C60 Olive Oil: What the Evidence Actually Shows
C60 olive oil is sold on one of the boldest promises in the supplement trade: that a solution of carbon-60 fullerene dissolved in olive oil can slow down ageing. The promise traces almost entirely to a single paper published in 2012, in which rats given the solution lived markedly longer than the animals they were compared with. That paper is real, it is still in the literature, and it is also one of the most heavily misread studies on the internet. This article does what the search results for C60 olive oil mostly do not — it names the study, reports what two later attempts to reproduce it found, and sets out the current legal position for C60 as a food ingredient. Then it looks honestly at what ordinary olive oil is.
For our own oil, see our cold-pressed organic Marrakech olive oil — a single-estate Moroccan extra virgin oil with nothing dissolved in it.
The Short Answer
- C60 olive oil is a suspension of buckminsterfullerene — a hollow, sixty-atom carbon molecule — in olive oil, which happens to be one of the few edible solvents that will dissolve it.
- The lifespan claim rests on one paper: Baati T, Bourasset F, Gharbi N, Njim L, Abderrabba M, Kerkeni A, Szwarc H and Moussa F, Biomaterials 2012;33(19):4936–4946 (PMID 22498298). Its stated aim was to establish the chronic toxicity of C60, not to test longevity.
- That paper carries a published corrigendum by the same authors: Biomaterials 2012;33(26):6292–6294. It has not been retracted; the corrigendum sits on the PubMed record as an erratum notice.
- Two independent mouse studies published in 2021 both failed to find a lifespan benefit. One of them, Grohn et al. in GeroScience, additionally found that C60 in olive oil forms toxic species under ordinary room light.
- C60 is not an authorised novel food in Great Britain. A search of the Food Standards Agency's GB novel food authorisations register on 21 August 2026 returned no entry for "fullerene" or "C60". It does not appear in the European Commission's Novel Food status Catalogue either.
- There is no human trial of C60 for ageing, longevity or any other outcome. Every claim you will read about it in people is extrapolated from rodents.
- Sidr & Stone sells plain olive oil and nothing else in the bottle. We think that is the honest place to stand on this topic, and we say so plainly rather than pretending to neutrality we do not have.
What C60 Olive Oil Is
C60 olive oil is extra virgin or refined olive oil in which carbon-60 fullerene has been dissolved, usually at low concentrations and then filtered to remove undissolved particles. C60 is a hollow sphere of sixty carbon atoms, discovered in 1985. It is almost insoluble in water and only sparingly soluble in oils, which is why olive oil became the standard vehicle for it.
The choice of olive oil was not aesthetic. Braun and colleagues published a short paper in Fullerenes, Nanotubes and Carbon Nanostructures in 2007 titled "Olive oil as a biocompatible solvent for pristine C60", and that work is cited in the 2012 rat study itself. Olive oil is simply one of the few edible liquids that will hold the molecule in solution at a workable concentration.
Commercially, the product is sold in small dark bottles, often 100ml, sometimes with a dropper or applicator, and often alongside versions made with MCT oil or avocado oil. Vendors typically describe their material as "research grade". That phrase has no regulatory meaning in a food context.
The 2012 Rat Study — and the Two Studies That Followed
The paper behind the entire category is Baati and colleagues, published in Biomaterials in June 2012, volume 33, issue 19, pages 4936 to 4946 (DOI 10.1016/j.biomaterials.2012.03.036, PMID 22498298). Its title is "The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene", and its abstract is explicit about the purpose: more than twenty-five years after C60's discovery, "the in vivo fate and the chronic effects of this fullerene remain unknown", and the authors set out to address that. The lifespan finding emerged from a chronic toxicity design. It was not the question the study was built to answer.
Three things about that paper are worth holding in mind. It is small. It has never been independently reproduced. And it carries a corrigendum published by the same eight authors three months later, in Biomaterials 2012;33(26):6292–6294 (DOI 10.1016/j.biomaterials.2012.05.023). We checked the PubMed record for PMID 22498298 on 21 August 2026: it lists "Erratum in Biomaterials. 2012 Sep;33(26):6292-4" and carries no retraction notice. The paper stands, corrected. Anyone who tells you it was retracted is wrong; anyone who tells you the record is entirely clean has not looked.
What happened next is the part the vendor pages leave out. In 2021, two separate groups published lifespan work on C60 in mice.
| Study | Animal | What it set out to do | What it found |
|---|---|---|---|
| Baati et al., Biomaterials 2012;33(19):4936–4946 (PMID 22498298) | Rats | Establish chronic toxicity and in vivo fate of C60 dissolved in olive oil | No chronic toxicity; treated animals lived substantially longer than controls. Carries a 2012 corrigendum. Never independently replicated. |
| Grohn et al., GeroScience 2021;43(2):579–591 (PMID 33123847) | Mice | Test commercial and in-house C60 olive oil for purity, light stability and lifespan effect | No lifespan or health span benefit. Marked differences between online vendors' products. Light-dependent toxicity in under two weeks. |
| Shytikov et al., Rejuvenation Research 2021;24(5):345–353 (PMID 33849306) | CBA/Ca mice | Long-term C60 treatment, lifespan and health status | C60 mice outlived the olive-oil-treated group, but matched the water-treated group — pointing to the vehicle, not the C60. |
The Shytikov result is the one that deserves a second read. In that study, C60-treated mice did live longer than mice given olive oil alone — but they lived no longer than mice given plain water. The abstract puts it plainly: "Treatment of mice with C60 fullerenes resulted in an increased lifespan of males and females compared with the olive oil-treated animals. The lifespan of C60-treated mice was similar to the mice treated with water." When your positive result disappears the moment you add a water control, the finding is about the control group.
Light, Purity, and What Is Actually in the Bottle
The single most practical finding in the recent literature is not about ageing at all. Grohn and colleagues, publishing in GeroScience in 2021, reported that pristine C60 in olive oil "does form toxic species that can cause significant morbidity and mortality in mice in under 2 weeks when exposed to light levels consistent with ambient light". Not laboratory ultraviolet. Room light.
The same paper obtained C60 olive oil from a sample of online vendors and found, in the authors' words, "marked discrepancies in appearance, impurity profile, concentration, and activity relative to pristine C60-OO formulated in-house". That is a plain statement that what is sold under this name varies, and that a buyer holding a bottle has no practical way to know which version they have.
This is a general problem with any ingredient outside a regulated framework, and it is worth being fair about it. It is not evidence that any particular vendor is careless. It is evidence that the category has no compositional standard to be held to — no equivalent of the free acidity, peroxide value and sensory panel that define extra virgin olive oil, and no equivalent of the polyphenol threshold that European law attaches to a specific health claim. Where there is no standard, there is nothing to verify against.
Is C60 Legal to Sell as a Food?
This is the question buyers ask least and should ask first. We checked the primary registers on 21 August 2026 rather than relying on secondary sources, and the position is clearer than the marketing suggests.
In Great Britain, the Food Standards Agency maintains a public register of authorised novel foods. Searching that register for "fullerene" returns no results; searching for "C60" returns no results. The register was last updated on 31 March 2026. As a control, searching the same register for "astaxanthin" returns the authorised entry NOVEL-17, so the search itself works.
In the European Union, Regulation (EU) 2015/2283 defines a novel food to include, at Article 3(2)(a)(i), "food with a new or intentionally modified molecular structure, where that structure was not used as, or in, a food within the Union before 15 May 1997", and at Article 3(2)(a)(viii), "food consisting of engineered nanomaterials". Article 6(2) of the same Regulation states that "Only novel foods authorised and included in the Union list may be placed on the market within the Union". C60 does not appear in the European Commission's Novel Food status Catalogue — the F section of that catalogue runs from Fucus vesiculosus through "Fulvic acid" to Fusarium venenatum with no fullerene entry.
| Jurisdiction | Source checked, 21 August 2026 | Result |
|---|---|---|
| Great Britain | FSA GB novel food authorisations register (updated 31 March 2026) | No entry for "fullerene" or "C60" |
| European Union | European Commission Novel Food status Catalogue | No fullerene or C60 entry in the catalogue |
| European Union | Regulation (EU) 2015/2283, Articles 3(2)(a)(i), 3(2)(a)(viii) and 6(2) | Engineered nanomaterials and novel molecular structures fall within the novel food definition; only foods on the Union list may be marketed |
The honest reading is this: C60 has no food authorisation in Great Britain or the European Union, and the Regulation's own definitions bring it squarely within the category that requires one. That is a regulatory fact, not a safety verdict. It does not mean the substance has been assessed and rejected. It means it has not been through the process.
The Objections Worth Taking Seriously
"You sell olive oil, so of course you are sceptical." That is a fair thing to notice, and we would rather name it than have you notice it silently. We do sell olive oil. We also have no product to sell you in this category and no interest in pretending the 2012 paper does not exist — it does, it is interesting, and we have cited it in full. What we will not do is describe a rat study as if it applied to you.
"Absence of replication is not disproof." Correct, and it is a point that is often made carelessly in the other direction. But we are past the stage of mere absence. Two groups tried, in mice, in 2021, and neither found a benefit — and one of the two found the apparent benefit dissolved when a water control was added. That is a different and stronger situation than a finding simply sitting unreplicated.
"Regulators are slow. Not being authorised does not mean unsafe." Also true. Plenty of perfectly ordinary foods are unauthorised in the novel food sense purely because nobody has paid for the dossier. The reason it matters here is narrower: authorisation is the only mechanism that produces a public compositional specification. Without one, the Grohn finding about vendor-to-vendor variation has no remedy.
What Plain Olive Oil Actually Offers
It would be easy to end this article with a shrug. It is more useful to say what the boring option gives you, because it is not nothing.
Extra virgin olive oil is one of the very few foods with an authorised health claim in European law, and the wording is precise. Under Commission Regulation (EU) No 432/2012, "Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress". The conditions of use are equally precise: "The claim may be used only for olive oil which contains at least 5 mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) per 20 g of olive oil. In order to bear the claim information shall be given to the consumer that the beneficial effect is obtained with a daily intake of 20 g of olive oil." That is one authorised claim, with a measurable threshold, an accredited analytical method behind it, and a stated daily intake. It is the opposite of an unverifiable promise.
The same regulation carries a second claim relevant to olive oil, for oleic acid: "Replacing saturated fats in the diet with unsaturated fats contributes to the maintenance of normal blood cholesterol levels. Oleic acid is an unsaturated fat." Olive oil is predominantly oleic acid. For a fuller treatment of the compounds involved, see our guide to olive oil polyphenols, and for how to check a polyphenol figure on a label, see high phenolic olive oil.
| Question | C60 olive oil | Plain extra virgin olive oil |
|---|---|---|
| Authorised as a food ingredient in GB or the EU? | No entry found in either register | Yes — a defined food with a legal grade standard |
| Any authorised health claim? | None | Two under Regulation (EU) 432/2012, with stated conditions |
| Human trials for ageing? | None | None for ageing specifically; a large dietary-pattern literature exists |
| Compositional standard a buyer can check against? | None | Free acidity, peroxide value, UV absorbance, sensory panel |
| Light sensitivity | Toxic species formed under ambient light in mice (Grohn 2021) | Polyphenols degrade with light and time; dark glass and cool storage help |
None of that makes olive oil a treatment for anything. It is a food. What it does have is a floor you can stand on: a grade defined in law, a claim with a number attached, and a set of measurements any competent laboratory can run. For the practical version of that, see our guide to choosing a quality olive oil. If you were drawn to C60 by the idea of a concentrated daily dose in a small format, our piece on olive oil capsules covers what that form can and cannot deliver.
Why Sidr & Stone
We came to this topic the same way most readers do — someone asked us about it. The honest answer took an afternoon in the primary literature and twenty minutes in two regulators' registers, which is roughly twenty minutes more than the top search results appear to have spent. That is the whole of our claim to authority here: we looked, and we are telling you what we found.
Our own olive oil is deliberately unexciting in composition:
- Single-estate — one family-owned grove on the plains outside Marrakech, Morocco, with no blending across origins.
- Rain-fed — no irrigation; the trees take what the season gives them.
- Organically grown — no synthetic fertilisers, pesticides or herbicides. We do not hold a formal organic certificate and we do not claim one.
- Single harvest — a small batch, once a season, picked when the fruit is ready rather than when the calendar says so, which can be weeks later than neighbouring farms.
- Cold-pressed within hours of harvest — flavour, aroma and polyphenols preserved by minimising the gap between picking and pressing.
- Unfiltered extra virgin — minimally processed, and it may show natural sediment, which is normal for an unfiltered oil.
- 100% natural — one ingredient. Olive oil. Nothing dissolved in it, nothing added to it.
- Dark glass — protective packaging against light, which matters for polyphenols in any olive oil.
- Halal certified, with 10% of profits to charity as a brand-wide commitment, and fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is the best olive oil — that would be the very kind of claim this article warns against. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown, and cold-pressed within hours of harvest, and that the evidence of that care is in the taste, the colour and the size of the season's batch. Olive oil is honoured in the Prophetic Sunnah, which we write about separately in our guide to olive oil in the Quran and the Sunnah.
Frequently Asked Questions
What is C60 olive oil?
It is olive oil with carbon-60 fullerene dissolved in it, usually at low concentration. Olive oil is used because it is one of the few edible liquids that will hold the molecule in solution. It is sold as a supplement, mostly on longevity marketing.
Did C60 really double the lifespan of rats?
One 2012 paper reported a large lifespan increase in rats — Baati et al., Biomaterials 2012;33(19):4936–4946. That paper was designed as a chronic toxicity study, carries a published corrigendum from the same authors, and has never been independently reproduced.
Has anyone repeated the study?
Two groups tried in mice in 2021 and neither found a lifespan benefit. Grohn et al. in GeroScience found no benefit and light-dependent toxicity. Shytikov et al. in Rejuvenation Research found the apparent benefit vanished against a water control.
Are there any human trials of C60?
Not for ageing or longevity. A PubMed search on 21 August 2026 for fullerene trials in humans returns work on topical cosmetic fullerene and a fullerene derivative in radiation dermatitis — nothing on oral C60 in olive oil for ageing or any related outcome.
Is C60 legal to sell as a food in the UK or the EU?
C60 does not appear in the Food Standards Agency's GB novel food authorisations register or in the European Commission's Novel Food status Catalogue. Under Regulation (EU) 2015/2283, engineered nanomaterials require authorisation before being placed on the EU market.
Why does the light-exposure finding matter?
Because ambient light is not an unusual storage condition. Grohn et al. reported that C60 in olive oil forms toxic species under light levels consistent with ordinary room light, causing morbidity and mortality in mice within two weeks. Dark glass and cool storage are sensible for any oil.
How is Sidr & Stone's olive oil different from C60 olive oil?
Ours contains one ingredient — cold-pressed extra virgin olive oil from a single estate near Marrakech, with nothing dissolved in it. It is a food with a legal grade standard, not a supplement built around a nanomaterial that has no food authorisation.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
The idea behind C60 olive oil is genuinely appealing, and it is worth saying so without sneering. A single elegant molecule, an ordinary kitchen ingredient as its carrier, and a startling result in a real peer-reviewed journal — that is a good story, and the people buying it are not fools for finding it interesting. We found it interesting too.
The trouble is that the story has not held up. The original paper was a toxicity study with a corrigendum attached. Two attempts to reproduce the lifespan effect in mice failed, and one of them suggested the original comparison group may have been the problem. A third finding — that the product forms toxic species in room light — is the kind of thing that ought to be on every label and is on none of them. There is no human evidence at all, and no food authorisation in Great Britain or the European Union.
What is left, if you want a daily spoonful of something with actual evidence behind it, is the oil itself: a food with a defined grade, one authorised health claim with a measurable threshold, and several thousand years of use. That is a lower ceiling than "doubles lifespan". It is also a floor that does not give way.
