Long-chain polyunsaturated fatty acids (LC-PUFAs) of omega-3 family, particularly docosahexaenoic acid and eicosapentaenoic acid, are essential nutrients that play a critical role in children’s growth and health. This review examines the evidence on the effects of omega-3 supplements and omega-3-enhanced foods on children’s development, as well as on neurological and metabolic disorders. Research consistently highlights the importance of DHA in brain and visual development, especially during early childhood, when rapid neural growth occurs. PubMed, Web of Science, Scopus and the Cochrane Library databases were searched for relevant articles published up to January 2026. Adequate omega-3 intake has been associated with improvements in cognitive performance, attention, and learning outcomes. In children with neurodevelopmental conditions such as attention-deficit/hyperactivity disorder and autism spectrum disorder, omega-3 supplementation shows modest but potential benefits in reducing behavioral symptoms and supporting executive function, although results remain mixed. Additionally, omega-3 fatty acids exhibit anti-inflammatory properties that may positively influence metabolic health, including lipid profiles, insulin sensitivity, and obesity-related risk factors in children. Omega-3-enhanced foods provide an alternative to supplements and may improve adherence and overall dietary quality. However, variability in dosage, study design, and baseline nutritional status limits definitive conclusions. Overall, omega-3 fatty acids appear to support healthy development and may aid in managing certain neurological and metabolic disorders in children. Full article

Background: The first 1000 days of life, from conception to 2 years of age, represent a critical window during which nutrition can exert long-lasting effects on neurodevelopment, immune maturation, and susceptibility to prematurity-related morbidity. Docosahexaenoic acid (DHA) is a key structural n-3 long-chain polyunsaturated fatty acid of the brain and retina, characterized by rapid fetal accretion during the third trimester. Methods: We conducted a narrative review of studies published from March 2015 up to December 2025, including randomized controlled trials, follow-up studies, and systematic reviews/meta-analyses about DHA supplementation during pregnancy, lactation, infancy and early childhood, and its role on development. Results: Across the first 1000 days, DHA supplementation improves biochemical DHA status, particularly in populations with low baseline levels (moderate to high level of evidence), while clinical outcomes remain heterogeneous. During pregnancy, some benefits in specific cognitive and behavioral domains have been demonstrated, whereas effects on global cognition and long-term behavior are frequently null (moderate evidence). Visual outcomes appear favorable, with improvements in visual acuity (moderate evidence). In preterm infants, enteral DHA—often combined with arachidonic acid (ARA)—is feasible and well tolerated. DHA may reduce inflammatory markers and necrotizing enterocolitis risk when in equilibrium with ARA (low to moderate evidence), while no evidence supports the link between DHA and reduced risk of bronchopulmonary dysplasia and retinopathy of prematurity (moderate evidence). Neurodevelopmental outcomes are mixed: neuroimaging studies suggest enhanced white matter maturation with DHA + ARA, whereas most trials show no clear benefit regarding standardized developmental scores (moderate evidence). Conclusions: DHA is biologically essential during the first 1000 days, but its clinical impact depends on timing, dose, baseline status, and prematurity-related context. The balance between DHA and ARA, rather than DHA supplementation alone, emerges as a key determinant of clinical efficacy, supporting a shift toward precision-based nutritional strategies in early life.

Maternal nutrition during pregnancy plays a crucial role in fetal development and metabolic programming. Long-chain omega-3 polyunsaturated fatty acids (LC-PUFA n-3), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are known to influence mitochondrial function and cellular energy metabolism. The present preliminary study aimed to evaluate the effects of maternal omega-3 supplementation on mitochondrial bioenergetics in neonatal piglets. Pregnant sows were supplemented with either fish oil or algal oil rich in LC-PUFA n-3 (long-chain omega-3 polyunsaturated fatty acids) throughout gestation. Liver samples were collected from newborn piglets immediately after birth, and mitochondrial respiratory parameters, oxygen consumption rates, and selected oxidative stress markers were analyzed. The results indicated that maternal omega-3 supplementation was associated with improved mitochondrial respiratory parameters and enhanced oxidative phosphorylation efficiency in neonatal liver tissue. Both fish oil and algal oil supplementation showed similar trends in improving mitochondrial bioenergetic function. Although the study was exploratory and conducted on a limited number of animals, the findings suggest that maternal intake of LC-PUFA n-3 may influence mitochondrial metabolism in offspring. Further studies with larger experimental groups are required to confirm these observations and to better understand the mechanisms underlying these effects. Full article

The spotted scat (Scatophagus argus) is a fish species widely distributed in Indo-Pacific waters. In China, females are preferred for aquaculture due to their faster growth rates. Reproduction in teleost fish requires substantial energy, primarily in the form of lipids and fatty acids, which are closely linked to reproductive success and ovarian development. In this study, female spotted scat broodstock were sampled bi-monthly from May 2019 to March 2020 to examine annual ovarian development, lipid droplet accumulation, and fatty acid composition in the liver and ovaries. Body weight, total length, standard length, and condition factor (CF) increased gradually over the sampling period. In July 2019, the gonadosomatic index (GSI) increased significantly, all ovaries reached stage IV, and lipid droplet accumulation was most pronounced. Ovarian saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), n-3 polyunsaturated fatty acids (n-3 PUFA), and n-6 PUFA reached their highest levels in July, whereas the ovarian n-3 PUFA/n-6 PUFA ratio was highest in May. The hepatosomatic index (HSI) was significantly higher from November to March than from May to September. The viscerosomatic index (VSI) was significantly elevated from November to March and in July. Liver lipid droplet accumulation was lowest from May to July. Absolute contents of liver SFA, MUFA, and n-6 PUFA were significantly higher in January and March than in May and July, while liver n-3 PUFA content and the n-3 PUFA/n-6 PUFA ratio peaked in May. These findings indicate that the peak breeding season of spotted scat occurs around July in southern China. From winter to spring, lipids accumulate in the abdominal cavity and liver, likely serving as energy reserves for subsequent ovarian development. The liver appears to play a key role in the uptake and transfer of n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) to the ovaries prior. This study provides useful insights into the reproductive physiology of spotted scat and supports improved broodstock management in aquaculture. Full article

A novel optimized bioactive lipid (OBL) rich in long-chain polyunsaturated omega-3 fatty acids (n-3 LCPUFA) was synthesized through enzymatic acidolysis using concentrated belly oil from rainbow trout (Oncorhynchus mykiss) (CB) and tocopherols obtained from cold-pressed maqui seed oil (Aristotelia chilensis (Mol.) Stuntz) (MSO) under supercritical CO₂ conditions. The reaction was catalyzed by Candida antarctica lipase B (CALB) and optimized using a 3² response surface design with 12 experimental runs and three central points, considering pressure (100–300 bar) and temperature (50–80 °C) as independent variables. The response variables included the concentrations of EPA, DHA, α-, β-, γ-, and δ-tocopherols, as well as β- and γ-tocotrienols. MSO contained 10.63, 25.62, and 53.55 g·100 g⁻¹ total fatty acids (TFAs) of α-linolenic, oleic, and linoleic acids, respectively, together with 280.95 mg α-tocopherol·kg⁻¹ and 89.75 mg β-tocotrienol·kg⁻¹. The CB contained 49.57 g EPA + DHA·100 g⁻¹ TFAs. Optimal conditions (72.7 °C and 248.9 bar), experimentally validated at the RSM-predicted point, yielded an OBL containing 41.28 g EPA + DHA·100 g⁻¹ TFAs, 0.39 mg α-tocopherol·kg⁻¹, 3.54 mg β-tocopherol·kg⁻¹, 18.48 mg β-tocotrienol·kg⁻¹, 6.92 mg γ-tocopherol·kg⁻¹, and 16.36 mg γ-tocotrienol·kg⁻¹. Oil quality evaluation using official AOCS methods showed that the OBL exhibited an acceptable oxidative status within international regulatory limits while retaining a measurable phenolic content and intermediate antioxidant capacity derived from MSO. This study demonstrates the successful synthesis of a stable OBL from agro-industrial by-products as a sustainable source of functional ingredients for food, nutraceutical, and cosmetic applications.

Background: Consumption of fruits of different origins with specific (poly)phenolic profiles can modulate the gene expression of enzymes and the levels of metabolites in a photoperiod-dependent manner. However, there is little information on how this affects the profile of hepatic and muscular fatty acids (FAs) and how it interferes with metabolic pathways. This study aimed to determine whether consuming local or non-local cherries alters liver and muscle FA profiles under different photoperiods, and to identify the associated changes in metabolic gene expression and serum metabolites. Methods: Seventy-two Fischer 344 rats, fed a standard diet and either vehicle (VH), Local Cherry (LC), or non-Local Cherry (nLC), were exposed to different hours of light to simulate photoperiods (winter, spring/autumn, or summer) for 7 weeks. The FA profiles of the liver and muscle were determined using GC-FID, and the gene expression of key enzymes involved in FA metabolism was evaluated. Moreover, the composition of hydrophilic and lipophilic metabolites in the serum and liver was analyzed using nuclear magnetic resonance (NMR), and pathway analysis was performed. Results: Consumption of cherries in season (18 h of light) decreased saturated FAs levels in the liver, mainly palmitate, compared to their respective VH; interestingly, this effect was not observed in other photoperiods. Furthermore, muscle polyunsaturated FA (PUFAs) decreased, possibly due to increased oxidation. Conclusions: Seasonal cherry consumption improves the hepatic lipid profile and increases muscular oxidation. Future studies are needed to better define these effects and uncover the differences in lipid metabolism in response to cherry consumption. Full article

The global demand for fish oil (FO) is increasing while its supply is decreasing, which has limited its use in aquafeeds. Research on alternative terrestrial oils (TOs) for commonly cultured fish species in Bangladesh is limited. This research involved a 70-day feeding experiment to assess the effectiveness of replacing FO with TOs in the diet of Gangetic catfish (Mystus cavasius). Five diets were formulated: a control diet (D1) with fish meal and FO, and four diets replacing FO with soybean oil (D2), black soldier fly larvae oil (D3), palm oil (D4), or a mixed oil combination (D5) of 50% black soldier fly larvae oil, 25% soybean oil, and 25% palm oil. A total of 675 fish (0.5 g each) were distributed in 15 100 L aquariums (45 fish/aquarium) and fed to satiation twice daily. Fish fed with Diet D5 showed significantly higher growth, followed by those fed with D3, D4, and D1, while D2 resulted in significantly lower growth. Fish on the D5 diet consumed the most feed, followed by those on the D3 and D2 diets, with similar feed intake levels for those on the D1 and D4 diets. FCR, FCE, and PER were not significantly affected by dietary oil sources. Whole-body lipid content (p < 0.05) was significantly lower in the D3 group and higher in the D2 group, while other groups showed intermediate values. The fatty acid composition in the fish reflected their diets: significantly higher n-3 LC-PUFA (EPA + DHA) content was observed in the D1 group, followed by the D4 and D3 groups, and fish fed with D2 and D5 showed significantly lower values. Alpha-linolenic acid C18:3n-3) was significantly higher in the D2 group, followed by the D3, D1, and D4 groups, with the D5 group having a significantly lower value. Total MUFA was significantly higher in D4, followed by D1, D5, and D3; the D2-fed group showed a significantly lower value. Lauric acid (C12:0) was significantly higher in D3, followed by D5; other groups showed significantly lower values. Feed physical properties were significantly influenced by oil type, with water stability, pellet durability, and palatability being significantly highest in the D2 and D5 diets, followed by D3 and D4, with D1 being the lowest. Fish on the D1 and D5 diets had a significantly higher condition factor (CF) compared to fish on the D2 diet. Considering the growth and overall performance in the current study, we concluded that under the current dietary composition, TOs can effectively replace FO in the diets of Gangetic catfish, with mixed oils, black soldier fly larvae oil, and palm oil being the most promising alternatives.

Background/Objectives: Watermelon (Citrullus lanatus) processing generates substantial quantities of rind, seeds, and residual pulp that are typically discarded despite being rich in polyunsaturated fatty acids, polar lipids, carotenoids, and phenolic compounds. These amphiphilic bioactives are increasingly recognized for their roles in modulating oxidative stress, inflammation, and platelet activation; however, the lipid fraction of watermelon by-products remains insufficiently characterized. This study examined organic watermelon juice and its by-products to isolate, characterize, and evaluate extracts enriched in amphiphilic and lipophilic bioactives, with emphasis on their in vitro antioxidant, anti-inflammatory, and antithrombotic properties. Methods: total lipids were extracted using a modified Bligh–Dyer method and fractionated into total amphiphilic compounds (TAC) and total lipophilic compounds (TLC) via counter-current distribution. Phenolic and carotenoid levels were quantified, and antioxidant capacity was assessed using DPPH, ABTS, and FRAP assays. Anti-platelet and anti-inflammatory activities were evaluated against ADP- and PAF-induced platelet aggregation. Structural characterization of polar lipids was performed using ATR–FTIR, and LC–MS was used to determine fatty acid composition and phospholipid structures. Results and Discussion: Carotenoids were primarily concentrated in the TLC fractions with high ABTS values for antioxidant activity, while phenolics mostly in the juice, the TACs of which showed the strongest total antioxidant capacity based on DPPH. TAC fractions of both samples showed also higher FRAP values of antioxidant activity, likely due to greater phenolic content. TAC extracts also exhibited notable inhibition of PAF- and ADP-induced platelet aggregation, associated with their enriched ω-3 PUFA profiles and favorable ω-6/ω-3 ratios based on their LC-MS profiles. Conclusions: Overall, watermelon products (juice) and by-products represent a valuable and sustainable source of amphiphilic bioactives with significant antioxidant, anti-inflammatory, and anti-platelet potential, supporting their future use in functional foods, nutraceuticals, and cosmetic applications.

Purpose: To investigate associations between lipid oxidation biomarkers (oxylipins), antioxidant micronutrients, lipoprotein particles, and apolipoproteins in multiple sclerosis (MS). Methods: Blood and neurological assessments were collected from 30 healthy controls, 68 relapsing remitting MS subjects, and 37 progressive MS subjects. Hydroxy (H) and hydroperoxy lipid peroxidation products of the polyunsaturated fatty acids (PUFAs) arachidonic (20:4, ω-6), linoleic (octadecadienoic acid or ODE, 18:2, ω-6), eicosapentaenoic (20:5, ω-3), and α-linolenic (18:3, ω-3) acids were measured using liquid chromatography–mass spectrometry. Antioxidant micronutrients, including β-cryptoxanthin and lutein/zeaxanthin, were quantified by high-performance liquid chromatography. Lipoprotein and metabolite profiles were obtained using nuclear magnetic resonance spectroscopy. Regression models were adjusted for age, sex, body mass index, and disease status. Results: The 9-hydroxy octadecadienoic acid to 13-hydroxy octadecadienoic acid ratio (9-HODE/13-HODE ratio), which reflects autoxidative versus enzymatic oxidation, was associated with MS status (p = 0.002) and disability on the Expanded Disability Status Scale (p = 0.004). Lutein/zeaxanthin (p = 0.023) and β-cryptoxanthin (p = 0.028) were negatively associated with the 9-HODE/13-HODE ratio. Apolipoprotein-CII, a marker of liver-X-receptor (LXR) signaling, was associated with 9-HODE/13-HODE ratio and other oxylipins. Octadecadienoic fatty acid-derived oxylipins were negatively associated with LC3A, a mitophagy marker, and positively correlated with 7-ketocholesterol, a cholesterol autoxidation product. Conclusions: Autoxidation of PUFAs is associated with greater disability in MS. Higher β-cryptoxanthin and lutein/zeaxanthin were associated with reduced auto-oxidation. Lipid peroxidation shows associations with LXR signaling, mitophagy, inflammation, and cholesterol autoxidation. Full article

Background: Atherosclerosis and its associated chronic inflammation of the arterial wall disrupt fatty acid metabolism, leading to changes in plasma fatty acid composition. These alterations can be used to improve disease diagnosis and risk stratification by the development and application of specific lipidomic indices. Objectives: The objectives of this study are to evaluate the performance of conventional fatty acid indices and enhance diagnostic efficiency in atherosclerosis by introducing novel index based on plasma PUFA n-6 and n-3 content (Omega-6/3 Balance Index, O6/3-BI), as well as the perspective SFA/MUFA ratio (stearic/oleic acid ratio, C18:0/C18:1n-9) and a logit function combining PUFA and SFA/MUFA biomarkers. Methods: Plasma fatty acids were quantified by LC-MS/MS in healthy controls (n = 50) and patients with carotid atherosclerosis (n = 52), stratified by atorvastatin, rosuvastatin, or no statin therapy. The conventional indices (the Omega-3 Status (EPA + DHA), AA/EPA, and the omega-6/omega-3 ratio), and pathway ratios (C18:0/C18:1n-9; and C20:4n-6/C22:4n-6), as well as the newly introduced PUFA index and combined PUFA-SFA/MUFA logit function, were calculated. Their diagnostic performance for distinguishing atherosclerosis was assessed by a receiver operating characteristic (ROC) analysis with the cross-validation and calculation of Cliff’s Δ effect size. Results: The conventional parameters demonstrated a poor to low discrimination ability of the atherosclerosis patients’ groups from healthy controls (area under the ROC curve, AUC 0.548–0.711). In statin-treated patients, these conventional markers lost significance. The newly introduced PUFA index and SFA/MUFA ratio demonstrated improved patients’ discrimination with AUC 0.734–0.780 for the former and strong predictive power with AUC 0.831–0.858 for the latter marker and maintained their diagnostic value under statin therapy. The most significant positive effect size was observed for the SFA/MUFA ratio with Cliff’s Δ = 0.67–0.71. The combined PUFA-SFA/MUFA logit function also demonstrated a strong predictive power with AUC = 0.880 (Cliff’s Δ = −0.76), outperforming any single index. Conclusions: The newly introduced lipidomic index based on the PUFA content, SFA/MUFA ratio, and a logit function combining PUFA-SFA/MUFA biomarkers demonstrated a substantially better discrimination of atherosclerosis-related fatty acid metabolic disturbances than conventional fatty acid biomarkers.

Maternal undernutrition remains a major modifiable risk factor for adverse pregnancy outcomes. Dietary supplements are widely used to bridge nutritional gaps, but their efficacy, safety, and quality control remain controversial. This review critically evaluates the mechanisms, clinical evidence, and quality assurance of key supplements (folic acid, iron, vitamin D, calcium, iodine, omega-3 PUFA, choline, and multiple micronutrients) specifically in pregnant and postpartum women. We highlight that while folic acid (400–800 µg/d) and iron supplementation reduce neural tube defects by >70% and maternal anaemia by 30–50%, respectively, high-dose antioxidant cocktails (vitamins C + E) have shown no benefit and potential harm in large RCTs. Up to 18–40% of commercially available prenatal supplements contain undeclared pharmaceuticals, heavy metals, or incorrect dosages, underscoring the urgent need for advanced analytical methods (LC-MS/MS, HRMS, NMR). We propose the GAPSS (Genotype–Analytics–Physiology–Safety–Sustainability) framework for future personalised maternal nutrition. Rigorous, pregnancy-specific quality control combined with biomarker-guided supplementation is essential to maximise benefits and minimise risks. Full article

Obesity, type 2 diabetes (T2D), and insulin resistance are pervasive metabolic disorders marked by chronic low-grade inflammation and systemic metabolic disorders. The emerging field of immunometabolism highlights how interactions between immune processes and metabolic pathways in adipose tissue, liver, muscle, and pancreatic islets contribute to disease pathogenesis. Lipid dysregulation plays a central role in these processes, with distinct lipid molecules identified in obese patients as compared to lean patients that correlate with insulin resistance, inflammation, and vascular dysfunction. This Special Issue compiles a multidisciplinary body of research aimed at elucidating molecular mechanisms, identifying novel biomarkers, and exploring innovative therapeutic strategies. Key contributions include studies on omega-3 long-chain polyunsaturated fatty acids (LCPUFAs) and their differential associations with neurocognitive development; the potential of beta-defensin 2 as a biomarker linking gut-derived inflammation and metabolic dysfunction; and the promotion of adipocyte browning by Carnosic acid via AMPK activation and GSK3β inhibition. Additionally, reviews of phytochemicals underscore their multisystem therapeutic potential, while investigations into sodium–glucose cotransporter-2 (SGLT2) inhibitors suggest possible metabolic and neuroprotective benefits beyond glucose control. Maternal lipid metabolism during pregnancy and its impact on maternal fetal health further emphasize the clinical complexity of lipid dysregulation. Despite promising insights, significant gaps remain regarding causality versus correlation in lipid biomarkers, standardization of analytical methodologies, tissue heterogeneity, and unintended effects of metabolic interventions. Collectively, these studies underscore the necessity of integrative, mechanism-driven research to bridge fundamental biology with translational and clinical applications, ultimately advancing precision therapies for metabolic diseases.

Echium species, abundant in the Canary Islands, contain unique fatty acids (FA) such as stearidonic acid (SDA; 18:4n-3) and γ-linolenic acid (GLA; 18:3n-6), which may improve egg quality while valorizing local genetic resources. This study evaluated the effects of Echium plantaegineum oil (EO) compared with linseed oil (LO) and soybean oil (SO) on productive performance, egg quality, sensory traits, and yolk fatty acid profile. Forty-eight hens from the Canary Islands were fed for 31 days with diets supplemented with 1.25% SO (SO-d), 1.1% LO + 0.15% beef tallow (LO-d), and 1% EO + 0.25% LO (EO-d). LO supplementation reduced laying rate and egg mass with respect to SO, increasing feed conversion ratio (FCR), whereas EO produced slightly lighter eggs compared to the SO group but with normal yolk proportion and shell traits. EO markedly increased egg yolk deposition of SDA, eicosapentaenoic acid (EPA; 20:5n-3), docosapentaenoic acid (n-3 DPA; 22:5n-3), and docosahexaenoic acid (DHA; 22:6n-3), while lowering the n-6/n-3 ratio and thrombogenic index (TI). No differences were observed in the evaluated sensory attributes among treatments. In conclusion, dietary inclusion of EO effectively enriches eggs with n-3 LC-PUFA without negatively affecting sensory quality, supporting its potential use as a functional ingredient in laying hen diets.

Resveratrol (RES), a natural polyphenol, and β-hydroxy-β-methylbutyric acid (HMB), a key metabolite of leucine, are emerging as potent feed additives in animal production. This study investigated the individual and combined effects of dietary RES and HMB on gut microbiota, metabolic profiles, and meat quality in Tibetan sheep. A total of 120 two-month-old male lambs were randomly assigned to four experimental groups: control (C, basal diet, n = 6), RES (basal diet + 1.5 g/d RES, n = 6), HMB (basal diet + 1.25 g/d HMB, n = 6), and RES-HMB (basal diet + 1.5 g/d RES + 1.25 g/d HMB, n = 6), with 16S rDNA sequencing and LC-MS/MS analyses performed on rumen fluid and longissimus lumborum (LL). Meat quality improved significantly in all supplemented groups, the RES-HMB co-administration exhibited the most pronounced effects, suggesting a synergistic interaction. These improvements were linked to the activation of amino acid (AA) and unsaturated fatty acid biosynthesis pathways, leading to increased levels of AAs and polyunsaturated fatty acids (PUFAs). Concurrently, dietary RES and HMB supplementation enriched the relative abundance of beneficial gut microbiota, notably Christensenellaceae_R-7_group and Solibacillus, which further promoted the production of short-chain fatty acids, AAs, and PUFAs. The study highlights the role of rumen microbiota in regulating muscle metabolism and meat quality, offering a new scientific basis of strategies for using green feed additives in Tibetan sheep.

Carotenoids and microbial lipids are valuable bioactive compounds with potent antioxidant and anti-inflammatory properties. Microbial biosynthesis provides a sustainable alternative to conventional plant extraction and chemical synthesis. Here, we report the isolation and characterization of a novel oleaginous yeast, Rhodotorula evergladensis CXCN-6, from the surface of Nymphaea ‘Gorgeous Purple’. The strain displayed intense reddish-orange pigmentation due to intracellular carotenoid accumulation. HPLC and LC–MS analyses identified torularhodin as the predominant carotenoid (m/z 563.4 [M]⁺), while lipids were rich in linoleic (C18:2), oleic (C18:1), and α-linolenic (C18:3) acids. Under optimized fermentation, CXCN-6 yielded 63.56 mg/L torularhodin and 9.83 g/L total lipids. The CXCN-6 extract showed strong DPPH and ABTS radical scavenging activities and significantly reduced intracellular ROS levels in UVA (9 J/cm²)-stimulated HaCaT cells. It also suppressed IL-6 and TNF-α secretion in LPS-activated macrophages without cytotoxicity. Collectively, these results establish R. evergladensis CXCN-6 as a novel and efficient microbial platform for the co-production of torularhodin and PUFA-rich lipids with potent antioxidant and anti-inflammatory properties, offering promising applications in nutraceutical, skincare, and functional food industries.
