“Among large clinical studies, lutein intake between three and five milligrams per day was most effective for reducing the risk of age-related macular degeneration, a leading cause of vision loss in older adults.”

“Run the longevity report to learn more about genetic polymorphisms influencing the expression of FOXO Background FOX proteins are named for a gene found in fruit flies that causes the insects to have forked structures on their heads (providing the "F") and a particular group of specialized genes – known as a "box" (providing the "OX").”

“Robust evidence from epidemiological, clinical, rodent, and in vitro studies has demonstrated that sulforaphane exhibits antioxidant and anti-inflammatory properties and may be beneficial against a wide range of chronic and acute diseases, including autism, cancer, metabolic dysfunction, and many others and may ameliorate some of the harmful effects associated with exposure to air pollution.”

“Creatine improves vascular health To investigate creatine's effects on blood vessel health—specifically by measuring the ability of arteries and small blood vessels to increase in size to accommodate blood flow (known as endothelial function)—one study recruited 12 healthy men and women with an average age of 59 and supplemented them with creatine or a placebo for 28 days each.”

Biological aging clocks use DNA methylation patterns and other biomarkers to estimate different dimensions of biological aging, including how old the body appears at the molecular level, how quickly aging-related changes are accumulating, and whether lifestyle or medical interventions may be changing the trajectory of aging.

“Authors of a 2021 study recruited 50 participants (between ages 18 and 75 years) who were not consuming dietary supplements or large quantities of olive oil (greater than one tablespoon per day).”

“A meta-analysis led by Dr. Stuart Phillips found that individuals consuming 1.6 grams of protein per kilogram of body weight daily while engaging in resistance training increased their muscle mass by 27% and their strength by 10%, compared to those who trained without extra protein.”

“In laboratory tests, the redesigned factors produced more than 50-fold higher expression of stem-cell reprogramming markers than wild-type controls and generated stable induced pluripotent stem cell lines across multiple donors and delivery methods.”

“While aerobic exercise is often viewed preferentially through the lens of cardiovascular health, the diverse cascade of biological effects from exercise as a whole — and aerobic exercise, in particular — culminate to make it one of the most formidable and immediately practical real-world interventions for human aging and the brain.”

“Rhonda and Steve discuss calorie restriction, GLP-1 therapy, multivitamins, omega-3s, vitamin D, vegetables, red meat, exercise, heat exposure, sleep, social connection, consumer testing, AI-built clocks, partial reprogramming, and why no single intervention is likely to stop aging on its own.”
