Medical experts warn against unsupervised supplement use

Medical experts are warning against the unsupervised use of dietary supplements and over-the-counter medications due to risks of adverse interactions and organ damage. Rheumatologist Professor Anna Kuryliszyn-Moskal notes that individuals treating conditions like osteoarthritis may inadvertently cause harm if supplements interact with medications for hypertension or diabetes. She specifically cautioned against the frequent, high-dose use of paracetamol, which can lead to liver and kidney damage.

Furthermore, specialists emphasize that supplements lack the same level of pharmacological control and clinical testing as prescription drugs. Professor Jarosław Drobnik advised that relying on unverified alternative methods can delay necessary medical treatment.

Regarding digestive health, physician Raj Dasgupta highlighted that certain common supplements—including iron, calcium, magnesium, fish oil, vitamin C, probiotics, and protein powders—can cause gastrointestinal issues. For instance, iron supplements, particularly iron sulfate, are known to cause constipation, nausea, and abdominal pain, especially when doses exceed 45 mg daily. Experts recommend consulting a doctor to ensure proper dosage and to select more bioavailable forms of nutrients.
