The Claim

Vitamin D supplementation at 2,000 IU/day combined with a home exercise program of 30 minutes three times per week has no significant effect on any of the four epigenetic aging clocks—PhenoAge, GrimAge, GrimAge2, and DunedinPACE—over a three-year period in healthy older adults.

Description
1 study reviewed
In plain English

Taking vitamin D pills and doing light exercise at home three times a week for three years doesn't seem to slow down or speed up how fast your body ages at the molecular level, based on four different aging tests.

See the scientific wording

Vitamin D supplementation (2,000 IU/day) and a home exercise program (30 minutes, three times per week) show no significant effect on any of the four epigenetic aging clocks (PhenoAge, GrimAge, GrimAge2, DunedinPACE) over three years in healthy older adults, suggesting these interventions alone do not meaningfully alter molecular aging trajectories.

What the research says

1 study

  1. Study: Individual and additive effects of vitamin D, omega-3 and exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

    The study found that taking vitamin D and doing exercise alone didn’t slow aging much, but when combined with fish oil, they helped a little. So saying they do nothing is not quite right—they just need help from something else.
