Sea buckthorn juice powder

Also known as: Sea buckthorn, seaberry, Sea buckthorn juice powder, Hippophae rhamnoides L.

Overview

Sea buckthorn juice powder is derived from the dehydrated berries of the Hippophae rhamnoides L. plant, a deciduous shrub native to Europe and Asia. This plant-based dietary supplement is rich in bioactive compounds such as flavonoids, vitamins (especially C and E), carotenoids, and essential fatty acids. It is primarily utilized for its potential benefits in cardiovascular health, particularly in managing lipid profiles, and is also explored for its anti-inflammatory and skin health properties. While research is ongoing, current evidence suggests promising effects on lipid metabolism, though its impact on blood glucose and blood pressure is less consistent. The powder form offers a convenient way to incorporate the nutritional benefits of sea buckthorn berries into the diet.

Benefits

Sea buckthorn juice powder offers several evidence-based benefits, primarily in cardiovascular health. A significant benefit is the improvement of lipid profiles, particularly in individuals with dyslipidemia or metabolic syndrome. A 2022 meta-analysis of 15 randomized controlled trials (RCTs) demonstrated that sea buckthorn supplementation significantly reduced triglycerides, total cholesterol, and LDL cholesterol, while increasing HDL cholesterol. These effects are considered moderate but clinically relevant. Additionally, a small double-blind RCT indicated that sea buckthorn berry oil can reduce ADP-induced platelet aggregation, suggesting potential anti-thrombotic effects. Some clinical trials also suggest benefits for skin health and wound healing, though this evidence is less robust and requires further confirmation. Effects on blood sugar, blood pressure, and BMI have been inconsistent or not significant in meta-analyses, with only small, preliminary studies suggesting modest improvements in insulin response in prediabetic individuals. The benefits on lipid metabolism appear most pronounced in populations with existing lipid abnormalities.

How it works

Sea buckthorn's beneficial effects are primarily attributed to its rich composition of antioxidant flavonoids, vitamins, and essential fatty acids. These compounds modulate lipid metabolism by influencing enzymes involved in cholesterol and triglyceride synthesis and breakdown, leading to improved lipid profiles. Its anti-platelet aggregation effects are likely due to specific compounds that interfere with platelet activation pathways, thereby reducing the risk of clot formation. The plant's antioxidants also combat oxidative stress, which is a key contributor to cardiovascular disease and various inflammatory conditions. While the exact molecular targets are still under investigation, the overall mechanism involves a synergistic action of its diverse bioactive components on cellular and systemic processes.

Side effects

Sea buckthorn juice powder is generally considered safe, with a low incidence of adverse effects reported in clinical trials. Meta-analyses and randomized controlled trials have not reported significant common side effects. However, due to its potential anti-platelet effects, caution is advised when used concurrently with anticoagulants or antiplatelet drugs (e.g., warfarin, aspirin, clopidogrel), as this combination could theoretically increase the risk of bleeding. Individuals with known bleeding disorders should also exercise caution. There are no well-established contraindications, but data on its safety in special populations, such as pregnant or lactating women, are limited, and its use in these groups is not well-studied. No major safety concerns or rare side effects have been well-documented, but as with any supplement, individual sensitivities can occur.

Dosage

The optimal dosage for sea buckthorn juice powder varies depending on the concentration of the extract and the desired effect, as well as individual factors. In clinical trials, doses equivalent to 300 ml of juice or 5 grams of berry oil daily have been used. Generally, dosages range from 300 mg to several grams per day. For lipid profile improvement, studies typically involve daily supplementation for 4 to 12 weeks, with benefits often observed within this timeframe. The maximum safe dose has not been clearly established, but clinical trials have not reported toxicity at the studied dosages. Sea buckthorn is available in various forms, including juice powder, berry oil, and whole berry extracts, and their bioavailability may differ. Co-ingestion with dietary fats may enhance the absorption of its fat-soluble components. There are no specific cofactors identified as necessary for its efficacy.

FAQs

Is sea buckthorn juice powder safe?

Yes, it is generally considered safe with minimal reported side effects in clinical trials. However, caution is advised if you are on blood-thinning medications.

Does it help with cholesterol?

Yes, especially in individuals with abnormal lipid profiles, it can significantly improve lipid markers by lowering triglycerides, total cholesterol, and LDL, while increasing HDL.

Will it lower blood sugar?

Evidence for blood sugar lowering is limited and inconsistent. It is not recommended as a primary agent for glucose control.

How long before benefits appear?

Benefits on lipid profiles typically become apparent within 4 to 12 weeks of consistent daily supplementation.

Can it be used with blood thinners?

Caution is advised due to its potential anti-platelet effects, which could theoretically increase the risk of bleeding when combined with blood-thinning medications.

https://pubmed.ncbi.nlm.nih.gov/36043374/ – This 2022 meta-analysis of 15 RCTs investigated the effects of sea buckthorn on lipid profiles, blood glucose, blood pressure, and BMI. It found significant reductions in triglycerides, total cholesterol, and LDL, and an increase in HDL in subjects with abnormal lipid metabolism, but no significant effects on blood glucose, blood pressure, or BMI. The study highlights the potential of sea buckthorn for dyslipidemia management.
https://www.frontiersin.org/journals/cardiovascular-medicine/articles/10.3389/fcvm.2024.1477636/full – This 2024 double-blind RCT, although small, explored the effects of sea buckthorn berry oil on platelet aggregation and lipid profiles in healthy males. It reported decreased ADP-induced platelet aggregation and some mixed effects on lipids (increased HDL, increased TG, no change in LDL or TC). The study suggests potential cardiovascular protective effects through anti-platelet activity.
