Pyrroloquinoline quinone, or PQQ, is a small redox-active compound found in trace amounts in foods like natto, parsley, kiwi fruit and green tea. It works inside cells as a cofactor and antioxidant, and in cell and animal studies it activates a signalling pathway (CREB and PGC-1alpha) that drives mitochondrial biogenesis, the process of building new mitochondria rather than simply protecting the ones you already have.¹ That mechanism is why PQQ gets marketed alongside CoQ10 in the "cellular energy" category: CoQ10 supports the mitochondria you have, while PQQ's proposed role is prompting cells to make more of them.

Be aware going in that this is a genuinely smaller evidence base than most ingredients on this site. Most of the human trials are small, short (six to twelve weeks), and run out of Japan, often with researchers affiliated with Mitsubishi Gas Chemical, the company that manufactures the original branded PQQ ingredient. That doesn't make the findings meaningless, but it's a narrower and more preliminary body of research than something like CoQ10 or creatine, and worth knowing before you spend on it. When shopping, the main thing to check is which raw ingredient a product actually contains: a traceable, regulator-assessed branded form, or an unbranded "PQQ disodium salt" with a purity percentage but no independent verification behind it.

Key Takeaways (TL;DR)

• MGCPQQ (also sold as BioPQQ) is the fermentation-derived, EFSA-assessed branded ingredient used in most of the published human trials.
• PureQQ is a different branded PQQ made by chemical synthesis rather than fermentation; it's traceable and FDA GRAS-notified, but isn't the ingredient behind the Japanese cognitive and mitochondrial trials.
• Many UK listings use unbranded "PQQ disodium salt" with a purity claim but no named, independently verified raw material.
• 20mg per day is the ceiling, not just a marketing number: it's the dose the EFSA safety opinion assessed and the dose used in the human trials, so more isn't automatically better.
• PQQ is frequently stacked with CoQ10, since the two work on different parts of the same mitochondrial-energy pathway. See our Best CoQ10 Supplement UK guide if you're building a stack.
• The evidence base is smaller and more preliminary than established ingredients like CoQ10 or creatine; treat claims about energy, mood and cognition as promising rather than settled.
• Trials measuring cognition and mitochondrial markers ran 6 to 12 weeks; don't expect a fast, noticeable effect.

How We Choose

For PQQ specifically, the single biggest factor is which raw ingredient a product actually uses. We checked whether each product names a traceable branded form (MGCPQQ/BioPQQ or PureQQ) or an unbranded generic disodium salt, whether the daily dose matches the 20mg used in the human trials and assessed by EFSA, how much manufacturing transparency and third-party testing the brand discloses, and how each product's value compares against the other five here.

Hepatica PQQ 20mg (MGCPQQ®)

Best Overall — Verified MGCPQQ

based on 79 Amazon UK reviews (4.4★), adjusted for formulation quality

What We Love About the Traceable Formula

Hepatica states plainly on the listing that this is MGCPQQ, the well-characterised, traceable branded form of PQQ, rather than a generic disodium salt with no named source. That single detail puts it ahead of most of the competition here, because MGCPQQ is close kin to BioPQQ, the exact fermentation-derived ingredient used in the Japanese cognitive and mitochondrial studies behind PQQ's reputation. It's a single-ingredient formula too, with no added blend to dilute the dose or the claim.

Traceable MGCPQQ: All The Details

Each vegan capsule delivers a measured 20mg of PQQ as branded MGCPQQ, matching both the dose used in the published human trials and the maximum level assessed as safe by the European Food Safety Authority.² The product is manufactured in a certified facility and checked by an independent third-party lab for purity, potency and label accuracy, which is more verification than most unbranded competitors offer. The pack runs to 60 capsules, a two-month supply at one a day, and the capsules are free from gluten, GMOs and unnecessary additives.

Aenutri PQQ+ Enhanced (MGCPQQ® with Q10)

Best for Pairing with CoQ10

based on 47 Amazon UK reviews (4.7★), adjusted for formulation quality

Why the CoQ10 Combination Stands Out

This one leans directly into the pairing most people ask about: PQQ alongside CoQ10 in a single capsule, rather than juggling two separate bottles. Both ingredients touch different parts of the mitochondrial energy pathway, so combining them is a common approach among people building a broader cellular-energy stack. If you already take our Best CoQ10 Supplement UK picks and were considering adding PQQ on top, this saves a step.

Patented MGCPQQ with CoQ10: All The Details

One capsule provides 20mg of MGCPQQ, described on the label as patented and over 99% pure, alongside 30mg of coenzyme Q10 as a supporting cofactor for energy metabolism. MGCPQQ is the same branded ingredient assessed and approved as a novel food by the European Food Safety Authority for use in food supplements.² The German manufacturer states the formula is laboratory tested, vegan and free from genetic engineering, with 60 capsules covering a two-month supply at one a day.

Health Thru Nutrition PQQ 20mg (PureQQ)

Most-Reviewed Pick

based on 2017 Amazon UK reviews (4.6★), adjusted for formulation quality

A Different Branded Ingredient, Not a Generic One

With well over 2,000 reviews, this is by a wide margin the most-purchased PQQ product on Amazon UK, and it isn't an unbranded product either. It uses PureQQ, a named, FDA GRAS-notified branded ingredient manufactured by chemical synthesis rather than bacterial fermentation. That's worth being precise about: PureQQ is still traceable and independently developed, but it isn't the same raw material used in the Japanese human trials discussed throughout this guide, which relied on the fermentation-derived form. Buyers wanting the largest track record of verified purchases will land here; buyers wanting the ingredient tied directly to the published cognitive studies should look at the MGCPQQ options above instead.

PureQQ Capsules: All The Details

Each capsule delivers 20mg of PQQ as PureQQ, in a formula certified vegan by the Vegan Society and stated to be non-GMO and gluten-free. The pack contains 120 capsules, a four-month supply at one a day, which undercuts the smaller 60-capsule branded options on a cost-per-month basis. Health Thru Nutrition doesn't publish a third-party certificate of analysis on the listing itself, so take the purity claim as the manufacturer's own.

Toniiq PQQ 20mg Lab Tested

Best Batch-Tested Unbranded Option

based on 210 Amazon UK reviews (4.5★), adjusted for formulation quality

Where This One Sits in the Lineup

Toniiq doesn't name a branded raw material here, so this sits in the generic tier alongside the two budget picks below rather than with the MGCPQQ or PureQQ products. What separates it from those two is manufacturing process: Toniiq states each batch is tested for quality and purity both during and after production, in a GMP-certified US facility, and it's built up a respectable 210 reviews on the UK site along the way.

Batch-Tested Purity: All The Details

Each capsule provides a concentrated 20mg dose of PQQ, with 120 capsules per jar giving a four-month supply at one a day. There's no named branded ingredient or published independent certificate of analysis, so the purity claims rest on the manufacturer's own internal testing rather than third-party verification. It's a reasonable middle-ground pick if you want a well-reviewed, competitively priced product without paying the premium that a certified branded ingredient commands.

Fitimins PQQ 20mg (Disodium Salt)

Best UK-Made Budget Pick

based on 20 Amazon UK reviews (4.9★), adjusted for formulation quality

Honest About What It Is

Fitimins doesn't dress this up as anything more than it is: plain PQQ disodium salt, manufactured in the UK, at the standard 20mg dose. It carries the highest star rating in this entire comparison, though on a fairly small review base, so treat that figure as encouraging rather than conclusive. For anyone who wants UK manufacturing and doesn't mind skipping a branded raw material to keep the cost down, it's a straightforward option.

UK-Made Disodium Salt: All The Details

One capsule provides 20mg of PQQ as the disodium salt, the standard chemical form used across most of the supplement market regardless of brand. The 120-capsule pouch covers four months at one a day. Fitimins states the product is vegan, GMO-free and manufactured in the UK, though there's no independent third-party certificate published alongside the listing, and no branded ingredient name to trace the raw material back to a specific manufacturer.

Balance Nutrition PQQ 20mg (Disodium Salt)

Simplest Label, Best Bulk Value

based on 36 Amazon UK reviews (4.2★), adjusted for formulation quality

A No-Frills Bulk Pack

Balance Nutrition takes the same approach as Fitimins above: transparent labelling of the disodium salt form, no proprietary blend, and a large capsule count for the price. The listing states a purity above 99% for the raw material itself, and the formula avoids artificial colours, flavours and preservatives, with a plant-based capsule shell rather than gelatin. It won't appeal to anyone specifically chasing a regulator-reviewed branded ingredient, but as a straightforward bulk option it does what it says.

Bulk Disodium Salt: All The Details

Each capsule contains 20mg of PQQ as the disodium salt, stated at over 99% purity, in a vegetarian-friendly HPMC capsule shell. The 120-capsule pouch runs to a four-month supply at one a day, packaged to minimise waste. As with Fitimins, there's no independent certificate of analysis published and no named branded raw material, so this sits at the same evidence tier: likely the same underlying chemical, just without the traceability that MGCPQQ or PureQQ provide.

Safety and Side Effects

PQQ's safety record is reassuring as far as it goes, even though the human trial base is small. The European Food Safety Authority reviewed PQQ disodium salt (trade name BioPQQ) as a novel food and concluded it was safe for healthy adults at up to 20mg per day, specifically excluding pregnant and breastfeeding women from that assessment.² A separate GLP-compliant toxicology programme on a different branded PQQ disodium salt found no evidence of systemic toxicity, mutagenicity or genotoxicity across acute and 90-day sub-chronic studies in animals, at doses far above typical human supplement amounts.³ In the human cognitive trial discussed below, researchers reported no abnormal blood, urinary or physical examination findings across 12 weeks of daily use.⁴

That said, published long-term human safety data beyond a few months doesn't yet exist, which is typical for a newer ingredient with a small trial base. If you're pregnant, breastfeeding, or on prescription medication, check with a GP before starting, and don't exceed the 20mg daily dose that the EFSA opinion and the human trials are actually based on, regardless of what a label might otherwise suggest.

Best PQQ Supplement FAQ

What is PQQ and how is it different from CoQ10?

PQQ (pyrroloquinoline quinone) is a small redox-active compound that acts as an antioxidant and cellular cofactor. In cell studies, it activates the CREB and PGC-1alpha signalling pathway that triggers mitochondrial biogenesis, meaning it prompts cells to build new mitochondria.¹ CoQ10 works differently: it's a component of the electron transport chain inside the mitochondria you already have, supporting the energy-production process itself rather than the creation of new mitochondria. The two are frequently taken together for that reason. See our Best CoQ10 Supplement UK guide for a full breakdown of ubiquinone versus ubiquinol.

What does the human research actually show?

It's a smaller and more preliminary picture than more established ingredients. A 12-week randomised trial in 41 healthy elderly adults taking 20mg of BioPQQ daily found improved selective attention on the Stroop test and increased prefrontal blood flow, though the lead researcher was affiliated with the ingredient's manufacturer.⁴ A more recent six-week trial in 34 older adults with mild cognitive impairment found a PQQ-containing formula improved a cognitive orientation measure and raised brain oxygenation, describing the results as "promising" rather than conclusive given the small sample.⁵ In an exercise study, 20mg daily of PQQ increased a mitochondrial biogenesis marker (PGC-1alpha protein) after six weeks of endurance training, but produced no measurable improvement in actual aerobic performance over training alone.⁶ Together, these paint PQQ as biologically plausible and safe, with early human signals, but not yet backed by the kind of large, independent trial base that ingredients like creatine or CoQ10 have.

Is PQQ proven to boost energy or exercise performance?

Not directly. The mitochondrial biogenesis mechanism is well established in cell and animal research, and human trials show PQQ can shift biological markers linked to that process (like PGC-1alpha protein levels).⁶ But the one controlled human trial that specifically measured exercise performance found no significant improvement over placebo, despite the marker changes.⁶ Treat "more energy" as a plausible, mechanism-based claim rather than a proven outcome.

How should I choose between branded and generic PQQ?

Check which raw ingredient the label actually names. MGCPQQ (also marketed as BioPQQ) is fermentation-derived and the ingredient closest to what was used in the Japanese human trials, and it's the one form that's been formally assessed as safe by EFSA at the 20mg dose.² PureQQ is a different, chemically-synthesised branded ingredient that's traceable and FDA GRAS-notified but wasn't used in those specific trials. A generic "PQQ disodium salt" with no named source may well be chemically similar, but you're relying on the seller's own purity claim rather than independent verification.

What dose of PQQ should I take?

20mg per day is both the dose used across the human trials discussed above and the maximum level EFSA assessed as safe.² Every product in this comparison sticks to that same 20mg daily serving, which is a useful sanity check: there's no published human evidence supporting higher doses, so more expensive "high-strength" claims beyond 20mg aren't backed by anything in the current research.

How long does it take to notice an effect?

The human trials ran six to twelve weeks and measured objective markers like cognitive test scores, brain oxygenation and biochemical mitochondrial markers, not day-to-day subjective energy.⁴⁵⁶ That's a realistic timeframe to expect results on, if any appear at all; this isn't a fast-acting stimulant.

Is PQQ safe, and does it have side effects?

Generally yes, based on what's been published so far. See Safety and Side Effects above for the full picture, including the EFSA safety opinion and toxicology data.

Can I take PQQ alongside mushroom supplements or CoQ10?

Yes. There's no known interaction with mushroom extracts such as cordyceps or reishi, which are traditionally used for energy and immune support through different mechanisms. Stacking with CoQ10 is common and mechanistically sensible, since the two act on different parts of the mitochondrial energy pathway; our Best CoQ10 Supplement UK guide covers ubiquinone and ubiquinol options if you want to build that combination yourself, or the Aenutri product above already combines both in one capsule.

The Best PQQ Supplement for You

If you want the ingredient most closely tied to the published human research, Hepatica's MGCPQQ formula or Aenutri's combined MGCPQQ-and-CoQ10 capsule are the most defensible picks, and Aenutri is the obvious choice if you're already planning to stack the two anyway. Health Thru Nutrition's PureQQ product has by far the deepest track record of verified UK buyers, even though it's a different branded ingredient made by a different process. If budget is the priority, Fitimins and Balance Nutrition both offer honest, no-frills disodium salt formulas at a lower cost per month, and Toniiq sits in between with independent batch testing but no named branded source. Whichever you pick, keep expectations calibrated to the evidence: PQQ is a promising, biologically plausible addition to a mitochondrial-support routine, not a proven, heavily-studied ingredient on the level of CoQ10 or creatine just yet.
