In the event you’ve been coping with excessive blood sugar or a situation like kind 2 diabetes—or polycystic ovary syndrome (PCOS), then you definitely in all probability have heard of metformin. It is a quite common treatment that medical doctors use to assist sufferers decrease blood glucose ranges and enhance insulin sensitivity. But it surely does have widespread unwanted effects like abdomen upset and diarrhea, which make it laborious 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 1000’s 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 referred to as “pure metformin” as a result of it appears to work in related methods. It helps to regulate blood sugar, makes insulin work higher, improves ldl cholesterol, and even helps weight administration. However is it actually nearly 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 will clarify why berberine’s low absorption could be a downside. And we’ll check out outcomes from one of many new variations—second era 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 break up the volunteers into three teams:
– Among the newly identified folks acquired berberine or metformin alone.
– For the individuals who already had diabetes however have been poorly managed, they merely added berberine to the standard medicines like insulin or different capsules.
Everybody took 500 mg of the remedy thrice a day with their meals for 3 months. And the outcomes? Effectively, they have 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 may check out the graph beneath and see that it does not look a lot completely different for berberine or metformin.

After-meal sugar spikes additionally improved loads in each instances with berberine and metformin, displaying that insulin sensitivity was improved and pancreatic operate was significantly better.
So blood sugar outcomes have been very related with berberine and metformin, however there’s extra. Berberine additionally beat metformin in serving to with different danger components for heart problems. Triglycerides have been down by 21% with berberine in comparison with virtually no change with metformin.
Berberine additionally dropped complete ldl cholesterol by 13%, with LDL ldl cholesterol going decrease too. Within the group that added berberine to their different medicine, insulin resistance improved by almost 45%, utilizing a rating referred to as HOMA-IR, and waist measurement shrunk with out massive weight reduction. This exhibits that berberine was serving to combat stomach fats, which is an enormous danger for coronary heart illness.
And the unwanted effects? About 35% of the folks had gentle GI troubles like fuel or unfastened stools, however these pale after a couple of weeks and nobody had liver or kidney issues. The researchers referred to as berberine a “potent oral hypoglycemic agent“—so berberine is likely to be an awesome various for many who are taking metformin, they usually’re more likely 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 awesome research with ladies who’ve polycystic ovary syndrome (PCOS). This can be a situation that impacts as much as 1 in 10 ladies of childbirth age. It causes irregular intervals, extra hair, pimples, and fertility points, all because 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 ladies aged 15 to 40. Every group acquired 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 beneficial change in food regimen or train to restrict the outcomes to simply what was being examined.
Effectively, it seems that the researchers picked three winners: berberine, metformin, and myoinositol—all of them labored. However for some facets 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 measurement, berberine received 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 greatest, falling 46% versus 22% for berberine.
Hormone Enhancements with Berberine
Effectively, 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 properly.
Further 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 complete 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 decreasing triglycerides, scoring a few 33% drop. General, the research confirmed that berberine matched metformin’s traditional advantages, but additionally had additional advantages for physique form, enhancing hormones, and reducing coronary heart illness dangers.
Three ladies stop metformin due to intestine points, versus none on berberine. The pure berberine remedy might be gentler for some folks.
Berberine: 3 Causes Why Isn’t It Extra Standard
If berberine is so good, why is not all people taking it? Effectively, the very first thing is that there are extra salesmen pushing metformin as a pharmaceutical than berberine as a pure complement. There is not almost 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 almost as a lot cash behind berberine as a pure complement to check it time and again in research to indicate that it has the identical impression. This makes medical doctors extra hesitant to belief and check out berberine with their sufferers.
There are some good research, however there usually are not close to as many as you’d discover with metformin. I actually wouldn’t have realized how properly berberine labored till I heard a remark about “pure metformin” that prompted me to take a look at the claims extra fastidiously.
The third subject 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 mass the place it may 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. After all, you break up it up and take it with meals, which helps with unwanted effects. However that is a whole lot of berberine left in your intestine, and that may trigger irritation, comparable 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.
Make Berberine Higher
Scientists have appeared for a method 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 form 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-Based mostly Complementary and Various Drugs examined berberine phytosome with wholesome folks. The results of taking the phytosome kind was a 8 or 9-fold enhance in complete berberine absorption, and a 5 or 6-fold enhance in free berberine bioavailability. (See the Determine beneath.) And the doses wanted have been a lot decrease to get this enhance.

In 2023, researchers took this phytosome berberine formulation and did a research in Pakistan with 130 ladies battling 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 ladies largely had irregular menstrual cycles, however they did not have bother with blood sugar ranges or lipids. These have been regular. The outcomes confirmed that berberine does much more than simply normalize blood sugar and lipid ranges.
Within the ladies taking the berberine, their pimples cleared up quicker. The intervals have 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 ladies who had not been capable of get pregnant conceived whereas taking berberine. Nice outcomes, displaying that berberine, when sufficient of it acquired 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 already know that you’ve got another. 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 various to metformin.
After all, 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 finally drive down fatty liver (causes excessive fasting blood glucose) and fat-inhibited pancreatic motion. However in the meantime, in order for you a little bit assist to get higher outcomes quicker, it is best to discuss to your well being care supplier about utilizing berberine. It is likely to be an awesome choice for you.
