[toc position='left'] Biological aging clocks are among the most important tools in modern longevity science. They attempt to answer a deceptively simple question: can we measure how fast a person is aging biologically, rather than just counting the number of years they have been alive? The answer is yes—but with important caveats. Epigenetic clocks use patterns of DNA methylation, a chemical tagging system on DNA, to estimate different aspects of aging. Some clocks estimate chronological age. Others predict disease risk, mortality risk, or the current pace of biological aging. This means biol... epigenetics aging telomeres genetics stem cells omega-3 dna damage biomarkers vitamin d senescence multivitamin
Read moreScientists have proposed many ways to measure biological aging, but it is still unclear which markers best predict hard outcomes such as death. A new study tested 14 aging biomarkers side by side to see which were most strongly associated with mortality. The researchers analyzed data from 1,671 adults in the Berlin Aging Study II who were 60 to 80 years old at the start of the study. The biomarkers included inflammatory and hormone-related blood measures, physical function tests, cognitive performance, blood pressure, and DunedinPACE, an epigenetic score that uses chemical tags on DNA measure... aging epigenetics mortality

It is a member of the genus Lactobacillus, which comprises most of the bacteria that live on and in the human body. Lactic acid-producing bacteria, such as those in the Lactobacillus genus, are commonly used in probiotic supplements.[ref doi='10.1016/j.tim.2021.01.003'] Furthermore, some online resources provide step-by-step instructions for at-home bulk production of yogurt with L. reuteri enrichment.

Listen now[toc position='left'] Introduction Vitamin D is a fat-soluble vitamin that is stored in the liver and fatty tissues of the body. Perhaps best known for its role in maintaining calcium balance and bone health, vitamin D is critical in many physiological processes, such as blood pressure regulation, immune function, and cell growth. Poor vitamin D status is implicated in the pathogenesis of many acute and chronic diseases, including rickets, osteoporosis, multiple sclerosis, and cancer. Vitamin D is a controversial topic in the scientific community and has contributed to much debate regarding t... gut blood pressure vitamin d aging vitamin k calcium
Read more[toc position='left'] Background Collagens are major structural proteins in numerous body tissues, including tendons, ligaments, cartilage, skin, blood vessels, muscles, gut tissue, and dentin.[ref doi='10.1101/cshperspect.a004978'] They are the most abundant proteins in the body, comprising 30 percent of the total protein mass. The human body continuously manufactures collagens to maintain tissue structural integrity. However, aging drives a progressive decrease in protein synthesis and reduced capacity to produce new collagen.[ref doi='10.1016/S0047-6374(01)00337-2'] Collagens are also highl... interesting nutrition aging metabolism autoimmunity menopause
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

It is the fourth most widely prescribed medication in the United States, with more than 80 million prescriptions for the drug written yearly. Metformin is in a class of drugs called biguanides, which impede liver gluconeogenesis (glucose production in the liver), thereby decreasing glucose uptake in the gut and increasing overall glucose utilization by improving insulin sensitivity in skeletal muscle and fat tissue. Multiple studies demonstrate that metformin reduces fasting blood glucose levels by as much as 3.9... exercise aging diabetes
