This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Independent external anchors
Public sources on this same product, unrelated to NO1GEVITY. NIH DSLD is the US government's registered label database (shown verbatim). SuppCo.com is a separate, unaffiliated commercial site with no partnership or data-sharing arrangement with us. NO1GEVITY scores are computed independently of both.
What others say, with a source hierarchy
We treat external opinion very differently depending on where it comes from. Tier A is our strongest signal. Tier C is background sentiment only. Tier Rejected is what we excluded, listed openly so you can see what we discarded.
These reviews are aggregated from third-party sources, not written by NO1GEVITY. Each entry shows its source, retrieval date, and whether the source has an affiliate or paid relationship. We do not edit reviews to change their meaning. Disclosure policy.
Tier A
Independent deep reviews, lab tests, certificates of analysis
Our strongest external evidence. Long-form independent reviews, physical-product lab work, and third-party certifications.
Examine.com, PQQ page
No affiliate relationship

Independent corroboration that PQQ's human evidence base remains preliminary, consistent with this dossier's tier-4 classification of the core Nakano 2012 study.
Finding: Examine's evidence grading for PQQ on human cognitive/energy outcomes is generally characterized as limited/low-confidence, reflecting the small number of human trials and their methodological limitations (small samples, open-label designs).
How we use it: Used as independent confirmation of overall evidence-strength characterization.
Tier C
Aggregated sentiment (Trustpilot, Reddit)
Mood indicator only. We never use aggregate stars as evidence of efficacy.
supplabel.com, Life Extension PQQ Caps label data
No affiliate relationship
Not a paid placement
Unconfirmed discontinuation signal from a lower-tier aggregator source, not independently verified against the primär vendor page's live status.
Finding: Indicated this exact SKU's label data reflects the 'last available version' with an april 2026 update note suggesting possible discontinuation.
How we use it: Flagged as an unverified signal in the unverified section rather than treated as confirmed fact, given the lower reliability tier of this source type.
Vår sammanfattning
Life Extension's PQQ Caps deliver 20 mg of PQQ disodium salt (as the named branded ingredient BioPQQ) per capsule, a dose that matches both human pilot studies identified in this research pass. The foundational study behind the product's positioning, Nakano et al. (2012), reported improvements in fatigue, sleep, and mood in a small group of middle-aged and elderly subjects, but it was open-label with no placebo control, which is a material limitation given how commonly subjective wellbeing measures respond to expectation effects in unblinded designs. A more recent 2023 controlled trial at the same 20 mg dose reported cognitive improvements in older adults, a somewhat stronger design, though this dossier could not fully verify its blinding methodology from available sources. The mitochondrial-biogenesis mechanism cited in marketing is grounded in legitimate but purely preclinical/animal research; no human trial in this product's dose range has directly measured mitochondrial biogenesis as an outcome. PQQ disodium salt carries multiple FDA GRAS food-ingredient notifications supporting a reasonable general safety profile. A lower-tier retail data source flagged a possible recent discontinuation of this exact SKU, which this dossier could not independently confirm.
Bevisning, what actually backs this product
Longevity brands rarely test their exact finished product. We separate what's tested from what's inferred.
Strongest evidence tier
Tier 3Ingredient RCT (matching dose)
3 studies mapped
Tier 3Ingredient RCT (matching dose)
Effects of PQQ supplementation on cognitive function in healthy older adults
ingredient-levelpeer-reviewed
Reported improvements on select cognitive performance measures versus comparison group.
This trial does appear to be a controlled design (improvement over the Nakano 2012 open-label study) and matches this product's exact 20 mg dose, making it the strongest single piece of evidence for this specific product; however, this dossier could not fully verify from the available excerpt whether this trial was placebokontrollerad and double-blinded, or the exact sample size, flagged as a verification gap.
Conflicts: Not fully disclosed in available excerpt
Tier 4Ingredient RCT (different dose)
Effect of Pyrroloquinoline Quinone (PQQ) on Mental Status of Middle-Aged and Elderly Subjects
ingredient-levelpeer-reviewed
Subjects reported improvements in fatigue, sleep quality, and mood; changes correlated with reductions in cortisol awakening response and other stress-related biomarkers.
CRITICAL LIMITATION FLAG: this is the exact study and exact dose (20 mg/day) that Life Extension's product positioning is built around, but it is a small (n=17), OPEN-LABEL pilot study with no placebo control group. Without blinding or a placebo arm, expectation and reporting bias cannot be ruled out as explanations for the reported subjective improvements (fatigue, sleep, mood). This is meaningfully weaker evidence than a placebokontrollerad trial despite matching this product's exact dose, and should not be described to consumers as dubbelblind or placebokontrollerad evidence.
Conflicts: Not fully disclosed in the available excerpt; PQQ ingredient-industry funding ties are common in this small research literature and were not ruled out
Tier 5Mechanistic / animal / marketing
PQQ and mitochondrial biogenesis, mechanistic and animal evidence
ingredient-levelpeer-reviewed
PQQ has been shown in preclinical models to activate PGC-1alpha and related pathways associated with mitochondrial biogenesis.
This is the underlying mechanistic rationale for PQQ's mitochondrial-support marketing claims; it is legitimate preclinical science but does not by itself establish that oral 20 mg/day PQQ produces measurable mitochondrial biogenesis in humans.
Conflicts: None identified

Partially Supported
“Supports mental clarity, mood, and reduced fatigue in aging adults”
The 20 mg dose matches both human studies located (Nakano et al. 2012, and a 2023 Food & Function RCT), both of which reported improvements in fatigue/mood/sleep or cognitive measures. However, the more foundational and directly product-dose-matched Nakano 2012 study was open-label with no placebo control (n=17), a significant limitation that undermines confidence the effect is not partly attributable to expectation or reporting bias. The 2023 RCT is stronger in design but this dossier could not fully verify its blinding/placebo status from available excerpts.
Unsupported At The Human-Outcome Level
“Supports mitochondrial energy production and biogenesis”
The mitochondrial-biogenesis mechanism is supported by legitimate preclinical/animal research showing PQQ activates PGC-1alpha-related pathways, but this dossier found no human trial directly measuring mitochondrial biogenesis or ATP production as an outcome of oral PQQ supplementation at this product's dose. The marketing claim extrapolates from animal mechanistic data to a human energy-production benefit that has not been directly demonstrated in a human trial.
Supported
“GRAS-recognized, generally safe ingredient”
Multiple independent FDA GRAS notifications (GRN 590, 641, 694, 709) for PQQ disodium salt exist on file, with toxicology data showing no genotoxicity and a high rodent NOAEL (~400 mg/kg/day), which is a reasonable basis for a general safety claim at typical supplemental doses.

What we could not verify
We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.
- A third-party retail-data source (supplabel.com) indicated this exact 20 mg PQQ SKU may have been discontinued as of an april 2026 label-data update; this dossier could not independently confirm current live retail/discontinuation status and treats this as an unresolved flag rather than a confirmed fact.
- Whether the 2023 Food & Function RCT (20 mg/day, 12 weeks) was placebokontrollerad and double-blinded, and its exact sample size, could not be fully verified from the excerpt reviewed.
- The exact conflict-of-interest disclosures (ingredient-supplier funding) for both the Nakano 2012 and 2023 Food & Function studies were not fully verified in this research pass.
- Whether this specific PQQ product was named in Life Extension's februari 2017 FDA warning letter (which cited disease claims on other lifeextension.com produkter) was not confirmed.
- No independent third-party lab test (ConsumerLab, Labdoor) confirming this SKU's actual PQQ potency was located.
Important to know
PQQPQQ is very expensive to synthesise, so cheap produkter may under-deliver. Look for third-party COA.
Redaktionellt notes
20mg PQQ matches the trial dose used in the main human trial (Nakano 2012, fatigue/QoL improvements at 20mg/day); note a lower-dose 10mg BioPQQ variant is also sold at retailers like Target, so confirm mg strength before comparing prices.
