Dr Gundry Olive Oil: How It Compares on Origin and Polyphenols
If you have come across Dr Gundry olive oil — sold as Gundry MD Polyphenol-Rich Olive Oil, and searched for as everything from "Gundry olive oil" to "Gundry MD olive oil reviews" — you have probably met the headline claim first: a Moroccan extra virgin oil with "up to 30x" more hydroxytyrosol than many conventional olive oils. It is one of the most talked-about bottles in the high-polyphenol category, sold by Gundry MD, the wellness brand founded by the former cardiothoracic surgeon Dr Steven Gundry. The questions buyers actually ask are simpler than the marketing: is it legit, what is verified versus claimed, is it worth it, and what are the alternatives? This review answers all four, honestly and on the facts.
For our own oil, see our cold-pressed extra virgin Marrakech olive oil.
The Short Answer
- Dr Gundry olive oil is Gundry MD Polyphenol-Rich Olive Oil: a single-ingredient organic extra virgin olive oil from desert olive groves in Morocco, in an 8.5 fl oz (about 250 ml) bottle.
- On the brand's own pages it is first cold-pressed and described as third-party tested, and its Amazon listing sells it as USDA organic. Those are real strengths, and we say so plainly.
- "Up to 30x more hydroxytyrosol than many conventional olive oils" is an "up to" claim against an unnamed baseline, not a per-batch figure. Two analyses commissioned by Olive Oil Times in 2021 put the oil at 561–612 mg/kg total phenols — high, but a measured number, not a multiple.
- It is a direct-to-consumer US brand, sold through its own website and Amazon, often in bundles and subscriptions; for UK and EU buyers it is normally an import.
- Genuine alternatives exist — another Moroccan oil, and Greek and Cypriot high-phenolic oils that publish a figure — and we compare them by name below, on each brand's own statements.
- Sidr & Stone's olive oil is also Moroccan, from our own single-estate farm outside Marrakech: extra virgin, rain-fed, organically grown (not yet certified — certification is in progress), cold-pressed and unfiltered.
Who Is Dr Gundry, and What Is Gundry MD Olive Oil?
Dr Steven Gundry is a former cardiothoracic surgeon best known for his diet books, including The Plant Paradox, and for his supplement company, Gundry MD. The brand sells a broad range of wellness products direct to consumers, and its Polyphenol-Rich Olive Oil is one of its most visible. The pitch is built around polyphenols — the plant compounds in olive oil that a substantial body of research has found genuinely interesting.
What is actually in the bottle
On the product facts, as published on Gundry MD's own pages, the oil holds up well:
- One ingredient — "organic extra virgin olive oil — first cold press", nothing added.
- Moroccan desert-grown olives — the brand describes "the harsh desert olive groves of Morocco", and argues that plants growing under environmental stress produce more of their protective compounds.
- Described as third-party tested — "third-party tested to ensure the best quality", in the brand's words; we found no certificate published alongside the bottle.
- 8.5 fl oz bottle in dark glass — roughly 250 ml, which matters when you compare value.
The brand describes the taste as "bold, peppery, and slightly bitter" — what a polyphenol-forward oil is like, not a fault, though it takes adjusting to after a mild supermarket oil. Where the picture gets more nuanced is the headline number.
The Polyphenol Claim: What "Up to 30 Times More" Actually Means
Polyphenols are the reason this oil exists as a product. They are antioxidant compounds — hydroxytyrosol, oleuropein, oleocanthal and tyrosol among them — studied most closely in the context of the Mediterranean diet. For the full picture, see our guide to olive oil polyphenols and the compounds that actually matter.
What the evidence does and does not say
The EU's authorised health claim, under Commission Regulation (EU) No 432/2012, reads "olive oil polyphenols contribute to the protection of blood lipids from oxidative stress", and may be used only for an oil containing at least 5 mg of hydroxytyrosol and its derivatives per 20 g, with the effect obtained at 20 g a day. That condition is written around one fraction of the oil, so a total-phenols figure like the one below is a different measurement and does not, on its own, show that an oil meets it. The strongest trial evidence sits behind the diet pattern rather than any bottle: PREDIMED (Estruch et al., New England Journal of Medicine, 2018), a randomised trial in 7,447 Spanish adults at high cardiovascular risk, found fewer major cardiovascular events with a Mediterranean diet supplemented with extra virgin olive oil — evidence for a whole diet, republished after protocol deviations in randomisation, and not a test of Gundry MD's oil or ours.
Reading the "up to 30x" line
Gundry MD's own wording is "up to 30x more hydroxytyrosol than many conventional olive oils". Any "up to" claim describes a ceiling, not an average — and "conventional olive oil" is a moving baseline, since a tired, oxidised supermarket oil can be very low in polyphenols. Against a weak enough comparison, large multiples are easy to reach.
The independent 2021 figure
The number worth knowing is 561–612 mg/kg. Olive Oil Times commissioned two analyses of Gundry MD's oil, published by Curtis Cord in February 2021, which found total phenolic content in that range — a high-polyphenol oil by any fair standard, and we are happy to say so, but a measured figure rather than a marketing multiple. The same article reported that "an internationally-certified taste panel leader found the Gundry sample from the most recent harvest to be lampante" — the lowest grade of virgin olive oil, not fit to be sold for eating until it has been refined. That concerned one sample, assessed in 2021; it does not establish the status of present batches, the brand now describes its oil as third-party tested, and we have not tested current batches ourselves. The takeaway is not "30 times" but that polyphenol content is real, variable, and best judged by a published figure.
Is Dr Gundry Olive Oil Legit? Reviews, Complaints and the Value Question
The most common question we see is some version of "is Dr Gundry olive oil legit?" On the product, yes: it is a real organic extra virgin olive oil from Morocco, with an independently measured polyphenol figure in the high range. The reservations people raise in reviews and complaints are about everything around the oil. It is sold direct to consumers — through the brand's own website and Amazon, usually as multi-bottle bundles and subscribe-and-save offers — so you are paying for the oil and for the machine that sells it, and the bottle is a small one at 8.5 fl oz. We do not state prices; check the current cost directly.
Two more things are worth weighing. Gundry MD is a US brand, so for UK and EU buyers it usually means import shipping, customs and less reliable availability than a regionally fulfilled oil. And part of what you pay for is Dr Gundry's name and programme — reasonable if the approach resonates with you, but worth recognising. Gundry MD's listings make a range of wellness claims for the oil; we do not echo them, and would encourage the same caution with any olive oil sold on health outcomes rather than on what can be verified.
Origin and Method: Both Moroccan, but Not the Same Story
Dr Gundry olive oil and Sidr & Stone olive oil are both Moroccan. The desert-stress argument Gundry MD makes is a plausible one — water stress is one of several factors, alongside cultivar, ripeness at picking and how quickly the fruit is pressed, that the olive-chemistry literature associates with phenolic content. It is an argument, though, not a per-bottle measurement.
The difference is in the specifics. Gundry MD describes desert olive groves in Morocco without naming an estate. Sidr & Stone's oil comes from one named source: our own family farm on the plains outside Marrakech, where we control the whole process from tree to bottle. The trees are rain-fed and organically grown, without synthetic pesticides, herbicides or fertilisers, and the fruit is picked when it is ready. The oil is extra virgin, cold-pressed and bottled unfiltered, so it may show a little natural sediment — normal, and a sign of minimal processing.
Two things we concede
First, Gundry MD's oil is sold as USDA organic; ours is grown organically on land we farm ourselves, but it is not yet certified organic — certification is in progress — and we would rather say so than imply a certificate we do not hold. Second, we have not yet published a laboratory polyphenol figure for our oil, so we will not quote one. What we offer instead is single-estate traceability — see why single-estate origin and traceability matter — and a small single-harvest batch whose source we can name exactly.
Gundry MD vs Sidr & Stone, side by side
| Attribute | Gundry MD Polyphenol-Rich Olive Oil | Sidr & Stone Marrakech Olive Oil |
|---|---|---|
| Origin | Morocco — "harsh desert olive groves"; specific estate not named | Single-estate: our own farm on the plains outside Marrakech, Morocco |
| Grade and extraction | Organic extra virgin, first cold press; "cold-pressed soon after harvest" | Extra virgin, cold-pressed, unfiltered |
| Organic status | Sold as USDA organic (brand's Amazon listing) | Organically grown on our own farm; not yet certified — certification in progress |
| Polyphenols | "Up to 30x more hydroxytyrosol than many conventional olive oils" (brand); 561–612 mg/kg total phenols in two 2021 analyses commissioned by Olive Oil Times | No laboratory figure published yet — we do not quote one |
| Independent testing | Brand states third-party tested; no certificate published | Not yet published |
| Harvest | Timing not stated on the pages we read | Limited single-harvest batch, picked when the fruit is ready |
| Bottle | 8.5 fl oz (about 250 ml), dark glass | 500 ml dark glass |
| How it is sold | US direct-to-consumer and Amazon; bundles and subscriptions; an import for UK and EU buyers | Direct; pre-order; fulfilment in the UK, EU and US |
Read fairly, the two oils lead in different places. Gundry MD's oil is sold as certified organic and has an independently measured polyphenol figure on the record, which we credit openly. Sidr & Stone offers a named single estate we farm ourselves, cold-pressing, an unfiltered oil, a larger bottle, and fulfilment that spares UK and EU buyers an import.
Dr Gundry Olive Oil Alternatives
If you are looking for a Dr Gundry olive oil alternative, start with what you actually want from it: the same Moroccan origin, a published polyphenol figure, a larger bottle, or simply an oil you can buy without importing. The table below uses each brand's own published statements as of September 2026. The figures are brand-stated, may cover different compounds, methods, harvests and laboratories, and cannot be compared directly — this is not a ranking. We have not tested any of these oils ourselves.
| Brand | Origin | Organic status (as stated) | Polyphenol figure as published (measure, harvest, method) | Who reports it | Bottle; where sold |
|---|---|---|---|---|---|
| Gundry MD Polyphenol-Rich Olive Oil | Morocco, desert groves; estate not named | USDA organic (Amazon listing) | "Up to 30x" hydroxytyrosol vs many conventional oils (no figure or method given); 561–612 mg/kg total phenols in two analyses, 2021 | Claim: the brand. Figure: independent analyses commissioned by Olive Oil Times | 8.5 fl oz (~250 ml); brand website and Amazon (US) |
| Atlas Olive Oils "Desert Miracle" | Morocco, estate about 150 km from Casablanca towards Marrakech | "Organic certified" | None published; described as "polyphenol rich" | — | 250 ml / 500 ml; the brand's own websites |
| Olivea | Messinia, Greece (Koroneiki) | Not stated on the pages we read | 1,000+ mg/kg (Ultra High Phenolic) and 500+ mg/kg (Everyday) polyphenols; harvest not stated; HPLC and NMR named as test methods | The brand; "every batch" third-party tested, laboratory not named | Size not stated; US direct, UK via Healf |
| Oleaphen | Cyprus | Not stated on the pages we read | 2,236 mg/kg polyphenols, 2025 harvest, by LC-MS/MS | The brand; "independent certified laboratories", not named | Size not stated; the brand's website |
| Sidr & Stone Marrakech Olive Oil | Morocco, our own single-estate farm outside Marrakech | Organically grown; not yet certified (certification in progress) | None published yet — we do not quote a figure | — | 500 ml; direct, pre-order, fulfilment in the UK, EU and US |
Read on their own terms, each leads somewhere different. Olivea and Oleaphen publish figures and describe third-party or independent testing, though neither names its laboratory; Atlas states organic certification and shares our Moroccan origin, without a published figure; Gundry MD sits between, with an independent figure on the record but no named estate. Sidr & Stone's is the only oil here pressed from a farm the seller owns and runs — extra virgin, rain-fed, organically grown, cold-pressed and unfiltered. Against Gundry MD we concede the certificate and the lab figure, and would rather earn your order on what we can show you today.
Our cold-pressed extra virgin Marrakech olive oil is available to pre-order now, with estimated shipping from November 2026. It is a limited single-harvest batch, so quantities are finite.
How to Choose a Quality Olive Oil
Whichever brand you are weighing up, the criteria that actually matter are the same, and none of them is the boldest number on the front of the bottle:
- Origin you can name. "Product of more than one country" tells you little; a single estate or a named region tells you a great deal.
- A recent harvest. Polyphenols and flavour fade with time, so a clear harvest date matters more than a best-before.
- Genuine cold pressing. Extra virgin and unrefined — extracted mechanically, below 27°C, without heat or chemistry.
- Dark glass. Light degrades polyphenols, so protective packaging is not just presentation.
- What the producer will verify. A published polyphenol figure, a certification, or clear sourcing — something checkable rather than a superlative.
- The taste itself. Genuine extra virgin oil is fruity, with real bitterness and a peppery catch — the marks of polyphenols, not defects.
For a fuller walkthrough, see our guide to choosing a quality olive oil, and for how to check a brand's phenolic number, our piece on high phenolic olive oil and verifying the figure on the bottle. Judge an oil on what its maker is willing to show you, not on the size of the claim.
Why Sidr & Stone
Our olive oil is built on facts a reader can check rather than claims they have to take on faith.
- Single-estate — our own family farm on the plains outside Marrakech, Morocco; the whole process, from tree to bottle, under our control; no blending across origins.
- Extra virgin — cold-pressed, unfiltered, unrefined; may show natural sediment.
- Rain-fed — no irrigation; the trees take what the season gives.
- Organically grown — no synthetic fertilisers, pesticides or herbicides; not yet certified, with certification in progress.
- Single harvest — a small, limited batch, picked when the fruit is ready; once the current batch is gone, it is gone until the next harvest.
- 100% natural — a single ingredient, nothing added.
- 500 ml dark glass with a gold label — protective packaging against light.
- 10% of profits given to charity.
- Fulfilment in the UK, EU and US.
We will not tell you Sidr & Stone is the best olive oil — that would be the very claim this article warns against. What we will say is that our oil is single-estate Moroccan from a farm we run ourselves, rain-fed, organically grown and cold-pressed — and that the evidence of that care is in the taste, the colour and the small single-harvest batch.
Frequently Asked Questions
What is Dr Gundry olive oil?
It is Gundry MD Polyphenol-Rich Olive Oil: a single-ingredient organic extra virgin olive oil from Moroccan desert groves, in 8.5 fl oz bottles. "Gundry olive oil", "Dr Gundry olive oil" and "Gundry MD olive oil" are the same product.
Is Dr Gundry olive oil really 30 times higher in polyphenols?
"Up to 30x" is the brand's ceiling, set against conventional oils that can be very low in polyphenols. Two 2021 analyses commissioned by Olive Oil Times found 561–612 mg/kg total phenols: high, but a measured figure, not a multiple.
Is Dr Gundry olive oil legit, and is it worth it?
Yes, it is a genuine organic extra virgin oil with an independently measured polyphenol figure. Whether it is worth it depends on how you weigh the small bottle, the bundle-and-subscription selling and, outside the US, the cost of importing it.
Where is Dr Gundry olive oil from, and what is in it?
Morocco. The brand describes desert olive groves without naming a specific estate. The only ingredient listed is organic extra virgin olive oil, first cold press.
Why does Gundry MD olive oil taste bitter?
Bitterness and a peppery throat-catch come from polyphenols and are typical of robust extra virgin oils. The brand itself describes the taste as "bold, peppery, and slightly bitter" — a feature of the style, not a fault.
Where can I buy Gundry MD olive oil, and can I get it in the UK?
From Gundry MD's own website and Amazon in the US, often as bundles or subscriptions. For UK and EU buyers it is usually an import, so check shipping, customs and current terms before ordering.
What is the best Dr Gundry olive oil alternative?
It depends on what you want. For a published polyphenol figure, Olivea and Oleaphen state one, each measured its own way; for Moroccan origin, Atlas and Sidr & Stone are named-estate options. Ours is single-estate, organically grown and on pre-order.
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
Dr Gundry olive oil is a serious entry in the high-polyphenol category: a single-ingredient, organic, first cold-pressed Moroccan extra virgin oil with an independently measured polyphenol figure behind it. The parts worth holding lightly are the "up to 30x" line — a multiple against an unnamed baseline tells you less than a measured figure — and the bundles, subscriptions and, for many readers, the import that come with the way it is sold.
The better habit, with any olive oil, is to ask what the producer will actually show you: where the olives grew, how the oil was pressed, and what is verified. Judge the bottle on that — whether it is Gundry MD's, one of the alternatives above, or ours.
Sidr & Stone's answer is our own farm on the plains outside Marrakech: a rain-fed, organically grown single-harvest batch, cold-pressed and bottled unfiltered. Our cold-pressed extra virgin Marrakech olive oil is available to pre-order, with estimated shipping from November 2026 and fulfilment in the UK, EU and US.
Our extra virgin olive oil is grown organically on our own single-estate farm on the plains outside Marrakech: we control every step from tree to bottle, and no synthetic pesticides, herbicides or fertilisers are used. It is not yet certified organic — certification is in progress, and we will publish it as soon as it comes through.
