Medigenes Ltd offers nutrigenomics consulting — in person in London and East Sussex, online anywhere. It is built around three goals: managing weight, improving physical and mental performance, and supporting healthy ageing — clearly and honestly, without overstating what a genetic result can tell you.
Consumer genetic tests — 23andMe, AncestryDNA, MyHeritage, Nebula Genomics and others — hand back a report most people read once and file away. The raw data usually holds far more than that report shows. We turn what you already have into practical, personalised nutrition and supplement guidance, in person in London and East Sussex, or online wherever you are.
Send your existing raw data export or report. No need to retest.
In person in London and East Sussex, or by video call, wherever you're based.
Practical dietary direction shaped by what your genetics actually add — not by generic categories.
A tailored view of which supplements may genuinely help, and which are unlikely to make a difference for you.
A sit-down consultation to go through your results together, ask questions as they come up, and leave with a concrete plan.
The same consultation by video call, wherever you're based — nothing about the service changes, only how you attend it.
Practical, sustainable strategies for managing weight, informed by your genetics where it genuinely adds insight.
Nutrition support aimed at energy, recovery and cognitive performance, grounded in evidence rather than trends.
A longer-term approach to nutrition designed to support how you age, not just how you look or perform today.
A genetic result does not determine one correct diet. Some findings may add useful context; many will not change practical advice at all. The service is designed to make that distinction clear, rather than to sell a test.
A structured, genetics-informed approach to sustainable weight management — built around your goals, habits and practical constraints.
Nutrition strategies to support physical and mental performance — energy, recovery and focus — informed by genetics where it adds real insight.
A longer-term nutrition plan designed around healthy ageing, with genetic information used as context rather than a verdict.
Dr David de Lorenzo has spent twenty years working in nutrigenomics — the overlap between genetics and nutrition — across research, teaching and industry.
That has included research and teaching in academic settings, designing nutrigenomics tests, and collaborating with companies working in the field, among them DNAfit and the Nutrigenomics Institute.
It's also why this service is built the way it is: twenty years in this field is long enough to know what genetic data can genuinely add to a nutrition plan, and where it adds nothing at all.
Omega-3. Your FADS1 and FADS2 variants decide whether the flax and walnuts in your diet are enough, or whether you need preformed EPA and DHA. We measure your Omega-3 Index rather than guess, aim for around 8%, and get there with two or three portions of oily fish a week — or about 500 mg a day of algae oil if you don't eat fish.
Caffeine. Your CYP1A2 variant sets your personal ceiling and cut-off time: roughly 3 mg per kg of bodyweight an hour before hard training, and last cup by early afternoon if you clear it slowly, so it isn't still working at bedtime — sleep being the strongest recovery lever you have.
Vitamin A. BCO1 governs how well you convert the beta-carotene in carrots and sweet potato into usable vitamin A. If you convert poorly, you get less than the label implies, and some should come from preformed sources — eggs, dairy, oily fish — rather than from plants alone.
Carbohydrate quality and weight. If you carry the common TCF7L2 variant, a Mediterranean pattern does more for you than it does for most people: in the PREDIMED trial it blunted the variant's effect on cardiovascular outcomes. That turns olive oil, pulses, nuts and whole grains from generic healthy-eating advice into the highest-yield change you can make — and it is the same lever that does the most for weight and blood sugar.
Beetroot and blood pressure. Variants in NOS3 affect how well your body makes nitric oxide through its usual enzyme route — and nitric oxide is what relaxes blood vessels, supports blood pressure and improves oxygen efficiency during exercise. A second route bypasses that enzyme entirely: dietary nitrate, from beetroot, rocket and spinach, converted by bacteria in your mouth. If your genetics point to the first route being less efficient, the second becomes worth building into your week — roughly 250–500 ml of beetroot juice, two to three hours before hard efforts. And skip the antibacterial mouthwash: it kills the oral bacteria that do the conversion, and cancels most of the benefit.
