Thorne supplements are good quality, though they may be a little pricier than some other brands.

Whether you’re looking to improve your health, reach your fitness goals, or simply squeeze more nutrients into your daily diet, supplements are often considered a convenient solution.

In a survey from the Centers for Disease Control and Prevention (CDC) based on data from 2017 and 2018, nearly 58% of U.S. adults reported using dietary supplements within the past 30 days.

However, with so many vitamin brands on the market, finding a reputable retailer can be incredibly challenging.

In fact, apart from checking out a brand’s prices and product selection, there are many other factors to consider, including how the company sources ingredients, where its supplements are manufactured, and whether the products have any certifications or are third-party tested.

Thorne is one of the most well-known supplement manufacturers. This brand offers a massive selection of supplements aimed at addressing a variety of health concerns, ranging from maximizing sports performance to maintaining liver or lung health.

Still, despite the brand’s good reputation and widespread popularity, many people may wonder whether Thorne products are worth the price.

This article will take an in-depth look at Thorne, including its products, its reputation, and how it stacks up against competitors.

Since it was founded in 1984, Thorne has been on a mission to revolutionize the supplement industry and empower customers to take control of their health by providing a variety of supplements formulated with clinically proven ingredients.

Though it started with a single product, the company now offers a wide selection of supplements, including multivitamins, probiotics, protein powders, and at-home test kits.

All supplements from Thorne are free of gluten and unnecessary fillers, additives, and artificial ingredients.

The supplements are also manufactured in a facility that is certified by third-party organizations such as NSF International and the Therapeutic Goods Administration (TGA), which is Australia’s regulatory agency responsible for evaluating the safety of supplements.

According to Thorne, ingredients are sourced from trusted suppliers to ensure quality, and all products are tested in the company’s in-house laboratory multiple times throughout the manufacturing process.

Though the company doesn’t include details on whether supplements are also tested by an independent lab, it does offer more than 20 products that are NSF Certified for Sport, meaning those products have been screened to ensure they’re free of substances banned for athletes.

This is an important consideration when purchasing supplements, as third-party testing can ensure that products are high quality, safe, and free of harmful contaminants such as heavy metals and pesticides.

Here are a few of the pros and cons to consider before trying Thorne.


  • The brand offers a wide selection of products.
  • The manufacturing facilities are third-party certified.
  • Some products are NSF Certified for Sport.
  • All supplements are free of gluten and artificial fillers, dyes, and additives.


  • It’s more expensive than some similar brands.
  • Not all products are third-party tested.
  • Many supplements are not suitable for certain dietary restrictions, including vegan and vegetarian diets.

With more than 180 supplements and bundles to choose from on its website, Thorne offers options catering to a variety of health needs and goals.

In addition to products intended to support general health or fill in any gaps your diet, such as multivitamins and protein powders, Thorne offers supplements specifically for certain health needs, including:

With so many supplements available, Thorne might be a good option for people who are looking to improve their health or increase their intake of certain nutrients through supplements.

Many of the sports supplements are also screened for banned substances and NSF Certified for Sport, which may be a key consideration for athletes.

However, certain products may be more expensive than similar supplements from comparable brands, which might mean Thorne products are not a good fit if you’re looking for budget-friendly options.

Thorne offers a variety of supplements, including many products tailored to specific health needs and conditions. Here’s a closer look at a few popular Thorne products, including a couple we tested for ourselves.

Thorne provided free products for testing. But our opinions, reviews, and recommendations are ours alone and have not been reviewed, approved, or otherwise endorsed by Thorne.

Thorne is known for quality and has collaborated with many manufacturers, researchers, and health organizations around the globe.

Limited customer reviews are available on the company’s website, but there are thousands of reviews for various Thorne products on other websites, such as Amazon.

Products are generally well rated. For example, Thorne Creatine holds a 4.6/5-star rating on Amazon, and Basic Nutrients 2/Day has a rating of 4.4/5 stars.

Though Thorne is not accredited by the Better Business Bureau (BBB), it currently has an A+ rating from the organization.

This is determined by considering factors such as the company’s complaint history, its business practices, how long it has been operating, and whether there are any issues related to advertising, licensing, or government actions.

Generally, customer complaints about the brand that have been reported to the BBB are related to issues with refunds, order cancellations, and delivery delays, though most have been resolved.

Thorne products are formulated using ingredients that have been extensively studied for their safety and potential health benefits.

In fact, the brand provides detailed information on the ingredients in each product and their effects on health, along with any drug interactions or contraindications that you should be aware of.

Additionally, Thorne has partnered with organizations and research institutes such as the National Institutes of Health, Mayo Clinic, and Columbia University to test its products.

According to the company’s website, more than 40 of its products have been used in clinical trials conducted around the world.

However, Thorne does not specify whether its products are featured in any published or peer-reviewed studies.

For best results, be sure to use supplements as directed. For example, some supplements, such as Mood Plus and Basic Prenatal, need to be taken with food to maximize absorption or prevent side effects, while others can be taken on an empty stomach.

Taking more than the recommended dose of certain products over long periods — including those that contain iron or fat-soluble vitamins such as vitamins A, D, E, and K — may also lead to very serious side effects.

Additionally, it’s important to consult a healthcare professional before adding any supplements to your routine, especially if you have any underlying health conditions or are taking medications.

A professional can help ensure that supplements don’t interact with any medications you may be taking and can recommend an appropriate dosage to meet your needs.

Unlike medications, supplements do not require approval from the Food and Drug Administration (FDA), and the FDA does not evaluate supplements for safety or effectiveness.

However, Thorne notes that it complies with all FDA regulations for manufacturing and labeling, and its products are manufactured in facilities certified by other third-party organizations, including the TGA and NSF International.

Thorne offers Collagen Plus, a supplement that features collagen peptides and is designed to slow signs of aging and promote skin and hair health.

Most Thorne products are manufactured in the company’s facility in Summerville, South Carolina, though ingredients may be sourced from around the globe.

Although Thorne products may be more expensive than those from some competitors, the supplements are high quality and are made using clinically proven ingredients.

However, while all Thorne products are tested in-house, keep in mind that only those that are NSF Certified for Sport are tested by an independent lab. This may be an important consideration, as third-party testing can help ensure the safety and quality of supplements.

Thorne Research is a reputable supplement company that produces high quality supplements tailored to a wide range of health needs.

However, only select Thorne supplements are third-party tested, which may be an important consideration for some people. Furthermore, some of the products can be pricey, and many are not suitable for those with certain dietary restrictions, such as vegans or vegetarians.

Still, with more than 180 supplements and bundles available, Thorne offers products designed to help you reach your health goals or increase your intake of the nutrients that matter most to you.
