Gundry Olive Oil: An Honest Review and Comparison

By Yusuf Elsayed, Founder of Sidr & Stone · Last updated 5 June 2026

If you've looked into Gundry olive oil, you've probably met it through Dr. Steven Gundry himself — the heart surgeon turned author whose name is on the bottle. Behind the marketing sits a genuinely serious product: Gundry MD Polyphenol-Rich Olive Oil is an organic, cold-pressed, extra virgin oil from Morocco, made specifically to be high in polyphenols. So the honest question for a buyer isn't really whether it's a good oil — it is — but what its high-polyphenol promise actually means, what's worth weighing before you buy, and how it compares with another genuinely high-quality oil. This review looks at what Gundry olive oil gets right, what to keep in mind, and how it stacks up against a single-estate cold-pressed olive oil from the same country, made a different way.

The Short Answer

  • Gundry olive oil is Gundry MD Polyphenol-Rich Olive Oil, the extra virgin oil sold by Dr. Steven Gundry's wellness brand.
  • It does the important things right: organic, cold-pressed, extra virgin, sourced from Moroccan olives and made specifically to be high in polyphenols.
  • Its headline is polyphenol content — the brand reports "up to 30x" the hydroxytyrosol of many conventional oils, attributed to the stress of growing in a harsh desert climate.
  • It's third-party tested and has won an industry award, both genuine quality signals.
  • It's a US direct-to-consumer brand, so for UK and EU buyers it usually means import shipping, import pricing, and less convenient availability.
  • It sits firmly in the premium tier, and the price reflects the brand and the doctor's name as well as the oil.
  • Sidr & Stone's answer is also a Moroccan oil — but a single-estate, rain-fed, unfiltered, cold-pressed olive oil from one named grove outside Marrakech, a different route to a genuinely fresh, polyphenol-rich oil.

Who Is Gundry MD?

Gundry MD is the wellness brand founded by Dr. Steven Gundry, a former cardiac surgeon best known for his books on diet and gut health. The brand sells a range of supplements and foods directly to consumers, and its Polyphenol-Rich Olive Oil is one of its flagship products. The oil is organic, cold-pressed, extra virgin, and sourced from olives grown in Morocco.

The whole pitch of the oil is built around one idea: polyphenols. These are the natural antioxidant compounds in olive oil — hydroxytyrosol chief among them — that give a good extra virgin its bitterness and peppery catch, and that much of the research interest in olive oil centres on. Gundry MD's argument is that olives grown under environmental stress produce more of them, and the brand sources from a harsh Moroccan desert climate for exactly that reason. If you're in the United States, the oil is widely available direct from the brand. For buyers elsewhere, it's an import — which matters more than it sounds, as we'll come to.

What Gundry Olive Oil Gets Right

It's worth being clear and fair: Gundry olive oil gets the fundamentals right, and the brand has put real thought into quality. A reader comparing it with a typical supermarket blend is comparing two genuinely different things.

  • Organic, cold-pressed, extra virgin. The three things that actually matter at the production stage are all there — the only grade and method that reliably preserve flavour and polyphenols.
  • A deliberate focus on polyphenols. Sourcing from a harsh desert climate, where olive trees produce more protective compounds, is a sound and well-understood way to raise polyphenol content. This is a real strategy, not a marketing line.
  • A reported polyphenol figure. The brand states "up to 30x" the hydroxytyrosol of many conventional oils. Putting a number on polyphenols — and a high one — is more transparency than most olive oil brands offer.
  • Third-party tested. The oil is independently tested for quality, which is a genuine reassurance and the right thing to do.
  • Independent recognition. It has won a quality award, which is an external signal on top of the brand's own claims.

None of these are flourishes. They are the things that make an olive oil worth buying, and on each of them Gundry delivers. If you're in the US and want a high-polyphenol oil from a brand that tests its product, it's an easy oil to recommend.

What's Worth Weighing Before You Buy

None of what follows is a fault — it's context that helps you decide whether Gundry olive oil is the right choice for your situation.

Understand the "up to 30x" framing. The figure compares the oil with "many conventional oils," which are often low-polyphenol to begin with — so a large multiple is easier to reach than it first sounds. It's a genuine quality signal that the oil is high in polyphenols; it's just worth reading as "much higher than ordinary supermarket oil" rather than as a precise, fixed measurement of every bottle.

It's a US brand. For buyers in the UK and EU, that usually means import shipping, import pricing, customs, and less reliable availability than a domestically or regionally fulfilled oil. The oil doesn't change; the practicality of buying it does.

It's firmly premium, and it's a personality brand. Part of what you pay for is Dr. Gundry's name and the marketing around it. That can be perfectly worth it if the brand's approach resonates with you — just worth recognising for what it is. As with any oil sold within a broader wellness programme, it's wise to judge the oil on the oil, and to treat health claims about diet and supplements with the same caution you would anywhere.

What Actually Makes an Olive Oil Worth Buying

Whoever makes it, a quality olive oil comes down to the same short list of signals — and they're all knowable without a trained palate.

  • Extra virgin grade, stated plainly on the label.
  • Freshness, shown by a recent harvest date rather than a distant best-before date alone.
  • A specific named origin — an estate or a defined region, not "product of more than one country".
  • Cold extraction below 27°C, which protects the polyphenols and aromatics.
  • Dark glass or tin, to shield the oil from light.
  • The taste itself: genuine extra virgin oil is fruity, with a real bitterness and a peppery catch at the back of the throat — those are the marks of polyphenols, not defects.

Gundry meets most of this list, which is why it's a good oil. For a fuller walkthrough of each signal, see our guide to choosing a quality olive oil. Once you know the signals, you can judge any oil on its merits — Gundry's, ours, or a bottle in front of you on a shelf.

Why Sidr & Stone

Here's a point of honest common ground: like Gundry, our olive oil is Moroccan. Morocco's climate genuinely does encourage polyphenol-rich olives, and we're not going to pretend that origin is ours alone. Where we differ is the route. Gundry is a polyphenol-maximised oil sold through a large US wellness brand; ours is a single-estate oil from one named, family-owned grove on the plains outside Marrakech, sold direct with fulfilment on three continents.

  • Extra virgin grade — the only grade worth buying for flavour and polyphenols.
  • Single-estate origin — one named, family-owned grove outside Marrakech, Morocco; not a multi-farm or multi-region blend.
  • Cold-pressed within hours of harvest — extraction while the fruit is still fresh, to protect aroma and polyphenols.
  • Single-harvest small batch — a fresh, seasonal oil meant to be enjoyed during its first year.
  • Unfiltered — retaining the full polyphenol load present at pressing; a little natural sediment is normal.
  • Rain-fed and organically grown — no irrigation, no synthetic fertilisers, pesticides, or herbicides.
  • Dark glass packaging — protecting the oil from light.
  • Halal certified, with no additives of any kind.
  • 10% of profits to charity, as with every Sidr & Stone product.
  • A global brand with fulfilment in the UK, EU, and US.

In fairness, Gundry publishes a polyphenol figure and third-party tests its oil, and we won't pretend otherwise — that is a real strength. Our first harvest is a limited single-harvest batch and we have not yet published our own lab figures, so we'd rather point to what is verifiable: single-estate Moroccan, rain-fed, organically grown, cold-pressed within hours, and unfiltered. We won't tell you Sidr & Stone is "the best olive oil" — that's exactly the sort of claim this review is sceptical of. The first harvest is available to reserve now, with the first oil expected late 2026.

Frequently Asked Questions

Is Gundry olive oil good?

Yes — genuinely. Gundry MD Polyphenol-Rich Olive Oil is organic, cold-pressed, extra virgin, sourced from Moroccan olives, made to be high in polyphenols, and third-party tested. On the things that actually determine olive oil quality, it delivers.

Where is Gundry olive oil from?

Morocco. The brand sources from olives grown in a harsh Moroccan desert climate, on the basis that environmental stress pushes the trees to produce more polyphenols. The oil is then cold-pressed and bottled as organic extra virgin.

What does "polyphenol-rich" actually mean?

Polyphenols are the natural antioxidant compounds in olive oil — hydroxytyrosol most notably — responsible for much of its bitterness, its peppery catch, and the research interest around it. A polyphenol-rich oil simply has more of them, which generally means a fresher, more robustly flavoured oil made from well-grown olives.

Can you buy Gundry olive oil in the UK?

Gundry MD is a US brand, so for UK and EU buyers it generally means importing — with import shipping, import pricing, and less reliable availability than a domestically or regionally fulfilled oil. The oil is the same; the convenience and cost of getting it are not.

Is the "30x more polyphenols" claim accurate?

It's a comparison with "many conventional oils," which tend to be low in polyphenols to begin with, so a high multiple is easier to reach than it sounds. Read it as "much higher than ordinary supermarket oil," which is a genuine quality signal, rather than as a fixed figure for every bottle.

Is Gundry olive oil worth the price?

It's a premium oil, and part of the premium reflects the brand and Dr. Gundry's name as well as the oil. If the brand's approach appeals to you, it can be well worth it. If you mainly want the oil itself, it's worth comparing against other genuinely high-quality oils on the core signals rather than on marketing alone.

What should I look for in any olive oil?

Extra virgin grade, a recent harvest date, a specific named origin, a cold-pressed or cold-extraction declaration, and dark glass or tin packaging. When you taste it, look for fruity, bitter, and peppery — not bland or rancid. An oil meeting most of these is very likely a quality oil.

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

Gundry olive oil is a genuinely good product. It's organic, cold-pressed, extra virgin, sourced from Moroccan olives for their polyphenols, third-party tested, and award-winning — and it's wrapped in the marketing of a well-known wellness brand. If you're in the US and that appeals to you, it's an easy recommendation, and nothing in this review is meant to take that away.

The honest point of a review like this is that the things separating a very good oil from a mediocre one are knowable: grade, freshness, origin, cold extraction, packaging, and taste. Once you can read those signals, you can buy well from whichever brand suits you — and you're no longer paying for marketing you can't verify.

Our single-estate cold-pressed organic olive oil from Marrakech is, like Gundry's, a Moroccan oil — but a single-estate, rain-fed, organically grown, unfiltered one from a single named grove, in dark glass, with fulfilment in the UK, EU, and US. The first harvest, a limited single-harvest batch, is available to reserve now, with the first oil expected late 2026.
