Gut and nutrition
Most nutritional problems we find are not exotic. Iron deficiency, vitamin D insufficiency and inadequate protein are common, correctable, and frequently missed because nobody looked. The gut work sits alongside that rather than replacing it.
Programmes in this area
Gut microbiome programme
Assessment and support of gut health, which influences digestion, immune regulation, inflammation, mood and how well nutrients are absorbed. A home stool sample maps the composition of your gut bacteria, and testing can distinguish food intolerance from allergy where symptoms point that way. Management is dietitian-led and food-first, concentrating on fibre diversity, fermented foods and eating patterns, with targeted supplementation only where it is justified. Persistent symptoms such as reflux, bloating or altered bowel habit are assessed properly rather than managed indefinitely with over-the-counter relief.

Correction of the vitamin and mineral deficiencies that quietly affect energy, sleep, mood, immunity and muscle function. The programme measures rather than guesses, covering vitamin D, B12, folate, iron studies, red cell magnesium and omega-3 index, since intracellular and functional markers often tell a different story from standard serum testing. Where genetic testing has been done, it can inform how your body handles particular nutrients. Repletion is then targeted and monitored, with retesting to confirm levels have genuinely corrected rather than assuming they have, since absorption varies considerably between individuals.

Supplement planning built on your measured results rather than general recommendation. Most people take supplements they do not need and miss the ones they do, which is expensive and occasionally counterproductive, since some nutrients interact or become harmful in excess. The programme uses your laboratory results, dietary assessment and, where available, genetic data to build a focused protocol using pharmaceutical-grade formulations. Dosing is specified, interactions with prescribed medication are checked, and levels are retested so the plan can be scaled back once repletion is achieved.

Assessment and correction of iron deficiency, a common and frequently missed cause of fatigue, poor exercise tolerance, hair loss and reduced concentration, particularly in menstruating women and endurance athletes. Full iron studies including ferritin are measured, because haemoglobin alone can look normal while stores are depleted. Treatment is matched to severity and tolerance, using dietary strategy, oral supplementation, or intravenous iron where oral treatment is insufficient or poorly tolerated. Iron overload matters equally, since excess accelerates oxidative damage and is easily missed, so testing always precedes treatment in every case.

Is a microbiome test worth doing?
Not as a first step, and the current evidence does not support it for general wellness. International consensus does not recommend routine microbiome testing, and a 2026 reliability study found consumer providers producing markedly different results from identical samples. Where testing is done it belongs with a clinician interpreting it.
What is actually assessed?
Symptom history, the established tests appropriate to what you describe, and micronutrient status including iron studies, vitamin D and B12. Where symptoms warrant it, onward referral for endoscopic or specialist assessment.
Do I need supplements?
Only where a deficiency or a clear indication is demonstrated. A supplement protocol built on measurement is a different proposition from one built on a questionnaire, and most people need fewer than they are sold.
