Summary

This study tests whether fucoidan, a supplement from brown seaweed, can prevent or reduce fatigue in people with gastrointestinal or gynecologic cancers who are starting chemotherapy. About 34 participants will receive either fucoidan or a placebo daily for up to 16 weeks. Researchers will track fatigue scores and other symptoms to see if the supplement makes a difference.
