Whereas earlier small-scale research supplied combined outcomes, the VITAL Telomere sub-study stands out because of its measurement and rigor. It adopted 1,054 individuals aged 50 and older over 4 years, evaluating those that took 2,000 IU of Vitamin D3 day by day (a excessive dosage normally advisable for these with deficiency) with those that took a placebo.
