Healthy Aging

The goal of this clinical trial is to learn if AppleX™ Apple Extract can help lower systemic inflammation in adults aged 45-70 with signs of low-grade inflammation. It will also look at the extract's effects on fatigue, joint comfort, and biological aging metrics. The main questions it aims to answer are: * Does taking AppleX™ Apple Extract daily lower high-sensitivity C-reactive protein (hsCRP) levels, a key marker of inflammation in the blood? * Does AppleX™ Apple Extract improve participant-reported fatigue and joint comfort? * Does the extract slow down biological or epigenetic aging metrics compared to a placebo? Researchers will compare AppleX™ Apple Extract to a placebo (a look-alike capsule that contains no active ingredients) to see if the apple extract has a measurable anti-inflammatory and healthy aging effect.

The goal of this clinical trial is to learn if a dietary supplement called Miricell works to improve cellular health and signs of healthy aging in adults. It will also learn about the safety of Miricell. The main questions it aims to answer are: * Does Miricell improve markers of autophagy, which is the body's natural process for recycling damaged cells? * Does Miricell support brain health, metabolic health, and visible signs of aging? * What medical problems, if any, do participants experience while taking Miricell? Researchers will compare Miricell to a placebo (a look-alike capsule that contains no active ingredients) to see if Miricell works better to support healthy aging. Participants will: * Take either one Miricell capsule or a placebo every day for 12 weeks with a morning meal. * Visit the research clinic four times over the course of the study for checkups and tests. * Complete memory and thinking tests, track their daily physical activity, and give blood samples to measure health changes.

The goal of this study is to determine the impact of MVM supplementation on clinical and biochemical markers associated with healthy aging, with a particular focus on mitochondrial function and metabolism. Specifically, changes in mitochondrial respiration using isolated blood cells will be measured. This method has been used to compare with various other age-related markers of health such as physical function, gait speed, and resting metabolic rate. It is hypothesize that MVM supplementation will impact the function of blood cells. MVM supplementation impacts other markers of health, including serum nutrient levels, metabolomic profiles, physical function, and skeletal muscle composition and quality will be explored. These comprehensive assessments will provide insights into the potential benefits of MVM supplementation for healthy aging and address critical gaps in our understanding of its immediate effects. Further, this study will aid in the understanding of how multivitamin supplements can support heathy aging in mid-life adults, a key time to start including wellness programs in people's lives. The study cohort will consist of 150 sedentary men and women aged 40-60-years of age. A double-blind, three-arm, placebo-controlled randomized clinical trial will be conducted. Participants will receive a daily oral tablet containing one of two possible formulations of vitamins and minerals or a placebo. The three groups will be MVM "GOLD" blend formula, the US Restage MVM "US CORE", and the placebo group.

The goal of the proposed project is to evaluate a mechanical intervention (sports bras designed specifically for full busted women) to alleviate neck, shoulder, arm, and back pain in full-busted women and investigate the contribution of non-mechanical pathways associated with this type of pain in women. Specifically, the investigators will investigate how sex-hormones, inflammation, and remapping of specific regions of the brain contribute to the manifestation of neck, shoulder, arm, and back pain in full-busted women across the lifespan.

his study investigates whether eating lean beef every day can help support brain health and healthy aging in older adults. As people age, protecting memory and cognitive function becomes increasingly important. Lean beef is a rich source of essential nutrients-such as vitamin B12, iron, zinc, and creatine-that are known to support brain function. However, the direct biological effects of a beef-rich diet on brain health markers are not fully understood. In this study, researchers will recruit 20 generally healthy older adults (aged 65 and older) to participate in a dietary feeding trial. Participants will complete two separate 2-week dietary phases. During one phase, participants will consume 5.5 ounces (156 grams) of provided lean beef daily. During the other phase, they will consume an iso-caloric, protein-matched, non-beef control food daily. A two-week "washout" period, where participants return to their normal diets, will separate the two phases to ensure there are no overlapping effects. Researchers will collect blood, urine, stool, and saliva samples at the beginning and end of each 2-week dietary phase. These samples will be analyzed to see if the lean beef diet improves specific biological markers in the blood related to memory, nerve protection, and overall brain aging. Ultimately, the findings from this study will help determine if incorporating lean beef into a regular diet can be a natural, food-based strategy to help preserve neurological health in older adults.

Background: Population aging is accelerating rapidly in Israel and worldwide, necessitating adaptation of the healthcare system and considering new approaches that serve the needs of older adult populations. Working hypothesis and aims: We hypothesize that a personalized health and behavior intervention program will decrease the biological age as assessed by several biological aging clocks and improve functional and cognitive performance among older adults. Methods: We propose to conduct a randomized study among healthy community-dwelling elderly subjects (\>50 years old). The study will include an extensive aging assessment and imaging protocol (baseline assessment), including comprehensive physical, functional, sensory, cognitive, and mental assessment. Each participant in the intervention group will receive a personalized intervention program based on an integrative systems approach analysis. In addition, a uniquely developed application will track compliance and monitor physiological data through a provided wearable device. The control group will be assessed at baseline without receiving an intervention program. Each participant will visit the center aging after 6 months for a blood test and after 12 months for a second extensive diagnostic protocol, similar to the baseline assessment protocol. About 1,500 subjects will be recruited to participate in the study. Expected results: Obtaining data at two points will allow us to examine efficiency and compliance with a personalized intervention program based on integrative systems analysis models. We expect biological age, general well-being, and various clinical and psychosocial outcomes in the intervention group will decrease and improve compared to the control group. Study importance and relevance: The obtained results may help establish evidence-based healthy aging diagnostics protocols and an effective personalized intervention program that might be applied, with proper modifications, to national healthcare organizations for the general older adult population. In addition, to provides a scientific basis on which policymakers and intervention programs can rely to develop national guidelines for promoting extended health.

The goal of this observational study is to evaluate the reliability, usability, and feasibility of the MEVA Cognitive Wellness Platform in community-dwelling adults aged 55 to 75. The main questions it aims to answer are: How consistent is the MEVA Global Cognitive Index when participants complete the MEVA activities again approximately 14 days later? How usable and acceptable is the MEVA platform for older adults in community settings? What completion rates, data quality patterns, and participant feedback are observed during use of the platform? Participants will: Complete a baseline study visit lasting approximately 45 to 60 minutes Complete a 7-activity digital cognitive wellness battery Answer questionnaires about usability, technology acceptance, and wellness experience Complete the Saint Louis University Mental Status (SLUMS) examination as an exploratory comparison measure If selected for the retest group, return approximately 14 days later to complete the MEVA activities again MEVA is being evaluated as a cognitive wellness platform. It is not intended to diagnose, treat, prevent, screen for, or monitor any disease or medical condition.

Taiwan is entering a super-aged society in 2025, with more than 20% of the population aged 65 years or older. This rapid demographic shift, combined with increasing rates of chronic diseases, frailty, and dementia, has created growing challenges for healthcare and caregiving systems. Yunlin County, particularly its coastal region, has been one of Taiwan's earliest super-aged areas, showing higher rates of diabetes (10.5%), hypertension (28%), hyperlipidemia (26%), dementia (8%), and depression (12%) compared with national averages. Lifestyle factors such as tobacco (30%), betel nut (8%), and alcohol (15%) use are also more prevalent among local residents. From 2022 to 2024, health screenings at CMU Beigang Hospital revealed a 36.1% abnormality rate among 12,222 visits, while another 5,965 assessments from the county's ICOPE program showed similarly high rates. Many older adults, particularly retired agricultural and fishing workers, experience sedentary lifestyles and polypharmacy-related risks, which worsen frailty, insomnia, depression, and cognitive decline. Low general and digital health literacy further limits their ability to adopt preventive behaviors, forming a vicious cycle between poor health and aging. To address these challenges, the Ministry of Health and Welfare launched the "Healthy Taiwan Cultivation Plan." In alignment with this initiative, this project-led by CMU Beigang Hospital in collaboration with the National Health Research Institutes-aims to develop a wearable- and mobile-based health promotion model for rural older adults. The study will integrate research-grade actigraphy (Geneactiv), a mobile health platform ("iMED"), and the in-bed sensor iCue to monitor behavior, promote active aging, and enhance health and digital literacy. Ultimately, this project seeks to establish Taiwan's first integrated digital aging database and identify digital biomarkers for predicting cognitive and functional decline in older adults.

The overall objective of this study is to assess the effect of an adaptive computerized cognitive training program for executive functions (CogniFit platform) on improving these functions in older adults, both healthy and with mild cognitive impairment (MCI), as well as to examine the potential transfer effects of this training on memory. Additionally, determine the impact of the intervention on the emotional symptoms, behavioral disorders, or quality of life of the participants.

This study will evaluate whether a wearable robotic exoskeleton can improve mobility, balance, and walking in healthy older adults and in individuals living with Parkinson's disease, populations at high risk of falls and mobility limitations. Participants will attend two laboratory sessions. The first session includes clinical assessments, fitting and familiarization with the exoskeleton, and interviews to explore user perceptions. The second session involves performing functional mobility tasks (e.g., walking, standing, turning) with and without the exoskeleton and under different assistance levels, while movement is measured using wearable sensors. The study will assess the immediate effects of the exoskeleton on mobility, compare assistance levels, identify which participants benefit most, and explore user experience and acceptability. Findings will help inform the development and implementation of assistive technologies to support mobility in healthy aging and in individuals with Parkinson's disease.

This research study is investigating whether people with Alzheimer's disease (AD) experience more changes to swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe AD is high (85-93%), yet little is known about how swallow function evolves throughout the disease course in people with AD. The overall objective of this study is to evaluate swallowing function in adults with and without Alzheimer's disease. The investigator will also be involving the primary caregivers of individuals with Alzheimer's that are enrolled in the study to better understand the impact of swallowing impairments on the primary caregivers of those with Alzheimer's Disease. Healthy adults and individuals with Alzheimer's disease will: * undergo tests of cough and swallow function * undergo tests of grip and tongue strength * complete questionnaires Caregivers of individuals with Alzheimer's disease will also complete questionnaires.

African Americans are less likely to receive quality end-of-life (EoL) care. Addressing disparities in EoL care will need efforts to support a better understanding of African American patients' EoL cultural values and preferences for EoL communication and the impact of historical and ongoing care delivery inequities in healthcare settings. Our proposed "Caring for Older African Americans" training program is designed to empower clinicians to improve goal-concordant EoL care delivery by using community-developed storytelling videos to create empathy with experiences of racism in EoL care, guidelines for culturally concordant EoL care delivery, and an implicit bias recognition and management training to mitigate bias in goals of care communication.

This is a multi-center, cross-sectional, observational study aimed at developing biological age calculators specifically for the Russian population investigating various aging phenotypes. Aging is a complex process that varies greatly between individuals, meaning that chronological age does not always reflect one's biological health status. The primary goal of this study is to identify and analyze a comprehensive set of markers (including socioeconomic factors, lifestyle, physical parameters, cognitive function, and laboratory biomarkers) that best reflect the aging process. Using this data, researchers will create a mathematical model to estimate a person's "biological age." The study plans to enroll at least 3,500 male and female volunteers aged 18 years and older from across Russia. Participants will be divided into 5-year age groups (e.g., 18-24, 25-29, up to 90+ years) to ensure broad representation. Participation involves a single visit to a clinical center. During this visit, participants will undergo: Interview and questionnaires (assessing health history, lifestyle, socioeconomic status, diet, sleep, and quality of life). Physical examination and anthropometric measurements (height, weight, blood pressure, grip strength). Functional and cognitive tests (e.g., walking speed, balance tests, memory and attention tasks tailored to age). Collection of biomaterials: blood (50 ml), urine, and stool samples for extensive laboratory analysis, including routine tests and specialized aging biomarkers. Part of the biomaterials will be biobanked for future scientific research. Instrumental examinations for a subset of participants: Depending on the center's capabilities and the study protocol, some participants may also undergo additional assessments such as densitometry (bone density scan), bioimpedance analysis (body composition), and brain MRI. The results are expected to lead to the creation of a validated biological age calculator for the Russian population. This tool could help identify targets for interventions to promote healthy aging and, in the future, potentially predict the risk of developing age-related chronic diseases.

In line with the ever-growing aging of Western populations, the development of preventive strategies to slow down the effects of aging on cardiovascular health represents a major challenge in order to preserve functional capacities and a sufficient quality of life in the elderly. The alteration of vascular function (at the cerebral and systemic level) with aging is an important feature in the clinical picture including a decrease in physical and cognitive capacities. Although physical activity is recognized as an essential means of combating the effects of aging, optimizing its effects by defining the most effective strategies of practice remains a key objective. Offering alternative interventions to exercise training is also necessary for people who are unwilling or unable to engage in a physical activity program. In this context, hypoxic conditioning, alone or in conjunction with rehabilitative exercise training, is a new therapeutic modality with strong preclinical validity, in particular from a cardiovascular standpoint, and used in other pathologies to improve cardiovascular function and exercise performance and quality of life. Our aim is, therefore, to investigate the effect of hypoxic conditioning (alone or in conjunction with exercise training) on cerebrovascular health in the elderly.

Aging-related functional declines are thought to be caused by hallmark biological processes that ultimately manifest in physical, mental, and metabolic impairments to compromise intrinsic capacity and healthspan. Exercise is the only multipotent treatment with promise to mitigate many of the aging hallmarks, but there is substantial variability in individual exercise responsiveness. Thus, the investigators approach to boosting exercise responsiveness in aging is to combine an exercise training prescription containing both endurance and resistance training (in alignment with DHHS guidelines) with a nitrate-enriched dietary supplement to augment the cellular, tissue, and systemic adaptations that induce myriad health benefits of exercise in older adults.

The goal of this clinical trial is to learn if daily collagen peptide supplementation can stabilize or lengthen telomeres and improve related markers of cellular aging in adults aged 50-70 years with overweight and low-to-moderate physical activity (healthy volunteers without major chronic disease). Main questions it aims to answer are: Does six months of collagen peptides stabilize or extend telomere length and increase telomerase activity compared with placebo? Are any telomere-related changes associated with lower inflammation, healthier body composition, and better functional health? Researchers will compare collagen as an intervention to a placebo group to see if collagen will influence aging markers. Participants will take collagen peptides or a placebo daily for 24 weeks. They will attend three study visits: one before starting the intervention (T0), one at 3 months (T1), and one at 6 months (T2). At each visit, blood samples will be collected to measure telomere length, telomerase activity, and inflammation/redox markers. Participants will also undergo body composition assessments using bioelectrical impedance, complete functional tests of muscle strength and mobility, and fill out questionnaires on health and vitality.

In recent years evidence has accumulated on the association between age-related decline in multisensory temporal processing and postural control. This proposed project aims at examining GABA-mediated inhibition as the potential mechanism behind this link. Our overarching hypothesis is that changes in the excitatory-inhibitory balance with a reduction of GABAergic inhibition is a common mechanism underlying age-related multisensory and postural deficits potentially mediated by age-related reduction in network segregation. To test this hypothesis, we will assess the relationship between age-related multisensory/postural deficits and age-related reduction in GABA concentration in related brain areas and probe the role of GABA-mediated inhibition using cognitive training that specifically targets inhibitory functions. Our multimodal approach is innovative, and findings from this study has the potential to lead to the development of safe and effective rehabilitation protocols for older adults with impaired multisensory temporal integration and postural control.

This study is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effects of Bifidobacterium adolescentis (iVS-1) supplementation on biological aging markers, metabolic health, and functional health outcomes in midlife adults. The study explores whether modulation of aging-related biological pathways through the gut microbiome may influence health-related outcomes.

The purpose of this study is to evaluate the effectiveness of two different educational models in improving the use of the "My Health Bank" App (a Personal Health Record system in Taiwan) among adults aged 50 and older. As Taiwan's population ages, digital health management has become essential, yet older adults often face a "digital divide." Participants will be randomly assigned to either a "Intensive Guided Learning group" (receiving one-on-one human instruction) or a "Flexible Self-study group" (using self-learning materials co-created with Generative AI). The study aims to compare the outcomes of these two groups in terms of enhancing digital health literacy, self-efficacy, and actual App usage behavior to identify more effective and scalable digital health education strategies.

This prospective study investigates the health effects of vegetarian and plant-based diets in middle-aged and older adults in Taiwan, specifically, recruiting 5000 Tzu Chi volunteers. Previous Tzu Chi cohorts found vegetarian diets were protectively associated with incidences of diabetes, stroke, gout, cataracts, insomnia, and gallstones, while reducing healthcare costs. The study also aims to clarify dietary patterns-particularly plant-based and vegetarian diets-and determine how potential deficiencies or excesses of various nutrients influence common aging-related health issues, including healthy cognitive decline, sarcopenia, and the risk of age-related diseases, in order to inform dietary and lifestyle recommendations that promote healthy aging and maintain physical function.

In this project, we aim to determine any potential effects of a weak electrical current applied to the neck or thoracic area on functional capacity and muscle activation. Healthy individuals will participate in one familiarization followed by up to 6 experimental sessions. Fatigability and motor function will be assessed in each test session.

This is a randomised, double-blind, placebo-controlled, parallel study to assess the effects of Urolithin A (Mitopure®) supplementation on muscle strength and performance in healthy middle-aged adults. Participants will be randomized to consume Mitopure® (500 mg), Mitopure® (1000 mg), or placebo once daily for 6 months.

The Impact 360 study will evaluate the effects of a combined intervention of exercise, mindfulness, and nutrition on 8 key indicators of health and the mechanisms that drive these changes. 60 subjects aged 50 to 75 without a current diagnosis of a brain disorder will be recruited. This study will follow a partial crossover design. All participants will receive the intervention. Participants randomized into the intervention group after their baseline screening will receive the 6-month intervention. Those randomized into the waitlist group will complete another assessment at the end of the 6-month care as usual phase before receiving the intervention.

Time processing, the ability to process and encode temporal information, is essential for cognitive functioning and for a large number of daily life activities. In particular, the processing of durations of several seconds is central to cognition, impaired in several pathologies, and has been associated with cognitive changes with advancing age. While behavioral studies have been conducted to specify the neural bases of temporal cognition and their association with other cognitive functions, the mechanisms underlying age-related changes, and individual differences, remain unknown. The project will characterize ageing effects on timing mechanisms and their neural underpinnings. Building on recent advances from neuroscience and age-related cognitive changes, the project focuses on the precision of duration processing, that declines with age, and the associated neural bases. Participants will perform a duration judgement task while (a) electroencephalography, and (b) functional magnetic resonance imaging activity are simultaneously recorded to investigate age effects on structural and functional network connectivity. In addition, striatal dopamine will be measured using a FDOPA PETscan. Evaluation of other temporal cognition processes and general cognition will also be performed. This combination offers a unique opportunity to accurately specifying the neurophysiological underpinning of aging effects on time processing changes. This project will further our understanding of the variability of cognitive performance with advancing age, and contribute to identifying new measures of temporal impairments.
