How to Support Thyroid Health Naturally (Simple, Practical Steps)

I’m back again with more talk on the thyroid, but this time it’s all about the practical side and what you can actually do to support thyroid health naturally, and improve thyroid function in women in a simple, practical way.

Before we go any further, I would really recommend reading Part 1 of this series, where I break down just how important this small gland is and the huge influence it has on the entire body, including the early signs of thyroid problems in women.

When it comes to supporting the thyroid, it really comes down to balance. It can feel overwhelming at first, especially as it’s not something many of us are familiar with. So when we suddenly start thinking about supporting it, it can feel like a big shift. But in reality, it doesn’t need to be complicated at all.

Most of the changes are simple, easy to implement, and often things you’re already doing, just with a bit more intention. And the best part is, when you support your thyroid health consistently, the impact on your energy and day to day wellbeing can be huge.

The Key Nutrients your Thyroid Relies on

The thyroid relies on a number of key nutrients to produce and activate its hormones, and once these are in place, the thyroid tends to function much more smoothly and efficiently.

• Iron: is one that’s often overlooked. It’s essential for thyroid hormone production, and low levels can directly impact how well the thyroid is functioning. This is something I see quite often in clinic, particularly in women, so gentle support can make a real difference here.
  
  Our Easy Iron Complex is one option I often use, especially as it includes vitamin C to support absorption.
  
  
• Iodine: is one of the most important nutrients, as it’s directly involved in producing thyroid hormones. Without enough iodine, the body simply can’t make T3 and T4 effectively.
  
  That said, more isn’t always better here, especially if there’s an autoimmune component, so it’s something that needs a bit of care and context before jumping into supplementation.
  
  
• Selenium: works alongside iodine, helping to convert T4 into the more active T3 form, while also protecting the thyroid from oxidative stress. This is particularly important, as the thyroid is very sensitive to inflammation.
  
  With soil depletion meaning we’re often getting less selenium from food, a good quality selenium complex can be a simple way to bridge that gap.
  
  
• Zinc: also supports this conversion process, helping the body activate thyroid hormones properly, while also playing a role in immune balance.
  
  It’s also very supportive of gut health, which is closely linked to thyroid function. Similar to selenium, intake from food isn’t always great, so this is another area where supplements can be helpful. Our Zinc Complex is the form I advise, as it contains zinc bisglycinate as it’s a safe and highly absorbable form of zinc. 

Alongside these, nutrients like Magnesium, Vitamin D, B Vitamins and Omega 3 can help support the wider environment your thyroid relies on, including energy production, immune function, and inflammation balance.

The goal here isn’t to overload the body with supplements, but to make sure it has the right building blocks to do its job properly, and that’s often through natural supplements to help support thyroid function where needed.

What to eat to support your thyroid

Food is one of the easiest and most effective ways to support the thyroid, and It’s often where I start with clients in clinic. It doesn’t need to be complicated or restrictive, just a few consistent additions can make a big difference.

• 2 Brazil nuts a day (sometimes 3 depending on size) can provide your daily selenium needs. Selenium is crucial for thyroid function, and due to soil depletion, many of us aren’t getting enough through our diet anymore. This is one of the simplest and most effective changes you can make.

• 1 tablespoon of pumpkin seeds is a great way to increase zinc intake, which is also key for thyroid hormone activation. I usually recommend grinding them, as they’re quite difficult to break down otherwise. You can easily add them to yoghurt, salads or meals.

• Eggs, meat and fish are important for both protein and tyrosine, an amino acid that acts as a building block for thyroid hormones. Without enough tyrosine, the body doesn’t have what it needs to produce these hormones effectively.

• Seaweed or nori sheets are a great natural source of iodine. I wouldn’t recommend jumping straight into iodine supplementation without guidance, but adding small amounts through food can be a really supportive and safe starting point.

• And finally, fibre is incredibly important. There is a strong connection between the gut and the thyroid, and fibre helps to support digestion, gut health, and the elimination of hormones and toxins. Without good gut function, we’re not absorbing or utilising nutrients properly, which directly impacts thyroid health - aim for 30g daily and 1-2 x scoops of our Intense Greens Super Shake is an ideal source of nutritious fibre.

Alongside this, keeping meals balanced with protein, fats and carbohydrates helps to stabilise blood sugar, which plays a big role in supporting energy and reducing stress on the thyroid.

Simple lifestyle shifts that make a big difference

The thyroid thrives on balance, so when looking at natural ways to support thyroid, lifestyle plays a huge role in creating that balance.

• Stress is one of the biggest factors. When cortisol (your stress hormone) is elevated for long periods of time, it can interfere with thyroid hormone production and conversion therefore impacting thyroid function. Supporting your nervous system, slowing things down, and creating moments of calm can make a real difference here.

• Sleep is another key piece. This is where the body repairs, restores, and balances hormones. Without good sleep, the body simply can’t function optimally, and this includes the thyroid. Aiming for 7–9 hours of quality sleep can have a huge impact.

• Gut health is also closely linked. If digestion isn’t working well, then nutrients aren’t being absorbed properly, which means the thyroid doesn’t have what it needs to function. Supporting gut health through fibre, balanced meals, and in some cases probiotics like Microflora Complex and YourGut Restore, can be really helpful.

Bringing it all together

The thyroid is a sensitive gland, but it’s also incredibly responsive when you support it in the right way. What’s important to remember is that this isn’t about one single fix. It’s about layering small, consistent changes over time, through food, lifestyle, and where needed, supplementation.

I always recommend testing your thyroid if you notice some of the common symptoms, just to understand where you’re at. Sometimes levels may be slightly out of balance, and often this can be supported early on before things progress further. Of course, in some cases medication is needed, but in many situations, there is a lot you can do to support your body before it gets to that point.

If you’d like more personalised support, please do get in touch. And if you’re looking for a simple way to bring some of these nutrients together, then take a look out our Thyroid Complex which contains some of the key nutrients we’ve talked about.

And as always, if you have any questions, I’m always here to help.
