Why Your Gut Health Deserves Attention

Your gut is home to trillions of microorganisms that play a vital role in digestion, metabolism, immune function, and even mental well-being. While many of these microbes support good health, an overgrowth of harmful bacteria can disrupt this delicate balance—leading to bloating, food intolerances, inflammation, constipation, diarrhoea, weight fluctuations, and long-term health risks.

Factors like diet, environment, genetics, and lifestyle all influence the diversity of your gut microbiome. A diverse microbial community is considered a hallmark of a healthy gut, while reduced diversity or the absence of certain beneficial species has been linked to issues such as obesity, autoimmune conditions, and chronic inflammation.

This test is ideal for:

  • Anyone experiencing bloating, irregular digestion or food sensitivities.
  • Individuals looking to optimise gut health and overall wellness.
  • Those with a history of digestive issues, IBS, or inflammatory conditions.
  • People interested in personalised nutrition and microbiome insights.

what do we analyse

Scope of Analysis: Gut Health Testing

Core Microbiome Composition

Top Bacterial Phyla: Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria, Verrucomicrobia

Balance Overview: Compares your microbiome to reference ranges to determine increases or decreases in key groups.

Microbiome Health Metrics

Richness: Number of different species in your gut — higher richness indicates a more resilient microbiome.

Diversity: A diverse range of bacteria supports better digestion, immune function, and metabolic stability.

Evenness: Indicates whether bacterial populations are balanced or dominated by certain strains.

Firmicutes/Bacteroidetes Ratio: A common marker for metabolic health; linked to weight regulation and digestion.

Functional Bacteria Analysis

Butyrate-Producing Bacteria: These support gut lining integrity, reduce inflammation, and may protect against colon cancer.
Includes Faecalibacterium prausnitzii, Roseburia, Eubacterium rectale, etc.

Probiotic & Beneficial Bacteria

Evaluation of key probiotic strains such as Lactobacillus (e.g. acidophilus, rhamnosus) and Bifidobacterium (e.g. longum, bifidum), with reporting on their roles in digestion, immune support, and gut-brain axis functions related to mental well-being.

Pathogenic & Opportunistic Microorganisms

Evaluation of pathogenic and opportunistic microorganisms, including:

Bacteria such as Clostridium difficile, Helicobacter pylori, Salmonella, Shigella, toxic strains of E. coli, and Campylobacter jejuni
Fungi such as Candida albicans
Protozoa including Giardia lamblia, Entamoeba histolytica, and Cryptosporidium spp.
Viruses such as Norovirus and Rotavirus with reporting on their potential to disrupt gut health or contribute to infection and inflammation.

Microbiome-Disease Associations

Analysis of correlations between gut microbiota composition and a spectrum of clinically relevant conditions, including:
Gastrointestinal disorders such as IBS, IBD, Crohn’s disease, and Ulcerative Colitis
Metabolic syndromes including obesity, type 1 and 2 diabetes, and nonalcoholic fatty liver disease (NAFLD).
Autoimmune conditions such as Hashimoto’s thyroiditis and systemic lupus erythematosus.
Cardiovascular risk factors including hypercholesterolemia and hypertension.
Neuropsychiatric and neurodegenerative disorders including anxiety, depression, and Alzheimer’s disease.
Dietary intolerances such as gluten and lactose sensitivity.

with detailed reporting on microbial signatures associated with increased or decreased risk profiles.

Personalised Recommendations

Includes tailored advice for:
-Diet: Fibre-rich foods, probiotics, prebiotics.
-Lifestyle: Sleep, stress management, physical activity.
-Supplements: Where relevant, based on microbial deficiencies​.
