The use of Jerusalem Artichoke (Inulin) in supplements

Jerusalem artichoke is commonly used as an ingredient in supplements due to its potential health benefits. Inulin supplements are available in various forms such as capsules, powders, and extracts.

Jerusalem artichoke (inulin) is commonly used in probiotics and prebiotics supplements due to its prebiotic properties. Inulin acts as a food source for beneficial bacteria in the gut, promoting their growth and proliferation.

Weight management and gut health

Jerusalem artichoke, rich in fibre, can help keep you full and satisfied. The fibre it contains is a type of carbohydrate that the body cannot digest, and it moves through the intestines intact to serve as food for the bacteria in the colon[ii]. Jerusalem artichokes contain inulin fibre, which acts as a prebiotic and helps regulate bowel function while promoting the growth of beneficial bacteria, such as Bifidobacterium, leading to a healthier gut microbiome and potentially reducing inflammation while improving metabolism and immunity[iii][iv].

Despite having low caloric value, this type of fibre is essential for maintaining good health. It can increase feelings of fullness and promote satiety[v].

Cholesterol

The soluble fibre in Jerusalem artichoke may help to reduce cholesterol absorption as it passes through the digestive tract[vi].

Blood pressure

Jerusalem artichoke provides a good source of potassium, which can help regulate blood pressure and counteract the negative effects of excess sodium[vii].

Blood sugar

Jerusalem artichoke's inulin content can slow down the digestion of carbohydrates and promote healthy blood sugar levels by releasing sugar slowly without spiking. A 2015 study found that inulin may benefit individuals with prediabetes by acting as a potential blood sugar stabiliser when consistently present in the diet over time[viii].

Precautions

Jerusalem artichoke is known for its high inulin content, which can cause digestive discomfort such as gas, particularly for some people with certain gut conditions. If you experience such discomfort, it may be wise to limit your intake until your body adjusts. Moreover, since Jerusalem artichoke contains fructan, those who are fructan intolerant or on a low-FODMAP diet should avoid consuming it[ix].

Interactions

Inulin is not currently known to interact with any medications or herbs[x].
