Sea Buckthorn Benefits
Sea buckthorn is a small orange berry from the Himalayas, and it's often sold as a superfood. Its nutrition is well documented: it's rich in vitamin C, vitamin E, carotenoids and a rare omega-7 fat. Its health benefits are less certain. The claims you'll see online (stronger immunity, a healthier heart, balanced blood sugar) come mostly from lab and animal studies, and the human trials so far are small and mixed.
This guide separates the two. It covers what's in the berry, what trials in people have actually found, and how to use the pulp.
Key Takeaways
- Sea buckthorn berries of the common subspecies contain roughly 360–400 mg of vitamin C per 100 g, well above the 65–80 mg an Indian adult needs each day.
- About 40% of the fat in the berry pulp is palmitoleic acid, an omega-7 fat that few plant foods contain.
- A 2026 review of 12 trials found no consistent effect on cholesterol, blood pressure or weight, and rated all the evidence "very low certainty". The largest trial found it did not prevent colds.
- Treat it as a nutrient-dense fruit, not a medicine.
What is sea buckthorn?
Sea buckthorn (Hippophae rhamnoides) is a thorny shrub that grows in cold, dry mountain regions. Its berries are small, bright orange and very sour. In India it's sometimes called "Leh berry", after the region where most of it grows.
Ladakh has nearly 64% of India's sea buckthorn cultivation area, and much of the crop still grows wild there (UT Ladakh Administration, December 2025). "Ladakh Sea Buckthorn" also holds a Geographical Indication (GI) tag, alongside Ladakh Pashmina and the Raktsey Karpo apricot (UT Ladakh Administration, June 2026).

What nutrients does sea buckthorn contain?
Vitamin C is the standout. Berries of the common rhamnoides subspecies contain about 360 mg per 100 g, and some Chinese varieties reach 2,500 mg (Jaśniewska & Diowksz, Antioxidants, 2021). A separate study measured about 400 mg per 100 g (Gutzeit et al., Journal of Food Science, 2008). Vitamin C levels depend on the variety and when the berries are picked, so treat these as typical figures rather than a guarantee.
| Nutrient | What the research reports |
|---|---|
| Vitamin C | About 360–400 mg per 100 g of berries (common subspecies) |
| Omega-7 (palmitoleic acid) | About 40% of the fatty acids in the pulp (Ding et al., 2019) |
| Vitamin E | Present in the berries and concentrated in the pulp oil |
| Carotenoids | β-carotene, lycopene, lutein and zeaxanthin, which give the berry its orange colour |
| Flavonoids | Mainly isorhamnetin and quercetin |
For context, the ICMR-NIN recommends 80 mg of vitamin C a day for adult men and 65 mg for adult women (ICMR-NIN, 2020). At 400 mg per 100 g, about 20 g of fresh berries would cover a day's need. Most people buy sea buckthorn as pulp or juice rather than fresh berries, though, and processing changes the numbers. See the section on forms below.
What does research show about sea buckthorn benefits?
Much less than most articles suggest. Human trials exist, but they are few, small and often test different products, from whole berries to capsules to oil. Here's what they found.
| Claimed benefit | What human trials found | Strength of evidence |
|---|---|---|
| Cholesterol and heart health | Mixed. A 2022 review saw lower cholesterol only in people whose levels were already abnormal. A 2026 review found no consistent effect. | Very low |
| Blood sugar | Small drops in fasting glucose and a lower insulin spike after a sugary meal. Too small to matter clinically. | Very low |
| Colds and immunity | No fewer or shorter colds in a 254-person trial. | No effect found |
| Digestion and constipation | One 2026 trial of a capsule extract improved bowel movements. | Early, single trial |
| Skin and eyes | The trials used sea buckthorn oil, such as an eyelid spray for dry eye, not pulp. | Not tested for pulp |
Cholesterol, blood pressure and weight
The most thorough review so far pooled 12 randomised trials with 901 adults across seven countries. It found no significant effect on total cholesterol, LDL, HDL, triglycerides, systolic blood pressure or BMI. Fasting glucose and diastolic blood pressure dropped slightly, but the authors called the changes "clinically negligible" and rated every outcome as very low certainty (Moroşan et al., Trends in Food Science & Technology, 2026). An earlier review of 15 trials was more positive about cholesterol, but only in people whose cholesterol was already high, and its results varied widely between studies (Geng et al., Phytotherapy Research, 2022).
Blood sugar
In 38 adults with impaired glucose regulation, 90 ml of sea buckthorn puree a day for five weeks lowered fasting glucose by a median of 0.14 mmol/L. The authors described it as a "slight downward trend" (Ren et al., Foods, 2021). In a separate study of 18 overweight men, adding sea buckthorn puree to a sugary meal didn't change blood glucose, but it lowered and delayed the insulin peak (Mortensen et al., European Journal of Nutrition, 2018). Neither result makes sea buckthorn a treatment for diabetes.
Colds and immunity
Sea buckthorn is often marketed for immunity because of its vitamin C. When 254 healthy adults took sea buckthorn berries or a placebo in a double-blind trial, the sea buckthorn group caught just as many colds, and they lasted just as long. Levels of CRP, a marker of inflammation, fell very slightly (Larmo et al., European Journal of Clinical Nutrition, 2008).
Digestion
The most promising recent result is for constipation. In a 2026 trial, 90 adults with chronic constipation took either a 500 mg sea buckthorn extract capsule or a placebo daily for four weeks. Bowel movements in the extract group rose from 1.5 to 2.6 a week, with no side effects reported (Morone et al., Nutrients, 2026). It's a single trial of a concentrated extract, so it doesn't tell us whether pulp has the same effect.
Pulp, juice, oil or capsules: does the form matter?
Yes, a lot. Pulp, juice, oil and capsules each keep different parts of the berry, and what sea buckthorn is used for explains how they differ. For the research, two things matter most.
Processing also affects vitamin C, which breaks down with heat and time. In one industrial study, making juice cost 5–11% of the berries' vitamin C, concentrating the juice cost 50%, and a further 11–12% was lost after seven days in the fridge (Gutzeit et al., 2008). The raw-berry figures above don't carry over directly to a bottled product, so check the nutrition panel on the pack you buy.
When a claim says "research shows sea buckthorn helps X", it's worth asking which form was studied. The dry-eye study used an oil spray on the eyelids (Larmo et al., 2019). The constipation study used capsules. Pulp has been studied mainly in the blood-sugar and cholesterol trials, where the effects were small.
How do you use sea buckthorn pulp?
Sea buckthorn pulp is very tart, so it's almost always diluted: the usual serving is 15–30 ml in a glass of water, but follow the serving size printed on your pack. A few drops of monk fruit liquid drops take the edge off the sourness without adding sugar. For recipe ideas, from sherbet to chutney, see what sea buckthorn is used for.
Our sea buckthorn pulp comes in a 500 ml bottle, and the full range is in the sea buckthorn collection. If you're new to monk fruit, what is monk fruit sweetener explains how it differs from sugar.
Who should be careful with sea buckthorn?
The trials above tested sea buckthorn for up to 12 weeks, and the 2026 constipation trial reported no side effects. It is very sour, so start with a small, well-diluted serving.
Two drug interactions are worth knowing about. Sea buckthorn may slow blood clotting, so taken alongside anticoagulant or antiplatelet medication it can raise the risk of bruising and bleeding. It may also lower blood pressure, which can add to the effect of blood-pressure medication (WebMD drug and supplement monograph). Both are rated moderate interactions, which means check with your doctor or pharmacist rather than avoid it outright.
For the same clotting reason, stop taking concentrated sea buckthorn at least two weeks before planned surgery, and be cautious if you have a bleeding disorder.
If you are pregnant or breastfeeding there is not enough reliable evidence to judge supplement doses, so stick to normal food amounts. If you manage diabetes or any ongoing condition, or take regular medication of any kind, talk to your doctor before adding it daily.
