mBANT, Gut Health Specialist & Nutritional Therapist, London

About me

I started Renua Nutrition to help individuals get to the root cause of their ongoing health issues. It may be ongoing struggles with bloating, unexplained fatigue, breakouts, hormonal symptoms, weight-loss, healthy eating or other difficult to diagnose concerns. I will start by analysing your symptoms and medical history to get to the tigger of your issues. From here I create a hyper-personalised nutrition and lifestyle plan which meets your health goals. Additional diagnostic testing and supplemental support may be recommended based on your symptoms. The types of functional testing which can be carried out includes:

Gut Microbiome
Food Intolerance
Thyroid Panels
SIBO Breath Test
Adrenal Stress TestsComprehensive hormone panels (DUTCH test)
Organic Acid Testing
Cyrex Immunology Testing

I have honed my knowledge and skills in nutritional therapy through working in a number of Health Optimisation and Functional Medicine clinics in central London. These include: LMS Wellness; BelleCell and Harpal Clinic.

I understand the need to provide constant coaching support for my clients as they often have busy lifestyles and appreciate having someone to be accountable to. Because of this I generally recommend programmes to achieve the best results as it allows time for biochemical and habitual changes.

As a company we are driven by data and understand that every client needs a different level of support. This is why I have created programmes which vary in length and include maintenance support. Experience has taught us that the maintenance phase of a programme is just as important as the initial stages. For further information on programme please visit my website: https://www.renuanutrition.com/services

I always recommend you take advantage of our complimentary diagnostic assessment, during which time will we suggest the most suitable programme for you.


If you wish to have an initial consultation to get started and then move onto  a programme this is also possible.

Consultation Options
Initial Comprehensive Consultation | 75 minutes | £160
Initial Essential Consultation |  45 minutes | £95

All consultations are delivered through an online platform as this gives you the flexibility to attend from anywhere and is the safest option at this time.

For hyper-personalised nutrition plans we offered nutri-genetic testing. This will show you how you metabolise certain vitamins, antioxidants and caffeine. These have a knock-on effect on your energy levels, mental & physical performance and detoxification. Genetic predispositions to lactose and gluten intolerances will also be determined along with sensitivities to fats and carbohydrates.

"I got in touch with Katherine after experiencing some health problems last year and needed to make some changes to both my diet and lifestyle. Wanting to make an informed decision and one that would be sustainable I thought it best to consult a professional. Katherine requested detailed information about my life, eating habits and health issues before issuing her advice and considered all aspects when providing her assessment. Katherine gave practical advice that was easily transferable into my daily routine and provided detailed explanations behind each suggestion - which gave me great confidence in her decision making. Based on my experience in dealing with Katherine, I would thoroughly recommend her services to anyone wishing to make positive changes to their lifestyle." - Kate, 27

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.

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a Nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the Nutritionist to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.

I offer online consultations which can be done in the comfort of your home.
