Buyer Beware

Dietary supplements do not fit into the category of drug and therefore, the safety requirements are not as stringent. Manufacturers notoriously cut corners whenever possible for a leg up on their rivals.

Filling this need, third-party companies evaluate products for effectiveness and safety.

Every year new headlines come out about contaminated supplements. The results of many such tests are dismal.

A study on athletes found that supplement users unintentionally consumed products adulterated with banned substances. This devastated the career of Olympic swimmer Jessica Hardy. And Jessica was proactive. Before buying, she had contacted the company for safety and purity information on their products. 

One of the larger tests of 138 common dietary supplements found worrisome levels of toxic molds, yeast, and fungi.

Another more recent 2018 study identified unapproved pharmaceutical ingredients in a staggering 776 dietary supplements. What kind of products? Those marketed for sexual enhancement, weight loss, or muscle building. 

In June 2019 the FDA seized 300,000 containers of contaminated products.

Due to widespread product contamination and new untested brands bombarding store shelves, choosing a safe and reliable supplement brand is critical to your health and wellbeing.

How do you ensure the quality of the supplement?

When researching the best vitamin brands, we considered the following factors:

– Third-party testing (for instance, NSF International, Consumer Lab, and the United States Pharmacopeia) (USP). We looked for brands that have been tested by an independent lab to guarantee they were free of contaminants such as heavy metals or microbes.

– Certifications. We looked for brands offering products with additional certifications, such as NSF Certified Safe for SportNon-GMO Verified, or certified gluten-free or vegan.

– Ingredients. We chose brands that prioritize the use of high quality ingredients and easily absorbed forms of vitamins and minerals. We prefer brands that avoid or limit the use of artificial flavors, fillers, and preservatives.

– Price. Be aware if the supplement is a lot cheaper than others, there might be a reason behind it. Check for third-party testing or certification.
– Dose. Making sure that the supplement is in an amount that has clinically therapeutic. Some supplement offer higher dose that may be dangerous. Best to talk to your doctor if you decide to take a higher dose.

- Are Thorne’s products certified nonGMO?

Thorne has a longstanding policy to not use genetically modified ingredients in our products. Therefore, to the best of our knowledge, every Thorne product is GMO-free, even though we don’t label our products as being non-GMO. The reason we don’t label our products as non-GMO is because there are no current tests that can be performed to confirm an ingredient’s non-GMO status. Currently, an ingredient’s non-GMO status can only be affirmed by a supplier affidavit, and Thorne has chosen to wait for the time we can use scientific methods to confirm every ingredient’s non-GMO status.
