Telomeres serve as protective caps at the ends of chromosomes, and when they shrink too much, cells stop dividing and age. Shorter telomeres have been linked to an increased risk for age-related diseases and premature death. A recent study found that daily vitamin D3 supplementation slowed telomere shortening by about 25% over four years in older adults. Researchers recruited 1,031 participants from the large VITAL (https://www.vitalstudy.org) trial who took vitamin D3 (2,000 IU daily), omega-3 fatty acids (1 gram daily), both, or a placebo for four years. The researchers measured each person'... vitamin d telomeres supplements aging

Watch nowBeta-lactoglobulin is a protein in breast milk. It binds to retinol, a form of vitamin A that plays a crucial role in neurodevelopment, facilitating its transport. A recent study found that nanoplastic exposure induces structural changes in beta-lactoglobulin, impairing retinol binding and transport. Researchers conducted a multi-part study to investigate the effect of polystyrene nanoparticles on beta-lactoglobulin. First, they measured changes in the protein's structure and its ability to bind retinol. Then, they examined polystyrene's effects on lysozyme, an antibacterial protein found in ... nutrition development vitamin a breast milk Microplastics
Read moreGraying hair is a cardinal sign of aging, typically beginning in a person’s fourth or fifth decade. Nutritional deficiencies, including low intake of protein, vitamin B12, iron, and copper, can contribute to premature graying. However, a recent review found that some medications may promote gray hair re-pigmentation. Researchers reviewed 27 studies and case reports of medication-induced gray hair re-pigmentation, totaling 133 patients. They categorized the various drugs as anti-inflammatories, stimulators of melanogenesis (the production of melanin, the pigment responsible for hair, skin, and... nutrition aging inflammation drug Hair

The data analyses revealed that the severe disease infection was less prevalent in patients with vitamin D sufficiency (63·6% vs. 77·2% p=0·02).” Mortality: No one under the age of 40 died. In those over 40, 20% were vitamin D insufficient but they comprised of 90.3% of the deaths. ... vitamin d covid-19
