“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Dr. Patrick discusses paraquat and rotenone because both can damage mitochondria and are used experimentally to model Parkinson-like neurodegeneration, but that rationale does not prove that either chemical caused disease in this population.”

“A systematic review found no overall improvement in mood after cold-water immersion, while a small randomized trial found that repeated whole-body cryotherapy improved depression scores when added to standard pharmacological treatment.”

“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.”

“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.”

“Mouse studies of feeding during infection also found different responses across bacterial and viral models, so a minimally processed dietary pattern, regular exercise, and normal hydration and nutrition during illness provide a more useful foundation than one universal food or fasting rule.”

“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 a small trial of 30 people with stable heart failure, 1,000 milligrams twice daily approximately doubled whole-blood NAD and appeared tolerable while supporting further study rather than proving treatment benefit.”

“Reversing the Cardiac Effects of Sedentary Aging in Middle Age—A Randomized Controlled Trial - In sedentary middle-aged adults, 2 years of regular exercise improved heart function and reduced heart stiffness, potentially lowering future heart failure risk.”

“00:29:20 - Organs shrink during fasting and then regrow after refeeding. Study. 00:29:45 - Fasting stresses healthy cells so they increase their stress-response pathways, including heat shock proteins, antioxidant production, and anti-inflammatory.”
