The efficacy of camel milk to treat diabetes has been shown recently, especially in experimental animals and in patients with diabetes type 1 (T1DM), whereas studies on patients with type 2 diabetes mellitus (T2DM) are limited. In this clinical trial, 60 patients with T2DM who used oral antidiabetic drugs were assigned into two groups; group 1 received—in addition to the antidiabetic prescribed medicines—500 mL of raw camel milk divided equally two times/day (fasting in the morning and the night) for three months. Group 2 was treated during the same period only by the oral antidiabetic medicaments without consumption of camel milk. A significant decrease was shown in fasting blood glucose (FBG) (from 9.89 ± 0.98 to 6.13 ± 0.55 mmol/L) and postprandial glucose (PPG) (from 15.89 ± 4.34 to 7.44 ± 1.02 mmol/L) in the group 1. A significant decline (P
