Vitamin D3 and marine ω-3 fatty acids supplementation and leukocyte telomere length
-
Telomere shortening is associated with aging. Unsurprisingly, sSunshinre helps. Marine ω-3 fatty acids don't.
Results: LTL was measured in a total of 2,571 samples from the 1031 participants at baseline, year 2, and year 4. Compared to placebo, vitamin D3 supplementation significantly decreased LTL attrition by 0.14 kilo base pairs (kb) (95%CI: 0.007, 0.27) over 4 years (p = 0.039). Overall trend analysis showed that the vitamin D3 supplementation group had LTLs that were about 0.035 kb higher per year of follow-up compared to placebo group (95%CI: 0.002, 0.07, p=0.037). Marine n-3 FAs supplementation had no significant effect on LTL at either year 2 or year 4.
