Related Episodes for What COSMOS Found About Multivitamins and Cognition

“Earlier long-term research in older male physicians found no cognitive benefit, and the main COSMOS trial did not significantly reduce invasive cancer, cardiovascular events, or mortality over a median of 3.6 years.”

“In this clip from Dr. Rhonda Patrick's appearance on The Tim Ferriss Show, she describes the supplements her parents use and separates a simple nutritional baseline from choices tied to individual health needs.”

“She highlights its roles in brain health and homocysteine metabolism. Product quality matters for omega-3 supplements because these fats oxidize readily; she favors products with third-party testing for oxidation and labeled EPA and DHA content, with algal oil as a vegan option.”

“However, she considers the amounts in its proprietary superfood, extract, and probiotic blends too small to justify expecting the broader benefits implied by those categories. She presents this as her assessment of the product label.”

“Dr. Patrick uses 4,000 IU of vitamin D as a reference point, which is also the adult tolerable upper intake level, and takes 250 milligrams of supplemental magnesium as her personal dose while emphasizing magnesium-rich foods.”

“Magnesium supports hundreds of enzyme reactions involved in functions such as energy metabolism and DNA repair, and foods including leafy greens, legumes, nuts, seeds, and whole grains can help close common intake gaps.”

“In a crossover study of 15 healthy adults, a single 0.35-gram-per-kilogram dose during acute sleep deprivation changed brain-energy metabolites and improved selected cognitive tasks.”

“Sulforaphane activates NRF2-regulated cellular defense pathways. In a randomized crossover trial of 60 adults, eating 85 grams of raw watercress daily for eight weeks reduced basal lymphocyte DNA damage by 17% and oxidative purine DNA damage by 23.9%.”

“Independent finished-product testing can verify identity and selected contaminants, while diet, laboratory results, medicines, kidney health, age, and life stage can guide decisions about iron, vitamin D, omega-3, and magnesium.”

“A pooled analysis estimated effects of about 0.07 standard deviation for global cognition and 0.06 for episodic memory, providing evidence that a standard multivitamin can support selected cognitive outcomes in some older adults.”
