Overview: What is Sea Buckthorn?
Sea buckthorn (Hippophae rhamnoides) is a deciduous shrub native to Europe and Asia, producing vibrant orange berries rich in vitamins, antioxidants, and plant compounds. Its applications span from traditional medicines and foods to modern superfood supplements and skincare.
- Sometimes known as “vitamin tree” or “holy fruit of the Himalayas.”
- Not related to buckthorn (Rhamnus genus); the term “sea” refers to its common coastal habitat.
- All parts are utilized: berries, seeds, leaves, and even bark.
Botanical Profile and History
Sea buckthorn is a hardy, thorny shrub typically found in sandy and rocky soils near rivers, coastlines, or mountains. The history of its use dates back thousands of years, especially in Tibetan, Mongolian, Russian, and Chinese medicine.
- Height: 2–6 meters (6–20 feet)
- Features: silvery-green leaves, dense branches with sharp thorns, clusters of orange-yellow berries
- Resistant to extreme cold, drought, and poor soils—often used for land rehabilitation
- Mentioned in ancient texts as a remedy for skin and digestive ailments
Nutritional Value and Bioactive Compounds
One of sea buckthorn’s biggest draws is its extraordinary nutritional density, reflected in its vitamin, mineral, antioxidative, and fatty acid content. A comparison with common fruits spotlights its status as a natural superfood.
Key Nutritional Highlights:
- Vitamin C: Among the highest of all plant sources (52.86–896 mg/100g), far outpacing oranges, mangoes, bananas, and peaches.
- Vitamins A, E, K, B-group: Present in substantial quantities, supporting vision, skin, nerve function, and immunity.
- Minerals: Contains iron, calcium, magnesium, boron, potassium, phosphorus, and others essential for enzymatic and structural functions.
- Omega Fatty Acids: Uniquely, sea buckthorn oil delivers omegas 3, 6, 9, and the rare omega-7 (palmitoleic acid), important for skin and metabolic health.
- Phytonutrients: Carotenoids (beta-carotene, lutein), flavonoids (quercetin, isorhamnetin, kaempferol), and polyphenols with potent antioxidant properties.
- Protein and Amino Acids: Contains 17 amino acids, including all 7 essentials, supporting tissue repair and metabolic processes.
- Organic Acids: Malic, citric, tartaric, and others contribute to taste and potential metabolic effects.

Frequently Asked Questions (FAQs)
Q: Is sea buckthorn safe for daily use?
A: Sea buckthorn, when consumed as a food or in moderate supplement doses, is considered safe for most people. Topical use is also well-tolerated. Always follow packaging instructions and consult your healthcare provider before high-dose or long-term supplementation, especially if pregnant or on medication.
Q: Does sea buckthorn interact with any medications?
A: Sea buckthorn’s mild blood-thinning effects may interact with anticoagulants (such as warfarin) or antiplatelet drugs. If you are on blood thinners or preparing for surgery, seek medical advice before starting sea buckthorn supplements.
Q: What is the difference between sea buckthorn seed oil and berry oil?
A: Seed oil is extracted from the seeds and is typically higher in omega-3 and omega-6 fatty acids, while berry oil comes from the pulp and contains higher amounts of omega-7 (palmitoleic acid) and carotenoids, making it especially valuable for skin health.
Q: Is it possible to eat sea buckthorn berries raw?
A: Yes, but their intense sourness means most people prefer them cooked, juiced, sweetened, or blended with milder fruits. They are very perishable when raw and rarely found fresh outside their growing regions.
Q: Does heat destroy the nutrients in sea buckthorn?
A: Vitamin C and some antioxidants are sensitive to high temperatures and prolonged storage. To preserve benefits, seek cold-processed juices and minimally heated products, or enjoy fresh/frozen berries.
Q: Are there any proven anti-aging effects of sea buckthorn?
A: Sea buckthorn’s antioxidants (vitamins C and E, carotenoids, polyphenols) help protect skin and body cells from oxidative stress, which is linked to aging. Topical and dietary intake are both popular for maintaining youthful skin, though more large-scale human studies are needed.
Conclusion
Sea buckthorn stands out as a true superfruit, combining exceptional nutritional value, versatile uses, and a potent array of health-promoting compounds.
