- Role of Nutritional Supplements on Gut-Muscle Axis Across Age: a Mini-Review(2023) NUCCI, Ricardo Aparecido Baptista; NEHMI FILHO, Victor Abou; JACOB-FILHO, Wilson; OTOCH, Jose Pinhata; PESSOA, Ana Flavia MarcalSarcopenia is a progressive skeletal muscle disorder associated with aging, resulting in loss of muscle mass and function. It has been linked to inflammation, oxidative stress, insulin resistance, hormonal changes (i.e. alterations in the levels or activity of hormones which can occur due to a variety of factors, including aging, stress, disease, medication, and environmental factors), and impaired muscle satellite cell activation. The gut microbiome is also essential for muscle health, and supplements such as probiotics, prebiotics, protein, creatine, and beta-alanine can support muscle growth and function while also promoting gut health. Chronic low-grade inflammation is a leading cause of sarcopenia, which can activate signaling pathways that lead to muscle wasting and reduce muscle protein synthesis. Insulin resistance, hormonal changes, and impaired muscle satellite cell activation contribute to sarcopenia, and high levels of fat mass also play a role in the pathogenesis of sarcopenia. Resistance exercise and dietary supplementation have been shown to be effective treatments for sarcopenia. In addition, a combination of resistance exercise and supplementation has been shown to have a more significant beneficial effect on anthropometric and muscle function parameters, leading to a decrease in sarcopenic state. Thus, understanding the relationship between the gut microbiome and muscle metabolism is crucial for developing new treatments for sarcopenia across age groups.
