“The patients saw improvements in mental examination status scores, improved cerebrospinal fluid amyloid-beta levels – a biomarker of Alzheimer's disease – and lowered cerebrospinal fluid matrix metalloproteinase 9, a mediator of neuroinflammation.”

“Omega-3 Index validation: The Omega-3 Index is a biomarker of omega-3 fatty acids in red blood cells, providing a more accurate assessment of omega-3 status and informing dietary and supplemental intake. Learn more in our article.”

“In addition, their biomarkers of mitochondrial biogenesis improved, and their mitochondrial function increased by 28 percent compared to baseline levels. This activation of HSPs is sustained over time, suggesting that heat acclimation induces whole-body adaptations that increase heat tolerance, resulting in protective cellular adaptations.”

“These findings show that nutritional and exercise interventions can influence selected aging biomarkers, although the trial's six prespecified primary clinical outcomes did not significantly improve. Cardiovascular effects also depend on the formulation and population.”

“Dr. Patrick also examines BPA and phthalates, chemicals that can interact with endocrine pathways and occur in some plastics, packaging, medical products, and personal-care products. Human studies have associated BPA biomarkers with testosterone and sperm measures, although results differ across populations.”

“DNA-methylation clocks use patterns in blood or other tissues to estimate aspects of biological aging. In this clip from Dr. Rhonda Patrick's presentation at Natural Products Expo West, she discusses how omega-3 fatty acids may influence these research biomarkers.”

“Bruce argues that while diseases of severe vitamin D deficiency like rickets are rare, the criteria for vitamin D deficiency should be based on long-term health biomarkers and not just short-term severe diseases.”

“Human trials using 500 or 1,000 milligrams per day have changed mitochondrial biomarkers and improved selected measures of muscle endurance or hamstring strength in middle-aged and older adults. Dr. Patrick describes restarting it as a personal experiment after earlier use.”

“*DNA methylation GrimAge strongly predicts lifespan and healthspan - GrimAge paper from Ake Lu, Steve Horvath, and collaborators; key background for the episode's mortality-risk caveats. *DunedinPACE, a DNA methylation biomarker of the pace of aging - useful for the pace-of-aging / "speedometer" discussion.”

“In a 20-person crossover study, endotoxin increased after a saturated-fat meal and decreased after a DHA-rich meal, while the measured inflammatory biomarkers did not differ between treatments. Together, these studies show that the response depends on the meal, dose, population, and outcome measured.”
