A massive NIH study of nearly 400,000 adults over 20 years found that daily multivitamin users had a 4% higher mortality risk compared to non-users. The research showed no mortality benefit whatsoever—contradicting the belief that multivitamins serve as health "insurance". Interestingly, multivitamin users typically had healthier lifestyles overall, yet still showed increased risk.
For healthy adults without diagnosed deficiencies, the healthiest nutrients come from food sources, not processed pills. Some specific concerns include potential buildup of excess iron or niacin from daily use. This reinforces that supplementation should be targeted and evidence-based, not indiscriminate.
Not OP obv, but based on the sample size and NIH reference I found the paper and the following down in the results section:

Thanks for finding the study.
I can't be bothered reading and understanding the whole paper, (and it's probably out of reach for me anyway), but it's notable that this quote is not from the abstract but from the results analysis.
The Abstract says:
The abstract doesn't say that MV use increases mortality.
That being the case the title to this post seems sensationalised at best.
Yup exactly I was quoting that part to point out that it was only found in the results of the meta analysis of all the studies in follow up period 1 but I wasnt very specific about that, i.e. I was not intending to validate the title's claim.
