Microcrystalline cellulose

Microcrystalline cellulose is a purified form of cellulose obtained by the partial hydrolysis of plant-derived cellulose, primarily sourced from wood pulp or cotton. It appears as a fine white powder and is one of the most widely used insoluble dietary fibres in the industry, alongside hemicellulose and lignin. As an insoluble fibre, microcrystalline cellulose is not broken down by human digestive enzymes. It passes through the gastrointestinal tract and contributes to normal intestinal transit by increasing the bulk of the food bolus. Its regular consumption fits within the context of a fibre-rich diet, associated with the maintenance of good digestive health. In the field of supplementation, microcrystalline cellulose is primarily used as a technological excipient: it acts as a bulking agent, anti-caking agent, texturiser, and thickener in the manufacture of tablets and capsules. Its safety is well established and it is recognised as a safe substance by European and international health authorities.
