Melissa Marston, Nutritional Therapist

Online Nutritional Therapy

Nutritional Therapy uses the science of nutrition to support chronic conditions and/or promote optimal health in children and adults. 

I apply the principles of Functional Medicine in my nutritional approach, which means that I will aim to uncover the underlying root cause of your symptoms.

I have a special interest in gut health and gained extensive experience working as part of a team at a gut specialist clinic based in London.

‘Melissa listens, investigates and tests based on sound scientific principles. I would be happy to recommend her to anyone with problems related to their digestive system.’

My specialist areas include:

  • IBS (irritable bowel syndrome)
  • SIBO (small intestine bacterial overgrowth)
  • Candida
  • Ulcerative Colitis
  • Diverticulitis
  • Acid Reflux
  • H. Pylori infection
  • Intestinal parasites
  • Intestinal permeability
  • Histamine Intolerance


“Before coming to see Melissa I was really struggling with stress because my skin was at an all time high!  I had rosacea and I had been trying to do my own treatment but I felt very overwhelmed by all the things I needed to implement. 

Melissa was really helpful and explained what she thought was the underlying cause for my inflamed skin and which foods might be triggers.  We worked on my diet and gut health (low histamine diet and SIBO), and although the skin got really sore just as I implemented the changes, it has now been over a year since I finished working with Melissa and my skin is glowing!

 Sometimes I still get breakouts if I eat the foods that are wrong for me, but it has never been as bad as it was when I came to see Melissa.  I feel so much more confident now.  I love it!”
