Functional Testing

Normal isn't Optimal.
Why "Everything looks normal"is often just the beginning of the story.

Most women and couples arrive at clinic having already done the right things. They've seen their GP, had their bloods checked, and been reassured that everything looks fine.​ But "normal" isn't the same as optimal. When it comes to fertility, thyroid function and hormonal health, that gap matters enormously.​​

The missing piece is often closer than you'd think. Thyroid function that sits within range but isn't performing optimally. Hormone patterns that tell a different story under deeper investigation. A thyroid-fertility connection that hasn't yet been considered. These aren't rare findings, they're what Nicole uncovers, time and again, in women and couples who've been told there's nothing wrong.​​ 

 

Nicole Peasnell is a Brisbane-based Naturopath with a clinical interest in fertility, thyroid and hormone health. Nicole became a Naturopath after navigating her own health journey with Hashimoto's Thyroiditis and reproductive health challenges. Experiencing first-hand how personalised naturopathic care can make a difference had led her to 20+ years of working with clients, using Nutrition and Naturopathy.

​

Working with women and couples across Australia, Nicole uses comprehensive functional testing and an evidence-based naturopathic approach to explore what standard testing doesn't always reveal.

Who we help support

We have a special interest in supporting a natural approach to fertility, reproductive health, hormonal health and thyroid concerns for women and couples.

Fertility & Preconception

TTC, unexplained infertility, IVF prep, recurrent pregnancy loss, thyroid-fertility link, preconception care, male factor fertility

Thyroid health

Hashimoto's thyroiditis, hypothyroid, hyperthyroid, Graves', subclinical thyroid, thyroid-fertility connection

Hormone health

PCOS, endometriosis, irregular cycles, PMS, perimenopause and menopause

The foundations that support everything else

Optimal thyroid function, healthy fertility, and balanced hormones all rely on a well-functioning gut and a clear picture of what your body is actually doing. These two areas sit at the heart of our root-cause approach.

Digestive health

Digestive health is an important foundation that drives Fertility, Thyroid, Autoimmunity and Hormonal health so is considered as part of our foundational care.

Functional Testing

Functional testing helps take the guesswork out of your health. We use comprehensive panels to uncover the missing links rather than simply manage the symptoms.

Every journey starts somewhere. Book an appointment or free strategy call and explore where yours begins.

The Thyroid-Fertility Connection

Your thyroid and your fertility are more connected than you think

Your thyroid does far more than drive your energy and metabolism. It is highly involved in almost every stage of reproduction, from follicle development and ovulation through to embryo implantation and the early weeks of pregnancy.

 

The thyroid and reproductive hormones are also more closely related than most people realise. When thyroid function is not optimal, the flow on effects on hormonal communication can be far-reaching, potentially affecting ovarian signalling, follicle maturation, and ovulation itself. This influence does not stop there. Thyroid hormones play a role that extends well beyond ovulation, continuing through implantation and into pregnancy.

 

The hidden role of thyroid antibodies in fertility

For women with Hashimoto's thyroiditis, the picture is even more nuanced. Early animal research has begun exploring how Hashimoto's may affect endometrial receptivity, even when thyroid hormone levels appear within the normal range. This emerging area of research is prompting growing interest in understanding how thyroid autoimmunity may relate to implantation, and is one Nicole follows closely in her work with fertility clients.


Why a standard thyroid test may not be enough

Many women are surprised to learn that a standard thyroid check typically measures TSH alone. My approach to fertility naturopathy often involves looking more comprehensively at thyroid function, considering additional markers such as Free T4, Free T3, Thyroid Antibodies, Thyroid receptor antibodies and Reverse T3, alongside key vitamins and minerals for thyroid function, to build a broader picture of what may be going on.
