I. Introduction
Ascophyllum nodosum is a brown seaweed that has gained increasing attention as a functional ingredient in animal nutrition due to its diverse range of biologically active compounds and associated health-promoting properties. Over the past decade, numerous studies have investigated its effects in both companion animals and experimental models, demonstrating activities that extend beyond oral health to include antioxidant, anti-inflammatory, antimicrobial, immunomodulatory, prebiotic, antidiabetic, and anticancer effects. Owing to this broad spectrum of biological activities, A. nodosum has emerged as a promising nutraceutical with potential applications in veterinary medicine and animal health. This review summarizes the current evidence regarding its bioactive composition and the mechanisms underlying its reported health benefits, with particular emphasis on its relevance to companion animals.
II. Periodontal Disease in Companion Animals
More than two-thirds of dogs and cats reach the age of two suffering from periodontal disease, a prevalence that grows as these animals get older. Managing dental plaque remains the primary strategy for both treatment and prevention. Research indicates that bacterial plaque is the leading driver of periodontal issues. While tartar on the teeth is not a disease in itself, it serves as a marker of poor oral hygiene, representing the final stage of mineralized plaque accumulation. Furthermore, tartar facilitates additional plaque buildup and can lead to mechanical irritation, which may cause ulcers on the mucous membranes. Even after following a properly performed dental cleaning procedure, salivary glycoproteins begin accumulating on the tooth surface within a few hours. These glycoproteins form a thin coating known as the pellicle, which is rapidly colonized by oral bacteria over the next several hours. As a result, bacterial dental plaque can start forming on freshly cleaned teeth as early as the day after the procedure.
In addition to bacteria, the developing plaque contains food debris, shed oral epithelial cells, and other microorganisms. Initially, "immature" dental plaque exists as a thin coating on the teeth. If this deposit is not removed, it adheres more firmly to the tooth enamel and develops a more complex, organized structure, eventually maturing into a biofilm composed of colonies of bacteria and protozoa. The outer surface of the biofilm is predominantly populated by aerobic bacteria, whereas the deeper layers adjacent to the tooth surface provide a favorable environment for anaerobic bacteria. Once plaque reaches maturity it begins to undergo gradual mineralization if left undisturbed. Over the next two days, this mineralized plaque develops into dental calculus (tartar). Although calculus itself is not inherently pathogenic, it creates a surface that facilitates the accumulation and persistence of microorganisms associated with the development of periodontal disease. The pathogenic microorganisms within dental plaque release toxins that trigger inflammation of the gingival tissues, leading to gingivitis. If this condition is not adequately managed, it can progress to periodontitis, an irreversible stage of periodontal disease characterized by the destruction of the periodontal ligament, resorption of the alveolar bone, and degeneration of the gingiva and cementum supporting the teeth [1].
To prevent periodontal disease, strategies must focus on managing the development of plaque and calculus. Home care routines generally fall into two categories: active and passive. Of the active methods, daily tooth brushing is considered the gold standard, as it can decrease plaque by 37.4% and calculus by 80.2% when compared to dogs that do not receive routine brushing [2]. Additional active approaches to home oral care include the use of oral cleansing gels and barrier sealants, which can help support plaque control and maintain oral hygiene [3, 4]. In addition to these measures, a variety of passive oral care strategies have been developed, such as specialized diets, dental treats, chews, water additives, and nutritional supplements. The efficacy of these passive methods is largely attributed to their mechanical action, chemical activity, or a combination of both mechanisms in reducing plaque and calculus accumulation [5].
III. Ascophyllum nodosum and Its Bioactive Components
The brown seaweed Ascophyllum nodosum has attracted considerable attention as a dietary ingredient for passive oral health management in companion animals. The beneficial effects of Ascophyllum nodosum have been attributed to its potential ability to enhance oral immune responses and alter salivary composition, thereby supporting overall oral health [6,7]. Ascophyllum nodosum is a prominent brown seaweed belonging to the family Fucaceae and is widely distributed along the coastal regions of France, Ireland, Norway, northern Canada, Europe, and the United States [9] . Commonly known by names such as knotted wrack, knotted kelp, Norwegian kelp, sea kelp, egg wrack, and rockweed, this species typically inhabits the mid-intertidal zone of saline coastal environments. Its growth in these salt-rich habitats contributes to its characteristic salty flavor [10].Ascophyllum nodosum extract (ANE) is a subject of significant pharmacological interest because of its efficiency in sequestering and concentrating a wide range of minerals, nutrients, and bioactive compounds from the marine environment [11].
Recent investigations have revealed that Ascophyllum nodosum extract (ANE) is a rich source of numerous biologically active substances, including proteins, lipids, carbohydrates, enzymes, flavonoids, polyphenolic compounds, vitamins, minerals, and trace elements [14]. Among its major constituents are complex polysaccharides such as fucoidans, alginates, and laminaran [15], together with phlorotannins, a distinctive group of marine-derived secondary metabolites [16]. These compounds are believed to be largely responsible for the diverse health-promoting properties attributed to A. nodosum, which include modulation of inflammatory responses and support of beneficial gut microbiota through prebiotic activity [17, 18, 19]. Ascophyllum nodosum is composed of approximately 45% to 60% polysaccharidesmost notably alginate, mannitol, and fucoidansalong with 8% to 14% water, 5% to 8% protein, and 2% to 4% fat, in addition to a variety of essential minerals and vitamins [8].
Ascophyllum nodosum extract boasts a highly diverse profile of bioactive compounds. Its carbohydrate content includes fucoidan, alginate, laminarin, ascophyllan, mannitol, fucoxanthin, and maltodextrin, while its protein profile features crude proteins and essential digestive enzymes like amylase, lipase, protease, and bromo-peroxidase. The extract also provides a range of polyphenols, such as pyrogallol, phloroglucinol sulfate, and phlorotannins (which are polymers of phloroglucinol), alongside a complex array of flavonoids like quercetin, dihydroquercetin, datiscin, diosmin, homoorientin, acacetin, apigenin-7-O-glucoside, kaempferol-3,7-O-bis alpha-l-rhamnoside, and 2′1, B 6′-dihydroxy-4-methoxychalcone-4′-O-neohesperidoside. Furthermore, it is a rich source of vitamins, including A, C, D, E, K, and the full spectrum of B vitamins specifically B2, B3, B5, B6, B7 (biotin), B9 (folic acid), and B12. Beyond these, the alga contains a broad spectrum of minerals and trace metals, including calcium, sodium, potassium, magnesium, phosphorus, iodine, zinc, boron, manganese, chlorine, sulfur, barium, copper, iron, vanadium, nickel, cobalt, molybdenum, and trace quantities of lead, cadmium, mercury, and tin, complemented by other components such as polyunsaturated fatty acids, folinic acid, carotene, and ash.
The diverse bioactive compounds present in Ascophyllum nodosum have been linked to a wide range of biological and therapeutic activities. Studies have reported that these constituents exhibit antioxidant, anticancer, neuroprotective, antidiabetic, antibacterial, anti-inflammatory, immunomodulatory, and anti-periodontal effects. Owing to these functional properties, A. nodosum and its extracts have been increasingly explored for applications in metabolic syndrome management and as ingredients in nutritional supplements [11, 12, 13].
IV. Benefits of Ascophyllum nodosum in Companion Animals
Oral Health-Promoting Effects
In a study investigating the systemic impact of Ascophyllum nodosum supplementation in dogs, notable alterations in the salivary metabolomic profile were observed after 30 days of treatment when compared with placebo-treated controls. The detection of isofucosterol, an algal-specific sterol, in saliva provided evidence that bioactive compounds derived from the seaweed were absorbed and distributed systemically. Furthermore, supplementation was associated with modifications in multiple metabolic pathways, including enhanced selenoamino acid metabolism and changes in pathways related to prostaglandins, androgens, and estrogens, suggesting broader physiological effects beyond the oral cavity. A particularly noteworthy finding was the absence of several metabolites involved in prostaglandin synthesis and related biochemical pathways following A. nodosum supplementation. This observation suggests that the seaweed may interfere with biological processes associated with the formation of dental plaque and calculus. Collectively, these results provide evidence that Ascophyllum nodosum may promote oral health through systemic mechanisms; however, the exact pathways responsible for these effects have yet to be fully elucidated and warrant further research [7]. In a placebo-controlled, double-blind, randomized study of 60 client-owned dogs representing breeds such as the Chihuahua, Japanese Chin, Miniature Schnauzer, Pomeranian, and West Highland White Terrier, researchers examined the oral health effects of Ascophyllum nodosum-enriched edible treats over a 90-day period. To ensure a standardized baseline, every participant underwent professional dental cleaning under general anesthesia before being assigned to receive either a weight-adjusted dose of the algal supplement or a placebo. Clinical examinations carried out under sedation at 30-day intervals revealed that dogs receiving Ascophyllum nodosum experienced markedly better oral health outcomes than those in the placebo group. Over the 90-day study period, supplementation was associated with lower levels of dental plaque, calculus deposition, and volatile sulfur compounds, while measures of gingival health and overall oral condition showed noticeable improvement. The results demonstrated that regular intake of A. nodosum-containing treats effectively limited the buildup of plaque and tartar and contributed to better oral health in the treated dogs [6].
A six-week investigation in dogs and cats demonstrated that supplementation with a formulation containing Ascophyllum nodosum had a beneficial effect on oral health. Animals receiving the supplement experienced a substantially slower decline in oral condition, with the rate of deterioration being roughly 50% lower than that observed in animals that received no oral hygiene intervention. This improvement was evidenced by decreased accumulation of dental plaque and calculus, together with enhanced periodontal health and improved mandibular lymph node status. These results indicate that A. nodosum supplementation may help delay the progression of oral disease and serve as a useful adjunct for maintaining oral hygiene in companion animals [1].
In a randomized, controlled cross-over trial with 61 adult subjects, researchers assessed the efficacy of daily 500 mg Ascophyllum nodosum (ProDen PlaqueOff®) supplementation over two distinct six-month intervals. Participants continued their standard oral hygiene routines throughout the study, preceded by professional dental cleanings at the start of each phase. Among the 55 individuals who finished the trial, those taking the algal supplement exhibited a 52% average decrease in supragingival calculus accumulation compared to the placebo group. Furthermore, the treatment group showed statistically significant reductions in plaque levels and gingival bleeding, though no significant impact on gingivitis was recorded. The study concluded that A. nodosum provides systemic oral health benefits, additionally noting that the calculus that did form in the treatment group was notably more porous and simpler to remove than in the control group [20].
Antimicrobial Effects
Ascophyllum nodosum has demonstrated antimicrobial activity against a variety of pathogenic microorganisms while also supporting the growth of beneficial bacteria. Evidence from in vitro studies suggests that its bioactive compounds may help modulate microbial populations and contribute to improved gut and overall health.
The antimicrobial potential of a polyphenol-enriched extract derived from Ascophyllum nodosum was investigated following extraction by a microwave-assisted technique. The extract exhibited inhibitory effects against a range of pathogenic and food-associated bacteria, including Bacillus cereus, Salmonella enteritidis, Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis, although no activity was detected against Escherichia coli. Among the tested microorganisms, Staphylococcus aureus was the most susceptible to the extract. The results indicate that the polyphenol-rich constituents of A. nodosum possess notable antibacterial activity, supporting the potential use of this seaweed as a natural source of antimicrobial compounds [28]. The antibacterial and prebiotic effects of Ascophyllum nodosum were examined in an in vitro study comparing whole seaweed biomass with extracts obtained through different extraction techniques. Using a fermentation model based on fecal samples from weaned pigs, researchers found that A. nodosum altered the composition of the microbial community, with certain preparations decreasing populations of Enterobacteriaceae while simultaneously supporting overall bacterial growth. Additional testing with individual bacterial cultures revealed that the biological effects varied according to the type of extract produced. Some extracts suppressed the growth of pathogenic microorganisms, including Salmonella Typhimurium and enterotoxigenic Escherichia coli, whereas others selectively enhanced the proliferation of beneficial bacteria such as Bifidobacterium thermophilum. These results suggest that A. nodosum can exert both pathogen-limiting and microbiota-supporting effects, with the magnitude and nature of these activities depending on the extraction process used to obtain the bioactive compounds [29]. An in vitro analysis assessed the antioxidant and antibacterial efficacy of Ascophyllum nodosum extracts against Escherichia coli strains typically linked to enteric diseases in swine. The findings revealed that A. nodosum significantly suppressed the growth of both F4+ and F18+ E. coli strains. Furthermore, the extract displayed potent, dose-dependent antioxidant activity, outperforming the other seaweed extracts evaluated in the study. These results indicate that A. nodosum exhibits both antibacterial and antioxidant capabilities, suggesting its utility as a natural feed additive to promote animal health and decrease reliance on conventional antibiotics [30].
Prebiotic Effects
Ascophyllum nodosum has shown promising prebiotic properties by promoting the growth and activity of beneficial gut microorganisms. These effects may contribute to improved digestive health, microbial balance, and metabolic function.
A study explored how enzymatic treatment and lactic acid fermentation could alter the composition and biological activity of polysaccharides obtained from Ascophyllum nodosum. These processing methods increased the concentration of carbohydrate-rich and sulfated components, indicating an enrichment of biologically active polysaccharide fractions. Evaluation of the modified products in animal models showed beneficial effects on metabolic and gastrointestinal parameters, including reductions in blood glucose levels and enhanced production of short-chain fatty acids (SCFAs) by the gut microbiota. Increased SCFA generation, particularly acetate, suggests improved microbial fermentation and a healthier intestinal environment. Overall, the results indicate that A. nodosum-derived polysaccharides may function as prebiotic ingredients while also supporting glucose regulation and digestive health [33]. Scientists examined the prebiotic viability of Ascophyllum nodosum and Lithothamnium calcareum by testing them with the probiotic strains Lactiplantibacillus plantarum and Limosilactobacillus reuteri. The study found that these algal extracts encouraged the proliferation of both beneficial bacteria and improved their functional performance during the incubation period. Furthermore, the presence of the algae in co-culture heightened antioxidant activity and successfully restricted the spread of Escherichia coli. Taken together, these results imply that Ascophyllum nodosum serves as an effective prebiotic, fostering the growth of healthy gut microbiota and curbing harmful pathogens, which contributes to overall digestive health and microbial equilibrium [34].
Immunomodulatory effect
Ascophyllum nodosum has demonstrated immunomodulatory activity by enhancing innate immune responses and supporting host defense mechanisms. These effects may help improve immune function and resilience against infections. A study of 95 weaned pigs assessed how Ascophyllum nodosum seaweed extract impacts growth and immune reactions after exposure to Salmonella typhimurium. The results indicated that pigs receiving the supplement experienced better growth performance, with the most significant increases in final body weight and average daily gain observed at a 1.0% inclusion rate. Although the Salmonella infection hindered growth rates, feed efficiency, and feed intake, the dietary inclusion of A. nodosum provided noticeable benefits to the animals' performance. Furthermore, laboratory tests revealed that high levels of the extract encouraged porcine alveolar macrophages to secrete prostaglandin E2 (PGE2), pointing to immunomodulatory properties. Ultimately, these results imply that Ascophyllum nodosum can assist in maintaining growth and modulating immune responses in young pigs [35]. Research has shown that an aqueous Ascophyllum nodosum extract (Tasco®) defends Caenorhabditis elegans from Pseudomonas aeruginosa infection by simultaneously strengthening the host's innate immunity and inhibiting bacterial virulence. When administered at a concentration of 300 µg/mL, the extract triggered the expression of various immune-associated genes, such as those responsible for antibacterial proteins, lysozymes, and other defense molecules. In addition, the extract decreased the secretion of bacterial virulence factorsspecifically lipases, proteases, pyocyanin, and hydrogen cyanideby suppressing vital quorum-sensing regulatory genes, including lasI, lasR, rhlI, and rhlR. These results demonstrate that A. nodosum provides protection via a dual-action mechanism that both stimulates host immune responses and disrupts bacterial virulence pathways [36].
Anti-inflammatory Effects
Ascophyllum nodosum exhibits potent anti-inflammatory activity by regulating inflammatory mediators and signaling pathways. These properties may help support immune balance and overall health. An investigation explored the anti-inflammatory mechanisms of two novel fucoidans, ANP-6 and ANP-7, derived from Ascophyllum nodosum. In an in vitro model using LPS-stimulated macrophages, both compounds effectively suppressed nitric oxide (NO) production and regulated the expression of critical inflammatory mediators, specifically IL-6, IL-10, TNF-α, IL-1β, iNOS, and COX-2. Further analysis revealed that these fucoidans inhibited the expression of TLR-2 and TLR-4, indicating that their anti-inflammatory effects occur via the suppression of the TLR/NF-κB signaling pathway. Notably, ANP-6 demonstrated superior efficacy compared to ANP-7, suggesting that the molecular weight of these A. nodosum-derived fucoidans is a significant factor in their biological activity [31].
In another study, Researchers investigated the anti-inflammatory and gastroprotective capabilities of water-based extracts derived from Ascophyllum nodosum and Fucus vesiculosus through both cell culture experiments and an in vivo model of intestinal inflammation using Drosophila melanogaster. The findings revealed that Ascophyllum nodosum notably lowered nitric oxide levels in macrophages triggered by lipopolysaccharides and suppressed the release of various pro-inflammatory markers, such as TNF-α, IL-6, IL-33, CXCL9, CXCL10, CXCL11, and CCL7. Additionally, the extract blocked the TLR4-mediated NF-κB pathway, which is critical for regulating inflammation. In the Drosophila model, the treatment improved intestinal barrier function, lowered mortality rates, and mitigated immune responses caused by infection. Collectively, these results indicate that Ascophyllum nodosum exhibits strong anti-inflammatory activity, potentially promoting gut health and resilience by regulating inflammatory signaling [32].
Antioxidant Effects
Oxidative stress plays an important role in the development of numerous diseases and age-related disorders in animals. Several studies have demonstrated that Ascophyllum nodosum possesses potent antioxidant properties.
The antioxidant properties of Ascophyllum nodosum and Fucus vesiculosus extracts were investigated using both intestinal epithelial cell cultures and the nematode Caenorhabditis elegans as experimental models. In intestinal cells, both seaweed extracts were effective in lowering oxidative stress by suppressing the generation of reactive oxygen species (ROS). Experiments in C. elegans further demonstrated that prior exposure to A. nodosum enhanced the organism’s ability to withstand oxidative damage induced by paraquat, resulting in less impairment of movement and favorable regulation of antioxidant defense mechanisms. The extract also promoted healthier aging under normal conditions and lowered the expression of biomarkers associated with oxidative stress when animals were exposed to oxidative challenges. Collectively, these findings highlight the strong antioxidant capacity of A. nodosum and suggest its potential value as a functional ingredient for improving health, resilience, and protection against oxidative stress in animals [21]. A series of studies conducted on pasture investigated the influence of the seaweed-derived product Tasco-Forage (Ascophyllum nodosum) on the antioxidant profiles of grazing ruminants. Among lambs grazing tall fescue treated with the supplement, researchers observed enhanced daily weight gains alongside tendencies for increased concentrations of whole-blood selenium and serum vitamin A. Conversely, trials involving Angus and Angus-cross steers demonstrated that grazing on tall fescue infected with endophytes typically resulted in a diminished antioxidant status, specifically characterized by suppressed levels of serum vitamin E and vitamin A. Despite the decline in antioxidant status observed in animals grazing endophyte-infected tall fescue, the inclusion of the Ascophyllum nodosum-derived supplement was found to enhance the antioxidant properties of the forage itself by increasing superoxide dismutase (SOD) activity. Supplemented animals also demonstrated favorable changes in several biomarkers associated with antioxidant defense. Collectively, these studies indicate that A. nodosum supplementation may strengthen antioxidant capacity in both pasture plants and grazing ruminants, thereby contributing to improved resistance against oxidative stress and supporting overall animal health [22]. A laboratory-based study explored whether a phlorotannin-rich extract derived from Ascophyllum nodosum could influence biological mechanisms linked to the aging process. The researchers observed that the extract limited the accumulation of reactive oxygen species (ROS) in epithelial cells subjected to oxidative stress, indicating an ability to counteract oxidative damage. In activated macrophages, treatment with the extract also suppressed the production of the inflammatory cytokines TNF-α and IL-6. Moreover, exposure to the extract promoted greater nuclear activity of SIRT1, a protein widely associated with cellular maintenance, longevity, and healthy aging. Taken together, these findings indicate that A. nodosum phlorotannins may protect cells from age-related deterioration by modulating both oxidative and inflammatory pathways [23].
Antidiabetic Effects
Ascophyllum nodosum has shown promising antidiabetic effects through its ability to modulate glucose metabolism and improve glycemic control. Although current evidence is limited to in vitro studies, animal models, and human clinical trials, these findings suggest its potential application in supporting metabolic health in companion animals. Research examining the antidiabetic effects of Ascophyllum nodosum has demonstrated that its extracts can influence several aspects of glucose metabolism. In vitro, the extracts inhibited intestinal α-glucosidase, an enzyme involved in carbohydrate digestion, and promoted glucose uptake by adipocyte cells. In a mouse model of streptozotocin-induced diabetes, administration of polyphenol-rich A. nodosum extracts over a four-week period resulted in improved glycemic control, evidenced by lower fasting blood glucose concentrations and a reduced rise in blood glucose following a sucrose challenge. Treated animals also exhibited decreases in total cholesterol and glycated serum protein levels relative to untreated diabetic controls. Furthermore, polyphenol supplementation aided in replenishing hepatic glycogen stores, while all tested A. nodosum preparations enhanced systemic antioxidant capacity. Together, these results indicate that A. nodosum may contribute to metabolic health by supporting glucose regulation, strengthening antioxidant defenses, and improving key markers associated with diabetes [13]. A review examining the antidiabetic capacity of Ascophyllum nodosum emphasized its abundance of bioactive constituents, such as fucoxanthin, phlorotannins, and phenolic compounds, all of which display potent antioxidant and glucose-regulating effects. The study noted that extracts from the alga act as inhibitors of α-amylase and α-glucosidase , enzymes crucial for digestion, thereby decelerating carbohydrate breakdown and intestinal glucose absorption. This inhibition contributes to lowered postprandial blood glucose levels and enhanced glycemic management. Ultimately, the authors suggested that integrating A. nodosum into the diet serves as an effective strategy for controlling glycemic responses and fostering long-term metabolic health [24]. In a six-month randomized, placebo-controlled clinical trial, 175 individuals with type 2 diabetes were assessed to determine the metabolic effects of a nutraceutical formulation containing polyphenol-rich extracts of Ascophyllum nodosum and Fucus vesiculosus in combination with chromium picolinate. When used as an adjunct to standard antidiabetic treatment, the supplement produced significant improvements in glycemic parameters, including reductions in glycated hemoglobin (HbA1c), fasting blood glucose, and postprandial glucose concentrations compared with placebo-treated participants. Although the intervention did not significantly alter overall lipid profile measurements, participants receiving the supplement showed a tendency toward lower triglyceride levels. These results indicate that A. nodosum-containing polyphenol formulations may enhance glucose regulation and contribute to better metabolic control in patients with type 2 diabetes [25].
Anticancer Effects
Ascophyllum nodosum has demonstrated promising anticancer activity through bioactive compounds that can inhibit tumor growth and enhance antitumor immune responses. An experimental investigation assessed the antitumor and antiproliferative potential of fucoidan extracted from Ascophyllum nodosum using a human non-small-cell lung carcinoma (NSCLC) cell line and an in vivo murine tumor model. In vitro results indicated that the extract reversibly suppressed cancer cell growth by triggering cell cycle arrest during the G1 phase. In vivo, administration of the extract at subtoxic levels effectively inhibited tumor progression in NSCLC-bearing mice. These data indicate that A. nodosum-derived fucoidan exhibits significant anticancer activity, highlighting its potential utility as a therapeutic intervention in oncology [26]. Researchers investigated the antitumor and preventive capabilities of ascophyllan, a sulfated polysaccharide extracted from Ascophyllum nodosum, using a mouse melanoma model. The study demonstrated that ascophyllan improves the activation and migration of dendritic cells, promotes Th1 immune responses, and elevates the production of TNF-α and IFN-γ in tumor-bearing subjects. Furthermore, when combined with ovalbumin (OVA), ascophyllan stimulated antigen-specific CD8+ and CD4+ T-cell responses, heightened antibody production, and improved immune memory, which collectively led to a substantial suppression of tumor proliferation. This combination also significantly curtailed liver metastasis and tumor invasion, while providing robust protection against future tumor challenges. These findings indicate that ascophyllan exhibits potent immunomodulatory and antitumor activity, suggesting its potential as an effective adjuvant for cancer vaccine development [27].
V. Conclusion
Ascophyllum nodosum has emerged as a promising functional ingredient in companion animal nutrition due to its rich composition of bioactive compounds and diverse biological activities. Current evidence indicates that supplementation with A. nodosum may support oral health, modulate immune and inflammatory responses, enhance antioxidant defenses, and contribute to overall health and well-being. Among its reported applications, its role in reducing dental plaque and calculus accumulation is supported by the strongest evidence in companion animals. While findings from experimental and clinical studies highlight considerable therapeutic potential, further research is required to clarify its mechanisms of action.
