Overview

Prebiotics are a type of non-digestible fiber that acts as food for the beneficial bacteria (probiotics) in your gut. By selectively stimulating the growth and activity of these good bacteria, prebiotics help to improve the balance of the gut microbiome. This can lead to a wide range of health benefits, including improved digestion, enhanced immune function, and better nutrient absorption.

Key Benefits

Promotes a Healthy Gut Microbiome

Prebiotics provide fuel for beneficial gut bacteria, helping them to thrive and outcompete harmful bacteria.

Improves Digestion and Regularity

By supporting a healthy gut environment, prebiotics can help to alleviate digestive issues like constipation and improve overall bowel function.

Enhances Immune Function

A healthy gut microbiome is closely linked to a strong immune system, and prebiotics can help to support this connection.

Dosage & How to Take

A typical starting dose for prebiotic supplements is 3-5 grams per day. It is often recommended to start with a lower dose and gradually increase it to allow the digestive system to adapt.
