DO-HEALTH trial and its three interventions
The description presents DO-HEALTH as a large-scale clinical study in older adults. It names three interventions: vitamin D, omega-3 and exercise. The episode is said to dissect the trial's findings on how these influence biological aging. The description does not state doses, exercise type, group sizes or how long participants were followed.

DNA methylation clocks as the measured outcome
According to the description, the outcome examined is biological aging measured with DNA methylation clocks. The cited publication title refers to individual and additive effects of the three interventions on these clocks. The description does not report the direction, size or statistical significance of any effect, so no benefit can be assumed from it.
