About nutritional therapy

Nutritional Therapy is for anyone who wants to improve his or her health. You may have a specific health problem or you may want to know how to eat to prevent health problems in the future. You may simply want to lose some weight or have more energy. With the help of a nutritional therapist you have the power to make a very profound change to your health.

There is an ever increasing amount of health information bombarding us from many different sources which whilst useful in some respects, can also lead to considerable confusion. Would you try to fix your own car? No, most people would take it to a mechanic. Many people have found that the most effective approach is to receive an individually tailored wellness plan to fit their particular health picture.

How does nutritional therapy work?

Nutritional Therapy is about much more than healthy eating and taking a multivitamin supplement. It is a healthcare system that explores ways of balancing a person's nutrition in order to achieve optimal wellness. Whilst a nutrient dense, optimally balanced diet is the basis, there are many other factors to consider.

Nutritional deficiencies

Lack of vitamins, minerals and amino acids can be due to straightforward insufficient intake through the diet. They can also often be the result of poor digestion and absorption. In addition, it is not uncommon for metabolic imbalances to occur, which are individual for the particular person and which cause functional deficiencies. These type of deficiencies mean that despite adequate intake of a nutrient, a body function that depends on that nutrient is not working properly, because the body cannot metabolise the nutrient. A good example is folic acid. Around 30 percent of women have a functional folic acid deficiency, with major negative consequences for the brain, immune and hormonal systems.


Hormone, blood sugar and essential fatty acid imbalances are often too subtle to show up in conventional tests but can have a significant effect on health and are easily corrected.

Digestive problems

Poor digestion and absorption can lead to deficiencies of vitamins, mineral and other nutrients. It also can result in bloating, gas and bowel problems. Dysbiosis (imbalance of gut bacteria) is often a major factor affecting digestion.

Allergies and intolerances

These may be to foods or to environmental allergens. When allergies or sensitivities are present, they make the absorption of nutrients less efficient. It is a case of which comes first, as poor digestion in the first place, makes food intolerances more likely.

Toxic overload

The liver and the bowel are two major organs of detoxification. They ensure that the multitude of toxins that we are exposed to daily, are metabolised and excreted from the body. Nutritional support and gentle herbal cleansing regimes may be suggested to improve liver and bowel function.


Often great results can be obtained without testing. However sometimes this is useful if more information is needed. There is a range of innovative functional medicine tests that help to pinpoint nutritional and biochemical imbalances. These tests may involve urine, blood, saliva or stool. Examples of the most commonly used tests are Live Blood Microscopy, FACT (food intolerance) Adrenal Stress Index, thyroid hormones, Osteoporosis Risk Assessment, Stool Analysis (digestive function, fungal overgrowth, parasitology & bacteriology), and Metabolic Analysis. These tests, if required, are at additional cost to the consultation.


Some people ask me, "If I follow a healthy diet why do I need to take supplements?" Or "Won’t my multivitamin from the local health food shop be enough?"

It is possible to feel well through diet alone. However, most people who do not feel in 100 percent good health will benefit from some degree of supplementation. In addition to the points mentioned above, there are many individual factors that will dramatically increase your needs for certain vitamins. For example stress, intensive exercise, alcohol consumption, infections, heavy menstruation, diarrhoea or prolonged use of certain medications. Each of these factors means that you use up larger than usual amounts of specific nutrients.

Add to this intensive farming practices and environmental influences which have led to a declining nutrient content in our fruit and vegetables and you get the picture of how our food has changed. If you do not feel completely well, taking a basic multivitamin is unlikely to be sufficient to rebalance your nutrient “bank account”. Neither is making a random selection of supplements based on the latest newspaper or magazine article. A nutritional therapist has the expertise to pinpoint the supplements you need and which will really work, based on your clinical symptoms and/or biochemical tests.

Here is a sample of genuine, unsolicited quotes from clients:

“I am following meticulously the diet and taking the supplements and it works wonderfully. I don’t have any gas or bloating any more”.

“Just wanted to let you know that I am feeling great again! My stomach has totally settled down. I have been able to eat meat and digest it without a problem. Whereas before I would have said my energy levels were about 80%, I would say they are now 90-95%.”

"I can't thank you enough, I feel so much better."

“The diet is going great. I lost 8 kilos without much trying and the programme really suits me.”

“The supplements have literally changed my life (well made a big difference anyway!).”

“Many thanks for the session last week – it was really useful and informative – have been raving about your insights and advice to everyone since!

“I am delighted to let you know that I feel so much better since I have been taking the supplements. I have been really happy, sleeping better and had so much more energy than normal. So thankyou for your spot-on “diagnosis” and advice.

"It's changed my life!"

"So many, many thanks for your most intelligent and kind help during my pregnancy. You were my best 'doctor' ever."

"The change of diet you recommended seems to have got rid of most of my hayfever and dust allergy. I no longer take anti-histamine tablets."

"I feel like a new person."

"I can't recommend your services highly enough. You're magic!"

"This is the best money I've spent."

“I’ve been meaning to say a huge thankyou for months. Your advice was brilliant. I achieved my transformation in just 12 weeks and knowing what and when to eat was the difference. I was 209lbs when I started and finished at 185lbs.”

“I’ve been feeling so much better since following your plan. I haven’t taken acid reducing tablets in 6 months”.

“We are delighted with our pregnancy and we are very grateful for all the help and advice you have given”.

"Thankyou very much for helping us get pregnant. I am sure that it is not entirely coincidental that after 3 months of taking supplements and changing our diet, I became pregnant. Good luck with your practice and I will continue with the trend of recommending you to others in need."

"This is fabulous news that I am pregnant and we are over the moon. I am in no doubt that the situation is due in large part to your advice and expertise which has made me feel better, thankyou".

"Thankyou so much for a wonderful session - I felt like I gained some real insights and you asked some very helpful questions".
