Berberine for PCOS – 12 Great Reasons to Take It

Supplements are an important part of your PCOS management plan. And one of the more common supplements is Berberine. If you have been thinking about starting berberine for PCOS, look no further.

Before we get on to how Berberine can help with your PCOS symptoms, we need to understand what it is…


What is Berberine?

Berberine for PCOS - chinese medicineAs a natural plant alkaloid, berberine is found in a variety of plants, but most commonly in the roots and stems of certain barberry species.

The Chinese have been using it as a herbal medicine for over 3000 years, and it’s been gaining popularity in the Western world as well.

So, what does berberine do?

Berberine has many properties that make it beneficial for health, but the two main ones are its ability to lower blood glucose and its anti-inflammatory effects.

Here are 10 ways berberine can help you manage your PCOS symptoms.


Berberine for PCOS

One of the main problems with PCOS is that there is some irregularities in the insulin signaling pathway. This means that we tend to produce too much insulin which can lead to metabolic disorders, as well as a lot of the unpleasant symptoms of PCOS.

One of the ways that berberine works is to lower insulin and glucose levels which can help to improve a lot of the symptoms of PCOS.

Here are some of the ways that Berberine treatment may help your PCOS:

  • Reduces Insulin ResistanceBerberine for PCOS - thumbs up
  • Lowers Blood Sugar Levels
  • Aids in Weight Loss
  • Improves Cholesterol Levels
  • Regulates Menstrual Cycles
  • Reduces Inflammation
  • Helps Restore Hormonal Balance
  • Improves Fertility
  • Helps Combat Depression
  • Helps Fight Fatty Liver Disease
  • Alleviates some of the Symptoms of Menopause
  • Improves Body Composition
  • Reduces Insulin Resistance

We know that women with Polycystic Ovary Syndrome are prone to insulin resistance. In fact, it is one of the main causes of a lot of our pesky PCOS symptoms.

Berberine improves insulin sensitivity and has been shown to help lower blood glucose levels. One study showed that after 12 weeks of taking Berberine, women with polycystic ovary syndrome showed improved insulin sensitivity (1).

This is exciting news for those of us with PCOS because it means that we can potentially get our symptoms under control without having to resort to medication.




Lowers Blood Sugar Levels

Berberine for PCOS - blood sugarInsulin’s job is to transport sugar from the bloodstream into our cells, where it can be used for energy. But when we are insulin resistant, this process doesn’t work as it should, and sugar builds up in our blood instead.

This leads to high plasma glucose levels, which is not only dangerous in the long run but can also cause PCOS symptoms like metabolic syndrome, fatigue, weight gain, and brain fog.

Berberine has been shown to help lower blood sugar levels by improving insulin sensitivity and increasing glucose uptake – the amount of sugar taken up by cells.


Aids in Weight Loss

Berberine for PCOS - weight lossWe know that Berberine helps with glucose metabolism in women with PCOS. The great news is that this can also lead to weight loss.

One clinical study of 37 people who had been diagnosed with metabolic syndrome showed that 12 weeks of treatment with Berberine resulted in weight loss, improved metabolic characteristics and a lowered body mass index (2).

In fact, this particular study showed that the average body mass index went from 31.5 to 27.4 after 12 weeks of berberine use.

It’s thought that berberine works by reducing fat storage, increasing energy expenditure and improving insulin sensitivity.

So, if you’re looking to lose weight, berberine could be a helpful addition to your PCOS management plan.


Improves Cholesterol Levels

Berberine for PCOS - cholesteroljpgWomen with polycystic ovary syndrome are also at an increased risk of developing cardiovascular disease. This is due to a combination of factors, including insulin resistance, inflammation, and hormonal imbalances.

Berberine has been shown to help improve cholesterol levels and lipid metabolism by reducing low density lipoprotein cholesterol or LDL (bad cholesterol) and triglycerides while increasing high density lipoprotein cholesterol or HDL (good cholesterol).

One study showed that berberine was just as effective as the cholesterol-lowering drug simvastatin in reducing LDL levels (3).

Another study showed that berberine improved lipid profiles in women with PCOS. After 8 weeks of treatment, the women had significantly lower levels of triglycerides, total cholesterol, and LDL cholesterol (4).

If you are struggling with high cholesterol levels, berberine may be the novel cholesterol lowering drug you have have been looking for.


Regulates Menstrual Cycles

Berberine for PCOS - menstrual cycleA healthy menstrual cycle is important for fertility, and berberine has been shown to help regulate cycles in women with PCOS.

One study showed that berberine improved ovulation rates in women with PCOS.

In another study, published in the Journal of Clinical Endocrinology, 100 women with PCOS were given either berberine or metformin (a common PCOS medication) for 3 months. The results showed that both treatments improved ovulation rates and menstrual regularity.

But what’s even more exciting is that the women who were treated with berberine had significantly higher levels of sex hormone binding globulin than the women who were treated with metformin (5).

This is important because higher levels of sex hormone binding globulin will help to lower overall testosterone levels (or the free androgen index) and can also help to prevent gestational diabetes when you are pregnant (6).

So, if you’re looking for a natural way to regulate your cycles and reduce testosterone levels, berberine could be a good option.


Reduces Inflammation

Berberine for PCOS - inflammationInflammation is thought to play a role in the development of PCOS. And, as we mentioned before, women with PCOS are also at an increased risk of developing cardiovascular disease.

Also, inflammation and insulin resistance are closely linked – the more inflamed you are, the more insulin resistant you are likely to be

Berberine has been shown to help reduce inflammation by inhibiting the production of pro-inflammatory cytokines. It also acts as anti-oxidant – something that can help to improve egg quality in women with PCOS.


Helps Restore Hormonal Balance

Berberine for PCOS - hormone balanceAs we mentioned before, PCOS is often characterized by hormonal imbalances. And, while there is no “cure” for PCOS, restoring hormonal balance is an important part of managing the condition.

Berberine has been shown to help restore hormonal balance by reducing androgen levels and increasing progesterone levels.

Also, remember that studies have shown that berberine lowered insulin levels and if we can lower insulin levels, we will see an overall improvement in our PCOS symptoms.

One study showed that berberine was able to significantly lower androgen levels in women with PCOS (7).

Another study showed that, after 3 months of treatment with berberine, the women had significantly higher progesterone levels and a decrease in the luteinizing hormone to follicle stimulating hormone ratio (8).

So, what does this mean for you? If you can address the underlying hormonal imbalance we so often see in polycystic ovary syndrome (PCOS), you should see an improvement in all of your PCOS symptoms, not just one or two.


Improves Fertility

Berberine for PCOS - fertilityIf you’re trying to conceive, then improving fertility is likely a top priority. And, as we mentioned before, one of the main causes of infertility in women with PCOS is anovulation (the absence of ovulation).

Berberine has been shown to help improve ovulation rates in women with PCOS. Interestingly, it also improved endometrial receptivity. This is basically improving the process of implantation of the embryo.

So, if you’re trying to get pregnant, berberine could be a helpful supplement to take.


Helps Combat Depression

Berberine for PCOS - depressionDepression and anxiety are some of the least spoken about symptoms of polycystic ovarian syndrome but they are very real and can have a massive impact on your quality of life.

There is a growing body of evidence that shows that berberine treatment can improve both depression and anxiety (9).


Helps Fight Fatty Liver Disease

Berberine for PCOS - NAFLDNAFLD or non alcoholic fatty liver disease is another condition that is often seen in women with PCOS. In fact, we have are four times more likely to develop NAFLD than women without PCOS (10)

That is why you may want to consider liver function tests as part of your regular PCOS check up.

The good news is that Berberine has been shown to be an effective treatment for NAFLD. It works by reducing triglyceride levels, improving insulin sensitivity, and reducing inflammation. (11)


Alleviates some of the Symptoms of Menopause

Berberine for PCOS - menopauseAs estrogen levels decline during menopause, we become more at risk to a whole host of other medical issues.

Some of these include:

  • Cardiovascular disease
  • Type 2 diabetes mellitus and impaired glucose tolerance
  • Depression

As you can see from everything we have already spoken about, berberine is an insulin sensitizer and has been shown to have beneficial metabolic effects which can help to combat some of the symptoms seen in menopause (12).


Improves Body Composition

Berberine for PCOS - body compositionIn some clinical trials, PCOS patients were shown to have an improved body composition when taking berberine.

In particular, one study showed a decrease in waist circumference, even if the women involved in the study did not lose weight. This is important as it shows the effect of berberine on visceral fat (fat that surrounds the organs).

So, you can see that Berberine has a whole host of benefits for women with PCOS and it may well be a supplement that you would like to add to your daily supplement regime.
