Autoimmune thyroid nutrition
Hashimoto's & Thyroid Nutrition Therapy.
On medication — but still not feeling right. There's a reason.
Clinical nutrition therapy for Hashimoto's thyroiditis and hypothyroidism — addressing the autoimmune driver, not just the thyroid hormone numbers.

A personal specialisation
"I have Hashimoto's. I know exactly what you're going through."
I was diagnosed with Hashimoto's thyroiditis myself. I know what it's like to be told your TSH is normal while feeling anything but. I know the frustration of doing everything right — eating well, exercising, sleeping — and still not feeling like yourself.
That experience is what drew me to specialise in autoimmune thyroid nutrition. Every patient I treat with Hashimoto's gets the clinical expertise of a registered dietitian and the understanding of someone who has navigated this condition from the inside.

Does this sound familiar?
"I'm taking my medication. So why do I still feel like this?"
Always cold, always tired.
Even in summer. Even after 8 hours sleep. A fatigue that no amount of rest seems to resolve.
Weight that won't shift despite medication.
Your TSH is "normal" — but the scale disagrees. And your GP doesn't have a clear answer.
Hair coming out in the shower.
More than feels normal. Often connected to zinc and iron deficiencies that standard blood panels miss.
Mood low, thinking foggy.
Not quite depression. Not quite stress. The kind of mental heaviness that nobody seems to connect to thyroid function.
These symptoms don't disappear with a prescription alone. They respond to nutrition.
What makes Hashimoto's different
Hashimoto's is the cause. Hypothyroidism is the result.
In Hashimoto's thyroiditis, the immune system attacks and gradually destroys thyroid gland tissue. Hypothyroidism is what follows — but treating the thyroid hormone numbers alone, without addressing the underlying autoimmune process, is why so many patients remain symptomatic despite medication.
Clinical nutrition for Hashimoto's works on two levels: restoring the nutritional deficiencies that worsen the autoimmune process, and reducing the gut inflammation that drives it. Both are necessary. Neither happens automatically on levothyroxine alone.
The clinical picture
Three numbers worth knowing.
40%
reduction in thyroid antibody levels with targeted selenium supplementation over 3 months.
Peer-reviewed clinical evidence
75.9%
of Hashimoto's patients have lactose intolerance — affecting how well levothyroxine is absorbed.
Peer-reviewed clinical evidence
2×
lower Vitamin D levels in Hashimoto's patients compared to healthy individuals — worsening inflammation.
Peer-reviewed clinical evidence
These aren't incidental findings. They are correctable nutritional factors that directly affect how well your thyroid functions and how you feel.
Two dietary flags specific to Hashimoto's
What the evidence actually says.
Gluten
A gluten-free trial may reduce antibodies.
Gluten has a structural similarity to thyroid tissue — in some patients, this triggers an immune response that elevates anti-TPO and anti-TG antibodies. Coeliac disease is 10x more likely in Hashimoto's patients than in healthy individuals.
It is NOT necessary to go gluten-free unless coeliac disease or gluten sensitivity is confirmed. Your dietitian will assess this with you.
Lactose
Lactose intolerance affects your medication.
75.9% of Hashimoto's patients have lactose intolerance. If you're taking levothyroxine, undiagnosed lactose intolerance reduces how well the drug is absorbed — meaning you may need higher doses than necessary.
A lactose tolerance test is worth discussing with your doctor — especially if your TSH levels are inconsistent despite consistent medication.
The nutrition protocol
A four-pillar approach to Hashimoto's.
01
Gut health
Microbiome & inflammation
Hashimoto's patients show microbiota dysbiosis that drives autoimmune activity. High-fibre foods, omega-3 fats and limiting refined carbohydrates restore the gut environment that keeps antibodies in check.
02
Nutrient restoration
Selenium, zinc, iron, Vitamin D
Each of these nutrients plays a direct role in thyroid hormone production or immune regulation. Deficiencies in any one of them worsen Hashimoto's progression — and targeted supplementation is a crucial part of the protocol.
03
Anti-inflammatory eating
Mediterranean-based food pattern
Lean protein, fatty fish, quality fats, wholegrains and vegetables — the dietary pattern most associated with reduced autoimmune activity. Refined carbohydrates and saturated fats drive the inflammation that worsens Hashimoto's.
04
Personalised plan
Built around your blood work
Your TSH, T3, T4, TPO antibodies, iron, Vitamin D and zinc levels — all reviewed in your Deep Dive. Your meal plan, supplement protocol and dietary adjustments are built around your specific results, not a generic template.
