Thorne Research FAQs

Do any of your products contain shellfish, rice, gluten, corn, wheat, dairy, soy, yeast or nuts?
None of Thorne's products contain corn, wheat, nuts, or gluten. A few of their products have ingredients derived from a shellfish source, and a few products do contain rice, dairy, soy, or yeast. These allergens are clearly indicated on the product labels and in the product labeling and warnings on Thorne's website.

Are your capsules vegetarian?
All our two-piece capsules are made from plant-derived cellulose.

What is the difference between aspartate, citrate, citramate, and picolinate?
Minerals can be chemically bonded with organic acids or amino acids to improve their absorption in the body. Citrate, citrate-malate (Citramate), picolinate, and glycinates are used by Thorne Research for this purpose. Macrominerals such as calcium, magnesium, and potassium, are best absorbed when reacted with citrate-malate, while trace minerals & iron, zinc, chromium, copper, and molybdenum – appear to be best absorbed when reacted with picolinate, glycinate, or bisglycinate. Thorne still offers citrate minerals, as many health-care practitioners have been using these products for a long time, and some patients may respond better to these mineral forms.

What is the best way to store your products? Do any products require refrigeration?
Thorne recommends that most of their products be stored tightly sealed in a cool, dry place. A few products need to be refrigerated, which is clearly indicated on the label.

What fillers do you use in your products and where do they come from?
When it is necessary to fill the capsule with something in addition to a nutrient or botanical, Thorne uses magnesium citrate, cellulose, magnesium citrate-laurate, or silica. Magnesium citrate is the pure element reacted with pure citric acid; cellulose is pure plant fiber (usually from pine trees), magnesium citrate-laurate is the pure element reacted with citric acid and lauric acid (a small fat molecule that does not inhibit absorption), and silica is the pure element found in sand.

Do you test for heavy metals in your fish oil products?
The fish oil ingredient is tested for heavy metals and other contaminants when they receive it and before they use it in a product.

Will radiation or exposure to extreme cold or heat damage my product?
Ionizing radiation can damage any nutrient or botanical. Thorne products are very stable and will not degrade if exposed to moderate variations of heat or cold.

Are your products GMO-free?
Thorne Research, Inc. does not make any products that contain Genetically Modified Organisms (known as GMOs).

It will always be the policy of Thorne Research to be sensitive to public health-related issues raised by our health-care practitioner-customers. One such issue is the presence of GMOs in our environment and especially in our food and food-related products, such as nutritional supplements consumed to promote good health. This requires that Thorne closely analyzes and examines the dietary ingredients they use to manufacture their nutritional supplements to be absolutely certain these ingredients are not derived from GMO sources nor that they utilize GMOs in their production.

Are your products certified organic?
No, they are not.

Are any of your products Certified Kosher?
No; however, since health-care practitioners usually prescribe Thorne products they can be considered medicine and can be taken as such.
