificate of Analysis for the specific batch you received
The Category

What are longevity supplements?

Longevity supplements are food supplement ingredients that have been studied in the context of ageing biology and cellular health. They are not a single ingredient or product — they are a category of compounds that have attracted significant scientific attention over the past two decades.

The category has grown substantially since the early 2020s, driven by a growing body of published peer-reviewed research into the biology of ageing — particularly around NAD+ metabolism, sirtuin enzymes, cellular energy production and the compounds that influence these pathways. See our Vitality Longevity Protocol → for the full science.

Key longevity supplement ingredients include NMN, NMNH, Trans-Resveratrol, Pterostilbene, TMG, Apigenin and AHCC. Each is a distinct compound with its own chemical identity, mechanism of interest and published research base.

Important: As food supplement ingredients sold in the UK, none of these compounds have authorised health claims under UK food supplement regulations. This guide describes what published research has investigated about these compounds — not health claims for any product.

The published research base for longevity supplement ingredients has grown substantially since 2020 — moving from primarily preclinical studies to peer-reviewed human trials.

The Ingredients

Key longevity supplement ingredients

The following covers the most widely studied longevity supplement ingredients available in the UK. Each description summarises what published research has investigated about the compound — not health claims for any product. For full ingredient guides see What is NMN? → and What is NAD+? →

NMN

Nicotinamide Mononucleotide
Most studied

NMN is a naturally occurring compound found in trace amounts in edamame, broccoli and avocado. It is a biosynthetic precursor to NAD+ — a coenzyme present in every living cell. Published peer-reviewed research has documented NAD+ level changes following NMN supplementation in multiple human trials across doses from 250mg to 900mg per day. One step from NAD+ via NMNAT enzymes. Read the NMN guide →

Research base: 30+ peer-reviewed human studies. Systematic review of 10 RCTs with 437 participants (Yi et al. 2023) confirmed consistent NAD+ elevation with strong safety profile. See dosage guide →

NAD+ Precursor Vitamin B3 Derivative Found in food

NMNH

Dihydronicotinamide Mononucleotide
Newer

NMNH is the reduced form of NMN — the nicotinamide ring is in its reduced state. It is a structurally distinct compound and a newer ingredient in the longevity supplement space. Published preclinical and early human research has investigated its properties as an NAD+ precursor. Its research base is developing actively. NMN vs NMNH guide →

Research base: Newer than NMN — smaller but active and growing published research base. Distinct chemical properties under active investigation.

Trans‑Resveratrol

Stilbenoid Polyphenol · 98% trans-isomer
Extensively studied

Resveratrol is a polyphenol found in red grape skin, Polygonum cuspidatum (Japanese knotweed) and blueberries. One of the most extensively studied polyphenols in longevity science. Published research has focused on its relationship to SIRT1 activation — sirtuins are NAD+-dependent deacetylases. NMN and Resveratrol guide →

Trans vs Cis: Trans-resveratrol is the biologically active isomer and the form used in published research. Look for 98%+ trans-isomer purity, verified independently.

Stilbenoid Polyphenol Sirtuin research Plant-derived

Pterostilbene

Stilbenoid Polyphenol · ~4× bioavailability
High bioavailability

Pterostilbene is a structural analogue of resveratrol found in blueberries and grapes. It differs from resveratrol in having two methoxy groups where resveratrol has two hydroxyl groups. Published pharmacokinetic studies have documented approximately 4× higher oral bioavailability for pterostilbene compared to resveratrol due to this structural difference.

Research base: Growing published research base. Frequently studied alongside NMN in longevity research contexts. Included in NMN Complete 1350mg →

TMG

Trimethylglycine · Betaine
Methyl Donor

TMG (Trimethylglycine), also known as betaine, is a naturally occurring compound found in beetroot, spinach and quinoa. It functions as a methyl donor in the body's one-carbon metabolism. TMG is discussed alongside NMN in longevity research literature in the context of methylation balance. It is a distinct ingredient — not an NAD+ precursor.

Research base: Established ingredient with a broad published research base across multiple contexts.

Methyl Donor Found in beetroot One-carbon metabolism

Apigenin

Botanical Flavone
CD38 research

Apigenin is a naturally occurring flavone found in parsley, chamomile and celery. It has been studied in relation to CD38 — an enzyme that consumes NAD+ and whose activity increases with age. Published research has investigated apigenin's relationship to CD38 inhibition, making it of interest in NAD+ metabolism research contexts. See Pillar 1: NAD+ & Cellular Energy →

Research base: Growing published research base. Included in longevity formulas as a botanical flavone complement to NAD+ precursors.

What the science says

The published research on longevity supplement ingredients has matured significantly since 2020. The following summarises the current state of the evidence base — not as health claims, but as factual descriptions of what has been studied and published. For full references, see our research references page →

NMN research

A systematic review (Yi et al. 2023) covering 10 randomised controlled trials with 437 participants documented that NMN supplementation consistently elevated blood NAD+ levels across doses from 250 to 900mg per day, with a strong safety profile and no significant adverse events. Multiple individual peer-reviewed human studies have explored NMN across a range of research areas. See the full NMN dosage guide →

Resveratrol research

Resveratrol is one of the most studied polyphenols in the published scientific literature. Its relationship to sirtuin enzymes — particularly SIRT1 — has been documented extensively in both in vitro and in vivo research. Human studies have explored resveratrol across metabolic, cardiovascular and longevity biology contexts. See our NMN and Resveratrol guide →

AHCC research

AHCC has one of the most extensive published research bases of any mushroom-derived supplement ingredient, with human studies published since the early 1990s across multiple research contexts.

The important caveat: The above describes what has been studied and published about these compounds as substances — not what supplement products containing them will do. Product quality, purity and dose are critical factors. Independent batch testing at stated doses is the only way to verify you are consuming what the label states.

Buying Guide

How to choose a longevity supplement

The longevity supplement market in the UK varies enormously in quality. The ingredient name on the label is the starting point — not the end point. Here is what to verify before buying. For a full buying guide, see How to choose an NMN supplement →

  • Independent batch testing: Every production batch — not just selected batches or raw ingredients — should be tested by an independent ISO/IEC 17025-accredited laboratory. CoA should be available on request for any specific batch.
  • Verified purity: For NMN, look for greater than 99% β-NMN purity verified by HPLC. For resveratrol, look for 98%+ trans-isomer purity. Purity should be confirmed in the Certificate of Analysis.
  • Full dose disclosure: Every ingredient and its exact milligram amount should be disclosed on the label. No proprietary blends. No "complex" totals that hide individual doses.
  • UK manufacturing: UK-manufactured products are subject to UK food supplement regulations and trading standards enforcement. Manufacturing origin should be clearly stated.
  • Compliant claims: No health claims are authorised for most longevity supplement ingredients under UK regulations. Brands making specific therapeutic claims may not be compliant — compliance is a quality signal.
  • Transparent brand: A reputable brand should have a clear contact address, respond to CoA requests promptly and be able to answer questions about manufacturing and testing processes.
Red Flags

What to avoid

These are the warning signs that a longevity supplement product may not meet quality standards.

  • No purity information: Vague claims like "high purity" or "ultra pure" without a specific percentage verified by independent testing are not sufficient.
  • Manufacturer's own lab testing only: Testing conducted by the brand's own laboratory is not independent. Look for third-party ISO/IEC 17025-accredited laboratory testing.
  • No Certificate of Analysis available: If a brand cannot or will not provide a CoA for the specific batch you received, that is a significant red flag.
  • Proprietary blends: Any formula that lists a "NMN complex" or similar combined total without disclosing individual ingredient doses is not fully transparent.
  • Unauthorised health claims: Brands claiming their supplements "reverse ageing", "boost NAD+ levels" or make other specific therapeutic claims for ingredients without authorised health claims may not be compliant with UK regulations.
  • Unrealistically low prices: Independent batch testing by accredited laboratories, UK manufacturing and verified purity all add cost. Products priced significantly below the market often cut corners on one or more of these.
  • No batch number on packaging: Without a batch number, there is no way to request or verify the Certificate of Analysis for what you received.
FAQ

Common questions

Longevity supplements are food supplement ingredients studied in ageing biology and cellular health contexts. As food supplements, none have authorised health claims under UK regulations. The published research on compounds such as NMN, resveratrol and AHCC is extensive and growing. Whether any product delivers what published research has studied depends on purity, dose and quality — not just the ingredient name on the label.
The longevity supplement ingredients with the most substantial published human research include NMN (30+ peer-reviewed human studies, systematic review of 10 RCTs with 437 participants), resveratrol (one of the most studied polyphenols in longevity science) and AHCC (extensive published research base since 1989). When choosing, prioritise: independent batch testing by ISO/IEC 17025-accredited laboratory, verified purity, full dose disclosure, UK manufacturing and compliant claims.

NMN (Nicotinamide Mononucleotide) is a naturally occurring compound and a biosynthetic precursor to NAD+ — a coenzyme present in every living cell, participating in over 500 enzymatic reactions. Published research documents consistent NAD+ decline with age. A 2023 systematic review of 10 RCTs with 437 participants confirmed consistent NAD+ elevation from NMN supplementation at 250-900mg per day with a strong safety profile. Read the full NMN guide →
NMN and resveratrol are structurally unrelated compounds with different mechanisms. NMN is a biosynthetic precursor to NAD+. Resveratrol is a polyphenol studied in relation to sirtuin enzyme activation — sirtuins are NAD+-dependent enzymes. They are frequently discussed together in longevity research because both relate to the NAD+-sirtuin axis. Read our full guide →
Longevity supplement ingredients such as NMN have demonstrated strong safety profiles in published human research, with no significant adverse events at standard doses across multiple trials. All supplements should be purchased from brands that independently test every batch and disclose full ingredient doses. Consult a qualified healthcare professional before starting any supplement, particularly if you are pregnant, breastfeeding, taking medication or have a pre-existing medical condition. All Vitality Supplements products are food supplements — not medicines.
Six criteria: 1) Independent batch testing by ISO/IEC 17025-accredited laboratory with CoA available on request. 2) Verified purity (>99% β-NMN for NMN, 98%+ trans-isomer for resveratrol). 3) Full dose disclosure — no proprietary blends. 4) UK manufacturing. 5) Compliant claims — no unauthorised therapeutic claims. 6) Batch number on packaging.

The terms are often used interchangeably. "Longevity supplements" generally refers to ingredients studied in ageing biology — NAD+ precursors, sirtuins, cellular energy metabolism. "Anti-ageing supplements" is a broader category term. Neither term constitutes a health claim under UK food supplement regulations — both are descriptive category terms used to describe the research context of the ingredients, not claims about what products do.
