Daily Multivitamins and Longevity: What Recent Studies Reveal

In a recent study published in JAMA Network Open by the National Institutes of Health (NIH), it has been found that daily multivitamins may not help you live longer, contrary to popular belief. Researchers analyzed data over a span of 20 years from nearly 400,000 healthy adults and discovered that taking a daily multivitamin did not lower the risk of death from conditions like heart disease or cancer. In fact, healthy individuals who took multivitamins were slightly more likely to die during the study period than those who did not. Experts, like registered dietitian nutritionist Melissa Prest, emphasize that a balanced diet and healthy lifestyle are far more crucial for longevity. For many, discussing supplementation needs with a healthcare provider or dietitian can provide personalized guidance on whether multivitamins are necessary or beneficial. Have you ever wondered if those daily multivitamins you take are making a difference in your lifespan? While the convenience of getting all your essential nutrients in one pill might be appealing, new research questions whether these supplements actually contribute to a longer life.

Daily Multivitamins May Not Help You Live Longer, Study Finds

Daily Multivitamins: An Overview

Multivitamins are dietary supplements that contain a combination of vitamins, and sometimes minerals, in one convenient pill or tablet. These supplements are designed to fill nutritional gaps in your diet and to help ensure you get the necessary nutrients your body needs to function properly. However, recent studies are casting doubt on whether these multivitamins can actually extend your lifespan.

What Are Multivitamins?

Multivitamins are essentially a mixture of different vitamins and minerals found in various foods. They can include vitamins such as A, C, D, E, and K, as well as B-complex vitamins like B12 and folate. Minerals such as calcium, magnesium, and zinc are also commonly included.

These supplements come in various forms including tablets, capsules, chewable gummies, and even liquids. Many people take them as an easy way to boost their nutritional intake.

The Study: An Eye-Opening Revelation

A recent study published in JAMA Network Open analyzed data collected over a span of 20 years from nearly 400,000 adults. Participants had a median age of 61.5 and were generally healthy.

Key Findings

Researchers found no significant evidence that daily multivitamin consumption reduced the risk of death from heart disease, cancer, or other common illnesses. In fact, there was a slight increase (4%) in the risk of death among those who took multivitamins compared to those who did not.

Factor Observation
Duration 20 years
Number of Participants Approximately 400,000
Health Status Generally healthy, median age of 61.5
Total Deaths Reported Nearly 165,000
Impact on Longevity No significant reduction in death risk; slight increase in risk (4%) for takers

The study did not include individuals with pre-existing vitamin deficiencies, which means the data might not extend to populations that may actually need supplements for medical reasons.

 

Why Take Multivitamins?

Many people include multivitamins in their routine for various reasons such as boosting energy, dealing with stress, or simply aiming to live a longer life. But if they don’t necessarily prolong life, what’s their purpose?

Nutritional Gap Fillers

According to Melissa Prest, D.C.N., R.D.N., multivitamins serve to supplement the nutrients you might miss in your diet. They are particularly useful for people with poor dietary habits or conditions that hinder nutrient absorption.

Expert Opinions

Stephen Vogel, M.D., points out that the majority of longevity studies emphasize diet and lifestyle over supplements. He states that for generally healthy individuals with no known deficiencies, there’s insufficient evidence to support that multivitamins improve lifespan.

Should You Stop Taking Multivitamins?

Given the findings, the question remains: should you continue your daily multivitamin?

Tailor to Individual Needs

Ultimately, taking a multivitamin should be tailored to your specific needs. Some people might still benefit from them, especially those with poor diets, certain health conditions, or for whom nutrient absorption is an issue.

Consult Healthcare Providers

Dr. Vogel suggests discussing your multivitamin use with a healthcare provider who can assess your dietary habits and health history to guide you better. You could also consult a registered dietitian nutritionist.

Multivitamins and Specific Deficiencies

Who Might Benefit

Certain populations could still gain from multivitamins:

  • Those with alcohol addiction
  • People with low fruit and vegetable intake
  • Vegans
  • Individuals who have undergone bariatric surgery

These groups are at higher risk of nutrient deficiencies and might require supplements to compensate for those gaps.

Potential Downsides

For everyone else, especially those with a balanced diet, the study suggests that the cost and effort of taking daily multivitamins may outweigh the benefits. Unregulated compounds in some supplements can also be a concern.

Conclusion: A Balanced Approach

Focus on Diet and Lifestyle

Experts like Melissa Prest advise that food and lifestyle should be your primary focus. Aim to get enough sleep, eat a variety of fruits and vegetables, and incorporate regular physical activity into your routine for overall health and longevity.

Reading Labels

Not all multivitamins are created equal. They have different compositions and varying amounts of each nutrient. Therefore, it’s essential to read supplement labels carefully to ensure you’re not overdoing any particular vitamin or mineral.

The Bottom Line

While the study casts doubt on the efficacy of multivitamins for extending life, it doesn’t entirely dismiss their utility. They can be beneficial for those with specific deficiencies or dietary issues. Always consult healthcare providers for personalized advice.


Remember, multivitamins are supplements, not substitutes for a healthy diet. They are not medicine and should not be used as a cure for diseases. Be cautious, especially if you’re pregnant, nursing, or considering giving them to your children. Making an informed decision about multivitamins can help you maintain better health and wellness.


Could your one-a-day vitamin supplement be doing more harm than good? The truth is, while multivitamins might not necessarily make you live longer, they can still play a role in filling nutritional gaps for those who need it. Always consult with professionals to tailor these supplements to your own needs. And don’t forget—the foundation of good health lies in a balanced diet and a healthy lifestyle.
