Vitamin D supplementation may delay biological aging 🧬
Massive finding for the importance of vitamin D.
Vitamin D3 and marine ω-3 fatty acids supplementation and leukocyte telomere length: 4-year findings from the VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial
Study Details
This new study investigated the effects of 2000 IU/day vitamin D3 in 1,054 adults aged 50+ years over a 4-year period 🔍
Specifically focusing on telomere length outcomes 🔬
Telomeres are protective DNA sequences, their shortening is closely linked to…
⏰ Advanced aging
🦠 Increased susceptibility to chronic diseases
Here is what they found ⬇️
Key Findings
Compared to placebo, vitamin D3 supplementation significantly…
…decreased leukocytes telomere (LTL) attrition by 0.14 kilo base pairs (kb) over 4 years ⏳
Overall trend analysis showed that the vitamin D3 group had LTLs that were about 0.035 kb higher per year of follow-up vs the placebo group 📊
The study also investigated the effects of 1 g/day omega-3 but this had no impact on telomeres ❌
Conclusion
Vitamin D supplementation to maintain serum levels of 100 - 150 nmol/L may be able to delay biological aging ✅
