Importantly, these treatments were generally well-tolerated, with no significant increase in all-cause dropouts compared to placebo, highlighting their suitability for clinical use in managing agitation in individuals with ASD or ID.
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
Based on multiple meta-analyses showing ~35% pain reduction. Studies primarily used micronized formulations which may have better bioavailability than standard forms. Most benefits observed within 4-6 weeks of treatment.
