  • Bitter melon notably contains phyto-nutrient, polypeptide-P, a plant insulin known to lower blood sugar levels. In addition, it composes hypoglycemic agent called charantinCharantin increases glucose uptake and glycogen synthesis inside the cells of liver, muscle and adipose tissue. Together, these compounds may have been thought to be responsible for blood sugar levels reduction in the treatment of type-2 diabetes.
  • Fresh pods are an excellent source of folates, carrying about 72 µg/100g (18% of RDA). Vitamin folate when taken by mothers during their early pregnancy time, would help reduce the incidence of neural tube defects in the newborn babies.

Together, these compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging, cancers and various disease processes.
  • Bitter melon stimulates easy digestion and peristalsis of food through the bowel until it is excreted from the body. Thus, it helps in relieving indigestion and constipation problems.
  • In addition, it is a moderate source of B-complex vitamins such as niacin (vitamin B-3), pantothenic acid (vitamin B-5), pyridoxine (vitamin B-6) and minerals such as iron, zinc, potassium, manganese and magnesium.
