Standardized Herbal Bioactives, Nutraceuticals, and Functional Foods for Metabolic Health

Metabolic health research increasingly focuses on dietary strategies that can help prevent or manage obesity, dyslipidemia, impaired glucose regulation, and type 2 diabetes mellitus. Herbal bioactives, nutraceuticals, and functional foods have shown potential through antioxidant, anti-inflammatory, hypoglycemic, hypolipidemic, and microbiota-modulating effects. Although these categories overlap, they are distinct: herbal bioactives are compounds of botanical origin; nutraceuticals are concentrated bioactive preparations — of plant or food origin — delivered in supplement form for benefits beyond basic nutrition; and functional foods are whole or fortified foods consumed as part of the normal diet. Even so, the evidence remains difficult to compare because plant materials and food matrices vary in composition, extraction methods, bioactive content, formulation, and dose. Important questions therefore remain regarding the relationship between chemical standardization, bioavailability, biological activity, and clinically meaningful outcomes. Recent studies have identified promising effects in cellular, animal, and human models, while also highlighting substantial variability in study design, product characterization, and safety assessment. Current approaches increasingly integrate chromatographic fingerprinting, marker-compound quantification, advanced delivery systems, gut–microbiota research, and translational clinical investigations. Nevertheless, robust evidence linking standardized bioactive preparations to reproducible nutritional and metabolic benefits is still limited, particularly over the long term and in diverse populations. Further interdisciplinary research is needed to establish reliable quality criteria, clarify mechanisms of action, and support safe and effective applications.This Research Topic aims to advance the understanding and application of standardized herbal bioactives, nutraceuticals, and functional foods for metabolic health. It will examine how phytochemical composition, processing, formulation, bioavailability, mechanisms of action, efficacy, and safety influence nutritional and metabolic outcomes. Particular attention will be given to studies that connect product characterization with physiological, microbiological, or clinical evidence and that identify the factors responsible for variability in response.To gather further insights into standardized herbal bioactives, nutraceuticals, and functional foods relevant to the prevention and management of metabolic disorders, we welcome articles addressing, but not limited to, the following themes: •Standardization and quality control of plant extracts and food-derived bioactives, including chromatographic fingerprinting and marker-compound quantification •Bioavailability, bioaccessibility, absorption, metabolism, and biotransformation of herbal and food-derived bioactives •Delivery systems, encapsulation, and formulation strategies to improve stability and dietary uptake •Gut–microbiota interactions and their contribution to the metabolic effects of bioactives •Mechanisms of action related to obesity, lipid metabolism, insulin resistance, glucose regulation, and inflammation •Cellular, animal, and human studies evaluating the efficacy of nutraceuticals and functional foods •Development and characterization of functional foods, fortified products, and dietary formulations with defined bioactive content •Safety, toxicology, dose–response relationships, interactions, and regulatory considerations•Herbal ingredients and functional foods for the prevention or management of type 2 diabetes mellitus and dyslipidemia•Sustainable sourcing, processing, and production of herbal bioactives and functional foods•Translational challenges, reproducibility, and clinical implementation of bioactive-based nutritional interventionsStudies focused solely on drug development or pharmaceutical formulation, without a clear nutritional dimension, fall outside the scope of this Research Topic.Appendix: Article typesWe welcome Original Research, Reviews, Systematic Reviews, and Perspectives.
