Benefits of Inulin

Inulin, also known as a polysaccharide, is a soluble fibre classed as a fructan. Fructans are chains of fructose indigestible by our body, but loved by the good bacteria in our gut flora. Since our body cannot digest the fructans, inulin has very little impact on blood sugar and unlike other sugars is not insulemic.

A daily dose of the recommended intake of inulin promotes immune system function, supports the cardiovascular system, and enhances the absorption of minerals in the body. Furthermore inulin can be vital for weight loss or calorie reduced diets, works as a digestive aid, and can be invaluable for diabetics.

Immune System

(Check Studies)

  • By feeding and enhancing bifidobacteria in the colon, inulin has been shown to stimulate the immune system and inhibit harmful pathogens in the intestine that could otherwise harm the gut mucosa.
  • Studies also show that diets containing inulin reduce colon cancer risk by reducing the impact of genotoxins.
  • Lowers triacylglycerol in the blood, reducing the risk of heart disease.

Mineral Absorption

(Check Sources)

  • Consuming inulin may enhance the absorption of calcium, magnesium, zinc and iron in the colon.
  • By absorbing more calcium, inulin helps diminish the loss of bone tissue, aiding in the prevention of osteoporosis.

Weight loss

(Check Studies)

  • Daily consumption of inulin reduces appetite, making weight loss easier!
  • Inulin`s effect on the gut microbiota can help stem obesity.
  • Inulin has a sweet taste making it very useful as a sugar replacement.
  • Inulin thickens and gels making it fantastic thickening agent and substitute for fat.


(Check Studies)

  • Inulin increases the regularity and volume of stool, diminishing constipation and diarrhea.
  • Inulin can help prevent relapses in c. difficile associated diarrhea.
  • Diets containing inulin help reduce the risk of metabolic diseases by releasing amino acid chains in the gut and regulating digestion.

Benefits for Diabetics

(Check Studies)

  • Intake of inulin may help prevent diseases related to blood lipids and blood glucose.
  • Diets containing inulin can help reduce lipoprotein.
