How To Slow Biological Aging With a Multivitamin, Vegetables, & Omega-3 | Dr. Steve Horvath

Dr. Steve Horvath, creator of the epigenetic clock, joins Dr. Rhonda Patrick to discuss how biological age is measured and how it can be influenced. He explains why clocks like GrimAge and DunedinPACE are powerful predictors of mortality and aging speed, and which are best suited for testing anti-aging interventions. Horvath highlights the strongest evidence to date: omega-3 fatty acids, a daily multivitamin, and adequate vegetable intake can each slow epigenetic aging, with some studies showing up to five years of reversal in months.

Novel

A Daily Multivitamin May Slow Epigenetic Aging01:17:29
Horvath cites randomized controlled trial evidence showing that a daily multivitamin can slow or even reverse epigenetic age as measured by several clocks over a multi-year period.
Vegetable Intake May Rival Exercise for Epigenetic Age Reduction01:36:29
Horvath presents data suggesting that eating more vegetables can reduce epigenetic age comparably to the benefits seen with regular exercise.

Highlights

GrimAge Accurately Predicts Mortality Risk00:24:10
Horvath explains that GrimAge, a methylation clock, is a powerful predictor of all-cause mortality, outperforming many traditional risk factors.
Omega-3, Vitamin D, and Exercise: Which Slows Aging Best?01:26:11
When comparing three commonly studied anti-aging interventions, Horvath finds that omega-3 fatty acids have the most consistent evidence for slowing epigenetic aging, followed by exercise.
Long-Term Stress Leaves an Epigenetic Signature00:24:10
The epigenome can 'remember' chronic stress through persistent changes in DNA methylation, which may accelerate biological aging.
