Should you’ve been coping with excessive blood sugar or a situation like kind 2 diabetes—or polycystic ovary syndrome (PCOS), then you definately most likely have heard of metformin. It is a quite common treatment that docs use to assist sufferers decrease blood glucose ranges and enhance insulin sensitivity. But it surely does have widespread unintended effects like abdomen upset and diarrhea, which make it arduous to keep it up. Are there options? Sure. How about berberine? It’s a bitter, yellow compound from vegetation like Barberry and Goldenseal.
Berberine has been utilized in Chinese language and Ayurvedic drugs for hundreds of years to deal with infections and digestive points and to assist with blood glucose. The Chinese language have used it for diabetes for so long as there’s been diabetes in China. In some circles it’s known as “pure metformin” as a result of it appears to work in comparable methods. It helps to regulate blood sugar, makes insulin work higher, improves ldl cholesterol, and even helps weight administration. However is it actually pretty much as good? And whether it is that good, why is not everybody switching to it?
We’ll check out two key research that examine berberine head-to-head with metformin. Then I am going to clarify why berberine’s low absorption is usually a downside. And we’ll check out outcomes from one of many new variations—second technology berberine formulation that make it gentler in your physique.
Berberine as a Pure Metformin: 2008 Examine
The oldest research that I discovered with a comparability of berberine and metformin is from 2008. The journal Metabolism revealed a research from researchers in China. They examined berberine in a head-to-head competitors with metformin in a research with 84 adults that had kind 2 diabetes.
They cut up the volunteers into three teams:
– Among the newly recognized individuals received berberine or metformin alone.
– For the individuals who already had diabetes however had been poorly managed, they merely added berberine to the standard medicines like insulin or different drugs.
Everybody took 500 mg of the remedy 3 times a day with their meals for 3 months. And the outcomes? Properly, they had been spectacular for berberine! Within the new diabetes group, berberine dropped common blood sugar, as measured by HbA1c, from 9.5% to 7.5%. It is about the identical as what you noticed with metformin, which went from 9.2% to 7.7%.
Fasting blood sugar additionally fell within the berberine group from 10.6 mmol/L to six.9 mmol/L. That was about the identical as what was seen with metformin. You’ll be able to check out the graph beneath and see that it does not look a lot totally different for berberine or metformin.

After-meal sugar spikes additionally improved so much in each circumstances with berberine and metformin, displaying that insulin sensitivity was improved and pancreatic perform was significantly better.
So blood sugar outcomes had been very comparable with berberine and metformin, however there’s extra. Berberine additionally beat metformin in serving to with different danger elements for heart problems. Triglycerides had been down by 21% with berberine in comparison with virtually no change with metformin.
Berberine additionally dropped whole ldl cholesterol by 13%, with LDL ldl cholesterol going decrease too. Within the group that added berberine to their different medication, insulin resistance improved by practically 45%, utilizing a rating known as HOMA-IR, and waist dimension shrunk with out massive weight reduction. This exhibits that berberine was serving to struggle stomach fats, which is a giant danger for coronary heart illness.
And the unintended effects? About 35% of the individuals had delicate GI troubles like gasoline or unfastened stools, however these light after a couple of weeks and nobody had liver or kidney issues. The researchers known as berberine a “potent oral hypoglycemic agent“—so berberine may be an incredible different for individuals who are taking metformin, they usually’re prone to get even higher outcomes.
Berberine for PCOS: 2022 Examine
I do not know what occurred in all of the years between 2008 and 2022, however lastly there’s an incredible research with girls who’ve polycystic ovary syndrome (PCOS). It is a situation that impacts as much as 1 in 10 girls of childbirth age. It causes irregular intervals, extra hair, pimples, and fertility points, all as a consequence of hormone imbalances and insulin resistance.
So in 2022, this trial from India in contrast berberine, metformin, and myoinositol, which is a helper-like vitamin for insulin. The trial included 129 girls aged 15 to 40. Every group received their remedy twice a day for 3 months—500 mg twice a day for berberine, or 500 mg twice a day for metformin, or 1000 mg twice a day of myoinositol. There was no advisable change in weight-reduction plan or train to restrict the outcomes to simply what was being examined.
Properly, it seems that the researchers picked three winners: berberine, metformin, and myoinositol—all of them labored. However for some features berberine truly labored higher. Physique weight dropped about 4 kilograms within the berberine and metformin teams, and a pair of kilograms with Myoinositol. BMI, or the Physique Mass Index, improved in all teams.
Higher Weight Administration with Berberine
However for waist dimension, berberine gained massive, shrinking it by 4 cm versus 2 cm for the others. And the waist-to-hip ratio, which is one other marker for coronary heart well being, improved probably the most with berberine too. Blood sugar and insulin improved in all of the teams. However for simply pure insulin sensitivity enhancements, myoinositol labored finest, falling 46% versus 22% for berberine.
Hormone Enhancements with Berberine
Properly, what about fixing the imbalanced hormones seen in PCOS? Whole testosterone dropped equally in all teams, however berberine boosted intercourse hormone binding globulin (SHBG, which binds up free testosterone so it causes much less signs) greater than the others, resulting in the largest drop in free androgen index. So berberine has a slight edge in hormone balancing as effectively.
Additional Advantages of Berberine: Blood Lipid Enhancements
Whereas metformin and myoinositol helped with physique weight and blood sugar points, berberine shined when it got here to blood lipids. Berberine slashed whole ldl cholesterol by 13%, dropped triglycerides by 6%, and LDL ldl cholesterol by 17%, whereas elevating the HDL ldl cholesterol stage by 5%.
This was nice, however metformin was higher on this research for reducing triglycerides, scoring a couple of 33% drop. General, the research confirmed that berberine matched metformin’s traditional advantages, but additionally had further advantages for physique form, enhancing hormones, and reducing coronary heart illness dangers.
Three girls stop metformin due to intestine points, versus none on berberine. The pure berberine remedy might be gentler for some individuals.
Berberine: 3 Causes Why Isn’t It Extra Well-liked
If berberine is so good, why is not everyone taking it? Properly, the very first thing is that there are extra salesmen pushing metformin as a pharmaceutical than berberine as a pure complement. There is not practically as a lot cash to be made with berberine, I do assume.
Second, there are much more research with metformin than there are with berberine. There is not practically as a lot cash behind berberine as a pure complement to check it again and again in research to point out that it has the identical influence. This makes docs extra hesitant to belief and take a look at berberine with their sufferers.
There are some good research, however there are usually not close to as many as you’d discover with metformin. I actually wouldn’t have realized how effectively berberine labored till I heard a remark about “pure metformin” that prompted me to take a look at the claims extra fastidiously.
The third situation is that berberine is not absorbed very well. Research present that solely 0.5% to five% will get into your bloodstream. Most of it stays in your intestinal tract—it does not attain your liver or your muscle groups the place it might truly assist with blood sugar points.
As a result of so little of it’s absorbed, you want fairly excessive doses, like 1,000 to 1,500 mg a day, to see its results. In fact, you cut up it up and take it with meals, which helps with unintended effects. However that is a whole lot of berberine left in your intestine, and that may trigger irritation, similar to bloating, cramps, and even diarrhea—which is seen in 10 to 35% of customers, particularly once they first get began.
Utilizing a decrease dose helps, however then you aren’t getting as a lot profit both.
The way to Make Berberine Higher
Scientists have seemed for a option to make berberine extra absorbable. The important thing to this has been to combine it with some lipids. Scientists name this a “phytosome.” It is type of like a liposome, however simpler to make. The result’s a strong dispersion of berberine in lecithin, pea protein, and grape seed extract. In 2021, a trial within the journal Proof-Primarily based Complementary and Different Medication examined berberine phytosome with wholesome individuals. The results of taking the phytosome type was a 8 or 9-fold improve in whole berberine absorption, and a 5 or 6-fold improve in free berberine bioavailability. (See the Determine beneath.) And the doses wanted had been a lot decrease to get this improve.

In 2023, researchers took this phytosome berberine formulation and did a research in Pakistan with 130 girls scuffling with PCOS. They in contrast a placebo management with the phytosome berberine, which delivered about 360 milligrams of berberine per day, which is about what’s seen within the higher line within the graph above (similar tablets).
These girls principally had irregular menstrual cycles, however they did not have hassle with blood sugar ranges or lipids. These had been regular. The outcomes confirmed that berberine does much more than simply normalize blood sugar and lipid ranges.
Within the girls taking the berberine, their pimples cleared up sooner. The intervals had been normalized in 70% of them versus simply 16% within the management group, anatomy of their ovaries improved in 60% of the berberine group, however solely 13% of the management group, and fertility improved with berberine. Three girls who had not been in a position to get pregnant conceived whereas taking berberine. Nice outcomes, displaying that berberine, when sufficient of it received absorbed, helped steadiness hormones in addition to blood glucose and blood lipid ranges.
Wrapping it Up
So, in case your physician is pressuring you to strive metformin, now you recognize that you’ve an alternate. Berberine, particularly the berberine phytosome, works very well. However even normal berberine has been proven to assist management blood sugar ranges and blood lipid ranges, assist normalize hormones in PCOS, and assist with weight reduction—particularly across the center. So berberine is a strong different to metformin.
In fact, you possibly can reverse your diabetes with out taking berberine in any respect. You actually simply must lose about 35 kilos of physique weight and be disciplined about following a wholesome way of life. It’s the weight reduction that can in the end drive down fatty liver (causes excessive fasting blood glucose) and fat-inhibited pancreatic motion. However in the meantime, if you need slightly assist to get higher outcomes sooner, you must speak to your well being care supplier about utilizing berberine. It may be an incredible choice for you.
