Progressive Laboratories Multi-Scorb is a sustained release form vitamin C that does not upset the digestive system, even in high doses.
Mineral ascorbates do not lower stomach pH or cause irritation. Since the body can only absorb a certain amount of the vitamin during a given period of time, sustained release also allows for better absorption.
