#112 How To Slow Biological Aging With a Multivitamin, Vegetables, & Omega-3 | Dr. Steve Horvath
In this episode, host Dr. Rhonda Patrick engages with Dr. Steve Horvath, a pioneer in longevity science and the developer of the Horvath epigenetic clock. The discussion centers on how biological aging—once a vague concept related to frailty or the passage of time—has been transformed into a quantifiable metric through DNA methylation. The conversation clarifies that biological age is not a single, monolithic number. Dr. Horvath explains that different epigenetic clocks serve distinct purposes; some are more sensitive to metabolic health and inflammation, while others are superior predictors of mortality risk. They discuss the nuances of key clocks like GrimAge and DunedinPACE, noting that while these tools are powerful for understanding how lifestyle interventions—such as exercise, diet, and sleep—impact the aging process, they are not absolute crystal balls or death-date calculators. The episode also tackles provocative questions regarding whether caloric restriction, specific supplements like Omega-3s, or pharmaceutical interventions can truly reverse epigenetic aging. Dr. Horvath emphasizes the importance of scientific precision, warning that while a clock might move in a favorable direction, it does not necessarily equate to total systemic rejuvenation. The episode provides a comprehensive look at what is currently measurable, modifiable, and understood in the quest to slow biological aging.
