About me

I started Renua Nutrition to help individuals get to the root cause of their ongoing health issues which are often overlooked by our healthcare system. It may be ongoing struggles with gut health, food intolerances, unexplained fatigue, breakouts, hormonal symptoms, weight-loss, healthy eating or other difficult to diagnose concerns.

What To Expect In Your First Session:

I start with an initial consultation, during which time we will discuss your health history and the symptoms you are experiencing. I will also analyse your current diet and lifestyle. From here I create a personalised nutrition and lifestyle plan which meets your health goals. Additional functional diagnostic testing and supplemental support may be recommended based on your symptoms.

Types of functional testing available (but not limited to):

Gut Microbiome
Food Intolerance
Thyroid Panels
SIBO Breath Test
Adrenal Stress Tests
Comprehensive hormone panels (DUTCH test)
Organic Acid Testing (OAT)
Cyrex Immunology Testing
Finger Prick Tests for a range of health markers
Biological age 

Genetic Testing

 Nutrigenetics is the practice of matching your nutritional needs to your unique genetic profile. Each of us has variations in our genetic code that can affect us on a nutritional and performance level. This could range from impaired detoxification to sub-optimal recovery from workouts. By personalising your micro-nutrient intake will enable you to optimise your health and perform at your best.

We offer genetic testing for:

Skin health
Mental Health
Weight Loss

Nutrition Programmes

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.

Our programme range from 4 weeks to 16 weeks and I will advise on the most suitable programme to meet your health goals.

 For further information on programmes please visit my website: https://www.renuanutrition.com/services

I always recommend you take advantage of our complimentary health assessment phone call. This is a no obligations call. We simply discuss your health goals and symptoms.  If appropriate to work together I will suggest a next step for you.

"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

"Katherine is extremely knowledgable and has made a huge difference in how I've managed problems with my digestion and my energy levels. She's very patient, generous with her time and I recommend her without reservation." - Jane, 63

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.
