Sea Buckthorn Seed Oil

Also known as: Sea Buckthorn, Sea Berry, Hippophae rhamnoides L.

Overview

Sea Buckthorn (*Hippophae rhamnoides L.*) is a plant native to Europe and Asia, with its seed oil being a valued dietary supplement. The oil is rich in omega-3, 6, and 9 fatty acids, vitamins, and antioxidants. It is primarily used to support cardiovascular health, skin health, and potentially as an adjunct in managing metabolic syndrome. Research on sea buckthorn seed oil is considered moderate, with several clinical trials exploring its effects. The quality of available evidence varies, including high-quality randomized controlled trials (RCTs) alongside studies with methodological limitations. Sea buckthorn seed oil is generally well-tolerated, making it a popular choice for those seeking natural health support.

Benefits

Sea Buckthorn seed oil has shown potential benefits for cardiovascular and skin health. Studies indicate that it can reduce triglycerides, total cholesterol, and LDL cholesterol while increasing HDL cholesterol in individuals with abnormal lipid metabolism. A meta-analysis of fifteen studies showed these improvements in lipid profiles, although it noted no effect on blood sugar, blood pressure, or BMI in overall subjects. Additionally, sea buckthorn seed oil has been found to normalize blood pressure in hypertensive subjects within 30 days of supplementation. In vitro studies suggest it promotes the proliferation of both normal and dysplastic keratinocytes, potentially aiding in skin regeneration. These benefits are most pronounced in individuals with dyslipidemia or hypertension.

How it works

Sea Buckthorn seed oil primarily modulates lipid metabolism and antioxidant defenses. Its omega fatty acids are believed to interact with lipid metabolism pathways, influencing cholesterol and triglyceride levels. The oil's antioxidant components contribute to reducing oxidative stress, which is beneficial for both cardiovascular and skin health. While the exact molecular targets are not fully elucidated, the observed effects suggest a systemic interaction with cardiovascular and skin systems. The absorption of sea buckthorn seed oil is generally good, although specific bioavailability data remains limited.

Side effects

Sea Buckthorn seed oil is generally considered safe, with few reported side effects. The most common side effect is mild gastrointestinal upset in some individuals. Allergic reactions are rare. Due to its omega-3 content, there is a potential for interaction with anticoagulant medications, so caution is advised for individuals on blood thinners. While there are no well-established contraindications, individuals with bleeding disorders should exercise caution. Pregnant or breastfeeding women should consult with their healthcare providers before using sea buckthorn seed oil. Overall, the safety profile is favorable, but monitoring for adverse effects is always recommended.

Dosage

The minimum effective dose of sea buckthorn seed oil is approximately 0.75 ml per day, as indicated by studies showing normalization of blood pressure in hypertensive subjects. Optimal dosage ranges typically fall between 0.75 to 1.5 ml per day, although this is not definitively established. There are no specific timing recommendations for taking the oil. Seed oil is generally preferred for cardiovascular benefits. No specific cofactors are required for absorption. While a maximum safe dose is not clearly defined, it is advisable to adhere to the recommended dosage ranges to minimize potential side effects.

Research Sources

https://pubmed.ncbi.nlm.nih.gov/36043374/ – This meta-analysis of fifteen studies examined the effects of sea buckthorn on metabolic syndrome factors. The study found that sea buckthorn reduces triglycerides, total cholesterol, LDL cholesterol, and increases HDL cholesterol. However, it had no significant effect on blood sugar, blood pressure, or BMI, and the study noted high heterogeneity among the included studies.
https://pubmed.ncbi.nlm.nih.gov/27522605/ – This randomized controlled trial involving 106 subjects (32 normal, 74 hypertensive/hypercholesterolemic) investigated the impact of sea buckthorn seed oil on cardiovascular risk factors. The study showed that sea buckthorn seed oil normalized blood pressure in hypertensive subjects and reduced cholesterol and triglycerides. The study was limited by a small sample size for some subgroups.
https://www.mdpi.com/2075-4426/11/4/278 – This in vitro study examined the effects of sea buckthorn seed oil on skin cell proliferation using normal and dysplastic keratinocytes. The study found that sea buckthorn seed oil promotes the proliferation of both normal and dysplastic keratinocytes. The in vitro design limits the direct clinical applicability of these findings.
https://onlinelibrary.wiley.com/doi/abs/10.1002/ptr.7596 – This abstract examines the effects of sea buckthorn on various health outcomes. Further details would be needed to provide a more comprehensive summary, but it suggests potential benefits that warrant further investigation.
