“In this clip from Dr. Rhonda Patrick's appearance on Next Question with Katie Couric, she discusses three cognitive substudies that found small average improvements in global cognition and episodic memory.”

“Key Takeaways on Sleep Timing and Health "​​these results explain part of why one might not feel as good when they go to bed at an odd time, sleep in until noon, or eat a late-night meal—the body just isn't primed (from a chronobiological perspective) to handle this quick shift."”

“Across three randomized COSMOS cognitive studies, a daily multivitamin produced modest average improvements in global cognition and episodic memory in older adults. The global-cognition effect was statistically comparable with about two years less cognitive aging.”

“In a rodent study in which researchers provided mice DHA via diet or injection, the treated animals showed increased levels of hypothalamic neurogenesis. Similarly, a prospective interventional trial investigated the effects of omega-3s on cognition.”

“Dr. Patrick therefore favors lower-risk tools for focus, including high-quality sleep, exercise, cocoa flavanols, deliberate cold exposure, and modest caffeine, before considering an addictive stimulant. Nicotine is not equivalent to tobacco smoke, but that does not make chronic use benign.”

“Acute stress may create a different context. In a double-blind crossover study of 15 adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed brain high-energy phosphate measures and improved selected cognitive outcomes.”

“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.”

“UPFs cause metabolic and cognitive changes in less than a week "...just 5 days of a high-calorie diet made the brains of these healthy, normal weight men structurally and functionally similar to people with obesity, and even after cutting the high-calorie foods out of their diet, these changes persisted for at least one week."”

“Interestingly, repeated exposure to whole-body heat treatment through sauna use has an even more profound effect on boosting growth hormone immediately afterward: Seventeen men and women who were exposed to two one-hour sauna sessions at 80°C (176°F) dry heat (typical Finnish-style sauna) per day for seven days exhibited a 16-fold increase in growth hormone levels by the third day.”

“Extensive research indicates creatine supplementation is safe for children and adolescents. Studies consistently demonstrate improvements in muscle strength, agility, coordination, and cognition without adverse effects on growth or development.”
