TriFlex is a natural supplement that is said to promote joint health. It is made by the company GNC, a very well-known manufacturer of health and wellness products who have been in business for over 80 years and have numerous retail locations in addition to their online store. Described as being ‘fast-acting’, this particular joint supplement contains several commonly used joint health ingredients such as Glucosamine and Chondroitin, plus MSM, Turmeric and the patented substance ApresFlex. A form of Boswellia Serrata, ApresFlex has been clinically proven to relieve joint discomfort and stiffness within 5 days and, as with all the ingredients in the formula, is included in a clinical strength dose, according to the manufacturer. While the ingredients are listed on the TriFlex product label, they’re not explained in much detail and there is no clinical testing data shown on the website.
