We have a commercial interest in this subject. No authorised EU/UK health claims exist for NMN. Authorised CoQ10/ubiquinone claims listed below. Food supplement — not a medicine. Consult your GP if on statins or prescription medication.
⚡ Direct Answer — NMN and CoQ10
NMN converts to NAD+ which feeds electrons into the mitochondrial electron transport chain at Complex I. CoQ10 acts as the electron carrier between complexes I, II and III. Both operate inside the same mitochondrial energy production machinery — at different but adjacent points. Both decline with age. The combination targets two different mitochondrial bottlenecks simultaneously. Human evidence for each individually is substantial. The 2024 Ahmadi crossover RCT showed NAD+ precursor (NR) + CoQ10 improved mitochondrial markers in CKD patients — the closest published human data for the combination rationale. No NMN + CoQ10 RCT in healthy ageing populations exists yet. Food supplement — not a medicine.
📋 In This Guide:
Section 1 — The Mitochondrial Energy Map
To understand why NMN + CoQ10 is mechanistically coherent, you need a basic map of how mitochondria produce ATP — the energy currency of every cell.
⚡ MITOCHONDRIAL ELECTRON TRANSPORT CHAIN — WHERE EACH COMPOUND ACTS
NMN → NAD+ ROLE
NMN → converts to NAD+ → feeds electrons to Complex I → powers the electron transport chain → drives ATP synthesis at Complex V
CoQ10 ROLE
CoQ10 (ubiquinone) → electron carrier between Complex I, II and III → shuttles electrons along the ETC → also functions as fat-soluble antioxidant in mitochondrial membrane

The critical point: NAD+ and CoQ10 don't just both "support energy" — they operate at specific, different, but adjacent points in the same biochemical process. If either is depleted, the electron transport chain runs less efficiently — regardless of how much of the other is available. This is the mechanistic argument for combination supplementation. Educational context — food supplement, not a medicine.
Section 2 — The Age Decline Problem
Both NAD+ and CoQ10 decline with age — and both declines affect the same downstream mitochondrial machinery.
📉 NAD+ Decline with Age
- ~50% decline between age 40 and 60 in human tissues
- Driven by reduced NAMPT activity (salvage pathway)
- Increased NAD+ consumption by sirtuins, PARPs, CD38
- Reduced precursor availability from diet and synthesis
- Documented across multiple tissue types in human studies
📉 CoQ10 Decline with Age
- Peaks around age 20 in human heart tissue
- 40–72% reductions reported in older adult tissue studies
- Driven by reduced mevalonate pathway synthesis
- Increased oxidative consumption with age
- Further depleted by statin use (mevalonate pathway inhibition)
⚠️ The Combined Decline Hypothesis
If you restore NAD+ availability via NMN — but CoQ10 is severely depleted — the electron transport chain still runs sub-optimally because the electron carrier between complexes is rate-limited. The converse applies equally. Both declines affect the same downstream process. This is the mechanistic argument for combination support — not just a marketing convenience. Educational context — food supplement, not a medicine.

NMN — Published Human Trials

CoQ10 — Human Evidence Base
🫀 Q-SYMBIO Trial (Heart Failure) — PubMed 25282031
CoQ10 300mg/day in heart failure patients — significantly reduced major adverse cardiovascular events. One of the most robust CoQ10 RCTs published.
📊 2024 Systematic Review and Meta-Analysis (medRxiv)
Comprehensive review of CoQ10 cardiovascular trials 1990–2024 — evidence supporting improved systolic function, endothelial function and exercise capacity. Recommends CoQ10 as synergistic adjunctive therapy.
🔬 Wieland et al. 2024 (Frontiers in Bioscience, PubMed 39614446)
CoQ10 stimulated oxidative phosphorylation in primary human dermal fibroblasts from 10 donors — confirmed by FLIM imaging showing shift to longer NADH lifetimes indicating activated mitochondria.
😴 ME/CFS Fatigue — PMC10779395
Ubiquinol (reduced CoQ10) 150mg/day for 3 months in RCT — improved fatigue markers and mitochondrial function in ME/CFS patients with depleted CoQ10 tissue levels.
Section 4 — The 2024 Combination Trial Data
📚 Ahmadi et al. (2024, medRxiv) — doi:10.1101/2024.08.23.24312501
Randomised crossover clinical trial of NR and CoQ10 in chronic kidney disease (CKD) patients · n=25 · mean age 61 years
✅ CoQ10 significantly reduced inflammatory markers (CRP and IL-13)
✅ NR improved mitochondrial bioenergetic health index (BHI)
✅ Both increased gene activity related to metabolism and immunity
⚠️ Important Context — What This Trial Does and Doesn't Show
What it shows: That an NAD+ precursor (NR) and CoQ10 in combination produce measurable mitochondrial and inflammatory effects in humans. NR and NMN share the same Preiss-Handler pathway mechanism (Christen 2025) — making this the most relevant published human data for the NMN + CoQ10 combination rationale.
What it doesn't show: This was a CKD patient population — not healthy adults. Results in a diseased population don't automatically translate to healthy ageing individuals. This trial was also a preprint at time of writing — not yet peer-reviewed. No published human RCT has directly tested NMN + CoQ10 in a healthy ageing population. Educational context — food supplement, not a medicine.
Section 5 — Ubiquinone vs Ubiquinol
| Property | Ubiquinone (Oxidised) | Ubiquinol (Reduced) |
|---|---|---|
| State | Oxidised — electron-accepting form | Reduced — electron-donating form |
| Primary role | Electron carrier in ETC · standard supplement form | Active antioxidant form in blood and tissues |
| Bioavailability | Good — body converts to ubiquinol | Higher plasma levels after single dose |
| Best for | Most healthy adults under 50 — converted efficiently | Older adults or those with conversion concerns |
| Cost | Standard — widely available | Premium — more expensive to produce |
| In our capsules | ✅ Ubiquinone (standard supplemental form) | Not in current formulation |
Section 6 — Authorised CoQ10 Health Claims
Authorised under EU Regulation 1924/2006 retained in UK law · No authorised EU/UK health claims exist for NMN
✅ Coenzyme Q10 contributes to normal energy-yielding metabolism
✅ Coenzyme Q10 contributes to the reduction of tiredness and fatigue
✅ Coenzyme Q10 contributes to normal functioning of the nervous system
✅ Coenzyme Q10 contributes to the maintenance of normal blood pressure
✅ Coenzyme Q10 contributes to normal cardiac function
These are the only authorised claims made for the CoQ10 component. No authorised EU/UK health claims for NMN. Food supplement — not a medicine.
Section 7 — Practical Guide
| Recommendation | Rationale |
|---|---|
| Always take with food | CoQ10 is fat-soluble — absorption significantly improved with a fat-containing meal · NMN also better absorbed with food |
| Morning with breakfast | Consistent with published NMN trial timing · aligns with circadian NAD+ biology |
| Take consistently daily | CoQ10 takes 2–4 weeks to reach stable plasma levels · NMN effects are cumulative |
| Give it 8–12 weeks minimum | Consistent with published NMN and CoQ10 trial durations before assessment |
| ⚠️ Consult GP if on statins | Statins inhibit mevalonate pathway — same pathway that produces CoQ10 endogenously. Statin users may have particularly depleted CoQ10. Discuss with GP before adding. |
| Consult GP if on any prescription medication | Standard advice for any supplement combination |

Section 9 — FAQ
Why combine NMN and CoQ10?
Both operate inside the mitochondrial electron transport chain — NMN (via NAD+) at Complex I, CoQ10 between complexes I, II and III. Both decline with age. The combination targets two different but adjacent mitochondrial bottlenecks simultaneously. Food supplement — not a medicine.
Is there a human trial for NMN + CoQ10?
The most relevant published human data is Ahmadi et al. (2024) — a randomised crossover trial of NR (an NAD+ precursor sharing NMN's mechanism) + CoQ10 in CKD patients. CoQ10 reduced inflammatory markers; NR improved mitochondrial bioenergetics. No published RCT has directly tested NMN + CoQ10 in healthy ageing populations. Educational context — food supplement, not a medicine.
What is the difference between ubiquinone and ubiquinol?
Ubiquinone is the oxidised standard form — the body converts it to ubiquinol. Ubiquinol is the reduced active form with higher plasma levels after single dosing. For most healthy adults ubiquinone is converted efficiently. Older adults or those with metabolic concerns may benefit from ubiquinol. Our capsules use ubiquinone. Food supplement — not a medicine.
Should I take CoQ10 if I'm on statins?
Statins inhibit the mevalonate pathway — the same pathway that produces CoQ10 endogenously. Statin users may have particularly depleted CoQ10 levels. Consult your GP before adding any supplement if you are on statins. Food supplement — not a medicine.
