Regulatory and Safety Challenges in Nano-Targeted Nutraceutical Development
Synopsis
Abstract
Nanotechnology presents newer ways for nutraceutical preparation of site-specific delivery, stability, and bioavailability of the bioactive compounds. Nevertheless, they face the major regulatory and safety issues, therefore limiting their commercial and clinical application. Given some nanoscale properties such as altered pharmacokinetics, surface reactivity, and cellular absorption, traditional approaches of safety evaluation are questioned. Existing regulatory systems are disparate, without unified definitions, uniform testing criteria, and harmonized approval processes for nanomaterials in food and health foods. Issues of long-term toxicity, biodistribution, off-target toxicity, and cumulative exposure also add to complexity in risk assessment. The current paper critically assesses the gaps in regulation and safety concerns surrounding nano-targeted nutraceuticals, with a focus on the importance of coordinating globally aligned guidelines that include nanotoxicology, risk benefit considerations, and consumer protection. Creating strong, science-informed policies is key to maintaining a balance between innovation and safety, allowing for the safe development of nanotechnology in the nutraceutical industry.
