Abstract: Researchers discovered vital cognitive advantages for older adults who took each day multivitamin-mineral dietary supplements.

Alzheimer’s & Dementia: The Journal of the Alzheimer’s Affiliation has revealed “Results of cocoa extract and a multivitamin on cognitive perform: a randomized medical trial.”
The three-year examine of greater than 2,200 older adults discovered that each day multivitamin-mineral supplementation resulted in a statistically vital cognitive profit.
Cocoa extract had no impact on world cognition.
Maria C. Carrillo, Ph.D., Alzheimer’s Affiliation chief science officer, mentioned of the examine: “That is the primary optimistic, large-scale, long-term examine to point out that multivitamin-mineral supplementation for older adults might sluggish cognitive growing older. Whereas the Alzheimer’s Affiliation is inspired by these outcomes, we’re not able to advocate widespread use of a multivitamin complement to cut back threat of cognitive decline in older adults.”
“Impartial confirmatory research are wanted in bigger, extra numerous examine populations. It’s crucial that future remedies and preventions are efficient in all populations.”
“For now, and till there’s extra knowledge, individuals ought to speak with their well being care suppliers about the advantages and dangers of all dietary dietary supplements, together with multivitamins.”
“We envision a future the place there are a number of remedies and threat discount methods obtainable that handle cognitive growing older and dementia in a number of methods — like coronary heart illness and most cancers — and that may be mixed into highly effective mixture therapies… at the side of brain-healthy tips for life-style elements like weight loss plan and bodily exercise.”

Results of cocoa extract and a multivitamin on cognitive perform: A randomized medical trial
Introduction
Dietary dietary supplements are touted for cognitive safety, however supporting proof is combined. COSMOS-Thoughts examined whether or not each day administration of cocoa extract (containing 500 mg/day flavanols) versus placebo and a industrial multivitamin-mineral (MVM) versus placebo improved cognition in older men and women.
Strategies
COSMOS-Thoughts, a big randomized two-by-two factorial 3-year trial, assessed cognition by phone at baseline and yearly. The first consequence was a worldwide cognition composite shaped from imply standardized (z) scores (relative to baseline) from particular person checks, together with the Phone Interview of Cognitive Standing, Phrase Checklist and Story Recall, Oral Path-Making, Verbal Fluency, Quantity Span, and Digit Ordering. Utilizing intention-to-treat, the first endpoint was change on this composite with 3 years of cocoa extract use. The pre-specified secondary endpoint was change within the composite with 3 years of MVM supplementation. Remedy results had been additionally examined for govt perform and reminiscence composite scores, and in pre-specified subgroups at larger threat for cognitive decline.
Outcomes
A complete of 2262 contributors had been enrolled (imply age = 73y; 60% girls; 89% non-Hispanic White), and 92% accomplished the baseline and a minimum of one annual evaluation. Cocoa extract had no impact on world cognition (imply z-score = 0.03, 95% CI: -0.02 to 0.08; P = .28). Every day MVM supplementation, relative to placebo, resulted in a statistically vital profit on world cognition (imply z = 0.07, 95% CI 0.02 to 0.12; P = .007), and this impact was most pronounced in contributors with a historical past of heart problems (no historical past: 0.06, 95% CI 0.01 to 0.11; historical past: 0.14, 95% CI -0.02 to 0.31; interplay, nominal P = .01). Multivitamin-mineral advantages had been additionally noticed for reminiscence and govt perform. The cocoa extract by MVM group interplay was not vital for any of the cognitive composites.
Dialogue
Cocoa extract didn’t profit cognition. Nevertheless, COSMOS-Thoughts gives the primary proof from a big, long-term, pragmatic trial to assist the potential efficacy of a MVM to enhance cognition in older adults. Extra work is required to substantiate these findings in a extra numerous cohort and to determine mechanisms to account for MVM results.
