Biological Synergism in Whey Protein Concentrate Formulations Sweetened with Steviol Glycosides

Background and Objective: Innovative nutraceutical formulations of whey protein concentrate sweetened with steviol glycosides recently appeared with marketing for improving quality of life (QoL) in patients with non-communicable diseases (NCDs) and people with special food needs. Synergism between whey protein and stevia leaf extract evaluated in well-structured review was highlighted here to endorse the application of this combination in nutraceutical formulations. Materials and Methods: Well-structured publications with complete methodologies were studied thoroughly to extract the valuable updated data to be presented in an informative and concise way. Results: After the examination of the methodology and results of the well-structured publications concerned with the effect of mixing whey protein (concentrate or isolate) and steviol glycosides, it is noteworthy to mention and highlight the biological synergism noticed in vivo upon consumption of regular diets of formulations of whey protein concentrate with steviol glycosides sweetener. Conclusion: The current paper presents evidence-based facts about the biological synergism between whey protein and stevia leaf extract when mixed together in formulations for improving quality of life (QoL) in patients with non-communicable diseases (NCDs).
