Gut Microbiome Testing (UK-Wide)

Gut Health with Sarah Flower Nutritionist & Author
Restore your gut.  Reclaim your health

Your gut health plays a critical role in your digestion, immune system, mental wellbeing, hormone balance, and even your metabolism. But many people struggling with bloating, IBS, food reactions, or fatigue are given generic advice or food intolerance tests — without ever looking at the real root cause: the microbiome.

 

As a UK-based functional nutritionist, I work with clients nationwide to test and restore their gut health using personalised stool testing, targeted supplements, dietary changes, and lifestyle support.

What does gut testing reveal?

A comprehensive stool test offers an in-depth look at:

 

  • Microbiome diversity

  • Good vs. bad bacterial levels

  • Inflammation and immune markers (like sIgA)

  • Digestive function (elastase, fat absorption, pH)

  • Yeast and fungal overgrowth (e.g., candida)

  • Pathogenic bacteria and parasites

  • Short-chain fatty acids (SCFAs)

  • Leaky gut indicators (e.g., zonulin)

 

 

I also offer breath tests for SIBO (Small Intestinal Bacterial Overgrowth) and specialist tests for H. pylori, Candida, Coeliac disease, and more.

Not sure which test is right for you?

Many people ask me if they need food intolerance testing — and while it can be helpful, I often find we get far better results by starting with gut repair first.

 

Before spending £300+ on a test that may not give the full picture, I recommend booking a free 15-minute discovery call. I’ll help you understand what’s going on and what test (if any) would help most.

I offer:

 

  • UK-wide gut testing via post

  • Clinical interpretation and explanation of your results

  • Full nutritional therapy support (diet, supplements, lifestyle)

  • Targeted protocols for SIBO, Candida, low stomach acid, and more
