Thorne Supplements: The only one with TGA certification
Ever since January 2000, Thorne has been TGA certified. The Australian TGA is considered the most stringent pharmaceutical regulatory body.
Pharmaceutical purity
Thorne uses only ingredients of pharmaceutical purity. They produce supplements in capsules and in powder form. This guarantees very good absorption. And Thorne uses no additives such as stearates, binders, disintegrants, coatings, preservatives and unwanted fillers.
Stringent raw material testing
Thorne Research has complete control over all manufacturing processes. From procurement of raw materials to shipment of finished products. Thorne has its own research laboratories and tests each batch when all raw materials arrive. In addition, a round of testing takes place during production and again after production. The product stability of each batch is also tested. So we are talking about 4 rounds of testing!
World's most hypoallergenic vitamins
Thorne Research products are distinguished by purity, potency and their hypoallergenic properties. Thorne supplements are the most hypoallergenic supplements in the world. To give an example: The vitamin E products Thorne produces from soy are so highly purified that even people with soy allergies can use them without any problems..
100% GMO-free
Thorne Research partners with the Non-GMO Project, a nonprofit organization that verifies that products and ingredients are guaranteed to be free of genetically modified organisms. All of Thorne's products are GMO-free.
Healthy Aging
Thorne has been increasingly focusing its product line and information on prevention in recent years when it comes to staying healthy. A common term for this is Healthy aging. Healthy aging is not about covering up signs of aging like wrinkles or gray hair, but about going through life healthy and feeling good whether you are 20, 40, 60 or 80."
Lifestyle
This depends not only on your genes, but also to a large extent on your lifestyle: adequate exercise, healthy eating and good sleep are factors you can control yourself. And when that is not always possible, there are supplements that can contribute to this.
Supplement support
Thorne has developed a number of supplements that help keep the body and mind active so that our biological age remains as young as possible for as long as possible. Many of these products have unique formulas, combinations of the most valuable ingredients in optimal dosages.
