How Organic Resistant Dextrin Improves Your Blood Glucose and Insulin Levels

Organic resistant dextrin is a type of soluble dietary fiber derived from organic corn starch. It is also known as soluble corn fiber or resistant maltodextrin. It has a low molecular weight, a high dextrose equivalent, and a slightly sweet taste. It is easily soluble in water and can be added to various foods and beverages without affecting their original flavor.

Organic resistant dextrin has been shown to have beneficial effects on blood glucose and insulin levels in several studies. In this article, we will review how organic resistant dextrin can help regulate blood glucose levels, increase insulin sensitivity, and modulate the gut microbiota.

How organic resistant dextrin regulates blood glucose levels

Blood glucose levels are influenced by the type and amount of carbohydrates consumed, as well as the rate of digestion and absorption of carbohydrates in the gastrointestinal tract. Carbohydrates can be classified into two categories: digestible and non-digestible. Digestible carbohydrates are broken down into glucose and other simple sugars by enzymes in the mouth, stomach, and small intestine. Non-digestible carbohydrates, such as dietary fiber, are not broken down by enzymes and pass through the small intestine to the large intestine, where they are fermented by bacteria.

Organic resistant dextrin belongs to the non-digestible category of carbohydrates. It can help regulate blood glucose levels by slowing down the digestion and absorption of carbohydrates, reducing the postprandial glucose and insulin spikes. Postprandial glucose and insulin spikes are associated with increased risk of type 2 diabetes, cardiovascular disease, and obesity. By lowering the glycemic index and glycemic load of foods, organic resistant dextrin can help prevent or manage these chronic diseases.

How organic resistant dextrin increases insulin sensitivity

Insulin is a hormone that helps glucose enter the cells to be used for energy or stored for later use. Insulin sensitivity refers to how well the cells respond to insulin. When the cells are insensitive to insulin, they do not take up glucose efficiently, resulting in high blood glucose levels and low cellular energy. This condition is called insulin resistance and is a major factor in the development of type 2 diabetes.

Organic resistant dextrin can increase the sensitivity of insulin receptors, enhancing the uptake of glucose by the cells and lowering the fasting blood glucose levels. This effect may be mediated by the short-chain fatty acids (SCFAs) produced by the fermentation of organic resistant dextrin in the large intestine. SCFAs can activate receptors on the cell membrane that regulate glucose metabolism and insulin signaling. SCFAs can also inhibit the production of glucose by the liver, reducing the hepatic glucose output.

How organic resistant dextrin modulates the gut microbiota

The gut microbiota is the collection of microorganisms that live in the digestive tract. It plays an important role in human health and disease, affecting various aspects of metabolism, immunity, and behavior. The composition and function of the gut microbiota are influenced by many factors, such as diet, genetics, environment, and medication.

Organic resistant dextrin can modulate the gut microbiota, promoting the growth of beneficial bacteria that can produce SCFAs, such as Bifidobacterium and Lactobacillus. These bacteria can improve glucose metabolism and insulin signaling, as well as enhance the intestinal barrier function, reduce inflammation, and modulate the immune system. By altering the gut microbiota, organic resistant dextrin can also affect the production and secretion of hormones and neurotransmitters that regulate appetite, satiety, mood, and cognition.


Organic resistant dextrin is a safe and effective ingredient for improving blood glucose and insulin levels, especially for people with diabetes or prediabetes. It can help prevent or delay the onset of diabetes complications, such as cardiovascular disease, kidney disease, eye disease, and nerve damage. It can also support weight management, appetite control, and digestive health.

Organic resistant dextrin is a natural and healthy way to increase the intake of dietary fiber and to manage blood glucose and insulin levels. It can be easily incorporated into the daily diet, as it is compatible with various food applications, such as snack bars, protein balls, baked goods, confectionery, ice cream, and beverages. It is also available in organic, non-GMO, and gluten-free versions, meeting the consumer demand for clean label products.

Organic resistant dextrin is a valuable addition to the functional food market, as it offers multiple health benefits and a superior sensory profile. It is a promising ingredient for the development of innovative and nutritious products that can help consumers achieve their health and wellness goals.
