Heart shield: antioxidant may guard against chemo side effect
NCT ID NCT06703593
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether taking alpha lipoic acid, a common antioxidant, could prevent heart damage caused by the chemotherapy drug doxorubicin in breast cancer patients. 80 women starting their first round of doxorubicin-containing chemotherapy were enrolled. Researchers measured heart function and blood markers of heart strain to see if the supplement offered protection.
