Home study course

This course is non-academic and is to be completed in your own time. You will receive all the textbooks and course documents in the post, and have one year to complete the work and register to take our exam. Home study is aimed at students interested in enhancing their knowledge of the industry, but not necessarily seeking a professional qualification. The fee is £199.

Science Access

This course is for those who wish to be enrolled in the Nutritional Therapy Diploma, but do not have the science prerequisites. We offer three access courses, and students can choose which are most relevant to them; Chemistry, Biology, and Human Anatomy & Physiology.
