Buckthorn Bark Extract

Also known as: Hippophae rhamnoides, sea buckthorn extract, sea buckthorn oil, sea buckthorn berries, sea buckthorn leaves, sea buckthorn bark, Sea buckthorn

Overview

Sea buckthorn (*Hippophae rhamnoides L.*) is a deciduous shrub found in Europe and Asia, renowned for its nutrient-rich berries, leaves, and bark. This plant contains various bioactive compounds, including polyphenols, flavonoids, carotenoids, and essential fatty acids, contributing to numerous health benefits. Traditionally used in herbal medicine, sea buckthorn is particularly recognized for its antioxidant and anti-inflammatory properties. Recent research highlights its potential to support cardiovascular health, enhance lipid profiles, assist with metabolic syndrome management, and provide benefits for female reproductive health. While evidence supporting these claims ranges from moderate to strong, further studies are needed to clarify its effectiveness across different health conditions. Sea buckthorn is available in multiple forms, such as oils, capsules, and extracts derived from its berries, leaves, and bark.

Benefits

Sea buckthorn has been linked to multiple health benefits, particularly in lipid metabolism. A meta-analysis of 15 randomized controlled trials showed significant reductions in triglycerides and total cholesterol levels, with concurrent increases in high-density lipoprotein (HDL) cholesterol. Its antioxidant properties reduce oxidative stress markers and improve antioxidant enzyme activity, making it beneficial for individuals with dyslipidemia. Emerging evidence also points to its cardiovascular protective effects and benefits for female reproductive health. Nonetheless, the need for more expansive clinical trials remains to ensure robust evidence for these benefits and their applicability to varying populations.

How it works

The health benefits of sea buckthorn primarily stem from its abundant polyphenolic compounds, particularly isorhamnetin and quercetin. These compounds act as potent antioxidants, neutralizing reactive oxygen species (ROS) and enhancing the body's antioxidant defenses. Additionally, sea buckthorn exhibits anti-inflammatory effects by modulating inflammatory cytokines, reducing overall inflammation. It also impacts lipid metabolism, decreasing levels of detrimental lipids while promoting beneficial lipids, thereby supporting heart health.

Side effects

Sea buckthorn is generally regarded as well tolerated, with adverse effects being infrequent and typically mild. Common side effects, which may occur in more than 5% of users, include gastrointestinal discomfort. Severe reactions are less common, reported at rates lower than 5%. Caution is advised for those on statins or lipid-lowering medications due to potential interactions. Allergic reactions could arise, particularly in individuals with known sensitivities. Pregnant and breastfeeding women should consult with healthcare providers due to limited safety data regarding long-term use in these populations. Overall, sea buckthorn is considered safe for most people when consumed appropriately.

Dosage

Recommended dosage for sea buckthorn varies based on desired health outcomes, typically ranging from 500 mg to 3 grams per day for lipid metabolism enhancement, with many users opting for 1 to 3 grams daily. While there are no firmly established maximum safe dosages, caution is advised for dosages exceeding 3 grams due to a lack of safety data. Taking sea buckthorn supplements with meals is recommended to improve absorption, and active compound concentration may vary between products derived from berries, leaves, or bark.
