Use of dietary supplements containing polyvalent cations and antacids among people living with HIV and its impact on viral suppression.

Dietary supplements and medications containing polyvalent cations can interact with integrase strand transfer inhibitors (INSTIs) and decrease exposure to INSTIs. In this cross-sectional study of 513 people living with HIV (PLWH) who were on stable antiretroviral therapy, 57.5% and 6.6% reported concurrent use of dietary supplements and antacids, respectively. In the multivariable analysis, the use of antacids, but not dietary supplements containing polyvalent cations, was associated with HIV viremia in PLWH who received INSTI-based ART.
