When you walk through the vitamin aisle or scroll online, the options can be overwhelming – multivitamins for women, multivitamins for men, gummies, capsules, energy boosters, immunity support. But do multivitamins work?
Let’s explore the facts behind multivitamins, their benefits and whether they’re right for you.
Do multivitamins work?
Depending on your needs, multivitamins can work.
Multivitamins are dietary supplements that typically contain a combination of essential vitamins and minerals like vitamin D, vitamin B12, iron, calcium, magnesium and more. If you don’t get all of your daily vitamins through your food, multivitamins may help fill those voids.
However, if you already eat a balanced diet rich in fruits, vegetables, whole grains and lean proteins, a multivitamin may not be necessary.
Still, certain populations, like older adults, people with food allergies, people who eat a plant-based diet or those with specific health conditions, may benefit from daily supplementation.
Are multivitamins good for you?
In most cases, yes, taking a multivitamin is good for you.
Taking a multivitamin as directed is generally safe. Taking a multivitamin can:
- Support your immune system
- Promote energy production
- Help with bone health
- Support your heart and brain function
Talk to your primary care provider before starting a new supplement. They can help you pick a brand and multivitamin that is best for your specific health. Don’t take more than the recommended dose. Too much of certain vitamins (like vitamin A or iron) can be harmful over time.
Need a primary care provider?
Is it good to take a multivitamin every day?
For most healthy adults, yes.
“A daily multivitamin can boost the essential vitamins your body gets. But it should never replace real food or a healthy lifestyle,” Anne Orzechowski, APRN, a primary care provider at OSF HealthCare, said.
If you’re unsure whether a daily multivitamin is right for you, it’s always a good idea to talk to your primary care provider.
What vitamins should I take daily?
That depends on your age, sex, health conditions, and lifestyle. In general, some of the best vitamins for energy and overall wellness include:
- Vitamin D for bone health and immune support
- B vitamins, especially B12 and B6, for energy and brain health
- Magnesium supports muscles and nerves
- Iron essential for oxygen transport in the blood
- Calcium for strong bones
If you’re feeling fatigued or stressed, your provider may also recommend supplements that can help ease anxiety symptoms and improve your energy levels and mood, like magnesium, B-complex or vitamin D.
Choosing the Right Multivitamin
Multivitamin for Women
Women often need more iron, calcium and folic acid, especially during childbearing years. A multivitamin for women or a daily vitamin specifically for women is designed to support hormonal balance, bone health and energy levels.
Multivitamin for Men
Men’s multivitamins typically focus on heart health, muscle function and prostate health, which provide nutrients like vitamin E, selenium and B vitamins.
If you’re unsure which to choose, talk to your provider about the best multivitamin for men or multivitamin for women based on your age and health.
The Benefits of Multivitamins
Taking a multivitamin approved by the United States Pharmacopeia (USP) can offer benefits like:
- Improved nutrition/vitamin absorption in the body
- Maintained energy levels
- Stronger immune system
- Reduced risk of nutrient deficiencies
- Mental health support (when combined with lifestyle changes)
“Multivitamins can be a helpful part of your health routine, but they aren’t magic pills,” Anne said.
If you’re thinking about taking a multivitamin, the best place to start is with your primary care provider or a registered dietitian. They can guide you on what your body truly needs based on your personal health history.
