DOES IT WORK?
Microcrystalline cellulose is the supplement industry's most-used filler. It's purified plant fiber (usually from wood pulp or cotton) that helps tablets hold their shape, flow through manufacturing equipment, and bulk out capsules. Completely inert, completely safe, completely boring. Does its job well.
