Q: I\u2019ve seen several posts online claiming that vitamin D can reverse aging. Is that true?\n<\/p>\n

If you’re deficient in vitamin D, then vitamin D might be able to slow certain aging processes. But if you already have sufficient levels, there’s no strong evidence that extra vitamin D will reverse or slow aging.\n<\/p>\n

For instance, you need vitamin D for collagen and elastin production. If you have insufficient levels, you’ll probably see more skin aging.\n<\/p>\n

One of the hallmarks of aging is telomere length. Telomeres are protective caps on the ends of your chromosomes. Every time a cell divides, the telomere shortens. \u00a0\n<\/p>\n

As we age, telomeres become shorter, and we see more errors and mutations in DNA. If you can keep telomeres long, you\u2019re less likely to see DNA damage and aging outcomes.\n<\/p>\n

There are certain things that may accelerate telomere shortening, like sleep deprivation, stress, pollution, eating a processed diet, and not exercising. Then there are habits like resistance training and other exercises that can slow down telomere shortening over time.\n<\/p>\n

In a study published in July, researchers tested the white blood cells of more than 900 people enrolled in a larger clinical trial on vitamin D and omega-3 supplementation. Half the participants took 2,000 IU of vitamin D3 daily.\n<\/p>\n

The group that took the supplements lost 140 fewer DNA base pairs, which reduces the risk of errors and mutations that can lead to cell dysfunction. People who took vitamin D supplements also had longer telomeres. That\u2019s why some people are hypothesizing that vitamin D can slow aging.<\/p>\n

Telomere shortening is just one of 12 proposed mechanisms of aging. All potential mechanisms have strengths and weaknesses, and scientists don\u2019t agree on what drives aging.<\/p>\n
