< .05). A significant decrease was found in fasting blood sugar and HOMA-IR values compared with baseline in both groups. Furthermore, there was a significant increase in vitamin B12 and vitamin D values in the group receiving synbiotics compared with their baseline values. As a result of our study, both groups experienced similar weight loss and a decrease in BMI values. The vitamin B12 and vitamin D values of the group that took supplements increased significantly. The HOMA-IR values were significantly lower in both groups, albeit more in the synbiotic group. Changes in vitamin B12, vitamin D, and HOMA-IR values are extremely important for improving the health parameters in the long term.
