Best Vitamin Brand for Essential Micronutrients: Transparent Labs Multivitamin

White pill bottle with blue writing that says "MULTIVITAMIN" against a red background

Key features

  • Essential minerals and select vitamins for wellness
  • Third-party testing certificates available for all products
  • Targeted to people living active lifestyles and athletes

Transparent Labs cites transparency as its top priority for its products. The brand says that this isn't just about being truthful about what's in the product; it also refers to an ingredient's health claims that are backed and reviewed by its advisory board.

The Transparent Labs multivitamin includes several nutrients in bioavailable forms to help with absorption. Bioavailability means the body can absorb, use and store the vitamins and minerals in the supplement. The multivitamins also include a few extra nutrients you don't usually see in a multivitamin, like ashwagandha, an adaptogen known for its stress-relieving properties, and N-acetylcysteine (NAC), a potent antioxidant.

Pros:

  • Bioavailable forms of many vitamins and minerals
  • Added botanicals and nutrients for whole-body health
  • No artificial colorings and no filler ingredients

Cons:

  • Doesn’t contain certain B vitamins and minerals that other complete multivitamins on the market provide
  • Some nutrients are significantly higher than RDA increasing the risk of going above the upper limit of a vitamin or mineral

Cymbtiotika is our pick for the best brand for stress and sleep support because of the wide range of supplements it offers. From sleep-supporting magnesium supplements to mood-boosting Lion’s Mane supplements, you’re sure to find a product to ease your stress and improve your rest.

Brown pill bottle with a beige and blue label that says "gut+" next to two capsules

Key features:

  • Single product brand
  • Supplement includes probiotics, prebiotics and digestive enzymes
  • Shelf-stable (no refrigeration needed)

When it comes to gut health, probiotics are one of the most effective ways to alleviate constipation, improve digestion and ease bloating and other symptoms related to IBS. Probiotics also benefit women specifically as they may improve vaginal health.

While many supplement brands offer multiple products, YourBiology only focuses on one: gut+. Each dose of gut+ contains 20 billion CFUs from 10 probiotic strains, which is why it’s our pick for the best vitamin brand for gut health. In addition to probiotics, gut+ also contains prebiotics and digestive enzymes. Prebiotics provide digestive health benefits, such as helping regulate bowel movements. We like that this supplement also includes vitamin D, which may improve our immune system.

Best Vitamin Brand for Healthy Joints: Utzy Naturals

Three blue pill bottles against a red background

Key features

  • Multiple supplements to support healthy joints
  • No artificial sweeteners or coloring
  • All products are third-party tested

Joint discomfort can be caused by inflammatory substances in your cells, wearing down your cartilage and causing the connective tissue that lines the inside of your joint capsules to swell, according to the National Institute of Health (NIH). Utzy Naturals offers three supplements that contain ingredients to help reduce inflammation, which in turn can help support healthy joints.

Here is a quick overview of each product from the brand’s Joint Health Bundle:

  • Coll-U-Gen: This flavorless collagen powder drink mix uses UC-II, an undenatured (meaning not processed by high heat) type II collagen from chicken cartilage. Type II collagens can help teach your immune system to stop attacking your joints, preventing damage and reducing inflammation, according to research published in Nutrients. Additionally, Coll-U-Gen has Fortigel, a type III bovine collagen, which may be particularly beneficial for athletes. A small study published in Current Medical Research and Opinion found that athletes who supplement with bovine collagen experience less joint pain.
  • Inflavinol: This capsule supplement is a blend of herbal extracts that Utzy says support a healthy inflammatory response. One ingredient is boswellia phytosome extract (as Casperome). Boswellic acids can help stop the production of certain chemicals and lipids that are involved in the body’s inflammatory response, according to a review published in Current Medical Research and Opinion. In the same review, researchers noted that boswellic acids have also been shown to protect tissues from damage.
  • Agilen: Agilen is a calculated combo of glucosamine and chondroitin sulfates, and both help to support cartilage formation, Utzy says—a claim backed by a 2011 study in the International Journal of Rheumatology. Ingredients also include hyaluronic acid, a buzzy ingredient for anti-aging skin serums that studies show also helps to alleviate osteoarthritic pain.

For additional bone health, you could also add Utzy’s Vitamin K2 & D3 supplement to your stack. Vitamin D deficiency can result in joint pain, according to a study published in the Annals of the Rheumatic Diseases; another study found that vitamin D mitigates inflammation.

Pros:

  • Committed to testing and transparency
  • Multiple joint health supplement options are offered
  • Subscription option offers savings and free shipping
  • Lots of robust praise and high marks from non-incentivized customers

Cons:

  • Ingredients differ in joint supplements so you may need to purchase the whole bundle to cover bases

The Best Vitamin Brands

We asked Aaron Gravely, MD, to weigh in on how to identify the best vitamin brands on the market in 2024:

Vitamin supplements can provide significant benefits to your physical and mental health. But the lack of strict FDA regulation within the dietary supplement industry leads to a ton of variability in product quality from brand to brand. If you’re not vigilant, you can end up with a product that has contaminants, one that has ingredients that don’t match what’s on the label or one that’s simply a waste of your money.

Furthermore, vitamins and minerals are subject to complex biochemical processes once they enter the body, and this means that the chemical form of the vitamin (e.g. vitamin C as ascorbic acid versus vitamin C as sodium ascorbate) and its accompanying cofactors (or lack thereof) can have a huge influence on its effectiveness. But without at least some basic knowledge of biochemistry, it can be difficult to decipher which vitamin forms are better than others and which ones are best for you, specifically.

What this all boils down to is that finding the best vitamin companies and products is more complicated than most people realize. There are a lot of moving parts to consider and honestly, it would take an entire book to cover everything. But in the next section, I’ll lay out some key considerations that go into my vitamin selection process and which products I like best and why. Hopefully you’ll walk away better equipped to navigate the vitamin industry and ultimately be able to find the products that are best for your body and your wellness goals.

Third party testing

The very first thing I look for in any supplement product is a seal that indicates it has been third-party tested. Since the FDA doesn’t strictly regulate dietary supplements, third-party testing is the only way to know you’re getting a safe, quality product. The industry’s most reputable third-party testers include NSF, USP, ConsumerLab and UL Solutions.

To fully appreciate the importance of third-party testing, consider the findings of a study conducted on herbal supplements in 2013. It found that 59 percent of the products it looked at contained ingredients that weren’t listed on the label and one-third of the products contained contaminants and/or fillers not listed on the label. Additionally, 83 percent of the supplement companies had actually substituted the active ingredient for something else. Another study on vitamin D3 supplements found that the concentrations of individual pills varied wildly, from nine percent to 146 percent of the listed dose.

Consequently, there are a limited number of vitamin brands you can trust to provide high quality supplement products. Ritual is a top rated brand in this regard because it’s not only one of 10 vitamin brands with USP Verification, but it also provides full transparency on the sources and suppliers of its ingredients.

Ingredients

When it comes to a product’s ingredients, there are two major things to consider: First, the vitamin’s form and second, the presence or absence of cofactors and enzymes that help the vitamin to be absorbed and used by the body.

Vitamin form

When you look at a product’s label, the active ingredient is typically followed by another name in parenthesis. For example, you may see: Vitamin B12 (methylcobalamin). The name in parenthesis is the chemical form of the ingredient and most vitamins have several forms. To understand why this matters, let’s look at the example of magnesium.

Magnesium is a trace mineral that has become a popular supplement for sleep. It comes in multiple forms and the ones you’ll see most commonly in dietary supplements are magnesium glycinate, magnesium citrate, magnesium malate, magnesium threonate and magnesium oxide. So how do you choose?

I typically avoid magnesium oxide because it’s a cheaper, less bioavailable form of magnesium. Still, the remaining forms each have their own pros and cons depending on your needs. For example, if you struggle with constipation then you might consider magnesium citrate because it has a laxative effect. But magnesium aside, the main takeaway here is that this type of specificity can be applied to virtually every type of vitamin and mineral supplement on the market. As a result, finding the best vitamin brand and product depends heavily on your personal needs. Doing your due diligence can pay off in a big way.

Cofactors and coenzymes

Despite the fact that vitamins from supplements and vitamins from food sources can be chemically identical, you’ll often hear health professionals claim that it’s always better to get your vitamins from your diet. The rationale behind this sentiment is that vitamins from food sources tend to come in synergistic combos with other helper molecules that are essential to the vitamin’s absorption and utilization by the body. On the other hand, dietary supplements tend to provide the vitamin as an isolated part.

Nonetheless, there are certain vitamin brands that take this into account. AG1 is one of my favorite products because its formula includes support complexes. These complexes consist of cofactors and coenzymes that protect and stabilize the key nutrients and help release energy from them. This means you’re able to get the full nutritional benefits of the active ingredients in a way that is biologically efficient.

Beyond support complexes, I also tend to look for products that include liposomes or liposomal formulations. In essence, this makes the active ingredient more fat soluble and protects it from being broken down in the stomach and small intestine before it can do its job.

Wellness goals

As I mentioned, specificity is key to understanding a product’s potential impact on your body. For example, if you’re someone who has had liver issues in the past and you want to supplement with vitamin B12, you might consider a product that uses methylcobalamin over cyanocobalamin. As a synthetic form of B12, cyanocobalamin involves more liver processing when used by the body.

Or, let’s say you’re someone looking to improve your gut health, so you seek out a probiotic supplement. Most probiotic supplements prominently feature the number of cultures (or CFUs) on the front of the package and it can be tempting to go with whichever product has the highest number. But my advice is that you look at the back of the label to see how many different strains of bacteria the product has. Diversity in your microbiome is a key factor for gut health, and a probiotic product with a more diverse strain offering can often (but not always) provide greater health benefits.

Additionally, I prefer probiotic supplements that also contain prebiotic ingredients because they’re important to fuel the growth of the probiotics you consume. That’s why I prefer Ritual Gut Health as a probiotic supplement. It contains prebiotics as well as postbiotics to provide a comprehensive wellness blend for your gut that many other products lack.

Benefits of Vitamins

It’s true that vitamin supplements can’t compensate for poor nutrition over a long term and a well-balanced diet will always reign supreme. Nonetheless, many people can derive tremendous benefit from supplements in a way that can be more cost effective than trying to obtain the same nutrients from food. Moreover, vitamin supplements can act as an insurance policy against any deficiencies that might exist within your diet.

Furthermore, if you are someone who always eats a perfectly balanced diet, realize that vitamins and nutritional supplements can help you better absorb and utilize the nutrients you’re getting from your food. This is especially true if you suffer from digestive issues, as some synthetic vitamin formulations are more absorbable than their natural counterparts.

How do I know if my body is lacking vitamins?

In some instances, a vitamin panel blood test can help reveal vitamin and nutritional deficiencies. But these tests aren’t always reliable, and they’re not particularly useful for detecting deficiencies in minerals that are very tightly controlled by the body’s biochemistry. An example of such a mineral is magnesium. Many adults are deficient in magnesium. However, a non-severe deficiency in magnesium isn't likely to show up on a blood test because the body tends to pull magnesium from bones and other tissues rather than from the blood serum.

For this reason, it’s important to be able to read your body for signs of possible vitamin deficiency. These signs include:

  • Fatigue
  • Dizziness
  • Unexplained weight loss
  • Loss of appetite
  • Numbness or tingling in the hands and feet
  • Muscle weakness
  • Sudden hair loss
  • Brittle or discolored nails
  • Pale or yellowish skin
  • Irregular heartbeats
  • Shortness of breath
  • Frequent mood changes
  • Unsteady movements
  • Forgetfulness or loss of focus

If you experience any of these symptoms, consult your doctor for additional guidance.

Who Are Vitamins Best For?

Think of vitamin supplements as a backup plan. Ideally, the vitamins and minerals you need come from your food first, and vitamin supplements fill in the gaps. A diverse and balanced diet should be your foundation, but supplements can help optimize health.

Some people have health conditions or are in life stages requiring extra nutrients—like pregnant people, people with chronic illness or even competitive athletes. Sometimes digestion or absorption can be impaired due to a health condition, or people may even have genetic predispositions that make it harder for them to absorb or utilize certain nutrients. In these cases, vitamins and minerals in supplement form can be helpful. It's always best to check with a healthcare professional if you aren't sure whether or not you need to supplement your diet.

Who Might Not Benefit From Vitamin Supplements?

Not everyone needs a supplement. Children, for example, usually get all the nutrients they need from a healthy diet. And for healthy adults eating a varied diet in reasonably good health, vitamins may not be necessary, but they still could be beneficial.

How To Choose the Best Vitamin Brand for Your Needs

Identify your needs

When choosing a vitamin brand, it helps to start by examining why you are taking the supplement in the first place. Is it to improve your overall health, or are you trying to address a specific health concern?

What's important to you can dictate the type, and even the brand, of vitamin supplement you choose.

Read the ingredient label

The ingredient label on your supplements gives you important information to help you decide. Like a food label, you can check for unwanted ingredients like fillers (added to supplement products to bulk them up), artificial sweeteners, colors or preservatives. Many options don't have any of these, so there's no need to settle for something that does.

If you have food sensitivities or allergies, reading a label is also important to avoid accidentally taking in an ingredient that could trigger a reaction. Never assume something is free from your allergen if it doesn't explicitly say so on the bottle.

Consider the cost

You don't need to spend a fortune on your supplements, but the reality is that not all supplements are created equal. Just because you find a jumbo-sized container of fish oil at an affordable price doesn't mean it's a good deal. In fact, it could be lower quality and less effective than a smaller bottle of a more expensive brand.

Some companies will spend more money on third-party testing or sourcing high-quality ingredients, which translates to a higher-priced product.

Look for third-party testing and certifications

Third-party testing or certification means the product has been sent to an outside organization for verification. It won't tell you whether the product is effective, but it will confirm that it is safe and contains the ingredients listed on the label. This differs from the company making its own claim that a product is "safe and effective."

Some third-party testing companies have better reputations than others. The big names to look for are NSF International and U.S. Pharmacopeia (USP). It can be cost-prohibitive for small or new vitamin brands to pay for these, and it's absolutely possible to find good products without them. But if you're looking for an extra level of safety and quality assurance, these logos should be on the bottle.

Keep dosage in mind

You want your product dosage to match the effectiveness seen in research. Otherwise, you may not get the results you're looking for, or worse, you could take too much and experience side effects.

The tolerable upper limit is the maximum amount of a nutrient you can take in a day without experiencing adverse effects. Taking too much of specific vitamins and minerals can lead to issues like gastrointestinal distress, liver damage and birth defects.

Some supplements are toxic in higher doses and can be harmful. Taking multiple supplements with overlapping ingredients can put you at risk of taking too much of one nutrient. It's essential to be aware of the ingredients in your supplements and pay attention to your overall intake from each one.

Find the best form

Vitamins come in many different forms. Pills or gel capsules are what we see most often, but gummy supplements are increasingly popular. If you have trouble swallowing pills, chewable vitamins are a great option. Another choice is liquid or even soluble vitamins, like AG1, which make getting your vitamins on the go easy. It’s important to consider your lifestyle and preferences when looking for a daily vitamin.

Consider interactions

Before taking any new vitamin, it’s important to consult with your doctor. This is because some vitamins can interact negatively with medications you may be taking, with dangerous or even life threatening consequences. According to the US Food & Drug Administration, some vitamins can even make your medications less effective or lead to internal bleeding or stroke.

Vitamin Brand FAQs

What should I avoid when buying supplements?

Generally, any supplement that makes grandiose claims, uses shady marketing tactics or doesn't have a clear and accessible ingredient list is a big red flag. Instead, look for clear, transparent language with third-party testing to back up any claims.

How do you know if you can’t trust a vitamin brand?

First, beware of any supplement that makes outrageous claims. If it sounds too good to be true, it probably is. Second, be cautious of any brand that's unclear about its ingredients or manufacturing process. And finally, don't trust a brand unwilling to back up its claims with evidence from research.

Are more expensive vitamins better quality?

Not necessarily. Many factors go into the cost of supplements, and the price tag isn't always an indication of quality. But in general, you get what you pay for. So if a company is selling a product way below the competition, it's likely because they've cut corners somewhere—whether in the quality of ingredients, the manufacturing process or third-party testing.

Can you overdose on vitamins?

Yes, vitamin overdose can occur accidentally, or intentionally, if you take more than the recommended supplement amount. If you or someone you know may have overdosed call your local emergency services or the national Poison Help hotline (1-800-222-1222)

Does it matter if I take all my vitamins together?

According to the US Food & Drug Administration, mixing supplements with medication could have dangerous effects because of the potential for negative interactions. Furthermore, certain vitamins and mineral supplements can compete with each other when absorbed. Before taking any vitamins it’s best to talk with your healthcare provider.
