🌽 High Amylose Corn Resistant Starch (RS2)

Natural Dietary Fiber Ingredient for Gut Health, Low GI Foods & Functional Nutrition

High Amylose Corn Resistant Starch (RS2) is a natural dietary fiber derived from high-amylose corn. It resists digestion in the small intestine and reaches the colon, where it acts as a prebiotic fiber, supporting gut health and metabolic balance.

As a low glycemic index (GI) carbohydrate, RS2 is widely used in functional foods, dietary supplements, and healthy formulations targeting digestive health, weight management, and blood sugar control.

Chibio Biotech supplies high-quality RS2 resistant starch with high amylose content and dietary fiber, ensuring stable performance for food and nutrition applications.
