The glucosamine sulfate in MSM with GS-500 is extracted from chitin, a hard, cellulose-like compound that is the main component in external shells of crustaceans such as shrimp.
Does MSM with GS-500 have any side-effects with use?
Very few side effects have been reported from MSM supplementation. In rare instances, there may be gastrointestinal discomfort and loose stools due to intake of large doses (i.e., several grams at a time). If GI upset occurs, it is recommended to divide the dose. Taking MSM in two or three doses throughout the day, after meals, may reduce the occurrence of GI upset.
