Banaba is the best source of corosolic acid, a known agent that helps absorb glucose into blood cells according to Japanese studies. In humans with type II diabetes, banaba extract, at a dose of 16-48mg per day for 4-8 weeks, has been shown to be effective in reducing blood sugar levels (5%-30% reduction) and maintaining tighter control of blood sugar fluctuations. An interesting side-effect of tighter control of blood sugar and insulin levels is a significant tendency of banaba to promote weight loss (an average of 2-4 lbs. per month) without significant dietary alterations. It is likely that modulation of glucose and insulin levels reduces total caloric intake somewhat and encourages moderate weight loss.
