Diabetes-Specific Formula on Long Term Glycemic Control

This is a randomized, controlled, parallel study. Eligible participants will be randomly allocated (at 1 :1 ratio) to one of two groups: DSF group or control group.The total expected duration of the study is 97 days.

There are two periods in the study:

i) "Run-in Period" (Study Days -6 to -1): participants will wear the CGMS:Continuous Glucose Monitoring System (FreeStyle Libre Pro) and will be asked to follow and track their diet and physical activity on a daily basis.

ii) "Intervention Period" (Study Days 0 to 90): participants will be randomized into one of the two groups (n = 125 per group): DSF group or control group.

• The participant is willing to refrain from taking non-study diabetes-specific formulas over the entire course of the study
