The mechanism for berberine extract is very unclear. For decades it has been a well-researched herbal treatment for intestinal infections, like Giardia, but it came with the warning to avoid long-term use due to the potential undesirable and antimicrobial effect in the gut.
Findings revealed that treatment of 300 mg of Berberine three times a day for 12 weeks resulted in a significant reduction of 5.2 cm in waist circumference. Berberine has the potential to reduce belly fat after 12 weeks of treatment. Significantly, all participants did not change their lifestyle during the study.
The absorption of berberine gradually increased with incubation time up to 90 min, and it was absorbed at various intestinal segments although the absorbed dose was small. Absorption was the greatest in the jejunum, followed by the duodenum and ileum.
The effects of berberine are not immediately felt if you take it for only a few days. Instead, taking it for more extended periods is necessary to see its effects. Some studies suggest that berberine's effects can be seen when taking supplements for at least three months.

In one study, individuals who were obese participated in 12-week research and took 500 mg of berberine three times a day [6]. Investigators found out that the participants lost an average of 5 pounds. In addition, the participants lost 3.6% of their body fat.
Berberine can induce cell death of harmful intestinal bacteria and increase the number and species of beneficial bacteria (Habtemariam, 2020).
Emerging research suggests that berberine is beneficial for balancing hormones, especially when it comes to polycystic ovary syndrome (PCOS). Berberine provides numerous benefits for women living with PCOS, including improved fertility, weight loss, and reduced inflammation.
Despite wide scale use as an herbal supplement, berberine has not been linked to published instances of clinically apparent liver injury.
The toxicity of pure compound is greater than the toxicity of plant extract or plant extract fractions. The sub-acute concentrations of berberine lead to altered liver function, gastric troubles, hepato and hematotoxicity, hemorrhagic inflammatory consequences, damage to immune cells and induced apoptosis.
Research has suggested that berberine can help treat diabetes, obesity, and inflammation, among other conditions. However, side effects can include upset stomach and nausea. Berberine has been a part of Chinese and Ayurvedic medicine for thousands of years.
Early research suggests that taking berberine together with vitamin D3, vitamin K, and a chemical found in hops for 14 weeks can decrease bone loss in postmenopausal women with osteoporosis.

This study showed that berberine, a natural drug with low oral availability, significantly ameliorated chronic kidney disease by altering the composition of the gut microbiota and inhibiting the production of gut-derived uremic toxins, including p-cresol.
