The F.E.B.S Protocol (Functional Epigenetic & Biochemical Screen) blood test is a comprehensive approach developed by The Nadura Clinic to address biochemical disorders such as anxiety and depression. The program, which has been evolving for over a decade, offers a personalised and targeted nutrient therapy approach based on the Walsh Research Bloods Profile developed by Dr William Walsh in Chicago. 

At The Nadura Clinic we utilise a specialised laboratory analysis including Folate, Vitamin B12, Zinc, Vitamin D, Copper, Caeruloplasmin, Homocysteine, Histamine and Thyroid Stimulating Hormone. This gives us a great insight into the client’s methylation status and free copper levels. 

Based on laboratory results we create targeted protocols focusing on each client’s unique biochemical individuality and their specific nutrient requirements. The F.E.B.S protocol takes into account various factors that affect the production and expression of neurotransmitters, including our genes but more importantly our epigenetics; gastrointestinal health, nutrient intake, stress management, mold exposure, antioxidant status, chemical exposure to name a few.

The program is carried out by a team of highly qualified professionals, including nutritionists, a registered mental health nurse, a biochemical and advanced nutrient therapy specialist encompassing a comprehensive professional referral system with some of our medical collaborators including integrative psychiatrists, trauma therapists, counsellors, CBT therapists & psychotherapists.

The advances in science over the past number of decades has been astonishing and we now know that not only do our diets and lifestyle habits change how our genes express – a study known as epigenetics, but also whether in fact deficiencies, and in some cases nutrient overloads can also have a profound impact on our mental health status. 

The most underappreciated fact is that our brain chemicals including serotonin and dopamine for example are produced from protein in our daily diet, but also require certain vitamins and minerals known as cofactors for adequate production. At The Nadura Clinic, we have also seen in combination with our advanced nutrient therapy, the immense importance and benefit to ensuring the health of our gastrointestinal tract as research continues to mount in the area of our gut to brain axis being implicated in mood disorders.
