Microcrystalline Cellulose	Filler/Binder	No	Refined wood pulp used as a filler and binder. Generally inert and well-tolerated.
Silicon Dioxide	Glidant	No	A mineral (silica) used to improve powder flow during tablet manufacturing. Also called colloidal silicon dioxide.
Sodium Starch Glycolate Type A	Disintegrant	No	A modified starch (typically potato-derived) that swells rapidly in water, helping tablets break apart for faster drug release.
Talc	Glidant/Lubricant	No	A mineral used to improve powder flow in manufacturing.
Titanium Dioxide	Colorant/Opacifier	No	A white pigment used for coating opacity. Under regulatory review in some countries.
