“High energy demand is a promising research setting. In a randomized crossover study of 15 healthy adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed cerebral energy measures and improved selected cognitive outcomes.”

“A single 0.35-gram-per-kilogram dose of creatine monohydrate, equal to 24.5 grams for a 70-kilogram adult, reduced fatigue and improved word memory and processing speed on selected tasks versus placebo. It also changed brain-energy measures.”

“A later crossover study using a lower weight-based dose found its clearest benefit in reasoning, while several memory, accuracy, fatigue, and sleepiness outcomes did not reliably improve. Routine muscle supplementation and acute sleep-loss research use different protocols.”

“In another randomized trial, advice to drink an additional 1.5 liters of water daily improved migraine-specific quality of life, even though headache-day counts did not clearly change. Selected nutrients may help some people as part of a broader prevention plan.”

“A systematic review in older adults linked Mediterranean dietary patterns with lower inflammatory markers, while a meta-analysis of randomized trials found that vitamin D supplementation reduced acute respiratory infection risk overall, with the strongest protection among people who were very deficient and received regular doses.”

“This is a proposed metabolic advantage, not proof of slower brain aging. Small TBI trials found that sodium lactate lowered intracranial pressure more than mannitol in severe TBI and improved cognitive scores more than 3% sodium chloride in mild TBI.”

“She uses that result to make consistency practical. Aerobic exercise does not need to be all-out every day, but sessions that raise heart rate and improve cardiorespiratory fitness provide a meaningful brain stimulus.”

“In 15 people with severe traumatic brain injury, sodium lactate infusion increased brain lactate, pyruvate, and glucose without raising intracranial pressure, and a randomized study in 60 patients with mild traumatic brain injury reported better cognitive recovery than hypertonic saline.”

“A small randomized trial in trained athletes found that 20 milligrams per day for two weeks increased total antioxidant capacity and glutathione peroxidase and reduced post-training DNA damage versus placebo; it did not test performance or long-term adaptation.”

“In the prospective Framingham Offspring Study, people in the highest red-blood-cell DHA group had approximately 49 percent lower risk of developing Alzheimer's disease than those in the lowest group.”
