Patient safety requires understanding three fundamental principles about vitamin C supplementation. First, recognize the dose distinction: high-dose supplements exceeding 2,000 mg daily pose documented risks to anticoagulants, statins, and chemotherapy agents, while food sources of vitamin C are safe and beneficial. Second, implement practical timing strategies—separating supplement intake from medication by at least 2 hours minimizes absorption interference and metabolic conflicts. Third, and most critically, establish transparent communication with your healthcare team. Before initiating any new supplement or medication, inform your pharmacist and physician of all current supplement use, including vitamin C products. This simple disclosure allows healthcare providers to monitor drug levels, adjust dosing if necessary, and identify potential conflicts before they affect your health. Patients managing chronic conditions bear particular responsibility for this disclosure, as interactions can compromise treatment efficacy. Read the full article on GMJ Newsroom.
