Nutrigenomics in Practice

Understanding how your genes influence your health

What Is Nutrigenomics?

Nutrigenomics is the study of how your genes interact with the food you eat, the nutrients you absorb, and the environment you live in. It helps us understand why two people can follow the same diet yet experience very different health outcomes.

At The Autoimmune Clinic, nutrigenomics is used as a tool to personalise your care. It allows us to move away from a one-size-fits-all approach and instead tailor nutrition, supplementation, and lifestyle strategies to your unique

Your DNA contains variations known as single nucleotide polymorphisms (SNPs). These are small genetic differences that can influence how your body functions.

These variations may affect:

How you detoxify toxins and hormones
How your immune system responds
Your ability to manage inflammation
How you produce energy at a cellular level
How you process nutrients such as B vitamins, vitamin D, or omega-3 fats

Nutrigenomics looks at these patterns to identify where your body may need additional support.

WHY DOES THIS MATTER IN AUTOIMMUNE AND CHRONIC ILLNESS?

In complex conditions such as autoimmunity, chronic fatigue, MCAS, or mould-related illness, the body is often under significant stress. Nutrigenomics can help identify underlying vulnerabilities that may be contributing to this.

For example:

Impaired detoxification pathways may reduce your ability to clear toxins, mould exposure, or medications
Variations in methylation genes may affect neurotransmitter balance, hormone metabolism, and immune regulation
Differences in antioxidant capacity may increase susceptibility to oxidative stress and inflammation
Histamine-related genes may influence your sensitivity to foods and environmental triggers

Understanding these patterns allows us to support the body more precisely.

WHAT DOES TESTING INVOLVE?

Nutrigenomic testing is simple and non-invasive. It typically involves a saliva sample or cheek swab, which is then analysed in a laboratory.

The results provide insight into key biological pathways, including:

Detoxification (liver pathways)
Methylation and B vitamin utilisation
Inflammation and immune regulation
Oxidative stress
Hormone metabolism
Nervous system function

It is important to understand that this is not a diagnostic test. Instead, it provides a blueprint of your genetic tendencies.

How we use Nutrigenomics in practice

At The Autoimmune Clinic, we do not treat genes in isolation. Your genetics are considered alongside your symptoms, health history, environment, and other test results.

We use this information to:

Personalise your nutrition plan
Select supplements that your body is more likely to tolerate and benefit from
Avoid interventions that may not suit your genetic profile
Support detoxification and drainage pathways safely
Optimise energy production and mitochondrial function
Reduce inflammation and stabilise immune responses

This is particularly valuable in individuals who are highly sensitive or reactive, where a more targeted and gentle approach is required.

Nutrigenomic testing and interpretation within the clinic is supported by Claire, who is a certified Lifecode GX practitioner.

This ensures that your results are explained with a high level of clinical precision and translated into practical, personalised recommendations.

Is Nutrigenomics for you?

Nutrigenomic testing may be helpful if you:

Have a complex or long-standing health condition
Feel that you react to multiple supplements or foods
Have not responded to standard approaches
Want a more personalised and targeted plan
Are dealing with autoimmune disease, MCAS, chronic fatigue, or environmental illness

If you are interested in exploring nutrigenomics as part of your health journey, we recommend starting with a discovery call or initial consultation.
