Wild Crafted Buckthorn
Also known as: Sea buckthorn, Wild crafted buckthorn, Hippophae rhamnoides
Overview
Hippophae rhamnoides, commonly known as sea buckthorn or wild crafted buckthorn, is a deciduous shrub native to Europe and Asia. Its orange berries are a rich source of various bioactive compounds, including flavonoids, vitamins (C and E), carotenoids, fatty acids, and polysaccharides. Wild crafted buckthorn specifically refers to naturally harvested varieties of this plant, distinguishing it from cultivated forms and from *Rhamnus* species, which are used as laxatives. Traditionally, it has been utilized for both nutritional and medicinal purposes, particularly for supporting cardiovascular health and managing components of metabolic syndrome. Research indicates its potential in improving lipid profiles and providing antioxidant support, with a moderate to advanced level of scientific inquiry, including multiple randomized controlled trials and meta-analyses.
Benefits
Sea buckthorn primarily offers significant benefits in improving lipid profiles, particularly in individuals with abnormal lipid metabolism or metabolic syndrome. Meta-analyses of randomized controlled trials have shown statistically significant reductions in triglycerides (SMD -0.722), total cholesterol (SMD -0.345), and LDL cholesterol (SMD -0.396), alongside an increase in HDL cholesterol (SMD +0.370). These effects are considered clinically relevant for cardiovascular risk reduction. While it does not significantly impact blood glucose, blood pressure, or BMI in general populations, its rich content of bioactive compounds suggests antioxidant and anti-inflammatory properties that may contribute to overall metabolic health. The benefits are most pronounced in individuals with dyslipidemia, with limited evidence for healthy individuals. Improvements are typically observed within weeks to a few months of consistent use.
How it works
Sea buckthorn exerts its effects primarily through the modulation of lipid metabolism, driven by its rich composition of antioxidant flavonoids and fatty acids. It also possesses anti-inflammatory properties, potentially by downregulating pro-inflammatory cytokines. The polysaccharides present in sea buckthorn may contribute to immune modulation and gut health. Its bioactive compounds interact with various molecular targets involved in lipid metabolism pathways, oxidative stress markers, and inflammatory mediators. The absorption and bioavailability of these compounds, such as flavonoids and carotenoids, can vary, with formulation and extraction methods influencing their efficacy within the body.
Side effects
Sea buckthorn is generally well-tolerated, with clinical trials reporting no serious adverse events. The most commonly reported side effect is mild gastrointestinal discomfort, which occurs rarely. There are no well-documented drug interactions, but caution is advised when combining sea buckthorn with lipid-lowering medications or anticoagulant drugs due to the potential for additive effects. No specific contraindications have been established. However, due to a lack of sufficient data, caution is recommended during pregnancy and lactation. Research in special populations, such as the elderly or individuals with chronic diseases, is limited, and further studies are needed to fully assess its safety in these groups.
Dosage
The effective dosage of sea buckthorn varies across studies, with typical daily doses ranging from 250 mg to 1,000 mg of sea buckthorn extract or its equivalent. An optimal dosage has not been firmly established due to the heterogeneity in dosing regimens across meta-analyses. There is no clearly defined maximum safe dose, as clinical trials have not reported dose-limiting toxicity. Sea buckthorn is usually administered daily, and the timing relative to meals is not standardized. For consistency and efficacy, extracts standardized for their flavonoid or polysaccharide content are often preferred. Formulations rich in fatty acids may enhance the bioavailability of its active compounds. No specific cofactors are required for its efficacy.
FAQs
Is wild crafted buckthorn the same as sea buckthorn?
Yes, 'wild crafted buckthorn' typically refers to naturally harvested *Hippophae rhamnoides*, which is the scientific name for sea buckthorn. It is distinct from *Rhamnus* species, which are used as laxatives.
Is it safe for long-term use?
Current evidence supports the safety of sea buckthorn for short- to medium-term use. However, comprehensive data on its long-term safety are still limited, and further research is needed.
How soon do benefits appear?
Improvements in lipid profiles, such as reductions in cholesterol and triglycerides, have been observed within a few weeks to several months of consistent sea buckthorn supplementation.
Does it help with weight loss?
No significant evidence from clinical trials supports that sea buckthorn has a direct effect on BMI or promotes weight reduction.

- https://pubmed.ncbi.nlm.nih.gov/36043374/ – This meta-analysis of 15 randomized controlled trials (RCTs) investigated the effects of sea buckthorn on metabolic syndrome components. It found that sea buckthorn significantly improved lipid profiles (triglycerides, total cholesterol, LDL, HDL) but had no significant effect on blood glucose, blood pressure, or BMI. The study noted high heterogeneity among trials and highlighted that effects were primarily observed in subjects with dyslipidemia.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10217465/ – This narrative review provides a detailed overview of the bioactive compounds found in sea buckthorn and their proposed mechanisms of action. It supports the role of sea buckthorn in modulating lipid metabolism and its antioxidant effects, offering a comprehensive understanding of its potential health benefits beyond primary clinical trial data.
- https://ouci.dntb.gov.ua/en/works/lDgD5Qd4/ – This systematic review and meta-analysis of 11 RCTs specifically focused on the lipid-lowering effects of sea buckthorn in adults with lipid abnormalities. The findings were consistent with other meta-analyses, confirming significant improvements in lipid parameters. The study was noted for its high quality and adequate sample sizes, despite some moderate heterogeneity among the included studies.
