Deans' stroke musings: Does a Daily Multivitamin Provide a Mortality Benefit?

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Does a Daily Multivitamin Provide a Mortality Benefit?

But this?

Can a multivitamin keep your brain healthy?

A new study suggests that a daily multivitamin might improve memory in older adults.

Does a Daily Multivitamin Provide a Mortality Benefit?

Thomas L. Schwenk, MD, reviewing Loftfield E et al. JAMA Netw Open 2024 Jun Barnard ND et al. JAMA Netw Open 2024 Jun

This large cohort study showed no benefit, adding to mostly negative prior studies.

Despite mostly negative results from prior studies about mortality benefits of multivitamins, multivitamin use continues to be ubiquitous and is viewed by many patients as a cheap, safe, and easy way to improve dietary quality and health outcomes. Investigators addressed what they considered to be inadequacies of prior research by pooling data from three large observational cohort studies with nearly 400,000 participants (median age, 62) who were followed for as long as 27 years (mean, 20 years); these studies included data on diet, self-reported multivitamin use, and mortality.

In adjusted analyses, daily multivitamin use was associated with a very small, but significant (4%), higher all-cause mortality risk. Cause-specific mortality from heart disease, cancer, or cerebrovascular disease was not different in multivitamin users and nonusers.

Comment

As editorialists note, selective benefits might accrue from specific components of multivitamins, such as slowing progression of age-related macular degeneration or addressing deficiencies associated with bariatric surgery. A recent study showed some benefit from multivitamin use in slowing age-related cognitive decline (Am J Clin Nutr 2024; 119:692), although many limitations of that study have been noted. Results from the current study — casting some doubt on a mortality benefit of multivitamin use — are unlikely to change the feelings of reassurance that many patients gain. Nevertheless, we can share these findings with patients who ask us whether they should be taking daily multivitamins.
