Summary

This study looks at how a short-term plant-based diet or supplements (omega-3, curcumin, or probiotics) change levels of butyrate—a healthy gut compound—in people with smoldering multiple myeloma or MGUS. About 200 participants will be randomly assigned to one of the diet or supplement groups for two weeks. The goal is to understand how these dietary changes affect gut bacteria, not to treat the disease directly.
