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.


I recently interviewed registered dietitians and doctors from all over North America to find out about the supplements and vitamin companies they trust the most, including which ones they consider to be the highest quality supplement brands.


I wrote about 11 of those top supplement brands in an article on ReadersDigest.com. You'll find additional trusted vitamin brands below, too, including top vitamin companies. 


In my article, I go over the importance of choosing supplements certified or reviewed by third parties so you know that they're safe and effective, and I also highlight several of the highest-quality vitamin brands out there.


Wondering if you should take vitamins every day? Read on for my supplements guide and to find out the best supplements. 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 additional 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.

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.

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?

Try it: Ovega-3 Vegetarian

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.

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.

Try it: Now Foods Vitamin D3

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.


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

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!

Try it: Life Extension Complete B-Complex

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. 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.”

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.
