The aim of this study was to evaluate the status of consumption and consumer satisfaction of dietary fiber supplements. The survey was conducted using a self-recorded questionnaire developed to meet the purpose of this study. The characteristics of the subjects who have taken dietary fiber supplements in the past are as follows: distributions of socioeconomic variables showed that the highest-ranked group(the group that reported the highest consumption of dietary fiber supplements) was professionals with a college degree or higher degree. In addition, the highest-ranked group were the most healthy, nonsmokers and reported drinking habits of ‘1～2 times/week’. Regarding the health status of those surveyed, digestive disease and constipation were the most common complaints. The majority responded with ‘health concerns’ to the question that asked the reason for their purchase of the dietary fiber supplements. Three major places respondents could find dietary fiber supplements were ‘through the internet’, ‘the market’, ‘the pharmacy’ in descending order. The compositions of dietary fiber products varied. ‘konjac’, ‘cellulose’, ‘psyllium husks’ were the most popular components consumed by the subjects. The average duration of product consumption was less than one month. In terms of satisfaction levels(satisfaction was ranked from 1 to 5), ‘taste’ and ‘type’ scored the highest in satisfaction levels while ‘price’ ranked the lowest. When subjects were asked about self-awareness regarding the physiological efficacy of dietary fiber supplements, the responses were positive in ‘bowel movement’ and ‘weight loss’. Further research is required to improve the quality of dietary fiber supplements in order to assist consumers in selecting the appropriate products.
