“A 12-month randomized trial in 210 adults with Alzheimer's disease found improvements in selected cognitive scores and amyloid-related blood markers with 800 IU daily. Together, these findings support measuring status and correcting deficiency with individualized guidance rather than assuming one dose fits everyone.”

“In older adults with mild cognitive impairment, higher-flavanol cocoa improved selected verbal-fluency and executive-function tests over eight weeks. These small, population-specific studies do not establish broad disease prevention or cognitive benefit for everyone.”

“More Specific Options NOVOS Age - an at-home blood test centered on DunedinPACE, organ-age algorithms, biological age, and telomere length. Best fit for viewers most interested in the pace-of-aging and organ-age parts of the conversation.”

“Acutely, Nam had the strongest transient effect on the whole‐blood NAD metabolome, consistent with fast absorption/metabolism. Ex vivo fermentation suggested NR and NMN generate nicotinic acid (NA) and selectively enhance microbial growth/metabolism.”

“She reviews possible adverse effects such as morning grogginess, daytime sleepiness, headache, and feeling cold or developing hypothermia. Melatonin can interact with blood thinners and other prescription drugs, so dose and timing require clinical review when these apply.”

“Clinically, this issue can become apparent through symptoms such as insufficient gonadal development during adolescence or abnormal patterns on blood tests, and reflect the body's struggle to achieve adequate androgenic effects.”

“Dr. Levine cautions that tests based on the early versions of epigenetic clocks are inherently flawed – full of statistical noise and unexplained variability. However, tests based on later-generation clocks, such as the DNAm PhenoAge or DNAm GrimAge clocks, says Dr. Levine, account for that noise and are more reliable.”

“Vitamin D status is commonly assessed with serum 25-hydroxyvitamin D, but the same supplement dose can produce very different blood levels. In this clip from Dr. Rhonda Patrick's appearance on The Tim Ferriss Show, she describes how baseline status, body size, genetics, sun exposure, and supplement content can contribute to that variation.”

“EPA and DHA come directly from marine foods such as fish, while alpha-linolenic acid comes from foods such as walnuts, flaxseeds, and chia seeds. The Omega-3 Index measures EPA and DHA in red-blood-cell membranes as a longer-term marker of status.”

“00:16:53 - What the power of the placebo effect teaches us about how thinking and emotions can influence the quality of our lives. 00:19:17 - Early detection tests, like the "annual digital upload" (a full-body MRI) and GRAIL (a comprehensive cancer screening blood test).”
