Supplements for PCOS & Hypo thyroidism

I am often asked what supplements I take as someone who suffers with PCOS and Under-Active Thyroid.

I am discovering new things all the time and one thing I have learned is that education is never over when it comes to nutrition.

There is a number of supplements that can help Thyroid but can also interfere with Levothyroxine medication, so it is important to be aware of any supplements recommending support for Thyroid if you are taking medication.

Disclaimer: I am not a medical professional so cannot recommend nor prescribe any form of medication or supplement for a medical condition however, I can suggest you do some research on the supplements I take to see if they could also help you.



Otherwise know as vitamin B8. It's a type of sugar that helps your body process insulin and has studies showing positive effects for those with PCOS restoring ovulation and normalising hormone levels.


Is an essential component of various enzymes and proteins, called selenoproteins. Several studies have shown that supplementing with selenium reduces the severity of hypothyroidism symptoms.

Omega 3,6,9

Types of unsaturated fatty acids, fats that are good for you. These are great for heart health, inflammation, and mental health. Studies have also found that omega-3's can decrease inflammation that compromises thyroid function.


Important in making red blood cells, which carry oxygen around the body. The body is dependent upon iron to convert thyroxine. Low iron levels can impede the thyroid function and cause fatigue.


A vitamin involved in metabolism. Studies suggest that a deficiency could be linked to increased fat accumulation and obesity. It is also a vitamin that helps convert food to glucose which gives you energy and also needed for the production of serotonin which helps you to feel happy.



  • Please remember it is always important to take your Levothyroxine alone on an empty stomach, ideally 1 hour pre food (some recommendations for this may vary)

  • Another important thing to remember is that you can get all of these supplements from whole food sources, however the standard diet does tend to lack many vital vitamins and minerals

  • Supplementing alone will unlikely improve your symptoms. It is important to remember that a nutrient dense diet along side exercise is the primary importance
