Best multivitamin of 2025, tested and reviewed by a registered dietitian

Fitting all your nutrient needs into three meals a day? Easier said than done. Even with the best intentions, life happens, so a multivitamin can be a convenient way to fill nutritional gaps. "I like to look at a multivitamin as a safety net — it ensures you are getting all of the nutrients you need, even if you are eating a balanced diet," says Bridget Isaacs, registered dietitian of Nutrition by Bridget, who also points out that its possible to eat a balanced diet but to still come up short on some nutrients.

That said, choosing the right multivitamin is no small task. A trip to the pharmacy or supplement aisle reveals hundreds of brands and options, each with different formulations, quality and price points. There are multivitamins tailored to every lifestyle, dietary preference, health concern and age or gender-specific need. The choices can feel overwhelming.

To help you make an informed decision, we consulted three registered dietitians to break down what to look for in a multivitamin and the key differences between various types. Using their feedback and my own decade of experience as a registered dietitian, we researched products from over 15 brands and put 16 different multivitamins to the test to find the best multivitamins for 2025.

Types of multivitamins

Choosing the right multivitamin isn't as simple as grabbing the first bottle you see on the shelf. Multivitamins come in various formulations tailored to specific life stages, health needs and preferences. Here's a breakdown of the most common types:

• Men's: Formulated to meet men's unique nutrient needs, these are typically iron-free and higher in zinc, B vitamins and vitamins A, C and K. Some may also include extras like CoQ10 to support prostate health, fertility or sports performance.

• Women's: Designed for women's specific health concerns, these are higher in iron and folic acid to support menstruation and fertility. Many also include herbs or nutrients to address bone health, hot flashes or hormone balance.

• Prenatal: Created for pregnancy and breastfeeding, these contain higher amounts of key nutrients to meet the increased demands of this life stage. Some also include ginger to help combat morning sickness.

• 50+: Tailored for adults over 50, these typically provide more vitamin D and B12 while reducing iron content to match changing nutrient needs and deficiency risks. These products often contain antioxidants and other nutrients to support healthy aging, including eye, heart and brain health.

• Children's: Between periods of immense growth, brain development, physical activity and bouts of picky eating, kids' nutrient needs are constantly evolving. Children's vitamins are formulated for specific ages and often contain sweeteners or flavors to make them more palatable. Kids metabolize nutrients differently than adults, making them more prone to nutrient toxicities. For this reason, choosing a kid's vitamin that's specifically formulated for their age is essential.

• Gummy: Gummy vitamins are popular for their ease of use and sweet taste. However, because they're typically made with added sugars and gelatin, they aren't always suitable for people trying to manage their blood sugar levels or those following a vegan diet. If you have kids in your house, keep gummy vitamins tightly sealed and out of reach.

• Liquid: Liquid vitamins are a good option for people who dislike swallowing pills. Plus, the nutrients in liquid multivitamins are typically more readily absorbed than those in pill or capsule form. The downside? There aren't as many options, and they don't always taste great.

• Capsules/tablets: The vast majority of adult multivitamins are capsules or tablets. Soft gel capsules are more expensive than tablets but are easier to swallow, digest and absorb.

• Athletic performance: Some multivitamins include nutrients, like CoQ10, to support athletic performance and recovery. Highly active individuals often have greater nutrient demands, so many sports multivitamins contain elevated levels of specific vitamins and minerals.

• Organic and whole-food-based: These multivitamins derive nutrients from real foods rather than synthetic nutrients made in a lab. While synthetic nutrients benefit some, whole-food-based nutrients may be higher quality and easier to absorb. If eating organic is a priority, look for USDA-certified options.

• High-potency: These contain higher doses of vitamins and minerals and are designed for those with significant nutrient deficiencies. However, consult a healthcare professional before use.

• Vegan: Made without animal-derived ingredients, these are perfect for those following plant-based diets. If animal welfare matters to you, look for cruelty-free or certified vegan products.

Factors to consider when purchasing multivitamins

Finding the right multivitamin doesn’t have to be complicated, but it does require a little strategy. Are you aiming to target specific health goals, or do you just need something to fill small nutritional gaps? No matter your needs, here are some considerations when looking for the best multivitamin:

• Nutrient content and dosages: Choose a multivitamin with a formulation that aligns with your nutritional needs and lifestyle. Gender- and age-specific options can help address unique requirements, like higher iron for women or increased vitamin D for older adults.

• Form: The best multivitamin is the one you'll actually take. Softgels are generally easier to swallow than tablets, but gummies or liquid options can be great alternatives if you can't swallow pills.

• Artificial additives: Aim for products with minimal artificial additives for a cleaner supplement. Avoid unnecessary colors, flavors, sweeteners, fillers or preservatives whenever possible.

• Third-party testing: Opt for a multivitamin that's undergone third-party testing by trusted organizations such as NSF or USP to guarantee the label accurately reflects the contents within.

• Dietary restrictions: If you follow a specific diet or have allergies, look for products that align with your needs, such as vegan, gluten-free or dairy-free options. If you have severe allergies, consider supplements made in allergen-free facilities to minimize the risk of cross-contamination.

• Specific health goals: Select a multivitamin with scientifically backed ingredients for targeted support. Whether you need support for heart health, bone strength or prostate health, a tailored formula can make a difference.

• Value: You don't have to break the bank to find a quality multivitamin. Compare serving sizes and ingredient quality to find an option that fits your budget while still delivering the necessary nutrients.

How we chose multivitamins

Selecting the best multivitamin was no easy task. As a registered dietitian with nearly a decade of experience in dietary supplements, I've dedicated myself to staying current with the latest products and research to provide informed recommendations. To complement my expertise, I consulted with three fellow registered dietitians to gather additional insights on multivitamins and key considerations, including the ongoing debate between synthetic and whole food-based formulations.

After an in-depth review of more than 30 products from more than 15 brands, our team — assisted by family and friends — rigorously tested 16 multivitamins. Each product was evaluated for at least two weeks for factors such as ease of use, taste, cost and overall user experience.

FAQs

How often should I take a multivitamin?

Taking a multivitamin consistently is key to reaping its full benefits. "Always follow directions on the label, but best practice is taking a multivitamin daily," says Isaacs. Regular daily use helps fill nutritional gaps and ensures your body receives a steady supply of essential vitamins and minerals. Remember, the exact dosage and timing may vary by product, so always check the label for specific instructions tailored to your chosen supplement.

Are multivitamins necessary if I eat a balanced diet?

If your diet is well-rounded and nutrient-rich, multivitamins might not be necessary. However, certain gaps can still occur, making supplementation helpful.

Registered dietitian Emily Hulse of Emily Grace Nutrition, explains, "Certain conditions or dysfunctions in our bodies may reduce how much we can digest and absorb nutrients from even the most balanced diet." Factors like age, medical conditions and lifestyle can influence nutrient absorption and create deficiencies. To determine if a multivitamin is right for you, consult a healthcare professional or registered dietitian who can assess your needs.

What is the difference between synthetic and whole-food multivitamins?

Synthetic multivitamins are made using nutrients created in the lab, whereas whole-food multivitamins derive most of their nutrients from food sources. The debate over which is better remains ongoing, but some studies suggest that whole-food-based nutrients may be easier for the body to absorb.

Ultimately, the choice between synthetic and whole-food multivitamins depends on your preferences, health needs and budget. Both types can provide essential nutrients to support your overall wellness.

Can multivitamins cause side effects?

Multivitamins can sometimes lead to gastrointestinal side effects, such as nausea, especially if taken on an empty stomach. Additionally, certain nutrients can become toxic when consumed in excessive amounts. For this reason, it's important to follow dosing directions and avoid doubling up on multivitamins or other supplements, says Jessica M. Kelly, registered dietitian of Nutrition That Heals, LLC.

How do I choose the right multivitamin for my age and gender?

The best way to determine the right multivitamin for your needs is to work with a registered dietitian. They'll consider factors like your diet, health history, wellness goals, physical activity level, age and gender. It's also crucial to look for a product made by a reputable brand that has been tested for purity and potency, ideally by a third-party lab.

Other products we tested

Not every multivitamin made the cut for our top rankings, but several products still stood out for specific needs or preferences. Here's a closer look at those that didn't quite make the top tier but are worth considering for the right person:

• EllaOlla Toddler's Unflavored Multivitamin: We appreciated the concept of EllaOlla's powder multivitamin for toddlers, which also comes in a version for older kids. The formula is comprehensive and free of added sugars, making it a thoughtful choice for parents. However, it is on the pricier side, and its effectiveness can be tricky to gauge if your toddler doesn't entirely consume the food or drink it's mixed into.

• MegaFood Women's Once Daily: This whole food women's multi is a good option if you prefer to take your multivitamin on an empty stomach. But, its rougher texture and larger size make the capsule harder to swallow than other women's multivitamins we tried.

• MegaFood Men's Advanced 55+: As with all MegaFood supplements, we'd love to see third-party testing done to confirm its potency and purity. Still, thanks to its high dose of vitamins D and B12, MegaFood Men's Advanced 55+ is one of our top picks for men over 50. We also like that it includes selenium and choline, two nutrients essential for brain health as we age.

• Mary Ruth's Liquid Morning Multivitamins: For those who dislike swallowing pills, Mary Ruth's line of liquid morning multivitamins is worth considering. The products are third-party tested and available in sweetened and unsweetened varieties. While our testers liked the flavors, they weren't a fan of the vitamin's thick consistency.

• Optimum Nutrition Opti-Women: This multivitamin is a solid choice for active women who may struggle to meet their iron needs through diet alone. Although the product lacks third-party certification, we appreciate that all Optimum Nutrition products are manufactured in Informed Sport-certified facilities, ensuring quality production standards. The formula's high nutrient doses and inclusion of herbs are noteworthy, though they may warrant consideration depending on individual needs — not all herbs are appropriate for all individuals.

• Thorne Men's Multi 50+: If you can overlook the requirement of taking six capsules daily, this multivitamin for men over 50 is an outstanding option. Backed by Thorne's trusted reputation for high-quality supplements, it's designed for optimal absorption and includes key nutrients like vitamin B12 and selenium, essential for promoting healthy aging.
