PCOS Teas: Do They Work? Here's What The Science Says

Various compounds found in tea have health benefits for women with PCOS. But the strength of the effect is small. Drinking tea has other benefits though, so it makes sense to enjoy it.

While certain PCOS teas may help a little, dietary change can be huge. The mechanisms of action are similar, but the size of the effects greatly differ.

The Best Teas For PCOS

In 2021, a team of researchers conducted a PCOS tea systematic review. They looked at all the randomized controlled trials on all kinds of PCOS tea. They also conducted a meta-analysis. This is a method of combining multiple studies to see if there’s a consistent “signal”.

The researchers found that green tea supplements and marjoram tea beverages reduced weight and improved insulin resistance in women with PCOS [1]. The effect size was small, but it was statistically significant.

Green tea and spearmint tea also appeared to reduce free testosterone levels. But the evidence supporting this finding was very limited. I explore the potential health benefits of spearmint tea for PCOS here.

The most valuable aspect of this systematic review was that only six studies met their eligibility criteria. These controlled trials all used either green tea, marjoram tea, or spearmint herbal tea. This tells us that there are very few high-quality studies investigating the health benefits of tea in PCOS populations.

Other teas may have health benefits, but only green tea, marjoram, and spearmint tea have PCOS-specific credentials. At least as far as body weight, metabolic health, and hormone parameters are concerned.

Green Tea For PCOS

It’s also worth noting that all the green tea for PCOS studies included in the meta-analysis, used supplements rather than a beverage. Because of this, it’s not clear that a hot cup of green tea will produce significant results. The dose of active ingredients may be too low.

Essentially, the green tea studies are an argument in favor of green tea supplements, rather than drinking more tea.

Other PCOS Herbal Teas

A similar argument can be made about several other PCOS-relevant teas. A 2020 literature review found a range of medicinal herbs that may help in the treatment of PCOS [2]. Many of these can be made into teas. Examples include aloe vera, chamomile, cinnamon, fennel, and many more.

This isn’t to say that other PCOS herbal teas like peppermint tea, raspberry leaf tea, and matcha don’t “work”. It’s just they don’t have meaningful studies supporting their efficacy. Any health claims should be consumed with a teaspoon of caution.

Key Takeaways

A non-biased review of the scientific literature reveals the following key takeaways:

There is very limited data showing that tea (as a beverage) is good for PCOS.

Any direct health benefits from PCOS teas are likely to be small.

Skepticism is warranted regarding any health claims made by tea salespeople.

Indirect Benefits Of PCOS Teas

Randomized controlled trials aside, there are other reasons why tea is good for PCOS. For a start, tea is hydrating. More importantly, though, tea can be a powerful ally for forming better habits.

As I’ve written about before, sugar is at the top of the list of foods to avoid with PCOS. Dairy isn’t great either. By displacing sugar and dairy-containing beverages, the health benefits of tea go well beyond the antioxidants they contain.

We can also use tea to improve our sleep and help us relax. Both of which are evidence-based PCOS natural treatments.

Diet Is The Best PCOS Treatment

So, it’s true that certain teas can help with PCOS symptoms. But the direct benefits are small.

Making other changes to your diet will get you much better results. This is because chronic inflammation and insulin resistance are underlying mechanisms that drive PCOS [3-5]. Your gut health, and the foods you eat push on these mechanisms for good or for bad.

While PCOS teas may help a tiny bit, fixing the rest of your diet can make a big difference.

Bottom Line

Green tea, marjoram tea, and spearmint tea have small direct health benefits for women with PCOS. But drinking tea has other indirect benefits too. It improves hydration and can displace other, less healthy beverages.

If you want to take back control of your health and fertility, then changing your diet is key. A PCOS-friendly diet is much more powerful than tea or tea extract supplements.
