Our Supplements

Are Thorne's nutritional supplement products hypoallergenic?

Thorne strives to purchase the highest quality ingredients, and we don't use ingredients that contain hidden allergens.

What is the best way to store Thorne supplements?

Unless otherwise indicated on the product label, Thorne recommends that its products be stored tightly sealed in a cool, dry place, such as a pantry or cabinet. Products should be kept away from a location exposed to moisture (such as a bathroom) or heat (such as above the stove).

Be sure your hands are dry before handling your supplements and whenever possible, store the product in the bottle it came in and keep the lid tightly closed. Placing the contents of an entire bottle in a pill box or a baggie might cause the product to discolour or otherwise change in appearance.

Does Thorne use fillers?

Most nutritional supplements contain excipients that contribute functional or structural properties, such as fillers, binders, and lubricants.

At Thorne, we minimize the use of these “Other Ingredients” and we refuse to include unnecessary excipients that can interfere with dissolution, or absorption, or otherwise detract from the optimal use of the product.

Every ingredient in a Thorne product, including the “Other Ingredients,” are sourced from the purest sources possible. Each ingredient is scrutinized and preference is given to ingredients that are free of contaminants and minimize allergens. Thorne believes in total label transparency. That means there are no hidden inactive ingredients. Every ingredient in a Thorne product, whether active or inactive, is listed on the product label.

Can I take Thorne supplements with my medications?

For medication/supplement interactions we know about, we note them on the product label and our website.

However, there is always a possibility that you could have an individual reaction to taking a particular medication and a particular nutritional supplement at the same time. Therefore, we always advise that you consult with a qualified health-care practitioner – preferably the one who prescribed or recommended your medication – before you begin taking a nutritional supplement at the same time.

Do you test your products for hot and cold stability?

Before we launch a new product, we subject it to accelerated stability testing. This testing subjects the product for 90 days to heat (40° C / 104° F) and 75-percent relative humidity. The product formula must demonstrate stability at the conclusion of this testing. If the formula fails this testing, then the product is reformulated and the accelerated stability testing is conducted on the new formula.

Are your products natural or synthetic?

Although the ingredients in Thorne's nutritional supplement products are not derived from whole foods, many are derived from natural sources.

Some ingredients are fermented and some are synthesized, and we select every ingredient for being in its most absorbable and usable form. These synthetic nutrients are bio-identical and used by the body in the same way as naturally derived ingredients – whether natural or synthetic – and every ingredient is tested to ensure it meets its specifications for identity, purity, and potency.

Are your probiotic products stable?

Yes. Thorne's probiotic products are stable and do not require refrigeration. Thorne periodically tests retained samples of each probiotic product throughout the product's shelf life to ensure the products remain stable and meet label claims at the expiration date.

How do you avoid cross-contamination of other products when a Thorne product contains an ingredient that is a known allergen?

After Thorne manufactures a product that contains a known allergen, we perform comprehensive cleaning procedures that remove all allergenic protein from the production area. After this cleaning is completed, the entire room and the equipment in it are tested for the allergen to verify there is no allergen protein remaining. This ensures there will be no cross-contamination between ingredients that do contain known allergens and those that do not.

What makes Thorne decide to reformulate a product?

Although reformulating a product can occur for a number of reasons, the most common reason is that new research shows that a different formulation will enhance the product's benefits.

Other reasons include a particular ingredient no longer being available or Thorne's inability to source an ingredient that meets our purity specification for it, in which case a reformulation is necessary to replace or remove that ingredient from the formula.

Why does a Thorne product sometimes change color?

Color variance is normal for some products, especially products that have botanical ingredients.

One reason for color variance is that Thorne does not use unnecessary fillers that are typically used to keep products uniform in appearance. So for a natural ingredient, depending on the time of year it was grown and harvested, color variance is not uncommon; for example, a botanical ingredient can be bright yellow in one lot and pale yellow in the next lot.

Color changes can also occur as a result of changing the product's formula or changing the raw material supplier. However, if you have a particular concern about a product's color or appearance, then please contact us.

Is Thorne regulated by the FDA?

Thorne is regulated by the U.S. Food and Drug Administration. Thorne must comply with the FDA's regulations for manufacturing and labeling our dietary supplement products.

The FDA also requires Thorne to label the presence of allergens and to respond properly to reported adverse events.

Is Thorne regulated by the HSA in Singapore?

Yes, all of our products have been submitted to HSA (Health Sciences Authority) for approval before it is sold on our online store.

Are Thorne products certified organic?

Although many of the ingredients in Thorne products are organic, Thorne products themselves are not certified as organic.

Does Thorne test its products on animals?

No. Furthermore, Thorne supports the objective of eliminating the laboratory testing of all animals.

I have a Thorne product that has expired. Can I still use it?

We don’t recommend using a Thorne product after its expiration date.

Thorne conducts stability testing on our products, which ensures the potency of every ingredient at the product’s expiration date. Because of our stability testing program, Thorne can guarantee that its products meet 100 percent of the product's label claims up to the time of expiration.

Although we don’t recommend using a product after its expiration date, it certainly won't harm you if you do use it. It doesn't mean the product has "gone bad" – it just means one or more of the ingredients might be at less than 100 percent potency.

Can your products be taken out of the capsule to take them?

Most Thorne products can be taken out of their two-piece, pull-apart capsule. However, there are several products that we don't recommend taking out of the capsule, and this recommendation is indicated in the “Warnings” section on the webpage for the applicable products.

What should I do if I think I'm having a reaction to a Thorne product?

If you are experiencing a reaction from any of our products, please discontinue using the product immediately and contact your general practitioner or an emergency medical center.
