Can Vitamin-D Supplementation Prevent Aging ?
In this study, researchers employ a quasi-interventional study design to assess the relationship between DNAmAA of five epigenetic clocks and vitamin D supplementation. Longitudinal data were available for 1,036 participants of BASE-II that were reexamined on average 7.4 years later in the GendAge study (mean age at follow-up: 75.6 years, SD=3.8 years, age range: 64.9–94.1 years, 51.9% female). Vitamin D–deficient participants who chose to start vitamin D supplementation after baseline examination showed a 2.6-year lower 7-CpG DNAmAA (p=0.011) and 1.3-year lower Horvath DNAmAA (p=0.042) compared to untreated and vitamin D–deficient participants. DNAmAA did not statistically differ between participants with successfully treated vitamin D deficiency and healthy controls (p>0.16). Therefore, they conclude that intake of vitamin D supplement is associated with lower DNAmAA in participants with vitamin D deficiency.
