Zinc has been widely used to reduce the duration of diarrhea in AGE, especially for children. While it is recommended as a supplement in AGE, it seems to be most useful in lower income areas where nutritional deficiencies are more common. Smectite is a type of clay mineral that binds loose stools. Using smectite alongside zinc supplementation can shorten the duration of symptoms.[1]
Probiotics are often recommended in the case of AGE, although exact strains and dosages are still unclear. Saccharomyces boulardii, a type of probiotic yeast, might be more useful for shortening the duration of diarrhea than other strains, especially if taken with zinc.[1] [2]
