Edited by Elaine Fletcher, Researcher

Disclosure: Eternal Elixir makes supplements, and four of our products appear in this comparison under the Eternal Elixir name. Eternal Elixir makes NMN 500mg, and it is our pick. Every figure for the other products comes from their own product pages and supplement facts panels, read in September 2026, and every study figure comes from the published paper. No brand paid to be included. Here is how we write and review content.

Best mitochondrial supplements 2026 at a glance

Prices are one-bottle prices from each seller’s own product page as of Sep 2026. Cost per serving is the price divided by the servings on the label, not by the capsule count, because several products here use two- or three-capsule servings.

Two figures stand out. Double Wood’s PQQ is the cheapest serving in the roundup at $0.33, below our NMN. And the two urolithin A products differ almost threefold in price per serving for the same 500 mg of urolithin A, though only Timeline’s material has been through the published trials.

Four mechanisms sold under one label

“Mitochondrial supplement” is a marketing category, not a biological one. The products here act on four different parts of the system, and choosing between them without knowing which is which is how people end up stacking three products that do the same job.

• NAD+ precursors (NMN, nicotinamide riboside): these supply raw material for NAD+, a coenzyme used in the reactions that turn fuel into ATP. Our guide to the best NMN supplements and our comparison of NAD+ supplements go deeper.
• Mitophagy activators (urolithin A): these are proposed to help cells clear damaged mitochondria so they can be replaced. This is the newest mechanism in the category and the one with the most direct trial data on mitochondrial markers.
• Electron-transport cofactors (CoQ10, PQQ): CoQ10 carries electrons within the respiratory chain, and PQQ is studied as a signal for making new mitochondria. These are the oldest and cheapest members of the category.
• Redox agents and metabolic intermediates (methylene blue, Ca-AKG): methylene blue can accept and donate electrons, and alpha-ketoglutarate is an intermediate in the citric acid cycle.

Two products with the same mechanism are one mechanism bought twice. If you already take NMN, a useful second product is a different class, not a second precursor.

How we ranked the best mitochondrial supplements

We did not lab-test these products. We read every live product page and supplement facts panel, converted every price to cost per label serving, and checked the published human research for each active. Eternal Elixir makes NMN 500mg and three other products in this comparison. NMN 500mg sits first as our pick for the reasons in its entry. The other seven are ordered on human evidence for the active at the dose sold, label clarity (single actives and stated doses over blends), and cost per serving.

On those measures, Timeline Mitopure leads everything else on trial evidence and Double Wood PQQ leads on price, and their entries say so.

1. Eternal Elixir NMN 500mg: our pick for a low-cost NAD+ precursor

Eternal Elixir NMN 500mg declares 500 mg of beta-nicotinamide mononucleotide per capsule, one capsule per label serving and 90 capsules per bottle, with rice flour and a cellulose capsule as the only other ingredients. At $49.99, a serving costs $0.56, and a bottle lasts three months at one a day.

It is our pick because it covers the most studied route to raising NAD+ from a single-active label, at a low cost per serving. In a randomized, double-blind trial, 80 healthy middle-aged adults took placebo or 300 mg, 600 mg or 900 mg of NMN daily for 60 days. Blood NAD rose in every NMN group, and NAD and six-minute walking distance were highest at 600 mg and 900 mg (Yi et al., 2023). The paper discloses that its first author worked for an NMN ingredient supplier.

Our 500 mg serving is just below the 600 mg dose that did best in that trial. The label serve is one capsule; if you want more, check the label and talk to your doctor first. Our product page is plain about the limits: human studies have measured NAD changes, and long-term healthy-aging outcomes are not established.

• Who it suits: most buyers starting on mitochondrial support, and anyone who wants NAD+ support at a low cost per serving.
• Who it doesn’t suit: anyone looking for a mitophagy product, which is a different mechanism.

Price: $49.99 for 90 capsules. If you are weighing NMN against nicotinamide riboside, our NR supplement comparison sets out that choice, and we also sell Nicotinamide Riboside 500mg at $59.99 for 60 capsules.

2. Timeline Mitopure Softgels: best direct trial evidence

Mitopure is the branded urolithin A used in the published trials, and that research is its strongest case. The product page lists two softgels a day for 500 mg of urolithin A, with 60 softgels lasting a month, at $99.00.

Two randomized trials used this material. In 88 middle-aged adults given 500 mg, 1,000 mg or placebo for four months, hamstring strength rose 12% at 500 mg and 9.8% at 1,000 mg compared with placebo, though the primary endpoint (peak power output) did not improve significantly (Singh et al., 2022). In 66 adults aged 65 to 90 given 1,000 mg or placebo for four months, muscle endurance improved, but the primary endpoints (six-minute walk distance and maximal ATP production in a hand muscle) did not differ from placebo (Liu et al., 2022).

The caveat most roundups skip: both trials involved employees or board members of Amazentis, the company behind Mitopure, and the Singh trial was sponsored by it. The papers say so. The softgel’s 500 mg matches the lower dose in the Singh trial.

• Who it suits: buyers who want the active with the most direct trial data on muscle and mitochondrial markers, and who aren’t price-sensitive.
• Who it doesn’t suit: budget buyers, since at $3.30 a day it is the most expensive serving here.

Price: $99.00 for 60 softgels direct from Timeline.

3. Thorne CoQ10: best established cofactor

Thorne’s CoQ10 is the conventional choice in this category. The product page lists 100 mg of CoQ10 per gelcap, one gelcap as a serving, one to two a day, and 60 gelcaps for $53.00, so a serving costs $0.88.

CoQ10 is a working part of the electron transport chain, and the body makes its own. We don’t make an outcome claim for it here, because this roundup’s other entries have more direct human trial data on mitochondrial markers. It ranks third on label clarity and brand reputation rather than on new evidence.

• Who it suits: buyers who want a long-established ingredient from a widely stocked brand.
• Who it doesn’t suit: anyone looking for the lowest price per serving or for NAD+ or mitophagy support.

Price: $53.00 for 60 gelcaps direct from Thorne.

4. Double Wood PQQ: best price per serving

Double Wood wins the price column outright. The supplement facts panel lists one capsule with 20 mg of PQQ (as pyrroloquinoline quinone disodium salt) and 60 servings, at $19.95, or $0.33 a serving. The directions say one or two capsules a day on an empty stomach and not more than four. The product page shows a lot certificate: lot 2529000 tested at 20.32 mg against an 18 to 25 mg claim range.

The human evidence for PQQ is thinner than for NMN or urolithin A, and it is mixed. In 23 untrained men doing six weeks of supervised endurance training, 20 mg a day of PQQ raised PGC-1alpha, a marker linked to making new mitochondria, more than placebo, but aerobic performance improved equally in both groups (Hwang et al., 2020). Double Wood’s 20 mg capsule matches the dose in that trial.

• Who it suits: budget buyers who want to try the PQQ mechanism.
• Who it doesn’t suit: anyone who wants a product with a proven performance effect.

Price: $19.95 for 60 capsules direct from Double Wood.

5. Eternal Elixir Methylene Blue Capsules 10mg USP: best fixed-dose redox option

Methylene blue is the odd one out here. It is not a nutrient or a precursor but a redox-active compound with drug-like effects. Each capsule supplies 10 mg of USP-grade methylene blue and 10 mg of ascorbic acid, one capsule per serving, 60 capsules for $59.99, or $1.00 a serving. A fixed capsule removes the measuring that liquid methylene blue requires.

The human evidence outside medical use is small. Our product page cites a placebo-controlled brain imaging study in 26 healthy adults that found changes in attention- and memory-related brain activity one hour after a single low dose (Rodriguez et al., 2016). One dose in one small study does not show a daily benefit or long-term safety.

Safety comes first with methylene blue. Do not take it with SSRIs, SNRIs, MAO inhibitors or other serotonergic medicines unless a prescriber specifically directs it, because serotonin syndrome can be life-threatening. It may be unsafe for people with G6PD deficiency and during pregnancy or breastfeeding, and it is not for anyone under 18. It can turn urine blue or green. Talk to your doctor before using it if you take any prescription medicine. Our methylene blue benefits guide and methylene blue dosage guide cover the details.

• Who it suits: adults who have checked with their doctor, take no serotonergic medicine, and want a precise, repeatable dose.
• Who it doesn’t suit: anyone on antidepressants or other serotonergic drugs, and anyone who wants to adjust the dose finely (our Methylene Blue Drops suit that better).

Price: $59.99 for 60 capsules. Our methylene blue supplement comparison covers that narrower market.

6. Eternal Elixir Ca-AKG 500mg: best single-active citric acid cycle intermediate

Alpha-ketoglutarate is an intermediate in the citric acid cycle, the reaction sequence that feeds the electron transport chain. Our Ca-AKG supplies 500 mg of calcium alpha-ketoglutarate per capsule, one capsule per serving, 60 capsules for $49.99, or $0.83 a serving.

We rank it sixth for a reason we state plainly: the human longevity data are not there. Our product page says the widely cited lifespan result comes from mice and that human lifespan extension has not been shown. Our Ca-AKG supplement comparison and Ca-AKG evidence review go through the research.

• Who it suits: people already taking an NAD+ precursor who want to add a different mechanism.
• Who it doesn’t suit: anyone who wants human outcome data before buying.

Price: $49.99 for 60 capsules.

7. Toniiq Urolithin A Complex: best-value urolithin A formula

Toniiq offers urolithin A at about a third of Timeline’s price, in a blend. The supplement facts panel lists a 3-capsule serving with 500 mg of urolithin A, 500 mg of pomegranate hull extract (450 mg ellagic acid), 400 mg of partially hydrolyzed guar gum and 100 mg of NMN, and 30 servings per bottle. The directions say three capsules daily with a meal. At $34.97, a serving costs $1.17.

The limitation is evidence transfer. The trials above used Mitopure, and Toniiq’s urolithin A is a different source, so those results don’t automatically apply. The 100 mg of NMN is well below the doses used in NMN trials, and the blend makes it impossible to say which ingredient does what.

• Who it suits: buyers who want urolithin A at a lower price and accept that the trials used another brand’s material.
• Who it doesn’t suit: anyone who wants the exact material from the published trials.

Price: $34.97 for 90 capsules direct from Toniiq.

8. Eternal Elixir NMN Advanced Longevity Complex 1200mg: best one-bottle stack

This is our multi-ingredient formula. Each 2-capsule serving lists 500 mg of NMN, 250 mg of TMG, 200 mg of pterostilbene, 100 mg of trans-resveratrol, 100 mg of quercetin phytosome and 50 mg of apigenin, 1,200 mg of actives in all, with 60 vegan capsules for $64.99, or $2.17 a serving.

We rank it last among our entries on purpose. It is a blend, so it has the same attribution problem as any multi-ingredient formula. Where it earns a place is convenience: six actives in two capsules, including TMG. If you would rather build the stack yourself, our longevity stack comparison prices the do-it-yourself route.

• Who it suits: buyers who want one bottle instead of four and accept the trade-off.
• Who it doesn’t suit: anyone who wants to know which ingredient is doing what.

Price: $64.99 for 60 capsules.

How to take them: label directions side by side

Each label gives its own directions, and some conflict with how people assume these products work. This is what each product page or facts panel says (Sep 2026):

Choosing by goal

• You want the best-studied way to raise NAD+: an NMN product such as our NMN 500mg. Nicotinamide riboside is the alternative precursor.
• You want the most direct data on mitochondrial and muscle markers: Mitopure urolithin A, at a higher price.
• You want the cheapest way to try a mitochondrial product: Double Wood PQQ.
• You want a second mechanism alongside NMN: urolithin A, CoQ10 or Ca-AKG, rather than a second NAD+ precursor.
• You take an antidepressant or any other serotonergic medicine: skip methylene blue and talk to your doctor about the rest.
• You want one bottle: our NMN Advanced Longevity Complex, or Toniiq’s urolithin A blend if urolithin A is the priority.

Whatever you choose, add one product at a time and give it at least two to three months, since the trials above ran for 60 days to four months. Our guide to the best supplements for energy covers products aimed at how you feel day to day, which is a different question from mitochondrial markers.

Who funded the headline trials

The strongest studies in this roundup carry industry ties, disclosed in the papers themselves. The urolithin A trials involved Amazentis employees and board members, and the Singh trial was sponsored by the company. The NMN dose trial’s first author worked for an NMN ingredient supplier. A 2023 PQQ memory study in adults aged 20 to 65 included authors from Mitsubishi Gas Chemical, which sells PQQ under the BioPQQ name (Tamakoshi et al., 2023).

This is normal in supplement research, and randomization and blinding still do real work. But roundups that cite these papers as independent academic findings give readers an incomplete picture, and anyone deciding between a $3.30 serving and a $0.33 serving should have the full one.

What mitochondrial supplements will not do

They will not fix tiredness caused by short sleep, low iron, thyroid problems or a medicine side effect. If fatigue is new, persistent or came on quickly, talk to your doctor and get blood work before you buy a supplement.

They will not feel like a stimulant. Nothing in this comparison contains caffeine, and buyers expecting an energy-drink kick often decide a product does nothing when they don’t feel one.

And they have not been shown to extend human lifespan. The trials above ran for two to four months and measured blood markers, muscle function and walking tests. Men building a broader routine may find our guide to supplements for men over 40 a better starting point, and our longevity supplement comparison and spermidine comparison cover related mechanisms.

Frequently asked questions about mitochondrial supplements

What is the best mitochondrial supplement?

Eternal Elixir NMN 500mg is our pick: 500 mg of NMN per capsule, with no blend, at $0.56 a serving from a 90-capsule bottle, and NMN reliably raises blood NAD in trials. Timeline Mitopure has the most direct trial data on muscle and mitochondrial markers, at $3.30 a day, and Double Wood PQQ is the cheapest serving here at $0.33.

What supplement helps mitochondria the most?

No single supplement has been shown to be best. Urolithin A has the most direct trial data on mitochondrial and muscle markers, NMN has the clearest evidence for raising NAD+, and PQQ raised a marker of new mitochondria in one small trial without improving performance. Which helps most depends on the mechanism you want to support.

What rebuilds your mitochondria?

Exercise training is the most reliable driver. In the PQQ trial above, six weeks of supervised endurance training raised peak oxygen uptake in both the PQQ and placebo groups, while the supplement changed only a molecular marker. Supplements such as urolithin A and PQQ are studied for their effects on mitochondrial turnover and new mitochondria, but they add to training rather than replace it.

What are the best mitochondrial peptides?

Mitochondria-targeted peptides are drug candidates, not dietary supplements, and none of the products in this comparison contains them. If you are considering one, talk to your doctor.

What is the best mitochondria supplement for weight loss?

We would not buy any of these for weight loss. They are not weight-loss products, and the trials cited here were designed around NAD+, muscle function and mitochondrial markers.

How much do mitochondrial supplements cost per month in the US?

At one label serving a day and the September 2026 prices above: about $10 for Double Wood PQQ, $17 for Eternal Elixir NMN 500mg, $25 for Eternal Elixir Ca-AKG, $27 for Thorne CoQ10, $30 for Eternal Elixir Methylene Blue, $34.97 for Toniiq Urolithin A Complex, $64.99 for the Eternal Elixir Advanced Longevity Complex and $99.00 for Timeline Mitopure.

Is CoQ10 or PQQ better for mitochondria?

They act differently rather than competing. CoQ10 works within electron transport, while PQQ is studied as a signal for making new mitochondria. PQQ is cheaper per serving here, and neither has shown a clear performance benefit in the trials we cite. Some people take both.

Can you take NMN and urolithin A together?

They target different mechanisms, precursor supply and mitophagy, so there is no overlap in combining them. No trial has tested the pair, so any claim of added benefit is speculation. At the prices above, our NMN 500mg and Timeline Mitopure together cost $3.86 a day.

The verdict: which mitochondrial supplement should you buy?

Our pick: Eternal Elixir NMN 500mg. It supplies 500 mg of NMN per capsule from the most studied route to raising NAD+, at $0.56 a serving from a 90-capsule bottle.

If direct trial data are what you are paying for: Timeline Mitopure, whose exact material has been through two randomized trials, industry ties and all.

If price comes first: Double Wood PQQ at $0.33 a serving, accepting a thinner evidence base.

If you want one bottle instead of several: our NMN Advanced Longevity Complex, accepting that a blend can’t tell you which active did the work.

Eternal Elixir also sells several single-active mechanisms in one place, including NMN, nicotinamide riboside, Ca-AKG, spermidine and methylene blue. For most buyers building a routine, that is the case for starting with NMN and adding a second mechanism later.

More buying guides are on our blog and in Supplement Guides, or you can browse the Eternal Elixir shop.
