• Deborah has presented at our academic programme. Her knowledge of the evidence base combined with years of clinical experience was compelling. It stimulated a great deal of interest and discussion and we are inviting her back.

Thinking Nutrition delivers expertise in nutrition intervention for mental health and emotional well-being. Deborah Colson, founder, is available for nutrition consultations, corporate projects, lectures and other speaking or writing engagements.

  • I consulted Deborah for my son (then aged 11) who was experiencing learning and behavioural difficulties. Following some tests, we followed an exclusion diet and supplement programme for 6 months. We were also given dietary advice on healthy eating and, as a result, the whole family has changed their eating patterns. Five years on, our son has voluntarily stayed on for higher education – something we could never have imagined back then.
