“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 with mild cognitive impairment (compared to placebo), suggesting that not only does vitamin D supplementation improve biomarkers of aging, but also functional outcomes.”

“In more than 25,000 adults who reported no structured exercise, about three short vigorous bouts per day were associated with 38 to 40 percent lower all-cause and cancer mortality and 48 to 49 percent lower cardiovascular mortality compared with no vigorous bouts.”
