    Banaba leaf extract contains a triterpenoid compound known as corosolic acid ?which has actions in stimulating glucose transport into cells. As such, banaba plays a role in regulating levels of blood sugar and insulin in the blood. For some people, fluctuations in blood sugar and insulin are related to appetite, hunger and various food cravings ?particularly craving for carbohydrates such as bread and sweets. By keeping blood sugar and insulin levels in check, banaba may be an effective supplement for promoting weight loss in certain individuals.
