Brief Summary:
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).

Primary Outcome Measures :
  1. Change in PROMIS Numeric Rating Pain Scale [ Time Frame: 20 weeks ]
    Pain improvement in subjects is the primary outcome measure. The Patient Reported Outcomes Measurement Information Systems (PROMIS) Pain Intensity Scale 1a tool will be used. This scale ranges from 0-10, with 0 representing no pain and 10 representing the worst pain imaginable.

Secondary Outcome Measures :
  1. Change in PROMIS Pain interference score [ Time Frame: 20 weeks ]
    Reduction in pain interference is a secondary outcome measure. The Patient Reported Outcomes Measurement Information Systems (PROMIS) Pain Interference Short Form 6b will be used as the survey tool for pain interference. This is a set of 6 questions to assess the degree to which pain has interfered with daily activities. There are 5 levels of pain interference from 0 (none at all) to 5 (very much or always). The higher the score, the greater the pain interference.

  2. Change in PROMIS Physical function score [ Time Frame: 20 weeks ]
    Improvement in physical function is a secondary outcome measure. The PROMIS Physical Function Short Form 6b will be used as the survey tool for physical limitation. There are 5 levels of limitation to physical function from 0 (without any difficulty) to 5 (unable to do). The higher the score, the greater the limitation

  3. Change in Erythrocyte Sedimentation Rate [ Time Frame: 20 weeks ]
    Change in ESR (mm/hr)

  4. Change in C-reactive protein levels [ Time Frame: 20 weeks ]
    Change in CRP levels (mg/L)

  5. Change in Interleukin-6 levels [ Time Frame: 20 weeks ]
    Change in IL-6 levels (pg/mL)

  6. Change in Cartilage Oligomeric Matrix Protein levels [ Time Frame: 20 weeks ]
    Change in COMP levels (ng/mL)
