Sea Buckthorn Juice; Powder
Also known as: sea buckthorn berry, sea buckthorn juice, sea buckthorn oil, sea buckthorn powder, sandthorn, sallowthorn, Hippophae rhamnoides
Overview
Sea buckthorn (Hippophae rhamnoides) is a deciduous shrub native to parts of Europe and Asia, recognized for its bright orange berries that are rich in vitamins, minerals, and antioxidants. This herbal supplement is prized for its high content of polyunsaturated fatty acids, especially omega-7, and vitamin C, making it beneficial for various aspects of health. Traditionally, sea buckthorn has been utilized for its purported ability to support cardiovascular health, lipid metabolism, and boost antioxidant defenses. The current body of research includes several randomized controlled trials and meta-analyses that confirm its potential health benefits, particularly in the management of dyslipidemia. While the research is not exhaustive, the evidence suggests that sea buckthorn supplementation can significantly enhance lipid profiles and offers substantial anti-inflammatory effects.
Benefits
Sea buckthorn has been associated with multiple health benefits, especially concerning lipid metabolism. A meta-analysis of 15 randomized controlled trials revealed significant decreases in triglycerides (p < .001), total cholesterol (p = .021), and low-density lipoprotein (LDL) cholesterol (p = .031), alongside an increase in high-density lipoprotein (HDL) cholesterol (p = .021). These effects are particularly pronounced in individuals exhibiting abnormal lipid profiles or those with metabolic syndrome. Additionally, sea buckthorn exhibits anti-inflammatory properties, reducing cytokine production and oxidative stress markers. Significant clinical improvements in lipid profiles are commonly observed after 8-12 weeks of supplementation, highlighting its therapeutic potential.
How it works
The health benefits of sea buckthorn are attributed to its bioactive compounds, which influence lipid metabolism through various biological pathways. Key mechanisms include modulation of PPARγ, PPARα, and ABCA1 gene expressions, pivotal in cholesterol and fatty acid metabolism. Activation of the AMPK/SIRT1 pathway augments insulin sensitivity, further supporting lipid regulation. Flavonoids in sea buckthorn also inhibit inflammatory signaling pathways such as TLR4/IL-6/STAT3 and MAPK, thereby reducing inflammation and offering relief from atherosclerotic symptoms, promoting cardiovascular health.
Side effects
Sea buckthorn is generally recognized as safe; however, some users (over 5%) may report mild gastrointestinal discomfort, including diarrhea or abdominal pain. There are no significant reports of rare or severe adverse effects associated with its consumption. Drug interactions are not well-documented; still, individuals on anticoagulant therapies should proceed with caution due to the potential for enhanced antiplatelet activity. While specific contraindications are sparse, those with allergies to any sea buckthorn components are advised to avoid the supplement. Pregnant or breastfeeding women are encouraged to consult healthcare professionals prior to use, given the limited safety research in these populations. Overall, while substantial side effects are uncommon, a consideration of personal health factors is recommended when taking this supplement.
Dosage
Recommended dosages for sea buckthorn can vary based on the formulation and intended health outcomes. Clinical studies support effective dosages between 500 mg to 2 grams per day for lipid-lowering benefits, with many experts suggesting a range of 1-3 grams per day for optimal results depending on the specific form (juice, powder, or oil). While there is no established upper limit for safe consumption, doses exceeding 3 grams daily have not been extensively studied. To enhance absorption, especially of oil and powdered forms, it is advisable to take supplements with meals, particularly alongside fatty foods that can aid in the uptake of lipid-soluble nutrients.
