“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.”

“A 2023 review concluded that, compared to regular caffeinated coffee, Bulletproof coffee didn't improve cognition, alertness, or energy levels and the effects on hunger, satiety, and metabolism were equally as unimpressive.”

“For example, exposure to ultraviolet B light is the primary source of vitamin D, but behaviors or characteristics that block or reduce sun exposure, such as using sunscreen, having high levels of melanin (a dark pigment found in skin that acts like natural sunscreen), exclusive breastfeeding, older age, or being obese can impair the skin's ability to produce vitamin D3.”

“Across three COSMOS cognitive substudies using different testing formats, a pooled analysis found small average advantages for global cognition and episodic memory over two to three years—about 0.07 and 0.06 standard deviations, respectively.”

“Some animal evidence suggests that magnesium threonate readily crosses the blood-brain barrier and, at human-equivalent doses of 8.1 milligrams per kilogram body weight (roughly 662 milligrams for a 180-pound person), can improve cognition and decrease amyloid plaques in the brain.”

“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.”

“Our brains shrink as we grow older, but that doesn't mean you can wait until old age to worry about it—neurodegeneration starts 15–20 years before the onset of symptoms of mild cognitive impairment, dementia, or Alzheimer's disease.”

“In addition, a randomized, placebo-controlled, double-blind trial involving people diagnosed with mild-to-moderate dementia due to Alzheimer's disease found that participants who took a resveratrol supplement twice a day (up to 1 gram) for one year exhibited reduced levels of MMP9, a neurological inflammatory marker associated with increased neurodegeneration and inflammation.”

“Regardless of sex, genetic risk, or baseline cognition, the evidence is clear: Vitamin D is a powerful ally in reducing dementia risk. Though dosage details and optimal blood levels remain unknown, the link between vitamin D and brain health is too significant to ignore.”

“Nutrition may offer additional support. Across three randomized COSMOS cognitive studies, a daily multivitamin produced modest average improvements in global cognition and episodic memory in older adults.”
