What Is Prebiotic GOS (Galactooligosaccharides) and Why Is It in the Sleep Probiotic+?Updated an hour ago
The Codeage Sleep Probiotic+ includes Prebiotic GOS (Galactooligosaccharides) as part of its 500mg Sleep Blend alongside L-Theanine. GOS is one of the most well-researched prebiotic ingredients in the dietary supplement and functional food industry and is commonly included in probiotic formulas as a complementary prebiotic fiber.
What Are Galactooligosaccharides (GOS)?
Galactooligosaccharides — commonly abbreviated as GOS — are a class of prebiotic fibers derived from lactose through an enzymatic process. They belong to the broader category of oligosaccharides (short-chain carbohydrates) and are naturally found in small amounts in human breast milk, cow's milk, and certain dairy products.
GOS are non-digestible by human digestive enzymes, meaning they pass through the small intestine largely intact and reach the colon, where they serve as a fermentable substrate — or food source — for beneficial gut bacteria.
What Is a Prebiotic?
A prebiotic is a substrate that is selectively utilized by host microorganisms and confers a health benefit. In simpler terms, prebiotics are compounds that feed and support the growth of beneficial bacteria already present in the gut microbiome. GOS is one of the most studied prebiotics in both infant nutrition and adult gut health research.
The International Scientific Association for Probiotics and Prebiotics (ISAPP) provides comprehensive resources on prebiotic definitions, research, and applications.
Why Pair GOS With Probiotics?
Pairing a prebiotic (GOS) with a probiotic blend is a standard approach in advanced gut wellness supplement formulations. The prebiotic provides a fermentable substrate that feeds the probiotic strains, while the probiotic strains contribute live bacteria to the gut environment. Including both in a single formula is commonly referred to as a "synbiotic" approach.
Does GOS Contain Dairy?
GOS is derived from lactose — a milk sugar — through enzymatic processing. As a result, GOS-containing products may be associated with dairy. The Sleep Probiotic+ carries a milk allergen declaration. Individuals with dairy allergies or lactose intolerance should consult a healthcare professional before use.
