How to find the best quality vitamins

Confused about vitamins? You’re not alone! The regulations on dietary supplements aren’t as strict as they are for medications, so it can be challenging to be sure you’re buying high-quality products that work. As a dietitian, I like to focus on food first.

With the right balance of nutrients on your plate, pills and powders are sometimes completely unnecessary! But other times, they really are needed if you have a nutritional deficiency.

When you chose a vitamin brand, you should keep in mind which product meets your nutritional needs, which ones meet quality testing, and which ones are the right price for you.

By the way, when you’re looking for high quality, reputable vitamin companies, one thing to focus on is that the dietary supplements are third-party verified. Verifiers include NSF International and USP.

Choosing supplement companies with third-party verification can help you be sure that you’re buying products that do what they say they will for health conditions and that herbal supplements and other products aren’t contaminated.

And while you can of course purchase trusted vitamins from stores like the Vitamin Shoppe, you can also check out such items from my Fullscript store.

This storefront is where I sell the best quality vitamin brands such as the above ones, as well as Klaire Labs, Biotics Research, Ortho Molecular, Standard Process, Nordic Naturals, Gaia Herbs, Garden of Life, and others.

You can find quality vitamins and minerals on this site that adhere to top manufacturing practices.

Now, read on for my supplements guide and to find out the best vitamin brands. I’ll go ahead and tell you that even if you’re eating a balanced diet, you may be missing out on some nutrients that can help optimize your health and even help your bone density.

The top supplements to try

Here are the picks for top vitamin brands and supplement companies you can trust from my registered dietitian colleagues!

What’s the best vitamin brand to buy? There are several that nutritionists recommend, according to quality standards and more.

Pure encapsulations multivitamin bottle

1. Multivitamin: Pure Encapsulations PureGenomics Multivitamin

“I love Pure Encapsulations supplements because they are independently tested for purity and potency and are free from wheat, gluten, egg, peanuts, artificial colors and flavors, and sweeteners,” says Lauren Harris-Pincus, MS, RDN, a dietitian in Green Brook, NJ and author of The Protein-Packed Breakfast Club.

“My favorite is the Puregenomics multivitamin, which has no extra fillers or binders and contains some activated B vitamins, particularly methylfolate, for better absorption.”

This is why many nutritionists rank Pure Encapsulations one of the top vitamin companies and one of the top quality supplement brands out there.

Ovega-3 bottle

2. Omega-3 supplement: Ovega-3 Vegetarian

This is the supplement I take on a daily basis because it supplies beneficial EPA and DHA omega-3s via algae, which is vegan. I consider Ovega-3 to be one of the best quality supplement brands for vegetarians.

You also are less likely to experience side effects with this product, as you might with some poorer-quality fish oil products. Want to know more about vegan and vegetarian omega-3 supplements?

Nature's Way women's probiotics

3. Digestive health supplement: Fortify Probiotics Daily Probiotic 50 Billion

Choosing the highest-rated probiotic supplements is no easy task, but you can consider Fortify Probiotics to be one of the top rated supplement brands!

This probiotic contains a high number of probiotic strains to support gut health and diversity, plus immune health. 

The capsule it comes in is also made to ensure the healthy bacteria can survive passing through the stomach.

bottle of vitamin D

4. Immune health supplement: Now Foods Vitamin D3

When it comes to immune health, it may surprise you to hear about vitamin D3. But this nutrient plays an important role in keeping your immunity up, and your body can suffer when you’re deficient.

It’s a good idea to get a baseline blood test of your vitamin D levels to see if you need a supplement. Vitamin D3 is much better absorbed by the body, versus vitamin D2.

5. Sleep supplement: Thorne Research Magnesium Bisglycinate

“Thorne brand is one of my favorites,” says Kelly Jones, MS, RD, CSSD, a sports dietitian in Philadelphia. “It not only has the NSF Certified for Sport verification but its quality is so high that it’s the official supplement line of a variety of U.S. national teams.”

So yup, it’s one of the best vitamin brands out there.

“The magnesium bisglycinate powder is great for anyone who needs a little help relaxing to fall asleep or who has very tight muscles,” says Jones. “I recommend it for both athletes with busy schedules as well as individuals with anxiety.”

bottle of Life Extension B vitamins

6. Energy supplement: Life Extension Complete B-Complex

This supplement contains a mix of B vitamins, including vitamin B12 and vitamin B6, to help keep your energy levels up.

The most important thing about the product is that the vitamins it contains are methylated. Your body more easily makes use of these types of vitamins!

Rainbow Light prenatal vitamins

7. Prenatal health supplement: Rainbow Light Prenatal Multivitamin

I like to recommend this prenatal multi to pregnant women, as it offers many highlights and is made by of the top vitamin brands.

For one, it contains a type of iron that is non-constipating. It also contains probiotics to aid digestion, as well as choline, a nutrient that we know is important for the health of a developing baby.

It does not contain DHA and EPA omega-3s, so you will have to take a separate supplement for this.

Rainbow Light postnatal multivitamins

8. Postnatal health supplement: Rainbow Light Postnatal Multivitamin

Many dietitians consider this pick one of the best-quality vitamin brands. “I’m a huge fan of Rainbow Light,” says Whitney English, MS, RDN, CPT, a dietitian in Los Angeles.

“The brand’s supplements are made at certified organic facilities and tested for purity by third-party labs. And they contribute $4 million of prenatal vitamins annually to women in need worldwide.”

“I really like their new line of vitamins, For the First Thousand Days, for moms and moms to be,” she says.

“I’m currently taking their postnatal vitamin, which is awesome because it includes an herbal blend (including folic acid) to support lactation for nursing mommies.”

Bottle of NOW turmeric and bromelain

9. Joint health supplement: NOW Turmeric & Bromelain Veg Capsules

Per two capsules of this supplement, you get 600 milligrams turmeric root extract and 300 milligrams bromelain, a combination that is incredible helpful for supporting healthy joint tissues.

Bromelain is an enzyme derived from pineapple that may reinforce normal immune system response––so the combination of both turmeric and bromelain helps you keep joint tissues healthy from over-stress from day-to-day use.

10. On-the-go gut health supplement: Benefiber on the Go

This on-the-go product makes it really easy to add fiber to your food or drink while on the go. It’s one of the top vitamin brands for digestive health.

The plant-based prebiotic fiber easily dissolves into food and drink. And even though the this supplement contains wheat dextrin, the product is gluten free.

container of apple cider vinegar supplement

11. Blood sugar control supplement: Bragg Apple Cider Vinegar Capsules

Bragg just came out with apple cider vinegar capsules, and the company did a good amount of research before creating this product that has a clinically effective dose of acetic acid in a serving size of three capsules.

As well, the product contains 1,200 IU vitamin D and 13 milligrams of zinc.

bottle of magnesium L-threonate

12. Brain health supplement: Magtein Magnesium L Threonate

Magnesium L-threonate is a specific type of magnesium that’s been proven to have cognitive benefits. It was discovered by MIT researchers, and you can get it in supplement form.

Research suggests that it may help improve brain plasticity. This can have positive effects on memory, learning, and cognition.

bottle of Life Extension vitamins D and K

13. Vegetarian supplement: Life Extension Vitamins D and K with Sea Iodine

Vitamin D doesn’t come from many food sources, and some of the best ones are animal based. Vitamin D and vitamin K work in synergy, so it’s best to take them together.

And iodine is great for vegetarians because seafood is one of its top food sources (besides iodized salt), and taking a supplement helps you meet your recommended daily amount. Iron works with your red blood cells to keep your blood oxygenated.

Final thoughts

With the proper know-how, you can easily find the best vitamin brands for you and your family. You will want to make sure any supplement that you buy is third-party tested to ensure that you are purchasing a quality product.
