“Timing provides a practical compromise. Dr. van Loon favors protecting the first several hours after resistance or endurance training, then placing cold exposure later in the day or on a recovery day when muscle adaptation is the priority.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”

“Perhaps the most clear-cut examples of cryotherapy’s beneficial effects are observed in the brain, where levels of the hormone and neurotransmitter norepinephrine – responsible for vigilance, attention, focus, and positive mood – increase markedly when the body is exposed to extreme cold.”

“The majority of glutamine administered orally is taken up by the liver and gut, with little ending up in the bloodstream.

“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.”

“Creatine works by building tissue stores, so consistent daily intake matters more than taking it immediately before a specific workout. Dr. Patrick and Dr. Candow also discuss its value during aging, when preserving training quality and muscle becomes increasingly important for function and independence.”
