The Claim

The combination of omega-3 supplementation, vitamin D (2,000 IU/day), and a home exercise program (30 minutes, three times per week) produces an additive effect in slowing PhenoAge-based biological aging by up to 0.32 standardized units (3.8 months) over three years in healthy older adults.

In plain English

Taking omega-3 supplements, vitamin D pills, and doing light exercise at home three times a week for three years might slow down how fast your body ages—by about 3.8 months—compared to not doing any of these things.

  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

    This study found that taking omega-3 pills, vitamin D, and doing light exercise three times a week for three years helped slow down biological aging in older adults — just like the claim says. The combination worked better than any one alone.
