Here’s a list of studies about vitamin D and longevity:

Serum 25-Hydroxyvitamin D Has a Modest Positive Association with Leukocyte Telomere Length in Middle-Aged US Adults (2017)

Conclusion: A study of 4,260 adults found that those with higher vitamin D levels also had longer telomeres.


The Association of Telomere Length and Serum 25-Hydroxyvitamin D Levels in US Adults: The National Health and Nutrition Examination Survey (2017)

Conclusion: A study of 4,347 American adults found that those with higher vitamin D levels also had longer telomeres.


Relationship Between Plasma 25-Hydroxyvitamin D and Leucocyte Telomere Length by Sex and Race in a US Study (2016)

Conclusion: In a study of 1,154 older adults, vitamin D-deficient white people were found to have shorter telomeres.


Cell Defenses and the Sunshine Vitamin (2016)

Note: This article provides an overview of all the genes and processes vitamin D is involved in your body, including prevention of a wide variety of diseases.


Low Vitamin D Levels Predict Clinical Features of Schizophrenia (2014)

Conclusion: In this study investigating the correlation between vitamin D levels and schizophrenia severity, it was also found that women with higher vitamin D levels also had longer telomere length – indicating that vitamin D slows down cellular aging.


Assessment of the Potential Role of Active Vitamin D Treatment in Telomere Length: A Case-Control Study in Hemodialysis Patients (2012)

Conclusion: A study of 62 hemodialysis patients found that those receiving vitamin D treatment had longer telomeres compared to hemodialysis patients not receiving vitamin D treatment.


Increased Telomerase Activity and Vitamin D Supplementation in Overweight African Americans (2012)

Conclusion: A 4-month double-blind randomized placebo-controlled trial of 37 obese black adults found that those given vitamin D supplementation experienced a significant increase in telomerase activity, suggesting that vitamin D “may improve telomere maintenance and prevent cell senescence and counteract obesity-induced acceleration of cellular aging.”


25-Hydroxyl Vitamin D Levels and the Risk of Mortality in the General Population (2008)

Conclusion: This study followed and the tested the vitamin D levels of 13,331 adults for a period of 6-12 years. In a controlled analysis, those in the lowest vitamin D level quartile were found to have a 26% increased rate of all-cause mortality compared to those in the highest vitamin D level quartile. In the unadjusted analysis, the mortality risk was 78% higher.


Higher Serum Vitamin D Concentrations are Associated with Longer Leukocyte Telomere Length in Women (2007)

Conclusion: A study of 2,160 women found that those with higher vitamin D levels also had longer telomeres.
