Vitamina D luată fără să fie nevoie, asociată cu un declin cognitiv mai rapid. Ce arată un studiu desfășurat timp de șase ani

A recent study indicates that taking vitamin D supplements without deficiency may lead to faster cognitive decline in older adults. The research followed over 5,000 participants for six years, revealing that those with adequate vitamin D levels who took supplements performed worse on cognitive tests. However, the study is observational and does not prove causation. Experts suggest that supplementation is unnecessary for those with sufficient levels, as higher doses have not shown benefits in preventing cognitive decline. The findings raise concerns about the indiscriminate use of vitamin D supplements and highlight the importance of individual assessment before supplementation.
