From Pharmacy to Shelf: Consumer Awareness of Nutraceutical Potency and Noxiousness

Abstract

Nutraceuticals have emerged as a rapidly expanding segment within the global healthcare and wellness industry, bridging the gap between pharmaceuticals and functional foods. Increasing consumer inclination toward preventive healthcare, immunity enhancement, and natural therapeutic alternatives has significantly elevated the demand for nutraceutical products across retail pharmacies and commercial shelves. However, despite their widespread acceptance, consumer understanding regarding nutraceutical potency, efficacy, dosage standardization, and potential noxious effects remains limited and inconsistent. Misleading marketing claims, inadequate regulatory harmonization, self-medication practices, and insufficient pharmacovigilance mechanisms further intensify concerns related to product safety and therapeutic reliability. This paper critically examines consumer awareness associated with nutraceutical effectiveness and toxicity, while exploring factors influencing purchasing behavior, label comprehension, trust in healthcare professionals, and perceptions of natural product safety. The study additionally evaluates regulatory challenges, quality assurance issues, contamination risks, herb–drug interactions, and adverse health outcomes linked with uncontrolled nutraceutical consumption. By integrating recent scholarly evidence and market trends, the paper highlights the urgent necessity for evidence-based consumer education, transparent labeling frameworks, and stronger regulatory surveillance to ensure safe and rational nutraceutical utilization in modern healthcare systems.
