Multivitamin Supplements Don't Help You Live Longer, Major Study Shows (go.com) 129

A study from the National Institutes of Health (NIH) analyzed data from nearly 400,000 healthy adults over 20 years and determined that "multivitamin use to improve longevity is not supported." The findings were published in JAMA Network Open. ABC News reports: The study found no evidence that daily multivitamin consumption reduced the risk of death from conditions such as heart disease or cancer. Rather than living longer, otherwise healthy people who took daily multivitamins were slightly more likely (4%) than non-users to die in the study period, according to researchers. Researchers reported nearly 165,000 deaths occurring during the follow-up period of the study, out of the initial group of 390,000 participants. The study, however, did not analyze data from people with pre-existing vitamin deficiencies. "What this study shows is that, generally, multivitamins aren't going to help you live longer," Dr. Jade A Cobern, MD, MPH, board-certified physician in pediatrics and general preventive medicine, told ABC News. "Even though the cost of many multivitamins isn't high, this is still an expense that many people can be spared from."

    Some people have absorption problems and really need vitamin supplements to avoid problems like rickets, scurvy and night blindness to name a few. Some need it to recover quicker when they are sick. For most others it improves the quality of their pee.
    • The problem is they put a lot of crap in multivitamins, too. I'm willing to believe that -4% could be whittled down to 0% by omitting just a couple of the ingredients, or at least dramatically decreasing their quantities. It's possible there's a genetic factor too, where literal nutritional guidelines aren't actually a "one-size-fits-all" type thing.

        Among other things, it could also be that people who know they are sick are hoping the vitamins will help. In other words a selection bias in the vitamin takers.

        • by Malc ( 1751 )

          Or conversely, maybe some people taking multivitamins don't feel they have to eat so healthily, don't bother with fruit, etc?

          • And that is the big problem. My celiac disease afflicted wife finds that multi vitamins help her a lot - but only when taken with good, decent food. I have always assumed since she has a bit of a mal-absorbtion problem in her digestion that she merely needs more. And if you take it with food like high quality protein, veg, fruit, your body will ramp up to absorb them anyway.
            • this. not just celiac but Crohn's as well:

              "Some studies suggest that low vitamin D levels may lead to an increased risk of surgery and hospitalisations, particularly in people with Crohn's. Another study found that giving vitamin D supplements to people with Crohn's reduced the risk of having a flare-up. Some people with IBD may be calcium deficient."

              etc etc

        Actually, the problem goes deeper. For some vitamins, overdosing is actually bad for you. You should for instance not overdose Vitamin A, which can be actually lethal. Most supplements luckily don't contain Vitamin A, but beta-Carotine instead, which then gets metabolized in Vitamin A if needed, or stored in the skin if not, turning your face orange. Overdosed Vitamin C gets thrown out via the urine, but doing so affects your kidneys, and it might lead to kidney stone disease.
        • which is very true, of course. The big question is "What is optimum dose?" If we know less than 60mg of vitamin C leads to scurvy, that's very useful, but what is the correct amount for optimum health? Nobody really knows and my guess is that it varies based on individual constitutions.
          • by Sique ( 173459 )
            Thus you should adhere to the common wisdom: If it's not broken, don't fix it. If you don't suffer from health issue due to vitamin deficiency, don't supplement vitamins.

          • Studies show "eating....women" is not a significant source of dietary iron. Well, at least not while being legal in most places. /s

          • This is also something to be considered by men...if taking a multi-vitamin, most men should avoid the ones that contain iron...we generally get plenty of iron from eating....women, can use the extra due to loss of blood during menstruation.

            So, if you DO take a multi-vitamin, check the label if you are male.

            Many men have a genetic issue called hemochromatosis, which causes them to absorb iron really easily. It is very likely a genetic variation that is helpful for women for the reason you point out. Wasn't a super problem until things like Geritol came out.

      If those conditions are given, their physician will prescribe the right doses of the right vitamins. It will not be an off-the-shelf supplement. It will be only the missing vitamins in an individually determined dose.
      • by Sique ( 173459 )
        Or to be more specific: If the normal resorption via the intestines does not work for some vitamines, there is no point in overdosing the other vitamines while the missing ones are still not resorbed. Instead, people get vitamin shots directly circumventing the normal digesting process. This is typical for instance for Vitamin B12.

        Actually it may be so. For example the doctor might simply recommend taking a fish oil supplement.

          For people with a healthy cardiovascular profile, regular use of fish oil supplements, a choice of primary prevention, was associated with an increased risk of atrial fibrillation. For participants with a diagnosis of atrial fibrillation, however, regular use of fish oil supplements, as secondary prevention, had a protective effect or no effect on transitions from atrial fibrillation to major adverse cardiovascular events, atrial fibrillation to death, and major adverse cardiovascular events to death.

          TLDR: If you are healthy, don't use supplements, including fish oil supplements.

        The doctor will specify what to take - that's true. But you must buy it OTC in most cases. I've tried and pharmacies are confused and insurance won't pay - you just have to go get the Vitamin E or whatever OTC.

        I've changed from a multi to the specific things my doctor recommended after blood tests mostly to save money, but also to hit the right things.

      Thats a different thing. I take a multivitamin when I'm on a diet because I'm getting less than my bodies preferred amount of nutrients and shit, so I'll take a multivitamin to keep the liver happy.

      But for most people who have a healthy and sufficient diet, and don't have other conditions associated with vitamin deficits (eg mensturating women, or one of the conditions you mention etc) theres no scientific justification.

      The thing this study looked at was folks who dont *need* a multivitamin taking them for longetivity reasons, and it turns out that actually , your statistically shortening your lifespan (marginally) and are better off getting your vitamins from a better diet rich in vitamins and stuff.

      • It's hard to draw too much conclusion unless they study made sure that the people on the vitamin aren't letting it affect their behavior in other ways. I could easily see someone thinking that because they take a multivitamin that they can get by with a shittier diet or less exercise. It also says that they didn't consider data regarding pre-existing deficiencies.

      There is little harm in taking them (except perhaps to your wallet, although they are pretty cheap), and can help cover gaps in your diet. Arguably if your diet is not great then you have bigger problems than just making up for the missing vitamins, but modern life is what it is.

        Supplementing D vitamin in the winter if you live far enough north where the days are short is a pretty normal recommendation in official government recommendations. But it doesn't have to mean pills; vitamin D is added to milk for example, so if you drink 2-3 glasses of milk every day, you migth be getting all you need already.

        Old people often have some deficiencies due to worsening digestion over time, so they are in a completely different situation to younger healthy adults.

    From the study: "Not captured in mortality data, however, are potential benefits that do not affect longevity in cohorts of older adults."

    So, multivitamins still have a function, but as the title says, it isn't longevity. In particular, the following vitamins and minerals were listed as having health benefits - even when consumed via supplement:

    Beta carotene, vitamins C and E: slowing the progression of age-related macular degeneration
    Vitamins B12 and D: a convenient source of nutrients
    General multivitamin-mineral supplements: significantly more favorable change in episodic memory and global cognition (Effect of multivitamin-mineral supplementation... [sciencedirect.com])

It's easy enough to mix it up to avoid boredom, at least that's my experience.

        • by Mal-2 ( 675116 )

          It's not breaking the shell that's hard, it's keeping the "meat" intact in the process that is a problem. Brazil nuts tend to stick to the inside of their own shells, and cracking one often results in half the worthwhile material remaining stuck to shattered shell.

    • The so-called 'RDA' is survival levels of micronutrients, merely to prevent malnutrition-related problems, you need more than that.

Among daily MV users, 49.3% and 42.0% were female and college educated, compared with 39.3% and 37.9% among nonusers, respectively. In contrast, 11.0% of daily users, compared with 13.0% of nonusers, were current smokers. MV use was not associated with lower all-cause mortality risk in the first (multivariable-adjusted HR, 1.04; 95% CI, 1.02-1.07) or second (multivariable-adjusted HR, 1.04; 95% CI, 0.99-1.08) halves of follow-up. HRs were similar for major causes of death and time-varying analyses.

Participants were adults, without a history of cancer or other chronic diseases, who participated in National Institutes of Health-AARP Diet and Health Study (327732 participants); Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (42732 participants); or Agricultural Health Study (19660 participants).

    Just noticing that this is right next to the article on ultraprocessed food.

    Aren't vitamins also a severely processed food? Your body needs so many nutrients that a simple vitamin can't be the cure for a bad diet. If you lack a particular nutrient in your diet, such as iron or calcium, sure. Supplements can help that. But if all you're eating is these "ultraprocessed" snack foods no vitamin in the world would help enough. Eat a proper diet, enjoy a treat once in a while, and you'll have a longer and better life.

    • But if all you're eating is these "ultraprocessed" snack foods no vitamin in the world would help enough.

      Why not? If you can't answer that, there are scientists doing studies like this one, trying to answer the question.

      • Because the nutrients missing from ultraprocessed foods couldn't all be fit into one multivitamin, of course. You'd need something the size of a meal. At least a couple of protein shakes for starters. But then it's no longer "all you're eating is ultraprocessed foods" if you do that. And of course, nothing will remove the excess carbs except eating less of them.

      The only silver miming is that such researchers will eschew vitamins.

  • There are just so many possible interdependencies that I cannot imagine they can claim any sort of causality. Who take multivitamins, for example? it may well be that some of the people who do so are very healthy and live a long time - counterbalanced by the very sick and desperate, who die early. To actually determine something like this, you would have to control for many, many confounding factors to ensure that the groups are comparable.

My doctor openly states...they don't work, don't bother...same for my kid's doctor, etc.

    If taking a vitamin pill actually worked, there would be more effective and less effective formulations. Nearly anything that actually does something is poisonous if you get the dose wrong, so if Vitamins actually worked, there would be massive warnings all over the packaging about taking too many and news stories about weirdos who took too many pills 5 states away and died.

    I know diet is what many atheists use to fill the god-shaped-hole in their life, but nutrition is largely bullshit. I spent my entire childhood in near poverty and when I was a teenager everyone was saying you'll be fitter and healthier if you ate better....thinking that if I could afford an expensive healthy diet, somehow I'd feel better...it would cure my depression, make me less fat, make me stronger, and my mediocre food would stop poisoning me.

    So I graduated college, started earning good money, ate perfectly...and guess what...no noticeable difference. You can harm yourself by eating recklessly, obviously. Eat ice cream for dinner and your body won't thank you. However, eating 2000 calories of whole foods excellence or 2000 calories of poor person nutrition...all that matters is the number of calories and the macronutrient ratios (fat/protein/carbs).

    During the pandemic, I worked from home and started eating near perfectly (as well as exercising perfectly). I eat salads and fruits and protein and little else. I almost never eat bread or pasta and have largely cut out desserts and chips and most of the common abuses. When I eat carbs, it's whole grain rice or low carb tortillas. I balanced macros perfectly and have gone months eating perfectly....no change. I don't feel better. It doesn't hurt less to get out of a chair if I had a good workout that week. I take my multivitamin daily as well as a mineral supplement.

    Whether I ate 2 salads and protein shakes and no sweets that day...or the same number of calories of pizza and junk food....no difference. The only difference is that junk food is calorie-dense and often tastier, so it's much easier to overeat, but if you could control the calories, you won't see the difference (unless you really tried hard to wreck yourself, like lived off candy alone). I even bought into the glycemic index narrative...I can't tell the difference personally between whole wheat and white bread. I am not 100% sure that's bullshit, but I am skeptical and think the benefits of whole grains are exaggerated. I've stopped buying whole wheat hamburger buns for my kids (obesity runs in my family and my kids are a little overweight) and just buy them smaller white bread ones which have less calories and they like more anyway.

    Diet is just religion for city folks (and some major religions as well)...we're wired to need to do gestures to make our lives better and ignore that there's no evidence. Jews and Muslims think that a bacon cheeseburger will harm their relationship with god. My coworker thinks the same about gluten. He doesn't have celiac disease, he probably doesn't even have "gluten sensitivity." He just wants to believe that if he will achieve glory if he bakes with rice flour instead of wheat flour. It's something intangible for him to believe in. Vegans are the same way....oooh, you had butter?...well no dietary nirvana for you, sinner!!!!!!. I was the same with the gylcemic index and eating fresh fruits and vegetables. I still eat them because I think they're tasty, but whether or not I get beets from a can or from a farmer's market...there's NO difference. There's no difference between a 500 calorie salad vs a 500 calorie ham sandwich on white bre
  • I mean, I do want to stay young as long as possible, but I don't care if I live longer than the average human.
    What I DO want is to feel as good as possible as many days of my life as I can. For $2/day if a multivitamin improves your overall feeling of well-being it's not a waste of money.
