Harvard Study: Vitamin D May Slow Ageing Process
A new study from Harvard suggests a common vitamin might help you stay young longer.
Researchers found that taking vitamin D3 daily may slow down the aging process by protecting parts of our cells called telomeres.
Telomeres are like the caps on the ends of shoelaces that protect our DNA.
They shorten as we get older, and this can lead to health problems.
The study showed that people who took vitamin D3 daily for four years had less telomere shortening compared to those who did not.
Experts believe vitamin D might help by reducing inflammation or helping rebuild telomeres.
It's important to remember that more research is needed, and it's best to talk to a doctor before starting any new supplements.
A Harvard study suggests vitamin D3 may slow the aging process.
Daily intake of 2,000 IU of vitamin D3 was used in the study.
Vitamin D3 supplementation helped preserve telomere length.
Researchers found participants taking vitamin D3 had less telomere shortening.
Experts recommend consulting a healthcare professional before taking supplements.
