“Longer-term nutrient status offers another perspective: in a randomized trial of adults with overweight or obesity, 15 grams of psyllium daily for three months did not significantly alter serum micronutrient concentrations relative to control.”

“For example, while vitamin C acts primarily as an antioxidant at physiological concentrations of approximately 50 micromoles per liter, pharmacologic doses of intravenous vitamin C greater than 1 gram generate hydrogen peroxide, a type of reactive oxygen species produced by neutrophils to destroy pathogens such as viruses.”

“If you have used a consumer genetic testing service like 23andMe or AncestryDNA and want to learn more about whether or not the data indicates your specific genotype on these SNPs, check out our free viral report here.”

“The most compelling human signal appears when the brain is under acute strain. In a randomized crossover study, a single dose of 0.35 grams per kilogram during 21 hours of sleep deprivation changed cerebral energy metabolites and preserved selected measures of cognitive performance.”

“A recent meta-analysis also found small benefits in selected cognitive domains, including memory and processing speed, with responses that may depend on age, diet, baseline stores, stress, dose, and the cognitive test used.”

“A separate six-week randomized study in 30 healthy young adults found that neither 10 nor 20 grams per day improved the tested cognitive outcomes compared with placebo. The result is an important counterweight to the acute sleep-deprivation experiment.”

“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.”

“Dr. Patrick then prioritizes lower-glycemic-load, less-refined foods and adequate fiber. Early time-restricted eating can help some people reduce calories and may influence selected metabolic markers, but it is not required and must still preserve protein and diet quality.”

“Translating sleep insights into practical steps These findings highlight the possibility of using heat therapy or vigorous exercise to influence slow-wave sleep, drawing on the interplay between body temperature regulation, immunity, physical activity, and hormones.”

“This effect, sometimes called the 'afterburn effect,' does have some scientific basis, according to recent podcast guest Dr. Martin Gibala. In scientific terms, it's known as EPOC or Excess Post-Exercise Oxygen Consumption.”
