About me

Hi, I’m Elena, a data-driven Functional Nutritionist. I’m focused on taking your health to the next level through personalised nutrition, functional testing, supplementation & lifestyle programmes.

In my practice – Gut Philosophy - I use genetic and functional testing, wearable data devices and professional supplementation range to optimise your health and monitor your progress .

The examples of functional tests I'm offering include functional blood test, Organic Acid Test, comprehensive hormonal test (e.g. DUTCH), comprehensive stool testing (including gut microbiome), heavy metals & organic toxins testing. 

I work with a wide range of health concerns, all of which were shown to have a strong link to the gut health:

  • Gut related symptoms (bloating, irregular bowel movements)
  • Food allergies and sensitivities
  • Skin issues
  • Weight management
  • Metabolic imbalances
  • Thyroid related concerns 
  • Female hormonal imbalances 
  • Autoimmune conditions
  • Mental health and mood disorders

If you have a health condition, specific goal or simply want to improve your overall nutrition, I’m offering a complimentary 15 min discovery call. You’ll have an opportunity to discover how I work and discuss your health concerns.

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.
