The Claim
Genetically predicted higher circulating vitamin D levels are associated with a modest increase in adult height, such that 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 lifelong vitamin D exposure in skeletal growth.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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—because their bodies have had more vitamin D throughout life.

What the research says
1 studyThe study used Mendelian randomization with genetic variants as proxies for lifelong vitamin D exposure, showing a consistent positive association across multiple MR methods (IVW, weighted median, weighted mode) with no evidence of pleiotropy, supporting a directional causal link from vitamin D to height.
