- Researchers conducted a study to see whether genetic predisposition to high vitamin D levels affects overall health.
- They found that genetic predisposition to higher vitamin D levels reduces all-cause mortality by 30% in people with low vitamin D levels.
- Genetic predisposition had no effect on mortality among those with higher levels of vitamin D.
- The researchers conclude that genetic evidence suggests a causal relationship between vitamin D levels and mortality only in people with low vitamin D levels.
