Primary outcomes

  1. percentage of participants who are randomized to the study out of all participants approached

    Time frame: 8 weeks

  2. percentage of participants who start the intervention who go on to complete the 8-week or 16-week intervention

    Time frame: 16 weeks

  3. percentage of participants who take at least 80% of the fucoidan pills during the study

    Time frame: 8 weeks

Secondary outcomes

  1. mean change in Brief Fatigue Inventory

    Time frame: baseline to 16 weeks

    The Brief Fatigue Inventory is a 9-item questionnaire that ranges from 0 to 10 with higher scores indicating a worse outcome.

  2. mean change in plasma viscosity in blood

    Time frame: baseline to 16 weeks

  3. mean change in erythrocyte sedimentation rate in blood

    Time frame: baseline to 16 weeks

  4. mean change in thyroid stimulating hormone in blood

    Time frame: baseline to 16 weeks

  5. mean change in C-reactive protein in blood

    Time frame: baseline to 16 weeks

  6. mean change in leptin in blood

    Time frame: baseline to 16 weeks

  7. mean change in D Dimer in blood

    Time frame: baseline to 16 weeks

  8. mean change in TNF alpha in blood

    Time frame: baseline to 16 weeks

  9. mean change in neopterin in blood

    Time frame: baseline to 16 weeks

  10. mean change in lactase dehydrogenase in blood

    Time frame: baseline to 16 weeks

  11. mean change in procalcitonin in blood

    Time frame: baseline to 16 weeks

  12. mean change in frailty using a modified Fried's Frailty questionnaire

    Time frame: baseline to 16 weeks

    The modified Fried's Frailty questionnaire measures self-reported slowness, weakness, weight loss, physical activity and fatigue. The total score of the questionnaire ranges from 1 to 5 with higher numbers indicating worse outcome.
