Harvard just dropped a study showing that popping a daily vitamin D pill could actually slow down aging—like, for real. They found people over 50 who took 2,000 IU of vitamin D daily had way less telomere shortening (that’s the thing that makes your cells age) than those who didn’t. Bonus: fewer autoimmune issues and less inflammation, too. The catch? Docs still say don’t go overboard—more isn’t always better. But maybe check your cereal box for that D! #Health #Diet #VitaminD
