Previous studies have quantified the extent of usage, knowledge, and relationship of people's behavior in regard to food supplements--particularly in developed countries such as the United States. Despite the prevalence of supplements use and the issues surrounding its use, there has been little or no study of supplement use in a developing country like the Philippines. This study aimed to explore, qualitatively, the concept, motivations, and expectations of a select group of Filipino elderly relative to their use of commercialized food supplements (CFS). Five faculty extendees from a private university in the Philippines were selected in this phenomenological study. A two-part research instrument consisting of a robotfoto and a face-to-face interview guide with semistructured questions was used. Extended texts were subjected to phenomenological reduction via repertory grid analysis. Conceptual clusters that emerged were subjected to the member checking procedure for purposes of ensuring data trustworthiness. Through constant comparison of the concepts, expectations, and motivations of the respondents of the study relative to their use of CFSs, a clear-cut taxonomy of users was identified: (a) the idealist-experimentalist and (b) the realist-pragmatist. The emerged typologies in this study create a picture that can help healthcare providers understand the dynamics of patient behavior toward CFS use. Implications of the study to health education are also documented in this paper. (Contains 1 table.)
