Bevisning gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Säkerhet caps applied after weighting.

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.

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 B

Registered dietitians and physicians, without affiliate ties

Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.

Trustpilot (lifeextension.com, brand-level, not product-specific)

No affiliate relationship Not a paid placement

Customers overwhelmingly praise product quality, effectiveness claims, delivery speed, and customer service; recurring complaints center on billing/auto-ship issues, occasional empty or damaged capsules, and inconsistent customer-service responsiveness (Life Extension replies to roughly 48-82% of negative reviews depending on region).

Finding: 4.4/5 average ('Excellent') across roughly 300-670 reviews depending on region/snapshot (308 on the primär US domain as of the juli 2026 crawl; 665-668 on the German storefront; 381-544 on Canadian/NZ storefronts)

How we use it: This is brand-level sentiment, not a review of Ageless Cell specifically, no Trustpilot reviews naming this exact product were identified. Used only as background on general order-fulfillment and customer-service reliability, not as evidence of product efficacy. Trustpilot reviews are unverified purchaser self-reports and are not a substitute for clinical evidence.

Tier C

Aggregated sentiment (Trustpilot, Reddit)

Mood indicator only. We never use aggregate stars as evidence of efficacy.

iHerb customer reviews (product page)

Has affiliate relationship Not a paid placement

Sparse, generic positive reviews typical of a retailer product page; no methodology, no blinding, no measurement of any biomarker.

Finding: Star rating and review count not fully extracted in this pass; spot-checked reviews were generically positive ('Definitely recommend giving it a try!')

How we use it: Used only to note that consumer sentiment exists and is not negative; explicitly not used as evidence of efficacy given the complete absence of methodology and the retailer's affiliate incentive to display positive reviews prominently.

Swanson Vitamins customer reviews (third-party retailer product page)

Has affiliate relationship Not a paid placement

Small sample retailer star rating with no visible methodology or verified-purchase disclosure standard comparable to Trustpilot's.

Finding: 4.3/5 stars across 43 reviews

How we use it: Directional-only; not weighted meaningfully given N=43 and lack of methodology transparency.

Vår sammanfattning

GEROPROTECT Ageless Cell is a legitimately AI-screened supplement, Life Extension's 2016 collaboration with Insilico Medicine really did use gene-expression-based computational modeling to shortlist NAC, myricetin, and EGCG as candidate 'geroprotectors' in cultured senescent human cells, and that process is documented in a peer-reviewed paper. But the product's placement next to 'senolytic' editorial content and beside Life Extension's own dasatinib/quercetin/fisetin-free 'Senolytic Activator' invites a comparison this formula cannot support: none of Ageless Cell's ingredients have been shown, in a human clinical trial at this product's doses, to clear senescent cells the way dasatinib+quercetin or fisetin have in early human trials. Individually, NAC has the best human evidence (RCTs at 600 mg/day showing reduced senescence markers in obese and older adults, versus 450 mg/day here), while myricetin and gamma-tocotrienol have only in vitro or off-dose human data, and EGCG's dose here (~100 mg/day) sits well below typical trial doses (300-400 mg/day). This is a Tier 5 (mechanistic/in vitro-only for the product's core 'senescence' claim) product with Tier 4 ingredient-level support for select individual compounds at different doses, a scientifically interesting but clinically unproven formula whose marketing language runs meaningfully ahead of what any study, including the company's own foundational research, has actually shown.

Senolytika decrease senescent cells in humans: Preliminary report from a clinical trial of Dasatinib plus Quercetin in individuals with diabetic kidney disease

Hickson LJ, Langhi Prata LGP, Bobart SA, et al. (Justice JN senior/coordinating author on the companion IPF senolytics program) · 2019 · EBioMedicine · n=9 · Dasatinib 100 mg + Quercetin 1000 mg orally, once daily for 3 consecutive days ('hit-and-run' dosing) · 3 days of dosing, biopsies at baseline and 11 days after

ingredient-levelpeer-reviewed

This is the landmark human proof-of-concept that a true senolytic drug combination (dasatinib + quercetin, D+Q) reduces measurable senescent-cell burden in human adipose tissue and skin, and lowers circulating SASP factors. This is included here specifically because it is the trial Life Extension's own marketing language ('senolytic-inspired', 'helps clear senescent cells') implicitly trades on. Ageless Cell contains neither dasatinib nor quercetin.

CRITICAL APPLICABILITY NOTE: this trial is NOT evidence for Ageless Cell. It used a prescription tyrosine-kinase inhibitor (dasatinib, sold as Sprycel) plus high-dose quercetin, an ingredient not on the Ageless Cell label at all. The only genuine senolytics with any human trial data (dasatinib+quercetin, fisetin) are absent from this formula. This entry exists to make explicit the gap between the marketing framing and the actual product contents.

Conflicts: NIH- and foundation-funded (Mayo Clinic); none disclosed related to a commercial supplement.

Tier 0No source

Senolytika in idiopathic pulmonary fibrosis: results from a first-in-human, open-label, pilot study

Justice JN, Nambiar AM, Tchkonia T, et al. · 2019 · EBioMedicine · n=14 · Dasatinib 100 mg/day + Quercetin 1250 mg/day, 3 consecutive days per week for 3 weeks · 3 weeks (intermittent dosing)

ingredient-levelpeer-reviewed

The other foundational human senolytics study (Justice et al. 2019), again using dasatinib+quercetin, showing feasibility/tolerability and early signals of physical-function improvement in a fibrotic, high senescent-burden disease population.

Same applicability gap as above: this is prescription-drug evidence for D+Q, an entirely different intervention from Ageless Cell's myricetin/NAC/EGCG/tocotrienol blend. Included to make the evidentiary contrast explicit per the research brief.

Conflicts: NIH- and foundation-funded; none disclosed related to a commercial supplement.

Tier 4Ingredient RCT (different dose)

Effects of N-acetylcysteine on aging cell and obesity complications in obese adults: a randomized, dubbelblind clinical trial

Rastgoo S, et al. · 2023 · (Iranian RCT, registered IRCT20220727055563N1) · n=40 · 600 mg/day oral NAC · 4 weeks

ingredient-levelpeer-reviewed

NAC 600 mg/day significantly reduced senescence-associated beta-galactosidase (SA-β-gal) activity and p16/IL-6 gene expression in visceral adipose tissue versus placebo, and improved several inflammatory and glycemic markers. This is genuine human RCT evidence that NAC has measurable senomorphic/anti-inflammatory activity.

Dose (600 mg/day) is close to but slightly higher than Ageless Cell's 450 mg NAC dose. Population (obese bariatric-surgery candidates) is not representative of the general healthy-aging consumer targeted by this product, and the readout is a tissue biomarker, not a functional aging outcome. This is the single strongest piece of ingredient-level human evidence in the entire formula.

Conflicts: None identified; academic/Iranian university funding via IRCT registration.

Tier 4Ingredient RCT (different dose)

Co-administration of vitamin D and N-acetylcysteine to modulate immunosenescence in older adults with vitamin D deficiency: a randomized clinical trial

Rastgoo S, et al. · 2025 · Frontiers in Immunology · n=88 · 600 mg/day NAC, co-administered with 1000 IU or 5000 IU/day vitamin D · 8 weeks

ingredient-levelpeer-reviewed

NAC co-administration further reduced p16 transcript expression in immune cells versus vitamin D alone, though most of the senescence-marker benefit tracked with the vitamin D dose rather than NAC.

Same 600 mg NAC dose as above; again in an older, at-risk (vitamin D-deficient) population, not a matched-dose isolated test of NAC in healthy adults. Supports Tier 4 classification for NAC, not higher.

Conflicts: None identified; Iranian academic/hospital funding.

Tier 4Ingredient RCT (different dose)

Myricetin bioactive effects: moving from preclinical evidence to potential clinical applications

Semwal DK, et al. (review); primär human data drawn from a 4-week RCT of 'Blueberin' (250 mg blueberry leaf extract + 50 mg myricetin, taken 3x/day) · 2020 · BMC Complementary Medicine and Therapies / cited primär literature · n=42 · 50 mg myricetin (as part of a 300 mg Blueberin blend) taken three times daily = 150 mg myricetin/day total · 4 weeks

ingredient-levelpeer-reviewed

The one placebokontrollerad human trial identifiable for myricetin found that a myricetin-containing blueberry-leaf blend significantly reduced fasting plasma glucose and several inflammatory/liver markers in type 2 diabetics.

This is the closest thing to human RCT evidence for myricetin, and the per-dose amount (50 mg) matches Ageless Cell's label, but the total daily exposure in the trial (150 mg/day, split 3x) is 3x higher than Ageless Cell's once-daily 50 mg, in a diabetic population, and measuring glycemic/inflammatory markers rather than senescence or 'anti-aging' endpoints. The authors of the parent review state plainly that clinical trial data on myricetin are 'limited' and further RCTs are 'urgently' needed.

Conflicts: Not disclosed in secondary review; primär Blueberin trial funding not verifiable from this source.

Tier 4Ingredient RCT (different dose)

Dose dependent elevation of plasma tocotrienol levels and its effect on arterial compliance and plasma total antioxidant status in healthy subjects

Rasool AH, et al. · 2006 · (pharmacology/nutrition journal, PubMed-indexed) · n=36 · Tocotrienol-rich vitamin E (TRE) at 80, 160, or 320 mg/day (mixed tocotrienol isomers, not gamma-tocotrienol alone) · 2 months

ingredient-levelpeer-reviewed

160 mg and 320 mg/day doses produced small, statistically significant reductions in aortic systolic blood pressure; no significant effect on arterial compliance, total antioxidant status (except a modest 9.2% rise at 320 mg), total cholesterol, or LDL-C.

This trial used 80-320 mg/day of mixed tocotrienols. Ageless Cell supplies only 25 mg/day of gamma-tocotrienol specifically, roughly 3-13x lower than the lowest dose tested here, and the isomer mix differs. Effects at the doses actually tested were modest and inconsistent across endpoints even before accounting for the dose gap.

Conflicts: Not disclosed in available abstract.

Tier 4Ingredient RCT (different dose)

Tocotrienol rich fraction supplementation improved lipid profile and oxidative status in healthy older adults: a randomized controlled study

Chin SF, et al. · 2011 · (nutrition journal, cited in tocotrienol.org research compendium) · 160 mg/day tocotrienol-rich fraction (TRF, mixed isomers) · 6 months

ingredient-levelpeer-reviewed

160 mg/day TRF for 6 months improved lipid profile and oxidative status markers versus placebo in healthy older adults.

Again a mixed-isomer TRF dose (160 mg/day) roughly 6x higher than Ageless Cell's 25 mg gamma-tocotrienol-specific dose. Directionally supportive of tocotrienols' cardiometabolic mechanism but not evidence for the dose actually delivered in this product.

Conflicts: Not verifiable from secondary source; original study not independently located on PubMed in this pass.

In vitro concentrations tested do not correspond to the softgel's oral doses. · Not applicable (cell culture assay)

ingredient-levelpeer-reviewed

This is the actual scientific basis for the product: Life Extension's Andrew Swick co-authored a paper with Insilico Medicine (then based at Johns Hopkins' Emerging Technology Centers) describing a gene-expression-based algorithm (GeroScope) that ranked candidate geroprotector compounds, then tested six of them in senescent human skin fibroblast cultures. NAC, myricetin, and EGCG were among the natural compounds that 'improved several senescence-associated properties' in vitro. This is legitimate mechanistic science, but it is a cell-culture screening study, not a human clinical trial of the finished capsule, or even of these compounds at oral doses.

This is the ingredient-selection paper Life Extension repeatedly cites as the scientific origin of Ageless Cell (confirmed via Insilico Medicine's own 2016 press materials). It establishes plausibility, not efficacy in humans. Andrew Swick (Life Extension's own SVP of scientific affairs) is a co-author, which is a disclosed but real conflict of interest for a paper marketed as independent AI-driven validation.

Conflicts: Co-author Andrew G. Swick was, at time of publication, Life Extension's SVP of Scientific Affairs, Discovery Research and Product Development, i.e., an employee of the company selling the resulting product.

Tier 5Mechanistic / animal / marketing

Epigallocatechin Gallate (EGCG), Cognitive Vitality for Researchers

Alzheimer's Drug Discovery Foundation (ADDF) Cognitive Vitality summary, citing multiple primär RCTs · 2024 · ADDF research summary (secondary), citing peer-reviewed primär trials · Underlying trials mostly used 300-400 mg EGCG/day (up to 800-1,200 mg/day in some); Ageless Cell's green tea extract supplies roughly 100 mg EGCG/day (223 mg extract standardized to 45% EGCG) · Ranges from 12 weeks to 18 months across cited trials

ingredient-levelpeer-reviewed

Across published human RCTs, EGCG at typical tested doses (300-400 mg/day) has shown modest effects on LDL cholesterol and some antioxidant markers, but two RCTs in multiple sclerosis at 800 mg/day found no clinical benefit, and cancer-prevention trials have not shown protective effects. No human trial has tested EGCG for 'cellular senescence' or aging outcomes directly.

Ageless Cell's EGCG dose (~100 mg/day) is at the low end of, or below, doses used in essentially all cited human RCTs (300-400+ mg/day). This ingredient's inclusion traces to the Aliper 2016 in vitro screening paper, not to any EGCG-specific human aging trial.

Conflicts: Not applicable, secondary summary source; underlying trial COIs not individually re-verified here.

Claim check, vendor claims vs. our reading of the evidence

Not medical advice. We list the strongest claims made by the brand and check each against traceable evidence.

Partial support

“"GEROPROTECT Ageless Cell uses anti-aging nutrients identified by artificial intelligence to help rejuvenate near-senescent cells and promote cellular rejuvenation and energy"”

The AI-screening claim is verifiably true and well-documented: Life Extension's own Andrew Swick co-authored the underlying 2016 Aging paper with Insilico Medicine describing the GeroScope algorithm that flagged NAC, myricetin, and EGCG (Aliper et al. 2016, PMID 27677171). However, 'helps rejuvenate near-senescent cells' describes an in vitro fibroblast-culture finding, not a demonstrated effect in a person taking the capsule. The claim conflates 'these compounds did something to cells in a dish' with 'this product does something to your cells,' which is a significant and uncited leap.

Not supported

“Implicit/adjacent 'senolytic' positioning, the product page links to an in-house 'Editor's Pick' article titled 'Senolytic Supplements: The Longevity Hack Everyone's Talking Om oss' directly beneath the Ageless Cell listing, and Life Extension markets a companion product literally named 'Senolytic Activator'”

This is the central issue flagged in the research brief. The only human clinical evidence that a compound can act as a true senolytic (selectively killing senescent cells and reducing measurable senescent-cell burden and SASP factors in humans) is for dasatinib+quercetin (Hickson/Justice et al. 2019, PMID 31542391) and, in animal/early human work, fisetin. Ageless Cell contains neither dasatinib, quercetin, nor fisetin, those compounds are reserved for Life Extension's separate 'Senolytic Activator' product. Ageless Cell's actual mechanism, per its own cited science, is 'geroprotection' (mimicking a youthful gene-expression signature in cultured cells), which is a distinct and much weaker claim than 'senolytic.' Placing senolytic editorial content directly on this product's page, without clarifying that this SKU does not contain a tested senolytic compound, is materially misleading.

Unverifiable

“"Encourages the body's healthy process for dealing with senescent [cells]"”

No human trial on this product or its exact ingredient combination measuring actual senescent-cell clearance was located. The claim is phrased vaguely enough ('encourages... healthy process') to avoid a direct efficacy claim, but no evidence, in vitro, animal, or human, was found demonstrating this specific outcome for the finished formula.

Not supported

“"Promotes organ vitality"”

No study, mechanistic, animal, or human, was identified that measured any organ-level outcome for this product or this specific ingredient combination. This is a broad wellness claim with no traceable supporting citation on the vendor page or in the underlying Insilico Medicine research.

Partial support

“"Supports a healthy inflammatory response"”

Individually, NAC (Rastgoo et al. 2023, PMID-pending/PMC10546057) has RCT evidence of reducing IL-6 and hs-CRP at 600 mg/day in obese adults, and EGCG has mechanistic anti-inflammatory activity in vitro and in animal models. No trial tested the combined formula's effect on inflammatory markers, and Ageless Cell's NAC dose (450 mg) is below the 600 mg dose that showed this effect.

Not supported

“"Promotes youthful cellular metabolism"”

This restates the mechanistic hypothesis from the Aliper 2016 in vitro screening paper (mimicking a 'young' gene-expression signature) as if it were a demonstrated outcome of taking the capsule. No human metabolic-outcome data for this product exists.

Supported

“"Formulated by a partnership between Life Extension and Insilico Medicine, Inc."”

Independently confirmed via Insilico Medicine's own 2016-2017 press releases and the peer-reviewed Aliper et al. 2016 Aging paper, which lists a Life Extension employee (Andrew Swick) as co-author (https://www.eurekalert.org/news-releases/463385, https://www.eurekalert.org/news-releases/524562, PMID 27677171). This is one of the few claims on the page that is both specific and independently verifiable.

Regelverk status

Rules change often. We record when we last verified each row. See the full regulatory timeline →

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.

No published human clinical trial exists on the finished Ageless Cell softgel itself, at its actual combined doses, every piece of supporting evidence is either an in vitro screening study (the Aliper 2016 Aging paper) or ingredient-level trials at different doses and in different (often diseased) populations.
The extract standardization of the 50 mg myricetin dose (from Myrica cerifera bark/leaf extract) is not disclosed, it is unclear what percentage of that 50 mg is actual myricetin versus other bark/leaf constituents, making exact potency verification impossible from the label alone.
No independent, product-specific lab test (ConsumerLab, Labdoor, or similar) verifying that Ageless Cell softgels actually contain the labeled amounts of NAC, myricetin, EGCG, and gamma-tocotrienol was located in this research pass.
Life Extension does not publish a public, per-batch Certificate of Analysis for this SKU; it states COAs are available 'upon request,' which this dossier was not able to independently request and verify.
The task brief's stated ingredient list (myricetin, gamma-tocotrienol, hesperetin, NAC, phenylalanine) does not match the current vendor label (Vitamin E, NAC, green tea/EGCG extract, myricetin, gamma-tocotrienol), it is unclear whether this reflects a past reformulation, a different regional SKU, or a brief-drafting error; buyers should verify the label on the specific bottle/region they are purchasing.
No data on how much elemental myricetin, EGCG, or gamma-tocotrienol actually survives softgel processing and gastrointestinal absorption was located; bioavailability of myricetin and EGCG in particular is known in the general literature to be low.

Important to know

FisetinStandard capsules have <5% absorption. Look for liposomal or with piperine.

QuercetinPlain quercetin dihydrate has poor absorption. Phytosome forms deliver 10 to 20× more into blood.

MyricetinAny mg number on a label is a guess — there is no validated human dose. Bioavailability is the weak point.

CurcuminProdukter with just 'turmeric extract' and no branded delivery system are not bioavailable. Ask for the specific bioavailability system.

In plain language

Why this scored this way

This Life Extension GEROPROTECT Ageless Cell scores 4.7, making it among the lowest-scoring produkter we track. It contains 60mg of Quercetin, which is only 12% of the 500mg trial dose with grade B evidence (promising human data, not yet comprehensive). At $15.56/day it's among the more expensive options in Senolytic.

What drives the score up

Tested by independent lab (transparency 7.5).

What drags it down

Dose-evidence score of 3.4 is below average for the site.
Overall dose is only 9% of the trial dose across ingredients.
Fisetin (45mg is 9% of the 500mg trial dose) is significantly under-dosed.
Quercetin (60mg is 12% of the 500mg trial dose) is significantly under-dosed.
Curcumin (30mg is 3% of the 1000mg trial dose) is significantly under-dosed.

Why you'd choose it

You want Quercetin from a Life Extension product.
You prioritise tested by independent lab produkter with public lab certificates.

Why you might skip it

You need a full trial dose of fisetin (this product under-doses it).
You want a cheaper option (this is $15.56/day).
You want a product that hits the full trial dose (this is at 9%).
