Silicon dioxide is a naturally occurring compound found in sand, quartz, and many plants... & it's used in some of our supplements in small amount & acts as a natural flowing agent, preventing the powder from sticking or clumping during manufacturing. Being a natural compound & used in such small quantities in our supplements, we have no issues with this.
But some brand may use it in larger quantities as a bulk agent. Something to watch for is the synthetic form 'colloidal anhydrous silica', which we would always stay away from.
