This study is designed to evaluate the effectiveness of a proprietary nutritional supplement that contains Krill Oil (KO), astaxanthin (AX) and hyaluronic acid (HA) to reduce pain and discomfort in participants, compared to an inert placebo (palm oil) control and to a positive control (glucosamine-chondroitin). The purpose of the study is to determine if the combination of KO, AX, and HA will benefit participants with joint pain.
