*4.5. Oral Glucose Tolerance Test (OGTT) in Both Studies*

After the fasted blood sample was collected, participants consumed a glucose drink containing 75 g of glucose. Participants then waited for 2 h and remained rested with minimal activity during this period. Then, after 2 h, another blood sample was taken into an EDTA tube via venipuncture. These samples were analyzed for glucose (Study 1 and 2) and insulin levels (Study 1).
