[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

Watch now[toc position='left'] Introduction Magnesium is an essential dietary mineral. It plays critical roles in myriad physiological processes, serving as a cofactor to more than 300 enzymes in the human body and maintaining the integrity of cellular structures and DNA. Magnesium deficiency is widespread, affecting more than half of people in the U.S. and increasing the risk of many chronic conditions, including cancer, metabolic disorders, and neurodegenerative diseases. At a glance, magnesium participates in: Enzymatic reactions, serving as a cofactor for more than 300 enzymes involved in variou... magnesium brain nutrition supplements micronutrients

Watch nowMorning sickness affects up to 85 percent of pregnant women and is caused by hormonal changes during early pregnancy. Vitamin B6, antihistamines, and some prescription medications are used to treat nausea and vomiting during pregnancy; however, additional treatments that address hormonal imbalances are needed. Findings of a new report show that probiotics reduced nausea and vomiting and improved quality of life in pregnant women. Levels of hormones such as estrogen and progesterone fluctuate throughout pregnancy altering the composition of the gut microbiota and gastrointestinal function. Gut ... probiotics pregnancy

Watch nowAlzheimer’s disease, the most common type of neurodegenerative disease in older adults, causes a progressive deterioration of cognitive function. Recent research indicates that folate (vitamin B9) deficiency may play a role in Alzheimer’s pathology (https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fasebj.30.1_supplement.1171.10?legid=fasebj%3B30%2F1_Supplement%2F1171.10&related-urls=yes) along with other micronutrients, such as vitamin A (https://pubmed.ncbi.nlm.nih.gov/28130638/). A recent systematic review and meta-analysis reports that folate deficiency increases the risk for Alzhe... brain alzheimer's micronutrients folate neurodegeneration

Eating fruits and vegetables, which are rich in a variety of beneficial bioactive compounds, may slow cardiovascular aging. Investigators tested the effects of anthocyanin compounds from blueberries on flow-mediated dilation. Flow-mediated dilation refers to the capacity of an artery to expand in response to increased blood flow. It is a widely accepted measure of vascular endothelial function, and poor flow-mediated dilation is a recognized fe... diet heart disease cardiovascular
