Today, with the backing of modern science, berberine is gaining attention for its potential health benefits, ranging from improving metabolic functions to fighting inflammation.
Berberine is classified as an alkaloid, a type of compound that plants produce, which often has potent effects on human physiology. It’s found in the roots, rhizomes, stems, and bark of plants such as goldenseal, Oregon grape, barberry, and tree turmeric.
The bright yellow color of berberine not only makes it visually distinctive but also indicates its presence in certain plants, traditionally used to dye wool, leather, and wood.
How does berberine work?
Berberine has been tested in hundreds of various analyses. It was presented to have powerful effects on many biological systems.
After ingesting berberine, it gets carried in by the body and transported into the bloodstream. Then, it travels into the body’s cells. It binds to several different “molecular targets” inside the cells and changes their function, similar to how pharmaceutical drugs work.
Without getting into much detail, as the biological mechanisms are complicated and diverse – one of the primary actions of berberine is to activate an enzyme inside cells called AMPK (AMP-activated protein kinase).
This enzyme, sometimes referred to as a “metabolic master switch, ” is found in the cells of various organs, including the brain, heart, muscle, kidney, and liver.
It also plays a significant role in controlling metabolism. Berberine also affects multiple other molecules inside cells and may influence which genes turn on or off.

Berberine causes a notable reduction in blood sugar levels
Type 2 diabetes is a severe disease that has become extremely common in recent decades, generating millions of deaths yearly.
Represented by raised blood sugar (glucose) levels, either induced by insulin resistance or deficiency of insulin. Over time, elevated blood sugar levels can hurt the body’s organs and tissues, leading to various health problems and a shortened lifespan.
Many studies show that berberine can remarkably reduce blood sugar levels in individuals with type 2 diabetes. Its effectiveness is similar to the prevalent diabetes drug metformin (Glucophage) and seems to work via multiple different mechanisms:
- Augments glycolysis, enabling the body to break down sugars inside cells
- Increases the figure of beneficial bacteria in the gut
- Lessens sugar production in the liver
- Lowers insulin resistance, driving the blood sugar decreasing hormone insulin more effective
- Slows the disintegration of carbohydrates in the gut
In one study of 116 diabetic patients, a gram of berberine a day reduced fasting blood sugar by 20%, from 7.0 to 5.6 mmol/L (126 to 101 mg/dL), indicating a shift from from diabetic to normal levels. It also lowered hemoglobin A1c by 12% (a marker for long-term blood sugar levels) and improved blood lipids like cholesterol and triglycerides.
A collective review of 14 studies reveals that berberine is as productive as oral diabetes drugs, including glipizide, metformin, and rosiglitazone. It fares very well with lifestyle modifications and has additive effects when dispensed with other blood sugar-lowering drugs.
Per online discussions, you often see people with sky-high blood sugars standardizing them just by taking this supplement.
Berberine may help you drop the pounds
Berberine may also be useful as a weight loss supplement. So far, two studies have examined its effects on body weight [2].
In a 12-week study on obese individuals, 500 mg taken three times per day caused an average of around 5 pounds of weight loss. The participating individuals also lost 3.6% of their body fat.
Another impressive study conducted was on 37 men and women with metabolic syndrome. This study lasted three months, and the participants took 300 mg daily.
The participants only dropped their body mass index (BMI) levels from 31.5 to 27.4 or from obese to overweight. They also lost belly fat and improved various health markers.
The researchers consider that the improved function of fat-regulating hormones like adiponectin, insulin, and leptin causes weight loss.
Berberine also seems to deter the growth of fat cells at the molecular level. Although, more analysis is needed on the weight loss effects of berberine.
Lowers cholesterol and may scale down the risk of heart disease
Heart disease is presently the world’s most typical cause of untimely death. Several factors that can be gauged in the blood are associated with an increased risk of heart disease. It turns out that berberine has been shown to improve a lot of these aspects.
According to an analysis of 11 studies, it can:
- Reduced overall cholesterol by 0.61 mmol/L (24 mg/dL).
- Lower LDL (low-density lipoprotein or “bad fat”) by 0.65 mmol/L (25 mg/dL).
- Lessened blood triglycerides by 0.50 mmol/L (44 mg/dL).
- Higher HDL (high-density lipoprotein or “good cholesterol”) by 0.05 mmol/L (2 mg/dL).
It has also been documented to lower apolipoprotein B by 13-15%, a critical risk factor. Per some studies, berberine works by inhibiting an enzyme called PCSK9, leading to more LDL being removed from the bloodstream.
It is also good to note that diabetes, obesity, and high blood sugar levels are primary heart disease risk factors, all of which appear to improve with taking berberine.
What is the danger of taking berberine?
When considering berberine as a supplement, knowing its benefits is as important as knowing its potential side effects and risks [3].
Berberine is generally well-tolerated, but like any active compound, it can cause side effects, especially when taken in high doses or without proper guidance.
Here are some common side effects associated with berberine:
- Some people might experience gastrointestinal symptoms such as diarrhea, constipation, and abdominal pain. These are typically mild and often decrease with continued use.
- Berberine can lower blood glucose levels, which is beneficial for many, but it poses a risk of hypoglycemia, particularly in people with diabetes or those taking other blood sugar-lowering medications.
- High doses of berberine have been linked to changes in liver function. Monitoring liver enzymes is advisable, especially if you are taking berberine long-term.
Berberine and its effect on blood sugar levels
Raised blood sugar levels indicate conditions like diabetes and prediabetes due to reduced insulin production or decreased sensitivity to insulin.
Although it’s standard for your blood sugar levels to fluctuate throughout the day, prolonged high blood sugar levels can cause diverse health problems, including organ damage.
A decent amount of animal research implies berberine may help lower blood sugar levels through various pathways, including the following:
- Augmenting glycolysis, or the breakdown of glucose
- Controlling metabolism
- Delaying carbohydrate absorption from the gut
- Improving insulin sensitivity
- Lowering glucose production in the liver
- Raising nitric oxide (NO) production, which helps widen arteries
- Stimulating insulin production
Several studies on individuals with type 2 diabetes show that consuming 600–2,700 mg of berberine may diminish fasting and long-term blood sugar levels by up to 20% and 12%, subsequently, specifically when taken alongside blood sugar medication.
Similarly, research suggests berberine may aid in supporting the blood-sugar-lowering effects of other diabetes medications when taken with them.
Accordingly, berberine seems to be a promising blood-sugar-lowering treatment. This may be particularly helpful to those who cannot take diabetes medications because of heart, kidney, or liver disease.

Insufficient evidence to rate berberine’s effectiveness
Here are several conditions which berberine may have been used for but does not carry enough evidence of efficacy:
| Burns | Early research suggests that using an ointment containing beta-sitosterol and berberine can medicate second-degree burns as adequately as conventional treatment with silver sulfadiazine. |
| Congestive heart failure (CHF) | Early research implies that berberine can reduce some symptoms and lessen the death rate in some individuals with congestive heart failure. |
| Diarrhea | Some early research tells us that berberine sulfate can decrease diarrhea in people with certain bacterial infections. In addition, berberine hydrochloride seems to hasten recovery time for people with diarrhea when added to some standard treatments [4]. Although, berberine does not seem to enhance the effects of tetracycline in treating diarrhea related to cholera infection. |
| Glaucoma | Early research says that using eye drops containing berberine and tetrahydrozoline for three days does not lessen eye pressure in individuals with glaucoma better than eye drops containing tetrahydrozoline alone. |
| Hepatitis | Early research says that taking berberine daily for two months lowers triglycerides, blood sugar, and markers of liver damage in individuals with diabetes and hepatitis B or C. |
| Injuries caused by radiation | Some early research reports that taking berberine during radiation therapy can reduce the occurrence and severity of some damages provoked by radiation in patients receiving treatment for cancer. |
| Liver disease | Early research says that taking berberine for 12 weeks lowers fat in the blood and markers of liver damage in individuals suffering from liver disease and diabetes. |
| Sparse blood platelet counts (thrombocytopenia) | Blood platelets are essential for the process of blood clotting. According to early research, taking berberine for 15 days – either by itself or along with prednisolone, can raise the count of blood platelets in individuals with low blood platelet counts. |
| Menopausal symptoms | Early research mentions that taking berberine and soy isoflavones can lessen menopausal indications. |
| Metabolic syndrome | Taking an aggregate product (Armolipid Plus) with berberine, red yeast rice, and policosanol might improve blood flow and blood pressure in individuals suffering from metabolic syndrome. |
| Obesity | Early research maintains that taking berberine for 12 weeks can lower weight in obese people by around five pounds. |
| Osteoporosis | Early research suggests that taking berberine with vitamin D3, vitamin K, and a chemical found in hops for 14 weeks can lower bone loss in postmenopausal women with osteoporosis. |
| Ovary disorder also known as polycystic ovary syndrome (PCOS) | Early research adds that berberine can lower cholesterol, blood sugar, triglycerides, testosterone, and waist-to-hip ratio in women with PCOS. |
| Stomach ulcers from Helicobacter pylori (H pylori) infection | Early research suggests that taking berberine three times daily for six weeks is more effective than the drug ranitidine at eliminating H. pylori infection but lacks efficacy at healing ulcers in people with stomach ulcers due to H. pylori. |
| Trachoma | There is some data that eye drops with berberine might help treat trachoma, a common reason for blindness in developing countries. |
How much berberine should I take daily?
The right berberine dosage can make a big difference in how it benefits your health. Generally, the daily dosage falls between 900 and 2000 mg, but here’s how to approach it more precisely:
- Aim for a daily total of 900 to 1500 mg, which aligns with most research studies.
- Since berberine’s action in the body doesn’t last long, divide this total into two or three doses to maintain steady levels throughout the day.
- It’s often recommended to take berberine before meals. This timing can help with absorption and may reduce the risk of stomach upset.
- If you’re new to berberine, consider starting with a lower dose (such as 300 mg per day) and gradually increasing. This can help your body adjust and minimize potential side effects [5].
Remember, what works for one person might not work for another, so it’s essential to listen to your body and consult with a healthcare provider to tailor the dosage to your specific needs.
Drug interactions that need attention
It’s always best to discuss with your health practitioner prior to starting any supplements, especially if you’re currently taking other drugs:
Cyclosporine (Neoral, Sandimmune): This interaction can increase cyclosporine levels in the blood, potentially leading to toxicity [6]. It’s crucial for individuals taking cyclosporine to consult their healthcare provider before starting berberine, ensuring adjustments can be made to avoid adverse effects.
Medications for diabetes (Antidiabetes drugs): Taking berberine alongside medications such as metformin, insulin, or sulfonylureas can enhance their effects, potentially leading to hypoglycemia. Always consult with a healthcare provider before combining berberine with any diabetes medications to adjust dosages appropriately and ensure safe blood sugar levels.
Dextromethorphan (Robitussin DM, and others): Berberine can affect how your body processes certain medications, including Dextromethorphan, commonly found in cough suppressants like Robitussin DM [7].
This interaction may lead to higher levels of the drug in your bloodstream, potentially increasing side effects. If you’re using Dextromethorphan, consult your healthcare provider before starting berberine to discuss any necessary adjustments to your medication regimen.
Losartan (Cozaar): It may enhance the drug’s effects, potentially leading to excessively low blood pressure. If you’re considering berberine and you’re on Losartan, it’s crucial to consult your healthcare provider to adjust dosages appropriately and monitor your blood pressure closely to ensure safety.
Berberine is one of the several supplements that are as effective as a drug. It strongly affects various aspects of health, especially blood sugar control.
The individuals who benefit the most are those with type 2 diabetes and metabolic syndrome.
Nevertheless, it may also be helpful as a general defense against chronic disease, as well as an antiaging supplement. If you use supplements, berberine may be one of the top ones to include in your arsenal.
