Trusted Manufacturer

For more than 30 years, Thorne has been trusted by health-care practitioners who prescribe our products to their patients. In addition, our products are now recommended by U.S. National Teams and multiple professional sports teams for their elite athletes. Thorne products are a testament to Thorne's mission to provide high-quality supplements that are tested for quality, safety, and efficacy.

Purest Ingredients

There are no unnecessary fillers or additives in Thorne supplements. Thorne is committed to providing high-quality supplements that contain research-backed ingredients, in efficacious amounts, that retain the potency to meet label claims until the day of expiration.

Bone Support

The gut isn’t just the stomach. The gut is the entire digestive tract and is a complex mix of organs, microbes, hormones, and enzymes. How this complex mix of organs interacts dictates how well your body will absorb the foods you eat. So what happens or doesn’t happen in your gut will inevitably impact your daily health and wellbeing.

Because the digestive tract delivers to our bodies the nutrients we eat, there are many measures we can take to be certain we are reaping the full reward from these nutrients in terms of absorption, especially if someone is prone to gas, bloating, acid reflux, constipation, or other distress after eating.

Optimal functioning of the gastrointestinal tract is vital for nutrient absorption, nutrient synthesis, the production of short-chain fatty acids for colon health, the elimination of waste, and proper immune function. An unhealthy diet, insufficient digestive enzymes, and taking various prescription and over-the-counter medications can cause imbalances in the gut flora. That’s why supplementation is important, and it's why Thorne offers well-researched, high-quality supplements that support a healthy gut.*

Innovative Solutions

When the highest standards have been met, Thorne creates higher ones.

Sourcing Exceptional Ingredients

We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health.

Manufacturing the Right Way

We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, South Carolina, manufacturing facility is annually certified by GMP and certified by NSF International yearly, a well-recognized independent third-party certification organization.

Four Rounds of Testing

We perform four rounds of testing for each product we manufacture – far above the industry standard. Thorne has invested in two state-of-the-art in-house laboratories that enable us to conduct four rounds of testing, including raw material testing, in-process batch testing, finished product testing, and expiration date stability testing for each lot of product that we manufacture.

Thinking Sustainably

We're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards.


Focus on sustainability

Compact by design from Climate pledge friendly. Certified by Amazon.

Small changes in product size & weight lead to lower carbon emissions.

At scale, these small differences in product size and weight lead to significant carbon emission reductions.

Here are a few of the many ways products can qualify:

Less packaging

Less air in container

More efficient shape

Waterless technology

It's not expired! That's the date of manufacture!
5 Stars
It's not expired! That's the date of manufacture!
This product is helping me to release excess yeast and so far seems very potent. A lot of customers are leaving poor reviews saying the expiration date is from 2019 but that is actually the date it was manufactured (MFG) so the sticker expiration date is correct. I contacted Thorne directly to ask about whether or not to take with food. They said at first it's best taken with some food such as crackers (Not exactly on the candida diet but whatevs) in the beginning until your body adjusts to the supplement. You don't necessarily have to take it with a meal but that may be a good approach when introducing the undecylenic acid. Hope this helps!
