Barberry Bark Extract

Also known as: Berberis vulgaris, Barberry

Overview

Barberry, scientifically known as *Berberis vulgaris*, is a plant native to Europe, Asia, and Africa. Its bark, roots, and fruits have been traditionally used for medicinal purposes. Barberry contains alkaloids, most notably berberine, which is responsible for many of its pharmacological effects. It is available in various forms, including capsules and extracts. Barberry is primarily recognized for its anti-inflammatory, antioxidant, and antimicrobial properties. Research suggests potential benefits for cardiovascular health, particularly in improving lipid profiles. While studies indicate promising effects, further research is needed to fully understand its comprehensive benefits and mechanisms of action. The quality of available evidence varies, with some high-quality randomized controlled trials and meta-analyses, but more large-scale studies are necessary to confirm these findings.

Benefits

Barberry supplementation has shown significant benefits in improving lipid profiles. A meta-analysis of 5 RCTs involving 339 participants demonstrated that barberry significantly reduced total cholesterol by -23.58 mg/dl, triglycerides by -29.16 mg/dl, and LDL cholesterol by -13.75 mg/dl. These findings suggest potential clinical benefits for cardiovascular health, especially for individuals with dyslipidemia. Additionally, studies suggest anti-inflammatory effects, though specific quantified outcomes are less common. Barberry may also offer benefits for blood glucose control and antioxidant activity, but more research is needed to confirm these effects. The benefits are typically observed within several weeks of consistent supplementation.

How it works

Barberry's mechanism of action primarily involves its key component, berberine, which influences lipid metabolism and inflammation. Berberine may affect cholesterol synthesis or absorption, contributing to improved lipid profiles. It also reduces inflammatory markers such as TNF-α, indicating its anti-inflammatory properties. Berberine interacts with various biological pathways, including AMPK and NF-κB, affecting both the cardiovascular and immune systems. However, berberine's bioavailability is variable, which can influence its overall efficacy. Further research is needed to fully elucidate all mechanisms of action.

Side effects

Barberry is generally considered safe when used appropriately, but it can cause side effects in some individuals. The most common side effects are gastrointestinal disturbances, such as upset stomach or diarrhea. Less common side effects include allergic reactions. Rare side effects are not well-documented. Barberry may interact with blood thinners and diabetes medications, potentially altering their effects. It is contraindicated in pregnancy and breastfeeding due to a lack of safety data. Caution is advised in individuals with diabetes or those taking medications for blood clotting. It is important to consult with a healthcare provider before using barberry, especially if you have pre-existing health conditions or are taking other medications.

Dosage

The minimum effective dose of barberry is not well-established, but typical dosages range from 500 mg to 2 grams per day. The optimal dosage varies based on individual health goals. It is generally recommended to take barberry with meals to minimize gastrointestinal side effects. Capsules or extracts are common forms. While the maximum safe dose is not clearly defined, caution is advised when exceeding 2 grams per day. Bioavailability can be a factor, and certain co-administered compounds may enhance absorption. No specific cofactors are required for barberry to be effective.

Research Sources

  • https://pubmed.ncbi.nlm.nih.gov/30935518/ – This meta-analysis of randomized controlled trials (RCTs) with 339 participants found that barberry supplementation significantly reduced total cholesterol, triglycerides, and LDL cholesterol levels. The study suggests that barberry may have potential benefits for improving lipid profiles and cardiovascular health. However, the authors note that more large-scale studies are needed to confirm these findings.
  • https://pmc.ncbi.nlm.nih.gov/articles/PMC6885761/ – This review article discusses the anti-inflammatory and immunomodulatory effects of barberry. It highlights that barberry exhibits anti-inflammatory properties and can modulate the immune system. While the review provides a comprehensive overview, it lacks specific quantified clinical data, indicating a need for further research to quantify these effects.
  • http://eprints.mui.ac.ir/10099/1/10099.pdf – This study investigates the effects of barberry on metabolic and inflammatory markers in women with polycystic ovary syndrome (PCOS). The results suggest that barberry supplementation may improve insulin sensitivity and reduce inflammation in women with PCOS. The study provides evidence for the potential benefits of barberry in managing metabolic and inflammatory aspects of PCOS.
  • https://examine.com/research-feed/study/w9k6e0/ – This research feed summarizes a study on the effects of barberry on blood glucose control. The study indicates that barberry may have a positive impact on blood glucose levels, suggesting potential benefits for individuals with diabetes or insulin resistance. However, further research is needed to confirm these effects and determine the optimal dosage and duration of supplementation.
  • https://pubmed.ncbi.nlm.nih.gov/33197673/ – This systematic review and meta-analysis, involving 350 participants, examined the effects of barberry on blood pressure. The findings indicated no significant effect on blood pressure. The authors noted heterogeneity among the included studies, suggesting the need for further research to clarify the potential effects of barberry on blood pressure.
