Functional testing

Get Clarity. Get Answers. Get energy.

When you’re exhausted, bloated, anxious, or hormonally all over the place — but your GP tests keep coming back “normal” — it’s frustrating. You know something isn’t right… you just can’t see what.

Functional testing goes deeper.
Instead of asking “Is there disease?”, it asks:
“Where is your body struggling to function optimally?”

These advanced tests uncover hidden imbalances in your hormones, gut health, stress response, nutrient status, thyroid function and more — giving us the insights needed to create a personalised, effective plan for your health.

Why Functional Testing?

Functional testing helps you:

  • Stop guessing what’s going on

  • Understand the root causes of fatigue, anxiety, bloating, hormone issues and stubborn weight

  • See how your body is really functioning, not just whether it’s within disease ranges

  • Personalise your nutrition, supplementation and lifestyle strategy

  • Make faster progress with fewer wrong turns

It is not about finding diagnoses — it’s about finding answers.

Testing is optional but incredibly valuable when:
✨ Symptoms have been ongoing
✨ You’ve “tried everything”
✨ You want precise, efficient progress
✨ You suspect hormones or gut health are involved
✨ You feel ignored or dismissed by previous tests
