Abstract

In recent years, the focus on improving well-being through natural solutions, such as dietary adjustments to improve the composition and functionality of the microbiota, has gained prominence. This study explored the effects of a zinc-enriched postbiotic of whole-cell yeast strains (Saccharomyces boulardii ABB S3, Kluyveromyces marxianus ABB S8, and Saccharomyces cerevisiae ABB S6) on metabolic health and gastrointestinal well-being in resistance-training individuals. Over a 30-day period, 18 participants who experienced gastrointestinal discomfort and were not using other dietary supplements underwent evaluation. The intervention aimed to assess changes in serum zinc levels, protein metabolism indicators, and gastrointestinal health, using a repeated measures design for comprehensive data analysis. Results showed a significant increase in serum zinc levels and improvements in protein metabolism markers, alongside reduced gastrointestinal discomfort. These findings underline the efficacy of zinc-enriched postbiotic supplementation in enhancing metabolic health, and suggest that such targeted nutritional interventions can significantly benefit exercise performance and general well-being. The study's outcomes support the potential of incorporating postbiotics into dietary strategies for health maintenance, offering a promising direction for future research in nutritional science and the management of exercise-induced gastrointestinal symptoms.
