What is Berberine?
Berberine is a compound found in several different plants, including Barberry (Berberis vulgaris), Oregon Grape (Mahonia aquifolium), Goldenseal (Hydrastis canadensis), and Chinese goldthread (Coptis chinensis) Berberine has a 3000-year history of use in traditional Chinese and Indian medicine [R, R].
It has many beneficial and potentially beneficial effects on health, especially for people with diabetes or cholesterol issues.
Health Benefits of Berberine
1) Berberine Helps Fight Diabetes
A meta-analysis determined that berberine is an effective treatment for type 2 diabetes [R].
In one study, berberine (0.5 g, 3x/day for 3 months) performed similarly to metformin (a diabetes medication). It reduced hemoglobin A1c (HbA1c) levels, fasting blood glucose, blood glucose following a meal, and triglycerides levels in 36 patients with type 2 diabetes. In the other half of the study, 48 patients with type 2 diabetes treated with berberine had similar results and also reduced plasma insulin. Total cholesterol and LDL decreased as well [R].
In another study, 1 g/day berberine reduced fasting and post-meal blood glucose and HbA1c, triglyceride, total cholesterol, and LDL levels (RCT of 116 patients with type 2 diabetes) [R].
Berberine can potentially help with diabetes in a number of different ways:
- Directly increasing AMPK, which stimulates glucose uptake in muscle cells and helps balance high blood sugar (rat and cell studies) [R, R, R]
- Delay the breakdown of carbohydrates into simple sugars (rat study) [R]
- Enhancing glucagon secretion (rat study) [R]
- Mimics insulin action by increasing the ability of the body to take up glucose (cell study) [R]
- Decreasing glucose transport through the intestinal lining (cell study) [R]
- Increasing adiponectin, a protein which helps regulate blood sugar levels (through AMPK) (cell study) [R]
- Activating the blood sugar transport activity of glucose transporter 1 (GLUT1) (cell study) [R]
- Activating the fatty acid receptor GPR40 (cell study) [R]
- Protecting the beta-cells of the pancreas against cell death (cell study) [R]
- Inhibiting production of glucose in the liver (rat study) [R]
- Improving the gut microbiota (rat study) [R]
- Inhibiting NF-kappaB (NF-kB) (cell study) [R]
- Increasing insulin receptor expression (cell study) [R]
2) Berberine Improves Cholesterol Levels
Both berberine and a berberine supplement (berberine, policosanol, red yeast extract, folic acid, and astaxanthin) given daily for 4 weeks significantly reduced total cholesterol, LDL, and triglycerides and increased HDL (SB-RCT with 40 subjects with moderate cholesterol issues). Another study with 32 patients with high cholesterol, demonstrated that berberine supplementation for 3 months greatly reduced cholesterol, triglycerides, and LDL-cholesterol [R, R].
A supplement containing berberine (500 mg berberine, 10 mg policosanol, 200 mg red yeast rice, 0.2 mg folic acid, 2.0 mg coenzyme Q10, and 0.5 mg astaxanthin) lowered total cholesterol, LDL, and insulin resistance but didn’t affect HDL levels (SB-RCT with 80 patients with cholesterol issues) [R, R, R].
This cholesterol-lowering effect was also seen in mice [R].
The ability of Berberine to lower LDL is via:
- Increasing activity at the LDL receptor in the liver [R].
- Reducing hepatocyte nuclear factor 1alpha [R].
- Inhibiting lipid synthesis through activation of AMPK [R].
3) Berberine Can Aid Weight Loss
Berberine (500 mg, 3/day for 12 weeks) resulted in an average weight loss of 5 lbs, as well as an improvement of triglyceride and cholesterol stats in obese patients [R].
Berberine inhibited the production of body fat cells through up-regulation of C/EBP inhibitors, CHOP and DEC2 (cell study) [R].
4) Berberine May Benefit Heart Disease
Berberine (1.2-2.0 g/day) combined with several conventional therapies increased the quality of life (exercise capacity and reduced fatigue) and decreased death rates (RCT of 156 patients with chronic congestive heart failure) [R].
5) Berberine Has Anti-Parasitic Effects
Berberine combined with malaria medication (pyrimethamine) was more effective against getting rid of the infection than other combinations of drugs (pyrimethamine and tetracycline or pyrimethamine and cotrimoxazole) (RCT of 215 patients) [R].
6) Berberine Heals Canker Sores
A topical application of Berberine gelatin (5 mg/g) may be an effective treatment for canker sores (DB-RCT with 84 participants) [R].
The following effects were seen in animal studies.
7) Berberine May Help With Gut Issues
Berberine was able to inhibit secretions of toxins produced by intestinal bacteria (E. coli and Vibrio cholerae) in animal models, which might explain its use as an anti-diarrhea agent in Chinese and Indian medicine [R].
It also preferentially increased short-chain fatty acid(SCFA) producing bacteria in rat guts. Its normalizing effect on gut bacteria was able to improve symptoms of fatty liver disease in mice, in another study [R, R].
It also inhibits particular human intestinal bacteria (cell study) [R].
8) Berberine May Reduce Inflammation
Inflammation of the blood vessels was improved by berberine (rat study) [R].
9) Berberine May Help With Arthritis
10) Berberine May Help Improve Learning & Memory
Berberine was thought to improve memory by:
- stimulating cholinergic enzyme activity and reducing inflammation (rat study) [R].
- preventing the cell death of neurons with reduced blood flow (low oxygen) to the brain (rat study) [R].
11) Berberine May Protect the Liver
Berberine protected against toxin-induced liver damage in rats via antioxidant effects [R].
It also protected against infection-related liver damage in mice [R].
12) Berberine May Help With Colitis
In rats with ulcerative colitis, berberine reduced inflammation but also killed the commensal (good) bacteria in the gut. In another study, berberine reduced inflammation in the gut of mice with colitis and intestinal damage [R, R].
13) Berberine May Help With Diabetic Complications
14) Berberine May Help Lower Blood Pressure
15) Berberine May Reduce Depression
16) Berberine May Protect Brain Cells
Berberine reduced brain cell death in rats that were given strokes via reduced blood flow to the brain [R].
In a cell study, berberine increased levels of enzymes associated with regulation of inflammation of brain cells [R].
17) Berberine May Improve Mitochondrial Function
The following effects were seen in cell studies.
18) Berberine Is a Potential Anti-Cancer Agent
- Brain Cancer: Berberine induces cell death in human brain cancer (glioblastoma) cells. It had a potent anti-tumor effect on glioblastoma multiforme (GBM), which is the most common type of malignant brain cancer and known to be a grim diagnosis [R, R].
- Breast Cancer: Coptis extracts (which contain berberine) enhance the anticancer effect of estrogen receptor antagonists on human breast cancer cells. The effect of Berberine on the growth of anoikis-resistant breast cancer cells was greater than treatment with doxorubicin, a drug commonly used to treat breast cancer [R, R].
- Cervical Cancer: Berberine-induced cell death in human cervical cancer cells [R, R].
- Colon Cancer: Berberine-induced cell death in colon tumor cells (through activation of an apoptosis-inducing factor). Derivatives of berberine are even stronger against colon cancer than the original compound [R, R].
- Liver Cancer: Berberine-induced cell death in liver cancer cells. Berberine also inhibited Aspergillus flavus, a common fungal infection that produces cancer-causing compounds in the liver [R, R].
- Lymphoma: Berberine is a potential anti-tumor agent for primary effusion lymphoma (PEL), which is a type of cancer associated with AIDS [R].
- Oral Cancer: Berberine-induced cell death in human oral cancer cells [R, R].
- Thyroid Cancer: Berberine reduced thyroid cancer cell growth [R, R].
19) Berberine is Antibacterial and Antifungal
Berberine shows effectiveness against a variety of microbes in a cell study [R]:
- S. aureus
- P. aeruginosa
- E. coli
- Candida albicans
Berberine had antiviral activity against herpes simplex virus (cell study) [R].
21) Berberine May Potentially Benefit Alzheimer’s Disease
Repeated doses of berberine inhibit cytochromes P450 in humans, altering the normal breakdown of drugs [R].
Side Effects of Berberine
Mild adverse digestive effects were observed among a few subjects in studies, such as abdominal discomfort (nausea, distension, diarrhea). Constipation was ameliorated by reducing the dose of berberine [R].
Several people commented that berberine supplementation helped them with their blood sugar levels.
A few people commented that berberine is great.
One person lost a significant amount of weight from taking it but another user said there was no change in their weight.
One user said they didn’t see any changes in their health.
