What it does: This fiber is not absorbed or digested by the body. Instead, it serves as an inert bulking, anti-caking, and binding agent, helping to hold tablets together and maintain their consistency.
How it is used: Microcrystalline cellulose is primarily used to improve the physical structure of tablets, capsules, and powders, preventing them from breaking apart and ensuring uniformity in supplements and medications.
Natural sources and supplement forms: Cellulose naturally occurs in all plant foods as a structural component. Microcrystalline cellulose used in supplements is produced from purified wood pulp and typically appears as a fine white powder.
Why it appears in supplement formulas: Its main function is to stabilize tablets and capsules, providing mechanical strength and making accurate dosing possible throughout a product's shelf life.
What to know before use: Microcrystalline cellulose is generally recognized as safe, but large amounts may occasionally cause mild digestive discomfort such as bloating for sensitive individuals.
Interesting Fact
Microcrystalline Cellulose: Plant Fiber That Gives Structure
Microcrystalline cellulose is a purified, naturally occurring form of plant fiber derived from wood pulp. It’s not digested by the body but plays a valuable role in supplements by helping tablets hold their shape, preventing crumbling, and ensuring consistent dosage in each pill. You’ll also find cellulose naturally in fruits and vegetables as a structural component of plant cell walls.
