Large study finds that placebo works as well as vitamin D supplements to prevent depression and improve mood

August 6, 2020 by Alvaro Fernandez

Large Study Con­firms Vit­a­min D Does Not Reduce Risk of Depres­sion in Adults (Mass Gen­er­al press release):

Vit­a­min D sup­ple­men­ta­tion does not pro­tect against depres­sion in mid­dle-age or old­er adult­hood accord­ing results from one of the largest ever stud­ies of its kind … “There was no sig­nif­i­cant ben­e­fit from the sup­ple­ment for this pur­pose. It did not pre­vent depres­sion or improve mood,” says Olivia I. Okereke, MD, MS, of the Mass­a­chu­setts Gen­er­al Hos­pi­tal (MGH) Psy­chi­a­try Department.

Vitamin D and Cognitive Decline: What’s the Relationship?

February 1, 2011 by Dr. Pascale Michelon

The role of vit­a­min D in the brain appeared evi­dent in the 1980s when researchers found key pro­teins in the brain involved in vit­a­min D metab­o­lism. A lot of clin­i­cal evi­dence has accu­mu­lat­ed since then sug­gest­ing that low vit­a­min D lev­els may poten­tial­ly result in cog­ni­tive decline. Nonethe­less the results are mixed and not all pre­vi­ous stud­ies have show that low lev­els of vit­a­min D are indeed asso­ci­at­ed with cog­ni­tive decline or dementia.

A 2010 study eval­u­at­ed this ques­tion for the first time by fol­low­ing the same indi­vid­u­als over the years, instead of com­par­ing peo­ple with nor­mal lev­els and peo­ple with low-lev­els of vit­a­min D. This study fol­lowed 858 adults 65 years and old­er over 6‑years. Results showed an increased risk of cog­ni­tive decline in patients with vit­a­min D defi­cien­cy.
