Antioxidant Rich Spices and Herbs for PCOS


If you have PCOS, you’re probably tired of hearing about all the foods you should supposedly cut out. You rarely hear about foods you should be adding to your diet! The good news that adding in certain foods can decrease inflammation, insulin resistance, reduce oxidative stress and more. Antioxidants are “sneaky” substances found in plant foods such as fruits and vegetables, spices and seasonings that may help improve symptoms of PCOS as well as decrease long term health risks. In this blog post, nutrition student Nikki Kim takes a deep dive into the world of antioxidants, their health benefits and where to find them. Hint: you’ll learn how to incorporate delicious antioxidant rich spices and herbs into your foods! This post gets a little “sciency” but hang in there.

What are antioxidants?

You’ve probably heard of antioxidants – but what the heck are they? Antioxidants are substances that can protect your cells against “free radicals,” also known as reactive oxygen species (ROS). Free radicals are essentially unavoidable byproducts produced by cells during the normal metabolic processes, such as turning foods into energy. Your body cells naturally produce antioxidants to remove and neutralize these free radicals. Under normal conditions, the body can maintain a balance between free radicals and antioxidants. However, when there is an accumulation of free radicals and/or the antioxidant status is inadequate, a condition called oxidative stress can occur.

Oxidative stress can accelerate cell damage, negatively affecting your immune system and leading to chronic inflammation. Inflammation is a major factor that contributes to the progression of various diseases such as cancer, cardiovascular diseases, diabetes, neurodegenerative diseases and more (see the section on antioxidants and PCOS below).

Risk factors that contribute to oxidative stress:

  • Obesity
  • Excessive exercise
  • Diets high in sugar and fat
  • Smoking
  • Alcohol
  • Environmental pollution
  • Radiation  
  • Exposure to pesticides and industrial chemical

Types of antioxidants:

There are hundreds, possibly thousands, of substances that can act as antioxidants. Each substance has its own unique role and functions to fight against free radicals. Also, they are not interchangeable with one another, meaning that no single substance alone can protect your body from all harms of free radicals. Therefore, it is important to eat a wide variety of foods within each food group. Some of the familiar substances that can act as antioxidants are:

  • Vitamins A, C, and E 
  • Beta-carotene
  • Lycopene
  • Lutein
  • Selenium
  • Manganese
  • Flavonoids
  • Polyphenols
  • Phytoestrogens
  • Glutathione


Why are antioxidants important for PCOS?

Reduce inflammation

Studies have suggested chronic low-grade inflammation is a key contributor in worsening symptoms of PCOS. Since inflammation directly stimulates excess ovarian androgen production, it is critical to reduce inflammation to manage many underlying symptoms of PCOS. Fortunately, many antioxidant compounds have impressive anti-inflammatory effects. For example, flavonoids can react with catalytic metal ions to render free radicals inactive.

Balance reproductive hormones for PCOS

The high levels of androgens commonly found in PCOS can lead to acne, hirsutism, irregular periods, and infertility. Evidence suggests that oxidative stress stimulates the androgen-producing ovarian steroidogenic enzymes and may play a role in androgen hypersecretion in women with PCOS.

Improve insulin sensitivity/regulation

Insulin resistance affects the majority of women with PCOS. Higher insulin levels stimulate more androgen production and cause more oxidative stress, resulting in inflammation. The good news is that antioxidant intake has been shown to improve insulin sensitivity. A study suggests diets high in natural antioxidants may help increase insulin sensitivity. This correlates with the results of a 2018 study showing that people with insulin resistance tend to have lower antioxidant levels, especially glutathione. Powerful antioxidant glutathione can be found in tomatoes, and it can neutralize a wide range of free radicals, boost recycling of the other antioxidants such as vitamins C and E, and reduce insulin resistance. Similarly, the catechins, antioxidants present in green tea have been shown to reduce the effects of insulin resistance by the absorption of carbohydrates.  


Higher levels of stress, depression and anxiety are common in PCOS. This can contribute to increased cortisol, which leads to more insulin resistance and inflammation. And this worsens symptoms of PCOS. Eating a healthy diet that is rich in antioxidants can help protect against the inflammation and increased insulin resistance caused by stress. Of course, your best bet is to find ways to manage stress!

Can’t you just take an oxidative supplement?

 According to the National Institutes of Health (NIH), high doses of antioxidant supplements can actually be harmful as they can worsen certain diseases and increase overall mortality. It’s also possible antioxidant supplements may interact with some medicines. And some may be contraindicated in pregnancy. So generally speaking, your best bet is to eat a diet containing plenty of antioxidant-rich plant foods. And the food tastes better than supplements! There are times when your body may need higher doses of antioxidants than what you could obtain from food. Follow the advice of your health care practitioner for supplementation. 


Bottom line

Start thinking more about what you can add to your diet vs what you should avoid. These antioxidant rich spices and herbs are the perfect way to add flavor to your diet … with an added nutritional punch!
