The best sea buckthorn oil for most people is an organic, CO2-extracted berry oil or seed-and-berry blend from a brand that names the plant part on the label. Our top pick is SeabuckWonders’ organic berry oil, our highest-scoring brand, at about $0.60 a day for 1 ml (SeabuckWonders says it is CO2 extracted and USDA organic), and its Omega-7 Complete softgels are the best value at $0.75 for two. Skip anything that does not tell you whether it came from the berry or the seed.

1. SeabuckWonders Berry Oil: best overall
SeabuckWonders Organic Sea Buckthorn Berry Oil, 1.76 fl oz (52 ml)
Best overallWhy it wins. SeabuckWonders is our top-scoring brand at 9.1, and this bottle is sold as an organic berry oil in a dropper. It’s also the cheapest of our picks at the 2 g the dry-eye trial used, about $1.30 a day against $1.50 for four Omega-7 Complete softgels. At the label’s 1 ml serving, a lighter day, the 52 ml bottle works out near $0.60, against $0.75 for two softgels.
What we do not love. The berry oil is strongly colored and stains. This is a kitchen-counter oil, not a travel companion. SeabuckWonders says its dropper-bottle oils are USDA Certified Organic and Non-GMO Project Verified and that it uses supercritical CO2 extraction. Neither page names a certifier or links a certificate. The product page shows a supplement panel for a 1 ml serving that prints palmitoleic acid (omega-7) at 32 to 38%. We can’t date that panel, and the NIH label database holds no record for this bottle. If convenience matters more than price, the softgels below are the better daily habit.
Best for: anyone who wants liquid berry oil at the lowest cost per day of the three picks here and will actually use it daily.
2. SeabuckWonders Omega-7 Complete: best value
SeabuckWonders Omega-7 Complete, 120 softgels
Best valueWhy it wins. This is a proper blend, not a label trick: each 1,000 mg serving is 800 mg organic berry oil (32 to 38% palmitoleic acid, printed on the supplement facts and in NIH label record 206214) plus 200 mg seed oil. The dry-eye trial’s oil was a seed-and-pulp blend extracted with supercritical CO2, the same kind of oil. We couldn’t read the trial’s blend ratio, so we can’t say this one matches it. At $0.75 a day from the 120-count bottle, it is the best value among the softgels we scored.
What we do not love. The capsule is kosher beef gelatin, so it is not vegan. If that matters to you, see the vegan pick in our capsules guide.
Best for: daily supplementers who want a berry-and-seed blend with no measuring at a fair cost per day.
3. SIBU Organic Sea Berry Seed Oil: best pure seed oil
SIBU Organic Sea Berry Seed Oil, 30 ml
Best seed oilWhy it made the list. Sometimes seed oil is exactly what you want: lighter, pale, rich in omega-3 and 6, and friendlier on acne-prone skin. SIBU’s page says it is organic and CO2 extracted and lists one ingredient, 100% pure sea buckthorn seed oil. SIBU’s FAQ says it does not purify its oils.
What we do not love. You are paying berry-oil money for an oil with almost no omega-7. SIBU’s FAQ says seed oil is best for topical use, has properties useful when consumed as well, and has virtually no omega-7. Its page for this bottle prints no omega-7 figure, and the NIH label database holds no label for this oil. That page tells you to apply a few drops to the skin and gives no serving to swallow, so the $0.83 a day is our arithmetic at 1 ml, not a serving SIBU states. Read our seed oil vs berry oil breakdown before deciding this is what you need.
The Ordinary Sea Buckthorn Fruit Oil: a topical oil
The Ordinary 100% Organic Virgin Sea-Buckthorn Fruit Oil
Topical, not yet scoredWhy it made the list. The product’s name calls it a 100% organic virgin fruit oil, so it is the single-ingredient topical option here. We haven’t read the maker’s page, so we can’t tell you its price, its certifier or how it was extracted. We couldn’t find this oil on The Ordinary’s own store on 10 October 2026, so it may be discontinued. Check the listing before you buy.
What we do not love. It is a skincare product, not a food supplement. Do not take it by mouth. For internal use pick one of the options above. It will also tint your face orange if you overdo it.
How we chose
We started from every sea buckthorn oil we could find a label or an ingredients line and a retailer price for, then gave each one its brand’s score from the published rubric: purity and sourcing (30%), fatty acid profile (25%), third-party testing (20%), value (15%), and transparency (10%). Brands that hid the plant part, the species, or the extraction method lost points no matter how pretty the bottle was. Two types never made the list at all: unnamed-origin bulk oils on marketplaces, and any blend that leads with cheaper carrier oils like sunflower.
The scores lean on documents rather than vibes, which is the same standard the rest of the site runs on. How we research sets out where our evidence grades come from and why a brand-funded study still gets labelled as one, and it is worth two minutes before you weigh any ranking on this page, ours included.
If you take blood thinners, are pregnant or nursing, or have surgery planned, read our safety notes and talk to your doctor before dosing.
What to look for on the label
- The plant part. Berry, pulp, or fruit oil means omega-7. Seed oil means omega-3 and 6. “Sea buckthorn oil” alone means ask.
- The species. Hippophae rhamnoides is the one the research used.
- The extraction. Supercritical CO2 preserves the fatty acids best. Cold pressed is the acceptable second. Avoid solvent-extracted oils.
- Organic certification. Sea buckthorn concentrates what it grows in, good and bad.
Common oil-buying mistakes
- The carrier-cut blend. Sunflower or olive oil leading the ingredient list means a diluted bottle at an undiluted price. A blend without ratios is a no.
- The bulk no-name jug. Big anonymous marketplace bottles offer no species, no extraction, and no recourse. Cheap oil you cannot verify is not cheap.
- The bulk ingredient. Some makers sell fruit oil in bulk sizes for small-batch products. SIBU’s starts at 2 oz for $24.95, about $0.42 a day at 1 ml against about $0.60 for our top pick, but it is sold as an ingredient with no serving size on its page, so we haven’t scored it.
- The giant bottle “for value.” Oil oxidizes after opening, so a bottle sized for six months of use delivers three good months and three rancid ones. Buy for two to three months ahead.
- Swallowing the cosmetic bottle. Cosmetic-grade oils are not held to food standards, which is why our topical pick carries a do-not-eat note. Internal use means a food-grade bottle from the picks above.
The 60-second decision path
- Daily oral use, liquid at the lowest cost per day among the three picks here: pick one, the liquid overall winner.
- Daily oral use, best value with zero measuring: the softgel pick, and the capsules guide for more options.
- Topical use only: The Ordinary’s fruit oil once you have checked its price, and expect tint at full strength.
- Unsure which oil type your goal needs: the seed oil vs berry oil breakdown before any cart.
Storage: what changes after opening
The printed best-by date assumes a sealed bottle. Once opened, the oxidation clock starts, and the unsaturated fatty acids mapped on the fatty acid profile page are the first casualties. Liquid oil goes in the fridge, cap tight, dropper wiped clean so nothing travels back into the bottle. Softgels get a cool, dry cabinet, never a steamy bathroom. Match bottle size to your real pace using the dosage page: at 1 gram a day a 52 ml bottle lasts about seven weeks, and at the dry-eye trial’s 2 grams about three and a half, which is close to the right size. Any oil that smells like crayons or old paint is done, whatever the date says. The oil nutrition page covers the absorption side: take your dose with a meal that contains some fat, or part of what you stored so carefully never gets absorbed.
Who should skip the liquid form
Liquid oil is the value winner and still wrong for some buyers. Skip it if the earthy taste or the measuring routine will kill the habit, because softgels exist precisely for you. Skip it if your kitchen runs warm and fridge space is tight, because oxidation will tax every degree. Skip it for travel-heavy lives, where a leaking dropper bottle ruins a bag and a softgel bottle does not. And skip it for purely topical goals, where a cosmetic-grade fruit oil can do the same job.
Where these statements come from
The organic, CO2 and omega-7 statements above are the makers’ own. Here is the page or record behind each one.
- Organic and Non-GMO: SeabuckWonders’ FAQ says its dropper-bottle oils are USDA Certified Organic and Non-GMO Project Verified. It also says the Omega-7 Complete capsules are beef gelatin because it has no source for high-volume organic-certified beef gelatin capsules, and that they are kosher certified by Tablet K.
- CO2 extraction: SeabuckWonders’ quality page and omega-7 page say it uses supercritical CO2 extraction. The FAQ page doesn’t mention it.
- Organic oils: the maker’s organic page says its pure sea buckthorn oils have USDA Organic Certification.
- Berry oil panel: the berry oil product page shows a supplement panel for a 1 ml serving that prints palmitoleic acid (omega-7) at 32 to 38%.
- Omega-7 Complete label: NIH label record 206214 is a dated snapshot of the registered label, entered in August 2019, with the 800 mg berry oil, the 200 mg seed oil and the 32 to 38% figure.
- Non-GMO Project: the Non-GMO Project’s product finder lists SeabuckWonders’ Organic Himalayan Sea Buckthorn Berry Oil.
- SIBU’s seed oil: SIBU’s product page says it is organic and CO2 extracted with one ingredient. SIBU’s FAQ says seed oil is best for topical use and that it does not purify its oils.
Frequently asked questions
What is the best sea buckthorn oil to take?
For internal use, we rate SeabuckWonders' organic berry oil highest, at about $0.60 a day for the label's 1 ml serving, with its Omega-7 Complete softgels the best value at $0.75 a day for two. Look for the plant part on the label, organic certification, and CO2 extraction.
Is it better to take sea buckthorn oil or capsules?
Liquid oil costs less per gram, but many people dislike the taste and the staining. Capsules cost more per day and are far more convenient. The studies used both, so pick the form you will actually take every day.
How much sea buckthorn oil should I take per day?
The benefit trials used 0.5 to 3 grams per day, and only the dry-eye trial is documented as split across meals. In volume that is roughly 0.55 to 3.3 ml of liquid oil (about a tenth to two-thirds of a teaspoon) or 1 to 6 softgels depending on the product. The costs on this page are for 1 ml or 2 softgels, which sit inside that range but aren't a dose any trial we cite gave. The 2 g the dry-eye trial used costs about $1.30 as liquid berry oil and $1.50 as softgels.
Does sea buckthorn oil need to be refrigerated?
After opening, yes, or at minimum a cool, dark cabinet. The unsaturated fatty acids that make the oil valuable are the same ones that oxidize, and cold, dark, and sealed slows that down. If it starts to smell like crayons, it is done.
