In this age when the importance of human and public health is increasing, inactivity, which is seen as one of the most important problems, and the increase in obesity rates threaten public health. Therefore, the importance of physical activity and nutrition is increasing and new researches are being conducted in this field. The aim of this study is to analyse the relationship between physical health perception and attitude towards the usage of food supplements. Relational survey method was used in this study designed to determine this relationship between variables. 287 academic staff (85= female, 202= male) participated in the study. The physical health statements of the PROMIS global health scale and the scale adapted to the use of food supplements after a literature review were used. As a result, significant relationships were determined between attitude towards the use of food supplements and physical health perception. It was determined that academicians generally considered themselves healthy and were open-minded about the use of food supplements (F=8.150 p=0.000), physical health perception differed according to their field of study (F=4.912; p=0.002), and those who exercised regularly had a higher physical health perception (F=8,339; p>0.05). The study revealed important results in terms of guiding individual, public health and government policies. It is recommended for new researchers to examine the concepts related to rest, sleep behaviours and nutritional knowledge.
