Understanding the mechanisms of aging and how to extend healthspan is a critical area of research, especially as metabolic health is closely linked to longevity. Traditional lifespan studies in mice can be slow and expensive, making it challenging to evaluate numerous potential anti-aging interventions. This study introduces a short-term performance assay that allows researchers to quickly assess both the efficacy and potential side effects of various longevity treatments in mice over an 8-week period. In this study, five candidate anti-aging treatments were administered to mice: 17a-estradiol, rapamycin + Smer28, berberine + resveratrol, sildenafil, and pinealon. The researchers monitored body weight, temperature, and food intake, alongside assessments of grip strength, locomotor activity, cognitive function, social behavior, and various hematological and urinary parameters. Notably, 17a-estradiol led to significant weight loss (exact percentage not specified), increased grip strength, and dorsal alopecia, indicating metabolic remodeling. Sildenafil was found to reduce basal body temperature while preserving locomotor activity, suggesting a potential metabolic effect. The combination of berberine and resveratrol decreased food intake and fasting glucose levels, mimicking the metabolic effects of caloric restriction without major changes in physical performance. Conversely, rapamycin + Smer28 improved strength and sociability but caused anemia in 40% of the mice, indicating possible dose-dependent toxicity. Pinealon showed a trend toward improved working memory without detectable adverse effects, suggesting its potential as a safe intervention. These findings have practical implications for individuals interested in longevity and metabolic health. By understanding how different compounds affect metabolic parameters, individuals can make informed decisions about supplements or dietary interventions that may enhance their healthspan. For instance, those looking to manage their weight or improve their metabolic health might consider the effects of berberine and resveratrol, especially if they are also aiming to lower fasting glucose levels. The biomarkers relevant to this study include fasting glucose, which was significantly reduced by the berberine + resveratrol combination, and grip strength, which can be indicative of overall metabolic health and physical fitness. Individuals can utilize Metabolicum's calculators to assess their fasting glucose levels and monitor changes in their metabolic health over time. In conclusion, this study not only provides a rapid screening method for anti-aging interventions but also highlights the importance of metabolic health in longevity. As research continues to evolve, individuals should stay informed about emerging treatments and consider how they might integrate these findings into their health strategies.
