Dr. Rhonda Patrick answers audience questions on various health, nutrition, and science topics in this Q&A session.

“Animal studies indicate that omega-3 deficiency may also reduce GLUT1 transporters in the brain. Other studies suggest that omega-3 supplementation reduces VCAM1 levels – a protein elevated with normal aging, which could be related to the breakdown of the blood-brain barrier.”

“Five grams of creatine per day increased total sleep duration on resistance-training days compared with placebo, while the groups did not differ in overall sleep quality. The result introduces sleep as a promising new area of creatine research.”

“Dr. Patrick explains that omega-3 fatty acids may help preserve muscle during periods of immobilization, illness, or injury, while Brady Holmer describes creatine as a practical daily tool for training capacity, strength, and recovery.”

“Dr. Patrick also describes a trial in vitamin-D-deficient, overweight African-American adults in which 4,000 IU per day reduced an epigenetic-age measure by almost two years. Epigenetic age is a surrogate biomarker, not proof that vitamin D slowed clinical aging, prevented disease, or extended life.”

Dr. Rhonda Patrick discusses organic produce, fasting-mimicking diets, sleep, sauna, sunscreens, red light therapy, reverse osmosis water, and fiber.

“Dr. D'Agostino asserts that a low carbohydrate diet incorporating intermittent fasting probably has more benefits than chronic ketosis for most healthy adults. Drs. D'Agostino and Patrick describe their experiences with fasting or time-restricted eating and its calming effects on the brain.”

Drs. Levine and Patrick discuss how and why individuals age at different rates and how menopause & obesity may increase an individual's rate of aging.

“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.”

“Dr. Patrick also distinguishes general-population evidence from people with diabetes or insulin resistance, where some observational studies report different risk patterns and residual confounding remains substantial.”
