[toc] Urolithin A is a postbiotic—a compound our gut microbes can form from ellagitannins and ellagic acid, polyphenols found in foods such as pomegranates, strawberries, and walnuts. Because production depends on the presence of specific gut microbes, people fall into distinct "metabotypes" (A = good UA producers, B = partial producers, 0 = non-producers), and only a minority make large amounts from diet alone. Therefore, purified UA supplements bypass that microbiome variability.[ref doi='10.3389/fmicb.2017.01521'] Mechanistically UA is best known as an inducer of mitophagy—the selective au... immune system gut aging prebiotics urolithin a microbiome

Watch now[toc position='left'] The blood-brain barrier comprises various membranes that separate the central nervous system (CNS) and the peripheral circulatory system. The purpose of this barrier is to allow the passage of nutrients and cell signals from the bloodstream to nerves and supporting cells in the CNS while excluding harmful substances. Genetic predispositions, environmental exposures, and aging may weaken the integrity of this barrier, allowing endotoxins and inflammatory immune cells to infiltrate the brain, contributing to accelerated brain aging and the risk of neurodegenerative diseases... omega-3 immune system blood-brain barrier brain alzheimer's gut obesity
Read more[toc position='left'] Thymic involution is the process by which the thymus shrinks with age and produces fewer T cells, impairing immunity and increasing the risk of infection in older adults. In addition, thymic involution increases the risk of cancer and autoimmunity with age. However, research has identified some of the mechanisms of thymic involution and highlighted possible strategies to improve immunity: By activating PPAR-gamma, a protein that regulates fat metabolism, caloric restriction reduced the rate of thymic involution in mice and increased the number and diversity of circulatin... thymic involution immune system thymus autoimmunity

Read more[toc position='left'] Background Vitamin C, also known as ascorbic acid, is an essential nutrient, widely recognized for its antioxidant properties. These properties arise from its potent redox potential due to its capacity to donate electrons to oxidized molecules. Even in small quantities vitamin C can protect critical molecules in the body such as proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA) from damage by reactive oxygen species, which are generated during normal metabolism, by active immune cells, and through exposure to toxins and pollutants (e.g., certain chemotherap... cancer nutrition exercise interesting
