- Berberine is a plant compound found in several plants, including barberry, and is commonly sold as a dietary supplement.
-
It has been studied for metabolic health, including blood sugar, cholesterol, and other blood lipids, and weight-related outcomes.
-
Berberine has more than one researched use, but the evidence differs depending on the health outcome and the people being studied.
-
Berberine is an ingredient, not a complete supplement formula, so products can differ in the form, amount, and additional ingredients they contain.
Berberine is a naturally occurring compound found in plants such as barberry and goldenseal. It belongs to a group of plant compounds called alkaloids and has become a popular ingredient in dietary supplements.
Much of the interest around berberine centres on metabolic health. Researchers have studied its potential effects on blood sugar regulation, cholesterol and other blood lipids, body weight, and certain hormone-related metabolic concerns. That doesn't mean every use has the same level of evidence, however. What researchers have found depends on the specific outcome, study population, and formulation being examined.
If you're new to berberine, understanding what it is and why people use it is a good place to start.
Where Does Berberine Come From?
Berberine occurs naturally in several plants, particularly species in the Berberis genus. Barberry (Berberis vulgaris) is one familiar source, while other berberine-containing plants include goldenseal (Hydrastis canadensis) and Oregon grape (Mahonia aquifolium).
The compound is concentrated mainly in the roots, stems, rhizomes, and bark of these plants. Because obtaining useful amounts directly from plant material isn't practical for most people, berberine is extracted and processed for use in dietary supplements.
Today, supplements may contain berberine in different forms, including berberine hydrochloride (berberine HCl), the form used in Bioligent's Berberine+.
What Is Berberine Used For?
Berberine is mainly studied for its potential effects on metabolic health. Human research has examined how it may affect blood sugar, blood lipids, body weight, and related metabolic measures, although the strength of evidence varies by outcome.
Metabolic health and blood sugar
Berberine has been studied for its effects on glucose metabolism, including fasting blood glucose, insulin, and measures of insulin resistance. A 2024 umbrella meta-analysis in Clinical Therapeutics found that berberine supplementation was associated with improvements in several glycemic measures across previous meta-analyses of randomized controlled trials.
In another 2008 clinical trial published in Metabolism, Jun Yin and colleagues studied berberine in 84 adults with type 2 diabetes. After three months, participants taking berberine had reductions in fasting and post-meal blood glucose, HbA1c, fasting insulin, and HOMA-IR, a measure used to assess insulin resistance.
These findings helped build interest in berberine as a compound with effects on several aspects of metabolic health.
Cholesterol and blood lipids
Berberine has also been investigated for its effects on blood lipids, including LDL cholesterol, total cholesterol, and triglycerides. A 2023 systematic review and meta-analysis of 18 randomized controlled trials involving 1,788 adults found reductions in LDL cholesterol, total cholesterol, triglycerides, and apolipoprotein B among participants taking berberine.
This is one reason berberine appears in supplements made for metabolic and cardiovascular health support. However, remember that supplementation should not be treated as a substitute for medical care when someone has high cholesterol or another diagnosed condition.
Weight management
Weight management is another reason berberine has attracted attention, although the human evidence doesn't support treating it as a straightforward weight-loss supplement.
The 2023 umbrella review in PharmaNutrition found a reduction in waist circumference among people taking berberine, but it did not find a statistically significant reduction in body weight or BMI overall.
That makes the research around berberine and body composition particularly interesting: studies have looked at more than the number on the scale, including measures of abdominal size and other metabolic markers.
Hormonal and related metabolic health
Berberine has also been studied in areas where hormonal and metabolic health intersect. Research has examined outcomes such as insulin resistance, blood glucose, blood lipids, and other metabolic markers in people with different metabolic conditions.
A 2021 systematic review and meta-analysis by Ye and colleagues in Frontiers in Pharmacology reviewed randomized clinical trials of berberine used alone across several metabolic disorders. The review found improvements in several measures, including fasting blood glucose, insulin resistance, triglycerides, total cholesterol, and LDL cholesterol.
This broader research is part of why berberine is often discussed in relation to both metabolic and hormone-related health.
What Does Berberine Actually Do in the Body?
Berberine appears to affect several processes involved in glucose and fat metabolism. One of the best-studied pathways is AMP-activated protein kinase (AMPK), an enzyme that helps regulate how cells use and store energy.
When AMPK is activated, cells can increase glucose uptake and adjust how they use energy. Berberine's effects on this pathway may help explain some of the changes seen in studies involving blood sugar and other metabolic markers.
Berberine has also been studied for its effects on insulin signalling and lipid metabolism. These processes are connected to how the body handles glucose and fats, which helps explain why berberine research extends beyond a single metabolic measure.
Is Berberine the Same as a Berberine Supplement?
Berberine refers to the plant compound itself. A berberine supplement is a finished formula that provides berberine in a particular form and amount, sometimes alongside other ingredients.
That means products labelled as berberine supplements don't necessarily contain identical formulas. They can differ in the form of berberine used, the amount provided, and whether other compounds are included.
Bioligent's Berberine+ uses Berberine HCl alongside Chromax® chromium. Berberine HCl is the form of berberine used in the product, while Chromax® is a branded form of chromium picolinate that Bioligent includes for additional metabolic support.
Berberine+ combines these ingredients to support blood sugar balance, metabolism, cravings, weight management, and hormone health. The formula is also made without dairy, gluten, GMOs, synthetic dyes, fillers, PEG, artificial preservatives, or toxic heavy metals, according to Bioligent's product information.
What Should You Know Before Taking Berberine?
Berberine can affect the body in ways that make medication interactions and individual health considerations important. It may also cause digestive side effects, particularly when starting supplementation.
If you take prescription medication or have an existing health condition, talk with your healthcare professional before adding berberine to your routine.
Conclusion
Berberine is a plant compound that has been studied for its potential effects on several areas of metabolic health, including blood sugar, blood lipids, weight-related measures, and hormone-related metabolic health. Its growing use in supplements comes from this broad body of research rather than from a single claimed benefit.
If you're considering berberine, looking at the specific formulation is just as useful as understanding the ingredient itself. Bioligent's Berberine+ combines Berberine HCl with Chromax® chromium for adults interested in metabolic support.
