“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.”

“Neurogenesis Whereas the early view of the mammalian central nervous system presumed that it was a static complex incapable of change, a growing body of evidence suggests that it retains its capacity for synaptic pruning – the process that eliminates extra neurons and synaptic connections and establishes new neural circuits to increase the efficiency of neuronal transmissions – throughout life.”
“When we engage in high-intensity exercise, our muscles become mini biochemical laboratories, synthesizing compounds like lactate and myokines that circulate throughout the body and travel to our organs, where they exert a variety of signaling effects, including the synthesis of brain-derived neurotrophic factor (BDNF) in the brain.”
“Practical ways to use short bouts Choose the version that matches the goal rather than forcing every short activity into one label: For a vigorous fitness stimulus Select a familiar movement such as stairs, a stationary bike, uphill walking, or a bodyweight circuit.”
“If you focus on eating multiple protein-containing meals each day and are thoughtful about your sources, it's likely you'll meet daily protein needs and thrive, whether your goal is gaining more muscle or just staying strong into your later years.”
Liquid biopsies, a non-invasive cancer screening technology that includes GRAIL's Galleri test, could transform early detection and treatment by analyzing tumor-derived cells and components.
“However, a study involving more than 2,500 mentally healthy older adults found that a higher daily dietary magnesium intake (at least 407 milligrams) was linked to better overall brain function, primarily among non-Hispanic white females with adequate vitamin D status, underscoring the interdependence of the two nutrients.”
“Insulin resistance in the brain is implicated in Alzheimer’s disease and is one reason why some researchers refer to the condition as “Type 3 diabetes.” Melatonin has been shown to enhance beta-cell function (the beta-cells are insulin-producing cells in the pancreas) and reduce the burden of beta-amyloid plaques and tau hyperphosphorylation in the brain of diabetic rats.”
“In a recent double-blind placebo-controlled trial involving 27 healthy older adults (average age, 62 years) with at least one risk factor for diabetes, each of the study participants engaged in three 45-minute aerobic exercise training sessions per week for 12 weeks using a treadmill, stationary cycle, or elliptical machine.”
