Influence of Instaflex Advanced Supplement on Joint Function

Completed · Not applicable · Has a placebo group

Conditions studied: Knee Discomfort

In brief

Joint discomfort is reported by 32% of U.S. adults, and increases with age. The knee is the most common site of joint discomfort regardless of age. Nearly half of people with knee joint discomfort use natural supplements to alleviate symptoms, but more research is needed to determine their effectiveness. In a previous study, we measured the effect of 8-weeks ingestion of a commercialized joint support dietary supplement (InstaflexTM Joint Support, Direct Digital, Charlotte, NC) compared to placebo on joint discomfort, stiffness, and function in adults with self-reported joint discomfort. This study will be repeated using Instaflex Advanced, with a longer 12-week time period. The Instaflex Advanced supplement includes six products: turmeric, resveratrol, Boswellia serrata, collagen, hyaluronic acid, and black pepper extract. This unique blend may improve joint function and increase mobility, but has not yet been tested in humans using a randomized, double-blinded, placebo-controlled research design. The primary purpose of this study is to assess the effect of 12-weeks ingestion of the Instaflex Advanced supplement compared to placebo in improving knee function in adults with self-reported knee joint discomfort.
