# Dried Sea Buckthorn Berry **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/dried-sea-buckthorn-berry **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-18 **Evidence Score:** 6 / 10 **Category:** Fruit **Also Known As:** Hippophae rhamnoides, Seaberry, Sandthorn, Sallow thorn, Swallow thorn, Tibetan Wonder Berry, Dhar-bu ## Overview Dried sea buckthorn berries contain exceptionally high levels of vitamin C (200-1500mg per 100g) and rare omega-7 fatty acids that support [immune function](/ingredients/condition/immune-support) and [cardiovascular health](/ingredients/condition/heart-health). The bioactive compounds include flavonoids, carotenoids, and palmitoleic acid that reduce [inflammation](/ingredients/condition/inflammation) through multiple cellular pathways. ## Health Benefits - Rich in vitamin C, sea buckthorn berries boost immune health, enhancing the body's ability to fight off infections. This can reduce the duration and severity of colds. - Contains omega fatty acids that support heart health by improving cholesterol levels and reducing inflammation. This lowers the risk of [cardiovascular](/ingredients/condition/heart-health) diseases. - Promotes [skin health](/ingredients/condition/skin-health) by enhancing hydration and elasticity, thanks to its high vitamin E and omega content. This results in a more youthful appearance. - Supports [digestive health](/ingredients/condition/gut-health) by promoting the growth of beneficial gut bacteria, improving digestion and nutrient absorption. - May aid in weight management by boosting [metabolism](/ingredients/condition/weight-management) and reducing fat accumulation, helping to maintain a healthy weight. - Enhances liver health by supporting detoxification processes, aiding in the removal of toxins and improving [liver function](/ingredients/condition/detox). - [Anti-inflammatory](/ingredients/condition/inflammation) properties help reduce inflammation, which can alleviate symptoms of arthritis and other inflammatory conditions. ## Mechanism of Action Sea buckthorn's vitamin C enhances neutrophil function and antibody production while stimulating interferon synthesis for [antiviral](/ingredients/condition/immune-support) activity. The omega-7 fatty acid palmitoleic acid modulates [inflammatory pathway](/ingredients/condition/inflammation)s by reducing NF-κB activation and cytokine production. Flavonoids like quercetin and isorhamnetin provide additional antioxidant effects by scavenging [free radical](/ingredients/condition/antioxidant)s and supporting [endothelial function](/ingredients/condition/heart-health). ## Clinical Summary Small human studies (n=20-80) suggest sea buckthorn supplementation may reduce cold duration by 1-2 days and improve [inflammatory](/ingredients/condition/inflammation) markers. One 12-week trial showed 300mg daily reduced [LDL cholesterol](/ingredients/condition/heart-health) by 15% in hyperlipidemic adults. However, most evidence comes from animal studies and in vitro research. Larger, well-controlled human trials are needed to confirm therapeutic benefits and establish optimal dosing protocols. ## Nutritional Profile - High in vitamin C and vitamin E. - Contains omega-3, -6, -7, and -9 fatty acids. - Provides dietary fiber. ## Dosage & Preparation Consume 5-10 grams daily in teas or as a supplement. Consult a healthcare provider before use. ## Safety & Drug Interactions Sea buckthorn is generally well-tolerated with mild gastrointestinal upset reported in some users. High doses may cause loose stools due to the oil content. The vitamin C content may enhance iron absorption, potentially problematic for individuals with hemochromatosis. Pregnant and breastfeeding women should consult healthcare providers due to limited safety data, though traditional use suggests general safety. ## Scientific Research Research shows that sea buckthorn berries are rich in nutrients that support [skin health](/ingredients/condition/skin-health) and may reduce [inflammation](/ingredients/condition/inflammation). More studies are needed to confirm these benefits. ## Historical & Cultural Context Sea buckthorn berries have been used in traditional Tibetan and Mongolian medicine for centuries, often used to promote skin and [digestive health](/ingredients/condition/gut-health). ## Synergistic Combinations Dried Camu Camu Berry, Dried Elderberry, Dried Aronia Berry ## Frequently Asked Questions ### How much vitamin C is in sea buckthorn berries? Sea buckthorn berries contain 200-1500mg of vitamin C per 100g, making them one of the richest natural sources. This is 15-20 times higher than oranges and exceeds the daily recommended intake in small servings. ### What makes sea buckthorn different from other berries? Sea buckthorn is unique for containing omega-7 fatty acids (palmitoleic acid), which are rare in plant foods. It also provides all four omega fatty acids (3, 6, 7, and 9) plus exceptionally high antioxidant levels from flavonoids and carotenoids. ### Can sea buckthorn help with skin health? The omega-7 fatty acids in sea buckthorn support skin barrier function and may reduce inflammation associated with eczema and dermatitis. Topical and oral use has shown promise in small studies for wound healing and skin hydration. ### What is the recommended dosage for sea buckthorn? Studies typically use 300-1000mg of sea buckthorn extract daily, though no standardized dosage exists. Start with lower amounts due to potential digestive effects and choose products standardized for vitamin C or omega-7 content. ### Does sea buckthorn interact with blood thinning medications? Sea buckthorn may have mild anticoagulant effects due to its omega fatty acid content. Individuals taking warfarin or other blood thinners should consult their physician before use and monitor INR levels if supplementing regularly. ### Is dried sea buckthorn berry safe during pregnancy and breastfeeding? Sea buckthorn is generally considered safe during pregnancy and breastfeeding when consumed in typical food amounts, as it is a whole fruit with a long history of use in traditional medicine. However, pregnant and nursing women should consult with their healthcare provider before taking concentrated supplements, as high doses of certain compounds may affect hormone levels. Most clinical evidence supports moderate consumption, but individual circumstances vary based on overall health and concurrent medications. ### What is the most bioavailable form of sea buckthorn—fresh, dried, oil, or powder? Dried sea buckthorn berry powder and sea buckthorn seed oil tend to have higher bioavailability than whole dried berries because processing breaks down cell walls, making nutrients more accessible for absorption. Sea buckthorn seed oil is particularly rich in omega fatty acids and fat-soluble vitamins, which are better absorbed when consumed with dietary fat. Dried powder offers convenience and stability while retaining most water-soluble vitamins like vitamin C, making it a practical middle ground between fresh berries and concentrated oils. ### Does sea buckthorn berry interact with heart medications or anticoagulants beyond blood thinners? Sea buckthorn contains compounds that may have mild antiplatelet effects, which could potentially interact with blood pressure medications, anticoagulants, and antiplatelet drugs like aspirin or clopidogrel. Individuals taking statins or other cholesterol medications should consult their healthcare provider, as sea buckthorn may have additive effects on lipid profiles. It is important to disclose all supplement use to your doctor, particularly if you are on multiple cardiovascular medications, to avoid unintended interactions or adverse effects. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
