Astaxanthin Effects on Osteoarthritis Associated Pain and Inflammatory Indicators

This study is intended to assess the effects of astaxanthin use on pain, physical function, and inflammation as reflected by Patient-Reported Outcomes Measurement Information System (PROMIS) scores and levels of inflammatory biomarkers in subjects taking astaxanthin. If improvements in pain, function, and/or markers of inflammation could be demonstrated with the use of astaxanthin, this may suggest the potential for astaxanthin to be used in management of knee osteoarthritis (and possibly other forms of osteoarthritis) with less evident toxicity than seen with the presently available standard therapies (e.g. NSAIDS, opioids).
