The Claim

Genetically predicted higher circulating vitamin D levels are associated with a modest increase in adult height, where each standard deviation increase in vitamin D corresponds to a 0.046 standard deviation increase in height, indicating a small but statistically significant role for vitamin D in linear growth during development.

In plain English

People who naturally have more vitamin D in their blood tend to be a tiny bit taller as adults—like a small nudge in height—not much, but it’s a real pattern scientists noticed.

What the research says

1 study

  1. Study: Causal relationship between vitamin D and adult height: A bidirectional Mendelian randomization study

    Scientists used genes to predict vitamin D levels and found that people with naturally higher vitamin D tended to be slightly taller, proving vitamin D helps growth — not the other way around.
