Pure & Powerful Supplements

Thorne Research has also partnered with such health authorities as The Mayo Clinic to develop clinical trials meant to help provide useful data on the effectiveness of supplements in addressing modern health concerns. They have also dedicated themselves to ensuring their manufacturing practices result in the highest quality supplements possible. Below you’ll find some examples of Thorne’s quality control practices that make us assert them as being one of the best vitamin and supplement brands in the world.

Quality Control

There are few supplement brands in the world with rigid quality guidelines and safety practices as Thorne. They maintain strict adherence to the FDA’s current Good Manufacturing Practices (cGMP) guidelines, even going so far as to register with third-party authorities such as NSF International. Thorne Research is also the first dietary supplement company to receive an A1 rating from Australia’s Therapeutic Goods Administration (also one of the few US-based companies within any industry!)

Ingredient Testing

Thorne has its own testing facilities which they are constantly optimizing. These facilities allow them expedited processing and continued pursuit of evolving their quality control practices. Many companies choose to outsource their ingredient testing to third parties. Third-party testing is essential to building consumer trust, but in-house testing is also important. When the two are combined, such as the case with Thorne’s QA practices, there’s an added layer of security for consumers. Here’s a brief outline of Thorne’s Quality Control process:

Step 1: Testing Raw Materials and Ingredients

When a manufacturer receives raw ingredients, it’s important to verify their identity and purity. Thorne tests to assure that their ingredients are what they claim to be and screen them for over 1000 contaminants!

Step 2: Formulation Process Testing

It’s important to test supplement formulations during the manufacturing process to assert potency and homogeneity. Unexpected formulation variations can occur and, if there are checks in place to detect them, inferiority could surface. Thorne tests their products during production to ensure the final products meet specifications.

Step 3: Final Product Testing

After a product has been formulated packaged for final shipment, Thorne conducts spot checks to ensure purity and formulation ratios are met. This is an extension of in-process checking and is an essential practice for asserting final quality standards.

Step 4: Stability Testing

Rather than relying on industry estimates for product shelf-lives, Thorne ensures their “best by” dates are derived from in-house testing and certification. That means that when you buy a Thorne Research product that says it’s good for another three months, you can believe it!

Social Responsibility

A common theme among their many attractive characteristics is Thorne’s going above-and-beyond what is legally required of them to sell supplements. A further illustration of such inherent nobility is their dedication to environmental preservation. Thorne has taken strides to help preserve the ecosystems from where their products are sourced as well as protecting the environment-at-large by lowering their carbon footprint. Many companies make such claims, but Thorne practices what they preach. For example, if Thorne discovers their sourcing of an ingredient may potentially lead to a plant becoming endangered—they stop making that product. That’s a serious dedication.

Popular Supplements

Thorne’s product catalog is huge and covers nearly any nutritional need one could imagine. Their supplements range from single-ingredient formulations to synergistic blends meant to optimize bioavailability and efficacy. Below you’ll find some examples of the incredible supplements Thorne makes and why we love them so much.

Basic B Complex

The Basic B Complex by Thorne is designed for maximized absorption. B Vitamins are a family of nutrients that are notorious for being poorly absorbed. Certain genetic variations, such as those in the MTHFR gene, make it difficult to metabolize some b vitamins. Thorne’s Basic B Complex makes considerations for this and provides optimized compounds such as Methylcobalamin, Pyridoxal 5′ Phosphate, and L-5 Methyltetrahydrofolate (L5-MTHF).

Vitamin D3 – 5000 IU

The Vitamin D3 by Thorne Research is an example of how simple this brand is capable of being. No nonsense and no gel caps for those that aren’t into that. This supplement provides 125mcg of Vitamin D3 (cholecalciferol) which is slightly 600% more than the Recommended Daily Allowance. Modern research suggests that previous assessments of these nutrients fall woefully short of accounting for our daily needs. Supplements such as this one have been formulated to address such issues.

Adrenal Cortex

Adrenal Cortex by Thorne is made from the adrenal tissue of cows and is packed with compounds known to support healthy metabolism and hormonal function. Hinted at by the name—this product is designed to help support the natural production of compounds known as corticosteroids. These compounds include glucocorticoids, mineralocorticoids, and ketosteroids. Each of these is known to be critical in supporting glucose metabolism and robust immune function.

Final Thoughts

Thorne Research is among the best vitamin and supplement brands on the market. Their supplements are formulated for optimal bioavailability and efficacy. Their insights into supplement manufacturing and ingredient quality have set the bar for quality within the industry.

Thorne has dedicated their company, continually, to producing products with consumers in mind. We admire them as a company and respect the products they produce. Many of the professionals we’ve had the pleasure of speaking with over the years have expressed similar opinions as well. If you’re looking for quality supplements, look no further than Thorne Research.
