Berberine and Heart Failure

Posted on by

An interesting article showing the connection between berberine and congestive heart failure. Note the importance of a good quality supplement in order to achieve relevant blood levels. Here is a portion of the abstract from the study:

It has been reported that berberine is valuable for long-term treatment of ventricular premature beats (VPBs) and leads to a decrease in mortality for patients with congestive heart failure (CHF). In order to improve its therapeutic value and reduce its side effects, it is necessary to study the relationship between its activity and plasma concentration in patients with CHF. Patients with CHF were treated with conventional therapy for 2 weeks. Immediately after the data from a dynamic electrocardiogram (DCG) and left ventricular ejection fraction (LVEF) were obtained, 1.2 g/day of oral berberine was given. After 2 weeks of berberine therapy, the DCG data and LVEF were reassessed and the plasma berberine concentration was measured by HPLC. Plasma samples were pretreated by extraction with chloroform. The decrease in frequency and complexity of VPBs and the increase in LVEF in patients with plasma berberine concentrations higher than 0.11 mg/L (n = 31, group B) were more significant than at concentrations lower than 0.11 mg/L (p < 0.01 vs p < 0.05).

Berberine and Diabetes

Posted on by

Berberine is the most studied natural substance showing positive effects on sugar control. Here is an abstract summary from a recent study showing a beneficial effect of berberine in diabetes both as far as the glucose and the blood fats are concerned:

Berberine, a natural  plant  alkaloid,  is usually used as an antibiotic drug. The potential glucose-lowering effect of berberine was noted when it was used for diarrhea in diabetic patients. In vitro and in vivo studies have then showed its effects on hyperglycemia  and dyslipidemia. Objective: The objective of the study was to evaluate the efficacy and safety of berberine  in the treatment of type 2 diabetic patients with  dyslipidemia. Design: One hundred  sixteen patients with  type 2 diabetes and dyslipidemia  were randomly  al- located to receive berberine (1.0 g daily) and the placebo for 3 months. The primary outcomes were changes in plasma glucose and serum lipid concentrations. Glucose disposal rate (GDR) was mea- sured using a hyperinsulinemic euglycemic clamp to assess insulin sensitivity. Results: In the berberine group, fasting and postload plasma glucose decreased from 7.0 ± 0.8 to 5.6 ± 0.9 and from 12.0 ± 2.7 to 8.9 ± 2.8 mM/liter, HbA1c from 7.5 ± 1.0% to 6.6 ± 0.7%, triglyceride from 2.51 ± 2.04 to 1.61 ± 1.10 mM/liter, total cholesterol from 5.31 ± 0.98 to 4.35 ± 0.96 mM/liter, and low-density lipoprotein-cholesterol from 3.23 ± 0.81 to 2.55 ± 0.77 mM/liter, with  all param- eters differing from placebo significantly (P < 0.0001, P < 0.0001, P < 0.0001, P = 0.001, P < 0.0001, and P <0.0001, respectively). The glucose disposal rate was increased after berberine  treatment (P = 0.037), although no significant change was found between berberine and placebo groups (P = 0.063). Mild to moderate  constipation was observed in five participants in the berberine  group. Conclusions: Berberine is effective and safe in the treatment of type 2 diabetes and dyslipidemia.
