“Gut cells and activated immune cells can use glutamine as fuel, while its conversion to glutamate and alpha-ketoglutarate connects it with cellular energy metabolism. Dr. Patrick describes her own daily use of glutamine and her experience of fewer minor respiratory illnesses after becoming a parent.”

“The available randomized trials support tolerability for up to four months in selected adults, not indefinite use. A small 28-day trial also found changes in immune-cell composition and metabolism, but it did not test infections, vaccine responses, or clinical immune rejuvenation.”

“Easy or moderate movement may be appropriate after a mildly short night, while severe sleepiness is a reason to reduce training demands and prioritize rest. This clip is excerpted, with permission, from Dr. Rhonda Patrick's appearance on Huberman Lab.”

“Heat stress activates molecular chaperones that help fold damaged proteins and maintain proteostasis, while heat therapy may also influence vascular and metabolic pathways relevant to cognitive aging. A prospective Finnish study followed 2,315 middle-aged men for a median of 20.7 years.”

“In 27 men with metabolic syndrome, four four-minute intervals near 90 percent of peak heart rate improved VO2 max more than work-matched moderate exercise. A two-year randomized trial used a broader progressive program in healthy, sedentary adults around age 53.”

“Nine months later, another group of eight men took part in the same process, but they ate whenever they wanted to, but their caloric intake was matched to that of what the men ate during the time-restricted eating period (which was about 400 calories per day lower than usual due to the limited time frame in which they ate).”

“These findings suggest a potential shift in how the body produces and uses energy. Signals of altered carbohydrate metabolism suggest that the body may rely less on glucose for energy. In response, the body may rely more on fat and amino acids as energy sources.”

“Click here to view our nearly 30-page, 190 reference overview article on vitamin C. Bioavailability of vitamin C The absorption, distribution, metabolism, and excretion of vitamin C are complex and differ considerably from other low molecular weight compounds.”

“FTA: > Losing as little as 30 minutes of sleep per day on weekdays can have long-term consequences for body weight and metabolism, a new study finds.”

“However, engaging in 15 or more MET-hours per week of physical activity appeared to offset the harmful effects of long sleep duration, difficulty falling asleep, or using sleeping pills. Engaging in 30 or more MET-hours per week provided even more robust protection, effectively canceling out the harmful effects.”
