Abstract

This study investigated the effect of 6-week supplementation of a probiotic strain Lactobacillus salivarius UBL S22 with or without prebiotic fructo-oligosaccharide (FOS) on serum lipid profiles, immune responses, insulin sensitivity, and gut lactobacilli in 45 healthy young individuals. The patients were divided into 3 groups (15/group), that is, placebo, probiotic, and synbiotic. After 6 weeks, a significant reduction (P < .05) in total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides and increase in high-density lipoprotein cholesterol was observed in the probiotic as well as in the synbiotic group when compared to placebo; however, the results of total cholesterol and LDL-cholesterol were more pronounced in the synbiotic group. Similarly, when compared to the placebo group, the serum concentrations of inflammatory markers such as high sensitivity C-reactive protein, interleukin (IL) 6, IL-1β, and tumor necrosis factor α were significantly (P < .05) reduced in both the experimental groups, but again the reduction in the synbiotic group was more pronounced. Also, an increase (P < .05) in the fecal counts of total lactobacilli and a decrease (P < .05) in coliforms and Escherichia coli was observed in both the experimental groups after 6 weeks of ingestion. Overall, the combination of L salivarius with FOS was observed to be more beneficial than L salivarius alone, thereby advocating that such synbiotic combinations could be therapeutically exploited for improved health and quality of life.
