INTRODUCTION:

The development of nutraceuticals or dietary supplements begins with identifying metabolic dysfunctions and exploring how targeted nutrition can help prevent, manage, or resolve them. These formulations often contain bioactive compounds such as fatty acids, phenolic compounds, prebiotics, postbiotics, and peptides¹. Nutraceuticals derived from food sources have demonstrated pharmacological benefits, including positive effects on brain metabolism. Such bioactives can be obtained either through whole foods or dietary supplements containing purified constituents, with evidence showing improvements in brain health through their use².

In recent years, there has been a decisive transition from conventional analytical techniques to green and sustainable methodologies. These “going green” strategies, akin to the principles of sustainable development, aim to address environmental challenges, support economic and social goals, and minimize the negative impacts of planning and decision-making processes³. Conventional approaches often pose environmental burdens and raise ethical concerns, particularly in healthcare and research, where inadequate patient information may lead to overtreatment or misinterpretation. Additionally, the equitable allocation of healthcare resources remains a critical ethical challenge⁴.

In the health-food and supplement industries, the demand for innovative, eco-friendly analytics is growing. Traditional food quality testing methods require substantial time, energy, and sample preparation. Incorporating biomarkers to detect nutrient deficiencies, metabolic imbalances, or genetic predispositions, such as MTHFR polymorphisms, allows for personalized supplementation, thereby enhancing efficacy and safety while minimizing the risks of indiscriminate use. This review provides a comprehensive examination of nutraceuticals, tracing their evolution, categorization, and mechanisms of action across diverse products such as probiotics, herbal extracts, functional foods, and dietary supplements⁵. It also assesses global regulatory frameworks, underscoring the importance of harmonization to ensure safety, efficacy, and public health protection through rigorous quality standards⁶.

The Nutraceutical Boom: Demands and Analytical complexities:

The global nutraceutical sector is witnessing unprecedented growth, driven by increasing consumer preference for preventive healthcare, rising chronic disease incidence, and a shift toward personalized nutrition. Defined as products that provide physiological benefits or protection against chronic conditions, nutraceuticals are used to enhance longevity, improve health, and delay aging⁷. However, a universally accepted definition remains elusive due to variations in global regulatory frameworks governing safety, efficacy, and marketing. This regulatory diversity, coupled with growing healthcare costs, is pushing both industrialized and developing nations toward preventive strategies and tailored supplementation⁸.

These products encompass a diverse range of bioactives. Polyphenols, classified into flavonoids and non-flavonoids, are valued for antioxidant and protective properties. Flavonoids such as anthocyanidins, chalcones, flavonols, flavones, flavanones, and isoflavones defend plants from environmental stress, while non-flavonoids like stilbenes (resveratrol), diarylheptanoids (curcumin), lignans, and xanthones demonstrate varied pharmacological benefits^9,10. Probiotics, as defined by WHO and FAO, can modulate immunity and improve gastrointestinal health^11,12. Essential omega-3 fatty acids, ALA, EPA, and DHA, must be obtained from the diet, yet clinical evidence on certain applications remains mixed. Vitamins contribute to immune regulation, antioxidant defense, and metabolic balance^13,14, while bioactive peptides, typically <6 kDa, support functional food development and disease prevention.

Despite their promise, nutraceuticals present significant analytical complexities. Matrix diversity, ranging from plant material and oils to edible formulations, complicates extraction and quantification, necessitating matrix-specific, standardized methods. Emerging techniques like capillary electrophoresis combined with miniaturized solid-phase extraction show potential for improved recovery and precision¹⁵. Bioavailability remains a persistent challenge due to poor water solubility and compound instability, which can be addressed through various approaches, including salification, complexation, micronisation, nanoemulsification, cocrystal formation, and amorphous solid dispersions. Stability issues, including drug-excipient incompatibility and thermal or photodegradation, require robust chromatographic, spectroscopic, and thermal analyses¹⁶.

Variability in natural product composition further complicates quality control, often violating statistical assumptions like stationarity, isotropy, and ergodicity, thus demanding adaptive analytical models^17,18. Additionally, market demand for “clean-label” products, driven by heightened post-COVID-19 food safety awareness, has amplified the call for transparent, traceable analytics. However, reformulating products to remove artificial additives presents cost and performance challenges, particularly in identifying effective natural preservatives ¹⁹. Ensuring labeling transparency is now essential for informed consumer choice and fostering trust.

Why Go Beyond Chromatograms?

Traditional analytical platforms, while long-standing in nutraceutical evaluation, present multiple operational and environmental challenges that drive the need for more sustainable, efficient alternatives. High-performance thin-layer chromatography (HPTLC) offers advantages over many older techniques, including lower solvent usage, high precision, accuracy, and the ability to handle complex samples with reduced environmental impact. Although often considered an advancement over conventional thin-layer chromatography (TLC), HPTLC still depends on stationary phase characteristics, such as uniform particle shape and size, to achieve effective separation ^20,21. Gas chromatography–mass spectrometry (GC-MS), another standard technique, requires significant infrastructure, high-purity helium, and considerable resources, limiting its practicality in some contexts. Its performance in non-targeted metabolomics can be hindered by matrix complexity, whereas newer technologies such as GC×GC-MS and GC–ion mobility spectrometry (GC-IMS) improve sensitivity, analyte coverage, and environmental efficiency^22,23.

These traditional methods also carry environmental costs. Solvent-intensive processes contribute to waste generation and require costly disposal or recycling systems²⁴. Improper disposal of agricultural biowaste releases harmful gases and can contaminate water with pesticides, fungicides, and heavy metals²⁵. Energy consumption in nutraceutical production further compounds environmental pressures, but integrating renewable energy sources and waste valorization, such as using crude glycerol or maize steep liquor to cultivate oleaginous fungi for PUFA production, can significantly reduce costs and environmental footprint^26,27.

Beyond environmental impact, research processes often suffer from inefficiencies. Conventional clinical trial protocols can be slow, costly, and overly complex, delaying results and hindering innovation. Streamlined designs, removal of non-core steps, and innovative trial planning have been shown to reduce Phase III procedure design time from months to weeks²⁸.

These limitations are accelerating the adoption of decentralized, real-time, and eco-friendly analytical strategies. By enabling data processing at the source, edge intelligence reduces data transfer requirements, conserves energy, and enhances responsiveness²⁹. In nutraceutical manufacturing, adopting sustainable sources for critical compounds, such as PUFAs, supports environmental goals while lowering production expenses, with agro-industrial residues offering viable, renewable feedstocks for microbial cultivation³⁰. Collectively, these trends signal a decisive move toward analytical practices that are not only technologically advanced but also environmentally responsible.

Green Analytical Chemistry: Concepts and Metrics:

Green Analytical Chemistry (GAC) emerged in 2000 as a specialized branch of green chemistry, acting as a catalyst for sustainable advancements in analytical science. Rooted in the 12 principles of green chemistry outlined by Anastas and Warner in 1998, GAC emphasizes methods that minimize environmental impact while ensuring analytical accuracy. Key principles include tailoring methods to meet synthetic chemistry needs, minimizing sample handling, conducting in situ measurements, integrating processes to reduce energy and reagent use, favoring miniaturization and automation, avoiding derivatization, preventing or effectively managing analytical waste, promoting multi-analyte techniques, reducing energy demands, utilizing renewable-source chemicals, replacing or eliminating toxic reagents, and enhancing operator safety^31,32.

Several tools have been developed to assess the “greenness” of analytical methods. The Analytical Eco-Scale assigns penalty points for factors such as reagent and solvent consumption, associated hazards, energy requirements, occupational risks, and waste generation, producing a score by subtracting penalties from an ideal value³³. The Green Analytical Procedure Index (GAPI) uses a color-coded pictogram to evaluate the environmental impact of each procedural step, categorizing them as green (low impact), yellow (medium impact), or red (high impact), and is widely applied in nutraceutical research^34,35. Similarly, the AGREE software tool offers a comprehensive and user-friendly assessment of analytical safety and environmental performance³⁶.

Practical comparisons highlight GAC’s potential. For example, ultrasound-assisted extraction (UAE) demonstrates significant sustainability advantages over conventional heating, including reduced solvent use, faster processing, and higher extraction efficiency. In contrast, high-performance liquid chromatography (HPLC), though offering reproducibility and sensitivity in applications such as synthetic dye detection, remains resource-intensive³⁷. Environmentally optimized spectrophotometric methods have been developed for compounds like curcumin and silybin, applying Analytical Quality by Design (AQbD) principles, using ethanol as a solvent, and measuring at 419 nm and 288 nm, respectively. These methods have been evaluated using multiple greenness assessment tools, demonstrating resilience and reduced ecological footprint³⁸.

Green Extraction Techniques for Bioactive Compounds:

Modern extraction methodologies are increasingly focusing on sustainability, combining efficiency with environmental responsibility. Ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) exemplify cost-effective, eco-friendly techniques capable of delivering higher yields of bioactive compounds compared to traditional methods. UAE relies on the generation of acoustic cavitation along with thermal and mechanical effects produced by ultrasonic waves, which expand and contract the treated material. This process enhances the release of bioactives while minimizing solvent use and extraction time, resulting in improved yields over conventional approaches³⁹.

Similarly, MAE has gained attention in research and industrial applications for its ability to extract valuable constituents from plant materials. Its mechanism involves the interaction of microwave radiation with polar compounds and solvents, causing rapid oscillation of electric and magnetic fields. This alters cellular structures, facilitating efficient compound release while reducing processing times compared to conventional heating⁴⁰.

Supercritical fluid extraction (SFE) offers another sustainable alternative, utilizing supercritical fluids to selectively isolate bioactive molecules from renewable sources such as medicinal, aromatic, and herbal plants. Its applicability extends to macro- and microalgae, making it a versatile, economically viable green technology^41,42. Pressurized hot water extraction (PHWE) is likewise a promising approach, enabling the recovery of proteins, polysaccharides, and phenolic compounds without relying on organic solvents. By adjusting water’s solvent properties through temperature control, PHWE offers a clean, adaptable extraction medium⁴³.

In recent years, natural deep eutectic solvents (NaDES) have emerged as an innovative solution, offering tunable properties, biodegradability, and low toxicity. Widely used as reaction media, catalysts, or pretreatment solvents, NaDES improve solubility, stability, and bioavailability in pharmaceutical applications. They have been shown to outperform conventional solvents such as ethanol in extracting phenolics from Sideritis taxa, further highlighting their potential as a sustainable alternative^44,45.

Smart, Miniaturized, and Solvent-Free Analytical Approaches:

In nutraceutical analysis, the adoption of compact, solvent-free, and intelligent analytical systems is accelerating due to their cost-effectiveness, operational efficiency, and reduced environmental footprint. Miniaturized platforms such as microfluidic chromatography and capillary electrophoresis enable rapid testing with minimal sample and reagent requirements, making them particularly suitable for assessing nutraceutical components like vitamins, polyphenols, and amino acids, thereby ensuring product safety and efficacy⁴⁶. Smart strategies in this domain include the use of nanotechnology for encapsulating nutraceuticals to enhance bioavailability, as well as personalized nutrition approaches tailored to genetic profiles⁴⁷.

Recent innovations have explored portable detection platforms for compounds such as polyphenols, antioxidants, and amino acids. Amino acids, which contribute to peptide and protein synthesis as well as flavor development, can be assessed using colorimetric microbead-based sensors containing ferric ions that react visibly with target compounds⁴⁸. Antioxidant monitoring, critical for preventing oxidative stress-related diseases, benefits from such rapid, field-deployable devices⁴⁹. Detection can be achieved through optical methods, such as gold nanoparticle-based colorimetry, where absorbance ratios correlate with analyte concentration, or electrochemical techniques employing thiol-modified aptamer-functionalized electrodes for sensitive trace analysis⁵⁰.

Lab-on-a-chip and micro total analysis systems (µTAS) are emerging as versatile tools for real-time, multi-analyte profiling of nutraceuticals. These technologies are increasingly integrated into nutrient profiling frameworks that inform public health policies, though their development requires careful consideration of method optimization and efficient extraction workflows ^51,52. Optical, electrochemical, and biosensor-based platforms also play a vital role in detecting bioactive compounds such as vitamins and flavonoids, whose concentration monitoring is essential for preventing deficiency- or excess-related disorder^53,54.

The integration of sensor networks into broader green platforms enables real-time monitoring, waste minimization, and enhanced reusability. In waste treatment applications, sensors aid in sorting, weight measurement, and fill-level detection, with data processed via IoT systems to optimize collection routes and improve resource efficiency. This approach, combining environmental monitoring with operational feedback, holds potential for minimizing waste generation in nutraceutical production and packaging⁵⁵.

Artificial Intelligence and Digital Green Labs:

Artificial intelligence (AI) and machine learning (ML) are increasingly recognized as transformative tools for optimizing green extraction and analytical workflows in nutraceutical research. By leveraging predictive algorithms, these technologies can determine environmentally sustainable operating parameters, such as temperature, pressure, and duration, while minimizing energy usage and reducing waste generation in alignment with the principles of green chemistry ⁵⁶. In silico modeling plays a crucial role in reducing waste from chromatographic processes, enabling the development of greener methods without the need for extensive physical trials.

Advanced spectral data interpretation is facilitated through artificial neural networks (ANNs), which simulate the human brain’s information processing to uncover complex relationships between variables. For instance, ANN models can link principal component scores to target chemical contents using supervised learning algorithms such as backpropagation, enabling highly accurate multivariate calibration. Partial least squares (PLS) regression provides a complementary approach, reducing dimensionality in hyperspectral datasets by isolating the most informative wavelengths, thereby addressing multicollinearity and enhancing signal-to-noise ratios. Additionally, chemometric deconvolution techniques ranging from pseudoinverse matrix methods to Tikhonov-Phillips regularization and maximum entropy approaches offer mathematically robust solutions to resolve overlapping spectral signals ⁵⁷.

Digital twin technology extends these capabilities by creating virtual replicas of analytical systems, enabling full workflow simulation prior to experimentation. These virtual models improve product design, process efficiency, and quality control while reducing physical resource expenditure⁵⁸. Efficiency is further enhanced by integrating minimal trial design strategies, which achieve statistically valid outcomes with the fewest experiments possible. Green data compression techniques also contribute to sustainability by reducing the storage and energy requirements for large analytical datasets, supporting environmentally conscious data management ⁶⁰.

Sustainable Spectroscopy: Non-Destructive, Real-Time Monitoring:

In metabolomic fingerprinting for food and nutraceutical analysis, Fourier-transform infrared (FTIR), near-infrared (NIR), and Raman spectroscopy are gaining prominence as environmentally sustainable alternatives to conventional chromatographic methods. Their non-destructive nature ensures that samples remain unaltered and intact during analysis, avoiding degradation and eliminating the need for extensive sample preparation or solvent use. These techniques also provide rapid, cost-effective, and efficient assessments while minimizing the consumption of expensive reagents and reducing waste, aligning with green analytical principles. This combination of efficiency, affordability, and minimal environmental footprint makes FTIR, NIR, and Raman particularly attractive for quality control and safety testing in sectors such as food and nutraceuticals, offering a viable replacement for solvent-intensive chromatographic approaches⁶¹.

The integration of chemometric methods further enhances their application in multicomponent nutraceutical evaluation, especially for complex botanical matrices that challenge conventional analysis. Statistical modeling combined with advanced spectroscopic techniques, such as FTIR and high-resolution nuclear magnetic resonance (NMR), has enabled clear differentiation between various nutraceutical raw materials⁶².

Advances in portable NIR spectroscopy extend these benefits to on-site analysis of herbal and natural supplements. These compact, affordable, and durable instruments facilitate in situ testing without damaging samples, enabling real-time monitoring of key quality attributes. Their ability to track compositional changes over time in plant-based products makes them valuable for assessing maturity, authenticity, and overall quality of herbal components directly in the field⁶³.

Blockchain and QR-Coded Analytical Transparency:

Ensuring analytical traceability from raw materials to the final retail product is increasingly vital for maintaining quality assurance and consumer trust in nutraceuticals. QR codes, when integrated into product packaging, offer a practical solution by linking to blockchain-based records that provide end-to-end transparency. This enables consumers to verify a product’s authenticity while allowing companies to monitor every stage of the supply chain, from sourcing to distribution. Such systems not only enhance visibility but also improve efficiency, support risk management, and strengthen accountability across the production process⁶⁴.

Blockchain technology further reinforces this framework by securely recording the results of green analytical procedures and making them accessible to stakeholders. Its decentralized, immutable, and tamper-proof characteristics ensure the accuracy and permanence of sustainability data, preventing unauthorized alterations. Access restrictions and orderly transaction processing within the distributed ledger safeguard the integrity of the recorded information, fostering confidence in environmental claims and promoting circular economy practices⁶⁵.

Practical examples illustrate the value of such transparency measures. Turmeric (Curcuma longa), widely cultivated across Southern Asia and valued for both culinary and medicinal applications, can be traced from wild or farmed sources to packaged, green-certified supplements. Similarly, ginseng, available as capsules, powdered extracts, teas, or dried herbs, can benefit from blockchain-enabled traceability, ensuring consumers receive authentic and sustainably sourced products while enabling producers to demonstrate compliance with eco-friendly and quality standards⁶⁶.

Circularity in Analytical Labs:

Adopting circular practices in analytical laboratories aligns with the broader principles of circular analytical chemistry, emphasizing waste reduction, resource efficiency, and environmental stewardship. The use of reusable glassware and biodegradable filters significantly decreases laboratory waste generation, lowering the environmental footprint while supporting a near waste-free operational model⁶⁷. Solvent recycling plays a critical role in minimizing hazardous waste and reducing the demand for virgin materials, with advances in biodegradable solvents derived from renewable resources further improving sustainability and feasibility in laboratory workflows⁶⁸.

Innovations in modular laboratory design contribute to both cost and energy savings. For instance, replacing multiple standalone analyzers with integrated modular systems has been shown to save tens of thousands of euros annually. Energy-efficient devices, including circular extraction systems, enhance process efficiency while reducing the carbon footprint associated with high-temperature operations. Reusability is a particularly impactful measure, with reusable laboratory utensils, regardless of whether they are glass or plastic, demonstrated to cut CO₂ emissions by up to eleven times compared with single-use plastics. Although initial costs may be higher, these reusable options yield substantial environmental and financial benefits over the long term ⁶⁹.

Sustainability in analytical labs can also be advanced through “waste-to-lab” strategies, which valorize plant residues and other agro-industrial by-products as valuable resources for method development. Such residues, often rich in high-value secondary metabolites, offer an opportunity to reduce raw material consumption while minimizing solvent use. This approach not only supports greener manufacturing processes but also mitigates environmental and health risks associated with unmanaged waste streams⁷⁰.

Limitations, Challenges, and Trade-Offs:

Sensitivity and Accuracy Compared to Conventional HPLC/LC-MS:

Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) has emerged as a highly advanced analytical platform within clinical and nutraceutical analysis due to its superior performance characteristics. Compared to conventional High-Performance Liquid Chromatography (HPLC) and single-stage Liquid Chromatography-Mass Spectrometry (LC-MS), LC-MS/MS offers markedly enhanced sensitivity and selectivity. Its ability to achieve substantially lower limits of detection (LOD) and quantification (LOQ) allows for precise measurement of analytes present at trace levels, often beyond the detection range of earlier-generation methods. The tandem mass spectrometric (MS/MS) configuration provides an additional dimension of molecular discrimination, thereby reducing background noise and improving quantitative reliability in complex matrices⁷¹.

Standardization and Regulatory Validation Hurdles:

A persistent barrier to the widespread adoption of novel analytical and extraction techniques, particularly those aligned with green chemistry principles, lies in the limited understanding among researchers of the procedural requirements for standardization and regulatory validation. These processes are typically segmented into three critical phases: method development, intra- and inter-laboratory validation, and final regulatory acceptance. Robust validation demands close collaboration between regulatory authorities and analytical laboratories, yet such engagement is frequently insufficient. Structural and procedural gaps persist in the drafting, harmonization, and implementation of normative and technical documentation, leading to delays in the recognition of alternative methodologies. This regulatory inertia mirrors similar challenges observed in other technical domains, such as urban planning, where organizational and policy-level inefficiencies can impede innovation adoption⁷².

Scalability of Green Approaches in Large Nutraceutical Industries:

Scaling green analytical and manufacturing practices from pilot studies to full-scale nutraceutical production facilities presents both strategic opportunities and operational challenges. From a technical standpoint, the integration of green technologies often requires substantial capital investment in advanced equipment, workforce training, and process re-engineering. While these requirements can pose a barrier to adoption, growing consumer preference for sustainable and eco-certified products creates a competitive incentive for industry leaders to transition toward greener models. The implementation of circular economy principles, emphasizing waste minimization, solvent recycling, and energy conservation, is particularly vital for maintaining competitiveness in high-volume manufacturing. Compliance with evolving environmental regulations is no longer optional but a market-access requirement, making early adoption of green approaches a strategic differentiator. Furthermore, optimization of energy consumption and material efficiency is essential not only for environmental stewardship but also for long-term economic viability in large-scale nutraceutical operations ⁷³.

Future Roadmap and Policy Implications:

The progression toward ISO certification for green analytical methodologies necessitates establishing robust, standardized metrics for assessing environmental sustainability while integrating eco-conscious practices directly into analytical workflows. Central to this effort is the adoption of environmentally benign solvents such as carbon dioxide, ionic liquids, subcritical and supercritical water, and deep eutectic solvents, which significantly reduce the ecological burden of sample preparation and analysis. By replacing volatile organic compounds, these solvents enable analytical operations that are both safer and more sustainable, aligning with broader global sustainability goals⁷⁴. Successful certification will require methodologies that preserve analytical precision and reproducibility while maintaining minimal environmental impact. Internationally recognized frameworks, such as those provided by ISO, offer a structured pathway for validating and certifying green analytical practices, thereby promoting global adoption. Achieving this balance between analytical performance and environmental responsibility remains a key challenge for future innovation.

Role of Green Chemistry in Nutraceutical Regulatory Frameworks (EFSA, FDA, FSSAI):

Embedding green chemistry principles into the regulatory frameworks of leading authorities such as the European Food Safety Authority (EFSA), the U.S. Food and Drug Administration (FDA), and the Food Safety and Standards Authority of India (FSSAI) is essential for ensuring nutraceutical safety and sustainability. Green chemistry emphasizes minimizing the use of hazardous substances and reducing waste generation, objectives that align closely with regulatory imperatives for public health and environmental protection. In nutraceutical formulation, substituting hazardous excipients or solvents with safer alternatives can enhance product safety in accordance with EFSA’s botanical safety assessment guidelines. While regulatory agencies are increasingly integrating green chemistry considerations into their evaluation processes, the lack of a universally accepted definition for “nutraceutical” complicates compliance efforts, blurring the boundaries between food and pharmaceuticals and potentially hindering the systematic application of sustainable chemistry principles in the sector.

Cross-Sector Collaboration: Academia–Industry–Government to Mainstream GAC:

Mainstreaming Global Action for Climate (GAC) within analytical science and the nutraceutical sector demands coordinated engagement across academia, industry, and government. Cross-sector collaboration, an emerging paradigm in new public governance, prioritizes cooperative, multi-stakeholder partnerships over isolated, sector-specific initiatives. This integrative approach is critical for addressing complex, interlinked challenges, including those arising from climate change, that exceed the capacity of any single sector to resolve independently. Governments alone often face limitations in resources, technical expertise, and policy agility, necessitating the involvement of private-sector innovation and non-governmental expertise⁷⁵. Lessons from coordinated responses to cybersecurity threats underscore the value of multi-actor partnerships in building systemic resilience, an approach equally applicable to GAC strategies⁷⁶. By combining infrastructure, knowledge, and funding streams, academia, industry, and government collaborations can more effectively design and implement sustainable analytical methodologies while addressing broader societal and environmental objectives.

CONCLUSION:

The evolution of nutraceutical analysis is increasingly shaped by the convergence of green chemistry principles, innovative analytical technologies, and sustainability-driven regulatory frameworks. The shift from conventional, solvent-intensive techniques toward environmentally benign methodologies, such as green extraction strategies, sustainable spectroscopy, solvent recycling, and AI-assisted method optimization, reflects a global imperative to balance analytical performance with environmental stewardship.

Emerging trends such as paper-based microfluidic devices, lab-on-a-chip systems, and sensor-based analytical platforms are enabling miniaturization, solvent-free operation, and real-time monitoring, significantly reducing waste generation while enhancing process efficiency. Coupling these advances with chemometric modeling, digital twins, and blockchain-enabled traceability systems ensures analytical integrity from raw material sourcing to consumer verification, thereby strengthening supply chain transparency and consumer trust.

The nutraceutical sector’s increasing embrace of circular economy concepts, through solvent recycling, valorization of plant residues, and adoption of modular, energy-efficient laboratory systems, further underscores the sector’s role in advancing sustainable innovation. However, widespread implementation remains challenged by scalability barriers, regulatory standardization gaps, and the need for harmonized definitions and evaluation metrics.

Cross-sector collaboration among academia, industry, and government, aligned with international frameworks such as ISO, EFSA, FDA, and FSSAI guidelines, will be essential for mainstreaming Green Analytical Chemistry (GAC) practices. As the sector moves “beyond chromatograms,” the integration of precision analytics, environmental responsibility, and regulatory compliance will define the next frontier in nutraceutical science, ensuring that innovation not only drives market growth but also preserves ecological balance and public health.
