Vitamin D May Slow Aging, Study Suggests
Researchers are studying if vitamin D supplements can help slow down how quickly we age.
They found that people taking vitamin D had less shortening of their telomeres, which are like protective caps on our DNA that get shorter as we age.
By keeping these caps longer, vitamin D may help with healthy aging.
It's important to eat well, live healthily, and not rely solely on supplements for health.
You can get vitamin D from sunlight, fish, and some fortified foods.
Study indicates that vitamin D intake may slow aging.
The study looked at the relationship between vitamin D and telomere length.
Telomeres shorten with age.
Vitamin D supplements were associated with reduced telomere shortening.
Experts suggest a focus on diet and lifestyle instead of solely relying on supplements.
