Whereas antioxidant exercise is an ever-vital (and legitimate) function of wholesome growing old, selling mobile integrity and defending our genes is the opposite vital a part of the longevity equation. One correct means to take a look at the rate of cellular aging and overall longevity is by measuring telomeres.
Telomeres are sequences of proteins that basically “cap” the ends of DNA strands. They shield our DNA from free radicals, trendy toxins, and different potential stressors that may have an effect on our genomic stability. In terms of longevity, longer telomeres assist shield DNA and buffer oxidative stress.
In different phrases, telomere size (once more, longer is healthier) is a viable biomarker for longevity—and vitamin D performs an element in rising the exercise of the telomerase enzyme to maintain telomere length and strength and shield mobile DNA and cells’ capability to copy.*
In truth, a 2017 study from the Archives of Medical Science discovered a optimistic affiliation between vitamin D sufficiency and telomere size, which signifies getting enough vitamin D is important for maintaining genomic integrity and thus, longevity potential.*
