The gut microbiome represents a contributory factor in ageing-related health loss and in several non-communicable diseases across all age groups. Indeed, age-related alterations in the gut microbiome are the result of personal factors, physiological decline, and by lifestyle-linked factors such as diet, medication, and decreased social contact. Therefore, resetting gut microbiome-derived signals of ‘unhealthy’ aging through personalized or subpopulation-level microbiome-associated interventions represents a new research area informed by large shotgun metagenomics-based studies and data analytics (1).
This study gives importance to applying gut microbiota as biomarkers of aging, which may enable monitoring of the efficacy of interventions and the early detection of age-related decline (2). The therapeutic approaches targeting the microbiome, using a diet rich in fibers, polyunsaturated fatty acids, polyphenols, probiotics, prebiotics, postbiotics, and fecal microbiota transplantation, have a promising effect, correcting biome-aging through a balanced gut microbiota (3). Also, dietary approaches, especially a diet supplemented with a higher amount of fibers, plant-proteins, polyphenols, and fermented foods, boost beneficial microbes and derivatives, including SCFAs, which help suppress inflammation and protect against diseases, including cardiovascular diseases, diabetes, and neurodegenerative disorders (4).
These approaches foster an increased number of beneficial functional microbes, as well as increased production of specific microbe-derived metabolites, including SCFAs and neurotransmitters. This, in effect, triggers metabolite synthesis, which boosts mucus secretion, hence working towards successful aging (3).
Future studies should focus on the development of more targeted and individualized approaches to manipulating the microbiome that are specific to the individual’s microbial biomarker pattern, diet, genotype, and metabolic phenotype (5).

The gut microbiome consists of beneficial bacteria that play an important role in digestion, immunity, and overall health. With aging, the diversity of gut bacteria often decreases, which may increase the risk of chronic diseases such as diabetes, heart disease, inflammation, and cognitive decline.
Maintaining a healthy gut microbiome can support healthy aging by improving immune function and reducing inflammation. Diet is a key factor in gut health. Eating fiber-rich foods, fruits, vegetables, whole grains, and fermented foods like yogurt helps promote beneficial bacteria. Probiotics, regular physical activity, and avoiding unnecessary antibiotics can also help maintain gut balance in older adults.
In conclusion, improving gut health through simple lifestyle and dietary changes is a promising and cost-effective approach to support healthy aging.

The structure helps in understanding the gut microbiome, which is related to phosphorylation, to keep the process working in the enzymes and how its function impacts metabolic activity, which affects immunity. This may elevate the risk of chronic conditions, including diabetes, cardiovascular disease, inflammation, and cognitive deterioration.
These approaches can lead to significant health effects, and aging can be elevated. It needs an early intervention and monitoring of the decline in health. The data indicate that senolytic treatment diminishes intestinal senescence and inflammation while modifying particular microbiota profiles, suggesting that optimized senolytic regimens may enhance health by mitigating intestinal senescence, inflammation, and microbial dysbiosis in older individuals.

The gut microbiome is our lifetime companion, regulating our health from birth throughout the lifespan. The gut microbiome composition changes continually with age, influencing both physiological and immunological development. As individuals age, significant changes in factors such as diet, lifestyle, and physiology contribute to a process termed “biome-aging”—an aging-associated gut dysbiosis characterized by the loss of beneficial commensals, proliferation of pathogenic microbes, and increased intestinal permeability (“leaky gut”). Concurrently, the decline in functional microbes impairs nutrient metabolism and biosynthesis, leading to nutrient malabsorption and deficiencies in microbially derived essential nutrients. Factors including polypharmacy, physical inactivity, social isolation, hormonal changes due to gastrointestinal tract (GIT) deterioration, and malnutrition are all known to influence human aging as well as biome-aging. The overprescription of non-antibiotic medications has also been linked to severe changes in the GIT and decreased gut microbiome diversity in aging model studies (Kadyan et al., 2025)
Integrating knowledge from Ayurveda, which emphasizes the importance of Trayopastamba - diet (Ahara), sleep (Nidra), and regulated lifestyle (Brahmacharya) in maintaining gut microbiome health. Ayurvedic practices advocate for a balanced diet tailored to individual Doshas, regular sleep patterns, stress management techniques, and a disciplined lifestyle, all of which contribute to maintaining a harmonious gut microbiome. By understanding and nurturing the gut microbiome through these integrated approaches, we can enhance overall health outcomes and prevent various diseases associated with microbial imbalance (Soman & Marikutty TC, 2025).
The interaction of various phytoconstituents present in the medicinal food Homologous plants with the gut microbiota has a two-way effect. While the phytoconstituents can modulate the growth of useful gut bacteria, such as Bifidobacterium and Lactobacillus, these microbes have enzymes that help in the transformation of plant moieties into active metabolites, which have beneficial effects(Bhawana Jangra et al., 2025).
