Before you read a word
Why trust a site you just found?
We grade the evidence
Strong human trials, one small trial, animal research, or tradition. You see the grade before you read the claim. Most sites never tell you the difference.
We publish the nulls
The big 2022 meta-analysis found sea buckthorn did nothing for blood sugar, blood pressure, or body weight. That is on our cholesterol page, in plain sight. Honest negatives are how a site earns trust.
We show our work
Every article lists its sources with PubMed links. Our scoring and review methods are public. If we earn a commission, you see that too, right where the link is.
How we grade the evidence
Every health claim on this site carries one of four grades, shown before you read the claim. If a page says sea buckthorn helps with something, the badge tells you how much weight that actually deserves.
- Strong human evidence
Several human trials, or a meta-analysis, pointing the same way.
Example on this site: Blood lipids
- Moderate human evidence
One decent human trial, or a few small ones. Promising, not settled.
Example on this site: Dry eye, skin hydration
- Preliminary evidence (animal or lab research)
Animal or laboratory work only. Nothing tested in people yet.
Example on this site: Most cancer claims
- Traditional use (no clinical trials yet)
Centuries of use behind it, no clinical trial in front of it.
Example on this site: Wound care, digestion

Frequently asked questions
What is sea buckthorn good for?
The best-supported effect is on blood lipids: a 2022 meta-analysis of 15 randomised trials found sea buckthorn lowered triglycerides, total cholesterol and LDL, and raised HDL. Smaller single trials support dry eye and skin hydration. The same meta-analysis found no significant effect on blood sugar, blood pressure or body weight, which rules out most of the claims made in supplement marketing.
Is sea buckthorn safe to take every day?
For most healthy adults, yes, at the doses used in trials, which run roughly 2 to 3 grams of oil a day. The important exception is anticoagulant medication: one small human study found sea buckthorn oil reduced platelet aggregation, so anyone on blood thinners or facing surgery should talk to a doctor first. Our safety section covers pregnancy, children, pets and drug interactions separately.
Is SeaBuckthornWorld independent?
Yes. No brand sponsors this site, pays for coverage, or sees a page before it is published. We earn affiliate commissions on some outbound product links, which is disclosed on every page where those links appear, and commissions are not allowed to influence a product score.
How do you decide what evidence to trust?
Every health claim on the site carries one of four evidence grades, from strong human trials down to traditional use with no trials at all. We publish negative results as prominently as positive ones, cite a PubMed link for every research claim, and flag studies that have been retracted rather than quietly removing them.
Where does sea buckthorn actually grow?
Hippophae rhamnoides is native to a broad band across Eurasia, from the coasts of northern and western Europe through Russia and Mongolia to the Himalayas and northern China. China accounts for the large majority of world production. It is also cultivated in Canada and, at small scale, in the United States.
Who writes this
SeaBuckthornWorld is written by a small editorial team that covers one plant and nothing else. No brand sponsors the site, pays for placement, or sees a page before it goes live. When a study is behind a paywall, we read the paper, not the press release — and if we could only get the abstract, the page says so.
- IndependenceNo sponsored posts, no paid reviews, no brand approval
- CorrectionsErrors are fixed in place and noted. We flag retracted studies rather than quietly deleting them
- Medical reviewSeat open — we are recruiting a registered dietitian. Until one is named, no page here claims medical review
