Manufacturers use pregelatinized corn starch to bind ingredients and control how tablets or capsules break apart. The processing improves its flow and binding properties. It serves as an excipient only, not an active ingredient, and offers no therapeutic effect.
You take this starch only as part of a finished supplement or medication. It acts as an inert filler, so there is no standalone dosage. The amount in a product varies by formulation.
Pregelatinized corn starch is generally recognized as safe for most people. However, individuals with corn allergies or sensitivities should avoid products containing this ingredient.
