“The majority of glutamine administered orally is taken up by the liver and gut, with little ending up in the bloodstream. Dr. D'Agostino discourages supplementing with glutamine for patients with cancers of the gastrointestinal tract and even recommends they avoid high glutamine containing foods.”

“In this short video, Rhonda talks about the new study and suggests that if you prefer your cruciferous veggies steamed, sautéed, or roasted, this strategy might offer a way to have your cooked vegetables and get your sulforaphane, too.”

“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.”

“00:20:21 - Some of the key blood-based biomarkers that are useful for tracking and projecting future cognitive health, including: homocysteine (<7μml/L preferred), which Dr. Bredesen indicates may be a mediator of cerebral atrophy, and also fasting insulin (<5% preferred), hemoglobin A1c, fasting glucose, vitamin D, and a number of other hormones relevant for trophic support.”
