A 12-month randomized controlled trial found that vitamin D supplementation improved cognitive function, intelligence quotient scores, telomere length, and lowered oxidative stress markers in older adults (compared to placebo).
The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
And lastly, vitamin D also decreases oxidative stress. It's been shown in the the mild cognitive impairment trial that I mentioned earlier. This was a randomized control trial. Those individuals that took vitamin D also had decreased levels of various markers of oxidative stress compared to people that were given the placebo.
