Are you looking for a natural solution to shed some pounds, lower your blood sugar, and boost your heart health? If so, you may want to consider berberine weight loss. Berberine is a powerful plant compound that has been used for centuries in traditional Chinese medicine. But what exactly is berberine, how does it work, and what are the benefits and side effects of taking it? In this article, we will explore these questions and more.
What is berberine and where does it come from?
Berberine is a type of alkaloid, which is a chemical substance that can affect how humans and other living things function.
- Other well-known alkaloids include morphine, nicotine, and caffeine.
- Berberine comes from various plants, such as barberry, goldenseal, Oregon grapes, and coptis.
- These plants have long been used in traditional medicines to treat a wide variety of illnesses, such as eye conditions, diarrhea, jaundice, and acne.
How does berberine weight loss work?
When you take berberine as a pill or powder, it enters your bloodstream and travels to your cells, binding to different molecules. But instead of producing a single change, berberine interacts with multiple targets, impacting more than one disease at a time. “Berberine works at a cellular level and changes how cells work by turning things off and on,” says functional medicine specialist Elizabeth Bradley, MD. “Its basic interactions involve so many different processes in the body.”
Some of the main processes that berberine affects are:
- Insulin sensitivity: Berberine can help improve insulin sensitivity by activating an enzyme called AMP-activated protein kinase (AMPK), which regulates how cells use energy. AMPK can lower blood sugar levels by increasing glucose uptake by muscles and reducing glucose production by the liver. AMPK can also reduce fat accumulation by inhibiting lipogenesis (fat synthesis) and stimulating lipolysis (fat breakdown).
- Gut microbiota: Berberine can help modulate gut microbiota by altering their composition and function. Berberine can increase the abundance of beneficial bacteria, such as Akkermansia muciniphila, which can improve metabolic health and prevent weight gain. Berberine can also reduce the activity of harmful bacteria, such as Escherichia coli, which can cause intestinal infections.
- Glucagon-like peptide 1 (GLP-1): Berberine can increase GLP-1 levels by inhibiting an enzyme called dipeptidyl peptidase-4 (DPP-4), which degrades GLP-1. By increasing GLP-1 levels, berberine can enhance insulin secretion and reduce food intake.
What are the benefits of taking berberine for weight loss?
The benefits of berberine show potential for anyone diagnosed with type 2 diabetes or metabolic syndrome — a collection of risk factors that make you more likely to develop serious health issues like diabetes, heart disease, and stroke. “Berberine can help diabetes, high blood pressure and lipid levels,” notes Dr. Bradley. “Combine berberine with lifestyle changes, like losing weight, and it can positively affect those conditions.”
Some of the benefits of taking berberine based on scientific evidence are:
- Weight loss: A meta-analysis and review of 13 clinical trials showed that taking berberine supplements led to an average weight loss of 2.3 kg (5 lbs) compared to placebo. Another meta-analysis of 27 randomized controlled trials found that berberine reduced body mass index (BMI) by 0.9 kg/m2 and waist circumference by 1.97 cm compared to placebo.
- Blood sugar control: A meta-analysis of 14 randomized controlled trials showed that taking berberine supplements lowered fasting blood glucose by 0.9 mmol/L, postprandial blood glucose by 1.9 mmol/L, and glycated hemoglobin (HbA1c) by 0.8% compared to placebo. Another meta-analysis of 27 randomized controlled trials found that berberine reduced fasting blood glucose by 0.6 mmol/L, postprandial blood glucose by 1.3 mmol/L, and HbA1c by 0.5% compared to placebo.
- Cholesterol and triglyceride levels: A meta-analysis of 15 randomized controlled trials showed that taking berberine supplements lowered total cholesterol by 0.61 mmol/L, low-density lipoprotein (LDL) cholesterol by 0.65 mmol/L, and triglycerides by 0.50 mmol/L compared to placebo. Another meta-analysis of 27 randomized controlled trials found that berberine reduced total cholesterol by 0.61 mmol/L, LDL cholesterol by 0.65 mmol/L, and triglycerides by 0.35 mmol/L compared to placebo.
- Blood pressure: A meta-analysis of nine randomized controlled trials showed that taking berberine supplements lowered systolic blood pressure by 4.9 mmHg and diastolic blood pressure by 3.6 mmHg compared to placebo. Another meta-analysis of 27 randomized controlled trials found that berberine reduced systolic blood pressure by 4.18 mmHg and diastolic blood pressure by 2.6 mmHg compared to placebo.
The table below summarizes the effects of berberine on various metabolic parameters compared to placebo based on the meta-analyses mentioned above:
| Parameter | Effect size | Number of studies |
|---|---|---|
| Weight loss (kg) | -2.3 | 13 |
| BMI (kg/m2) | -0.9 | 27 |
| Waist circumference (cm) | -1.97 | 27 |
| Fasting blood glucose (mmol/L) | -0.75 | 41 |
| Postprandial blood glucose (mmol/L) | -1.6 | 41 |
| HbA1c (%) | -0.65 | 41 |
| Total cholesterol (mmol/L) | -0.61 | 42 |
| LDL cholesterol (mmol/L) | -0.65 | 42 |
| Triglycerides (mmol/L) | -0.43 | 42 |
| Systolic blood pressure (mmHg) | -4.54 | 36 |
| Diastolic blood pressure (mmHg) | -3.1 | 36 |
What are the side effects of taking berberine for weight loss?
Berberine is generally well-tolerated, but it may cause some side effects, such as:
- Gastrointestinal discomfort: Berberine may cause nausea, diarrhea, constipation, bloating, gas, and stomach pain in some people. These side effects may be reduced by taking berberine with food or lowering the dose.
- Low blood sugar: Berberine may lower blood sugar levels too much in some people, especially if they are taking other medications or supplements that lower blood sugar, such as metformin, insulin, or cinnamon. This may cause symptoms such as dizziness, sweating, shakiness, hunger, and confusion. To prevent this, monitor your blood sugar levels regularly and adjust your dose accordingly.
- Drug interactions: Berberine may interact with some medications, such as anticoagulants, antidepressants, antibiotics, antifungals, antivirals, statins, and cyclosporine. These interactions may increase or decrease the effectiveness or side effects of these medications. To avoid this, consult your healthcare provider before taking berberine or any other supplement.
How to take berberine weight loss?
The optimal dose of berberine for weight loss and other benefits is not clear, but most studies have used doses ranging from 100 mg to 500 mg per day. Some experts suggest taking berberine in divided doses before meals to maximize its absorption and effectiveness.
However, the dose of berberine may vary depending on your individual needs and goals, as well as your tolerance and response to the supplement. Therefore, it is best to start with a low dose and gradually increase it until you find the optimal dose for you.
Some tips for taking berberine are:
- A common starting dose is 100 mg per day, taken before breakfast.
- You can then increase the dose by 100 mg every week until you reach 500 mg per day, which is the upper limit recommended by most experts.
