Thorne Whey Protein Isolate Dietary Supplement FAQs

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). And 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 discolor 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?

Many Thorne customers who take prescription or over-the-counter medications want to know if nutritional supplements can be taken at the same time. 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.
