Veterinarians have become accustomed to seeing the vague "We use only the purest ingredients" in the promotional materials of almost every animal health product company. Perhaps these companies truly believe that. Perhaps they don't know any better. Nevertheless, Thorne Research, for more than 25 years, is the standard by which companies in the industry are judged for product purity. Veterinarians can rely on Thorne Vet as the company they trust for their allergic, chemically sensitive, or immune-compromised patients.
Purity Takes Extra EffortFor 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. 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 that contain unacceptable excipients and preservatives, at Thorne, pure pharmaceutical vitamin D is first blended with pure mixed tocopherol vitamin E, and the resultant stable vitamin D is then blended with hypoallergenic cellulose powder. The final powder is blended 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.
Ingredients You Don't WantMagnesium Stearate: Good for speed-hungry encapsulating machines. Not necessarily good for animals. Manufacturing encapsulated products isn't easy. Pure powdered ingredients are difficult to mix because they are either extremely dry, sticky with botanical oils, or attract unwanted moisture. So most manufacturers add magnesium stearate and other agents such as lactose and dextrose to make the powder flow quickly and easily through their high-volume machines. Problem is, these additives may compromise the bioavailability of the nutrients in the product, and might cause allergenic problems. At Thorne Vet, we take a different approach.
Thorne Vet will never utilize large fatty acid excipients in its manufacturing processes – ingredients such as magnesium stearate or stearic acid. These excipients are utilized as flowing agents to ensure that maximum productivity is obtained from capsuling and tableting machines. There are documented detrimental effects directly attributed to long chain fatty acids utilized as manufacturing flowing agents. Every qualified pharmaceutical compounder recognizes that large fatty acids, such as magnesium stearate, can interfere with product dissolution and influence absorption. Virtually all companies, because of the economic impact, ignore this data. As with most industries, the bottom line dictates the level of quality. The animal health product industry has one exception: Thorne Vet does not compromise. If a company cannot manufacture products without using detrimental excipients, they should not allude to being either "hypoallergenic" or "pure."
The Bottom Line?Thorne Vet is the only hypoallergenic animal health product manufacturer with the highest degree of purity that you – and your allergic, chemically sensitive, or immune-compromised patients – can truly trust.
