None of Thorne Research’s nutritional supplements contain potentially allergenic fillers, binders, or lubricants.

Practitioners rely on Thorne as the company they trust for their extremely allergic, chemically sensitive, and immune-compromised patients.
Purity Takes Extra Effort.
For example, instead of purchasing prediluted vitamin D, as other companies do, Thorne performs its own dilution to avoid detrimental ingredients, such as the preservatives or lactose that are found in many commercially available dilutions. Why must vitamin D be diluted? Because in its pure form, it is too concentrated to safely blend into a vitamin product. Pure vitamin D is 40 MILLION International Units (IU) per gram. The RDA is 400 IU per day.
To ensure proper mixing, it must be made into a dilute powder that flows and does not lose potency. So, unlike companies that use prediluted vitamin D with unacceptable excipients and preservatives, at Thorne, pure pharmaceutical vitamin D is first gently melted with pure mixed tocopherol vitamin E, and the resultant stable vitamin D is then blended with hypoallergenic magnesium citrate powder. The resulting powder is then run through a high-speed mill while liquid nitrogen is injected to eliminate heat and stickiness. The final powder is blended again in a large tumble blender and subsequently analyzed. Not only is the final product stable; it is also hypoallergenic and can be mixed homogeneously and at a safe level with other powders. Just as with vitamin D, Thorne utilizes similar processes for other raw materials, such as vitamin K, leaving it to other companies to purchase commercially available raw materials filled with unacceptable ingredients and preservatives.
