Spotlight on the Plant Compound Berberine


Berberine, a bitter yellow plant extract shown to help improve glycemic control

As the incidence of health issues related to insulin resistance and carbohydrate sensitivity continues to skyrocket we need all the tools we can get to help improve the health of people affected by these multifaceted conditions. Something receiving increased recognition for its impressive efficacy in affecting multiple parameters of metabolic health is a bitter yellow plant extract called berberine. Berberine is so effective in fact that studies have shown it to be at least as effective as the commonly prescribed drug metformin for helping improve glycemic control.

Berberine supplementation may help improve insulin-related health issues

Health issues related to insulin resistance are often accompanied by elevated fasting blood sugar and insulin levels elevated hemoglobin A1c (a longer-term marker for blood sugar control) elevated post-meal blood sugar elevated LDL-cholesterol and elevated blood fats (triglycerides). Berberine has shown promise in affecting all of these factors without some of the unpleasant side-effects of pharmaceutical drugs.123 These effects are quite significant and berberine may be especially helpful for people whose blood sugar woes remain poorly controlled despite a healthy diet, exercise, and an appropriate medication regimen. For those who are doing “all the right things” but still don’t experience the expected improvements in health berberine might be a powerful ally.   Of course, these individuals need to work with their doctors when adding berberine to their nutrition regimens.

How berberine can be an aid for the body to use insulin effectively

As for how berberine exerts these effects there are multiple mechanisms. One of them is that berberine may help the body secrete more insulin and also use that insulin more effectively. Besides aiding the body in producing more insulin berberine also helps to increase the amounts and efficiency of insulin receptors. Insulin can only do its job of escorting glucose into the cells when there are properly functioning insulin receptors available to receive it. So berberine may support better glycemic control on two fronts: enhancing the production of insulin as well as facilitating proper usage of the hormone.

Berberine for carbohydrate intolerance

Another way berberine may help with carbohydrate intolerance is by inhibiting the action of some of the intestinal enzymes involved in digesting carbohydrates. In animal studies, berberine has been shown to reduce the duration of elevated blood sugar after the animals were dosed with sucrose and maltose—two types of sugar that are broken down in the small intestine.

Berberine potency similar to statin drugs without the negative side-effects

Aside from its powerful effects on glycemic control berberine has also demonstrated the ability to favourably impact blood lipids (cholesterol and triglycerides). Unlike statin drugs however berberine does not affect the complex pathway by which the body produces cholesterol internally and therefore does not present the many undesirable side-effects linked to statins.

Berberine may help reduce low-density lipoproteins

The way berberine may help reduce LDL is similar to the way it helps insulin work better—it helps to increase the expression of LDL receptors. Like insulin, LDL particles can’t perform their function of delivering cholesterol to cells unless there are functional LDL receptors on which they can “dock” like a ship arriving in a port to deliver cargo.

As mentioned earlier it is important for individuals to work closely with their health care practitioners when considering such compounds as berberine. Opening the line of communication with practitioners is the key to addressing one’s health in a comprehensive and educated way.
