Thorne Research is a trustworthy and reputable vitamin supplement brand. It partners with various research organizations, such as the National Institutes of Health, the Mayo Clinic, and the Cleveland Clinic, and tests many of its products via clinical trials to ensure safety and efficacy. Thorne produces a variety of vitamin supplements, protein powders, collagen supplements, probiotics, omega-3s, and more.

Thorne supplements are made with quality ingredients that have been tested for contaminants. Many of Thorne’s products have the NSF Certified for Sport seal. This seal verifies that supplements are verified to have accurate ingredient amounts and are free from contaminants and substances prohibited for athletes. For competitive athletes, in particular, this is an important consideration when choosing a vitamin brand.

Thorne Creatine is one of our top creatine picks because it dissolves quickly and is easy to mix.

Vitamin Forms: Capsules, powders | Certifications: Some products are USP Verified and Clean Label Certified | Organic: No | Non-GMO: Yes

We love that Ritual plainly lists where all their ingredients come from, and they do internal and independent verification on their products. This means they are verified to have accurate ingredient labels and to be free of contaminants. Notably, Ritual’s Women’s Multivitamin is USP Verified, and the protein powder is Clean Label certified. When browsing their supplements online, you will find a list of each ingredient, including where it was sourced, the form of vitamin and mineral used, and why it has been included in the supplement.

We like their highly curated supplement offerings, which target the specific needs of different genders and stages of life. In addition to multivitamins, they offer Essential Protein Shake protein powder, which is one of our favorite vegan protein powders because it has just the right amount of sweetness and blends well in a smoothie. They also sell Synbiotic+, a single capsule combining pre-, pro-, and postbiotics to support gut health.

In addition to their extensive testing protocols, Rituals formulations and dosages are science-backed and developed by a team of doctors and registered dietitians, making them a trusted brand.

Ritual offers a single-purchase option and a monthly subscription that delivers supplements to your door making it a convenient, hassle-free option.

One easy way to make your supplement intake more enjoyable is to get them in gummy form. If you are not a fan of swallowing pills, try SmartyPants, a reputable vitamin brand that makes gummy vitamins as well as capsules. Some products are NSF Certified and have the Clean Label Project Purity Award. Their website explains their testing process, and you can find specific products with certifications, awards, and results from independent verification. 

The company has an organic line of vegetarian gummies, and their bottles are 100% recyclable. For every bottle of SmartyPants sold, the company makes a one-for-one nutrient grant to Vitamin Angels, an organization that provides supplements to at-risk populations worldwide. SmartyPants gummies do not contain any synthetic colors or artificial flavors, sweeteners, or preservatives, but they do have added sugars, so that is something to note if you need to monitor sugar intake.

Athletes who are vegetarian, vegan, female, or follow restrictive diets may be at greater risk of vitamin deficiencies. If you are a competitive athlete, choosing a vitamin brand that is independently verified to ensure your supplements are free of contaminants and banned substances is even more critical. 

That’s why we like Klean Athlete as a vitamin brand for athletes (and non-athletes, too). Every product Klean Athlete produces is NSF Certified for Sport, so you can rest assured that it is free of banned substances and contaminants. Klean Athlete is transparent about ingredient sourcing and lab testing. In addition to this stringent independent verification, its products are all made without artificial coloring, flavoring, or sweeteners.

You can shop by your sport on their website to find supplements that may be especially helpful to get the most out of your workouts and help you recover. In our testing, we liked Klean Athlete Klean Isolate for an unflavored protein powder that can be added to smoothies, baked goods, oatmeal, yogurt, etc. Klean Athlete Klean Creatine was also our favorite tested creatine powder because it dissolves quickly and doesn’t add any flavor.

Some HUM products marketed as beauty, weight loss, metabolism, and detox supplements may lack sufficient evidence compared to the supplements we mentioned above. If you are interested in taking any of these supplements, we recommend speaking to a healthcare provider first, particularly if you are pregnant, taking medications, or have a preexisting health condition.
