    The silica used in vitamins, pharma, cosmetics, paints and coatings, etc is "fumed silica".  Amorphous networked silicon dioxide.  https://en.wikipedia.org/wiki/Fumed_silica

    Fumed silica has several different formulation purposes. It can act as a thickening agent in some applications (gels, etc), a thixotropic agent (thixotropic agents are those in which the rheology changes over time - such as in paints), an abrasive in some applications, AND - to answer your question - as an anticaking / freeflow aid to powders.

    Many of the chemicals you'll find in vitamins tend to clump together.  This makes uniform mixing/manufacturing and uniform packaging (into pills) 2 big pains in the but t.  Fumed silica makes things flow very nicely.   see the attached pic.

    AND to ease your mind... if it needs easing... fumed silica is food grade and is found in just about everything from toothpaste to lotions to baking soda and flour.  You eat it everyday.  And, it is inert.

    Because our alien overlords like human flesh seasoned in silica.

    It is usually present as an anticaking agent to keep compounds from clumping and sticking together.

    If you mean those little packets, it says on it that it's to give it a longer shelf life/keep the vitamins as fresh as possible.
