GLP-1 Nature’s Weight Loss

Studies have identified over 42% of Americans are obese. The scope of the U.S. weight demographic explains the explosion of sales of GLP-1 drugs with 12% of the population trying the drugs. Although significant weight-loss results have been identified, 50% of consumers stop using the GLP-1 prescribed drug in the first year with another 25% of patients ceasing its use by the second year, resulting in 75% of consumers ending the use of their prescriptions. As a result consumers have experienced their weight returning.

Studies have shown a range of side effects and even serious complications as a result of the currently approved GLP-1 drugs.1 The documented side effects are predominantly gastrointestinal, and include nausea, diarrhea, constipation, vomiting and include a loss of muscle mass. There are reported adverse events, that include gallbladder disorders and acute pancreatitis.2 In addition, multiple studies identified new risks associated with GLP-1RAs including increased aspiration risk during anesthesia due to delayed gastric emptying and bowel preparation for colonoscopies.

Recent studies on gut bacteria Akkermansia muciniphila have demonstrated its influence on GLP-1 natural production and weight loss.3  Research has also suggested that berberine, a naturally occurring compound in several plants may stimulate the release of GLP-1 and help improve glycemic control, reduce appetite, and support weight loss, making it a promising supplement for managing type 2 diabetes and metabolic disorders.4 Its combination of effects on glucose metabolism and GLP-1 release makes berberine a valuable natural option for metabolic health.

Berberine May Reduce Weight and Lower Blood Glucose Levels

Berberine is a substance found in plants including goldenseal, barberry, Oregon grape, and others. It has a long history of uses in ancient medicine for skin diseases, infections, and digestive health.  More recently Berberine has been studied for its effects on diabetes and risk factors for heart disease and most recently, it has become popular as a potential weight loss aid.1 

A 2022 review of 18 studies that examined the effect of berberine on body weight and 23 that examined its effect on body mass index (BMI; a value based on weight and height that may help determine whether a person has a healthy weight) found significant decreases in both weight and BMI in people who took berberine. Although more studies are needed, the effects on weight were seen primarily in people who took berberine in doses of more than 1 gram per day and for more than 8 weeks.2

In general, when taken orally, berberine is well tolerated; however, it is not without its risks and side effects. The most common adverse effects of berberine include abdominal pain, constipation, diarrhea, nausea, and vomiting. People who are pregnant or breastfeeding should not use berberine, and it should not be given to infants. Berberine can cause or worsen jaundice in newborn infants and could lead to a life-threatening problem called kernicterus. Berberine might also interact with medicines in negative ways.3

There is some evidence that berberine may have a modest effect on lowering blood glucose levels in people with type 2 diabetes and may reduce cholesterol levels. Berberine may have additional beneficial effects on high blood pressure when used in combination with the medication amlodipine.
