The Effect of Morinda citrifolia L. Fruit Juice on the Blood Sugar Level and Other Serum Parameters in Patients with Diabetes Type 2.
Algenstaedt P, Stumpenhagen A, Westendorf J.
Ingesting Tahitian Noni Juice for 8 weeks resulted in a significant average decrease of fasting blood sugar levels of 20 type 2 diabetes patients. But it did not cause hypoglycemia in normoglycemic patients. Further, noni juice reduced the mean HbA1c values significantly. Decreases in highly sensitive CRP values occurred in patients with initially high levels, whereas no change was observed in patients with normal initial values. Average C-peptide levels also increased after four weeks in patients with low starting levels, but not in patients with higher levels.
