Summary

This study tested whether taking Coenzyme Q10, a natural antioxidant, can help prevent or reduce side effects from chemotherapy in breast cancer patients. Forty women newly diagnosed with breast cancer and about to start chemotherapy took either Coenzyme Q10 or a placebo. Researchers tracked common side effects like fatigue, nerve damage, nausea, and anemia to see if the supplement made a difference.
