Overview

Wheat dextrin is a form of soluble dietary fiber derived from wheat starch. It dissolves completely in liquids and has no taste or gritty texture, making it an easy way to increase daily fiber intake. As a prebiotic, it feeds beneficial gut bacteria, which can improve overall digestive health. It is often used to promote regularity, relieve constipation, and may help with blood sugar control.

Key Benefits

Improves Bowel Regularity

By absorbing water and adding bulk to the stool, wheat dextrin helps to promote regular, healthy bowel movements and can alleviate constipation.

Prebiotic Effects

Wheat dextrin acts as a prebiotic, meaning it serves as a food source for beneficial bacteria in the gut, such as *Bifidobacteria* and *Lactobacilli*, promoting a healthy gut microbiome.

Blood Sugar Management

Soluble fiber can slow the absorption of sugar, which may help to improve blood sugar control in individuals with diabetes or pre-diabetes.

Supports Satiety

Fiber can help you feel fuller for longer, which may aid in weight management by reducing overall calorie intake.

Dosage & How to Take

Start with a small dose and gradually increase to allow your digestive system to adjust. It is important to drink plenty of water when increasing fiber intake.
