My nutrition consultancy practice is based on the orthomolecular model, which varies somewhat from the approach of mainstream dietetics. Rather than monitoring macro nutrient ratios and caloric balance, I address the micronutrients (vitamins and minerals) in your diet. So no meal plans or calorie counting!

The orthomolecular model posits that an optimally healthy body requires a well-balanced micronutrient environment, and that certain diseases or ailments are a result of deficiencies in essential nutrients. It involves attempts to correct these imbalances and deficiencies by use of food and supplements such as vitamins, minerals, amino acids, trace elements and fatty acids. All therapies are based on your individual biochemistry, so you are guaranteed a personalized approach. Orthomolecular therapy is a complementary system and works alongside regular medical interventions, rather than replacing them.



Are you ready to make meaningful changes in your life and habits but don’t know where to start or feel that there is an insurmountable mountain standing in your way? Let’s make an appointment and get you on track to living the best life you can while working towards your goals.

Coaching is not about giving you answers and solutions, but rather guiding you to finding them yourself. True, long term progress can only be achieved with honest introspection and confronting your own inadequacies, thereby growing as a person. Life will never get easier, but you will become stronger!
