Vitamin B3: Keeping Your Heart and Brain Healthy.

At these doses, they must be treated as drugs not just any dietary supplement, and should not be taken without medical advice as there could be side effects. The researchers held a press briefing in London communicating their excitement at these results but stressing all these points.

Trends identified in their report suggest that the treatment could slow deterioration of cognition, but this was not demonstrated directly in this small study. Instead, it sets out important questions for further study and gives new confidence that effective treatments modifying the course of some dementias may be in sight.

These include comparison of observed effects to natural atrophy by age and the actual relationship between cognitive ability and the use of B vitamins.

As to the latter of these, there is no direct analysis of cognition and whilst it is alluded to, the lack of this is a clear limitation. But it is important to note that the study is rather small and needs replicating in a larger study. However, we must be cautious when recommending supplements like vitamin B as there are separate health risks if taken in too high doses.

Figure 1 in the paper outlines the flow of participants through the two-year study. Drop out numbers at each stage are given with some of the reasons. There are some who drop out before the trial, some during, some were excluded, some were diagnosed with cancer, and two died.

Of the initial participants, completed the two-year trial and cognitive tests. Cohort studies investigating dietary intake of B vitamins and the risk of incident dementia were eligible.

Cross-sectional studies comparing differences in levels of B vitamins and Hcy were included. Data extraction: Two reviewers independently performed data extraction and assessed the study quality.

Data analysis: Random-effect or fixed-effect models, depending on the degree of heterogeneity, were performed to calculate mean differences MDs , hazard ratios HRs , and odds ratios ORs.

Results: A total of 95 studies with participants 25 RCTs, 20 cohort studies, and 50 cross-sectional studies were included in this meta-analysis.

This meta-analysis supports that B vitamins can benefit cognitive function as measured by Mini-Mental State Examination score changes participants; MD, 0. In the non-dementia population, B vitamin supplementation slowed cognitive decline participants; MD, 0.

Lower folate levels but not B12 or B6 deficiency and higher Hcy levels were significantly associated with higher risks of dementia folate: participants; OR, 1. The two-year study was published in the New England Journal of Medicine in In another study, published in the Lancet in , Dutch researchers randomly assigned more than older adults to take either high doses of those same B vitamins or a placebo every day for three years.

In this case, the group that took the B vitamins not only experienced a drop in homocysteine levels but also performed better on tests of memory and information processing.

But a third study, published in the Journal of the American Medical Assn. The review excluded vitamin B6. Haan says the existing body of studies may be inconclusive because the causes of cognitive decline — which are incompletely understood — are probably too complex to be halted with a single vitamin supplement.

Brain shrinkage occurred at a rate of about 0. Adults need at least to micrograms of folic acid, 2. Amounts in these brain studies were greater than that — as much as 1, micrograms of folic acid, micrograms of vitamin B12 and up to 20 milligrams of vitamin B6.

Such high doses can have negative side effects: Too much B6 can cause numbness and insensitivity in the hands and feet, and too much folic acid may confusingly either mask or exacerbate symptoms of vitamin B12 deficiency.

To some, tingling in the extremities may seem a fair price to pay for the possibility of delaying cognitive decline. De Los. En Español.
