About this study

The purpose of this clinical study was to determine whether gold nanoparticles (AuNP) supplement holds clinical value in improving knee joint health, function, and quality of life for arthritis patients. A total of 51 participants were followed for 20 weeks through a three phase longitudinal study. Both subjective and objective parameters were used to measure and monitor changes in knee joint health and function, as well as quality of life.

Treatment and study plan

Gold Factor (Gold Nanoparticles, AuNPs)

Dietary Supplement

AuNP used in the study is an aqueous suspension of clean-surfaced, faceted gold nanoparticles that have extraordinary catalytic capabilities. AuNP were 8 - 28 nm in diameter, with varying shapes from bipyramids to polyhedrons. To avoid contamination, AuNP was suspended in ultra-pure water, and were not coated with any proteins or molecules to avoid negative reactions within living tissues. This resulted in a rose-pink color due to the incident light inducing a specific resonance known as the localized surface plasmon resonance. The AuNP supplement used in this study contains elemental gold at 6 ppm. Study dosage is 1 oz per day, which is about 0.17 mg elemental gold per day.

Other names: AuNP Supplement

Placebo

Dietary Supplement

For the Placebo, water and red dye were mixed to create a placebo liquid with the same rose-pink shade as the AuNP supplement, along with flavoring that matched the AuNP supplement.

Primary outcomes

  1. Knee injury and Osteoarthritis Outcome Score (KOOS): Pain score

    Time frame: 20 weeks

    The KOOS survey was chosen due to its repeatability, and it gave scores of 0-100 for four separate categories: Symptoms, Pain, Function & Daily Living, Sports & Recreational Activities, and Quality of Life. Under KOOS scoring guidelines, a score of zero represents extreme knee problems, and 100 represents complete function of the knee with no pain, discomfort, or other joint related problems.

  2. Knee injury and Osteoarthritis Outcome Score (KOOS): Symptoms score

    Time frame: 20 weeks

    The KOOS survey was chosen due to its repeatability, and it gave scores of 0-100 for four separate categories: Symptoms, Pain, Function & Daily Living, Sports & Recreational Activities, and Quality of Life. Under KOOS scoring guidelines, a score of zero represents extreme knee problems, and 100 represents complete function of the knee with no pain, discomfort, or other joint related problems.

  3. Knee injury and Osteoarthritis Outcome Score (KOOS): Function in Activities of Daily Living (ADL) score

    Time frame: 20 weeks

    The KOOS survey was chosen due to its repeatability, and it gave scores of 0-100 for four separate categories: Symptoms, Pain, Function & Daily Living, Sports & Recreational Activities, and Quality of Life. Under KOOS scoring guidelines, a score of zero represents extreme knee problems, and 100 represents complete function of the knee with no pain, discomfort, or other joint related problems.

  4. Knee injury and Osteoarthritis Outcome Score (KOOS): Function in Sports and Recreation score

    Time frame: 20 weeks

    The KOOS survey was chosen due to its repeatability, and it gave scores of 0-100 for four separate categories: Symptoms, Pain, Function & Daily Living, Sports & Recreational Activities, and Quality of Life. Under KOOS scoring guidelines, a score of zero represents extreme knee problems, and 100 represents complete function of the knee with no pain, discomfort, or other joint related problems.

  5. Knee injury and Osteoarthritis Outcome Score (KOOS): Quality of Life score

    Time frame: 20 weeks

    The KOOS survey was chosen due to its repeatability, and it gave scores of 0-100 for four separate categories: Symptoms, Pain, Function & Daily Living, Sports & Recreational Activities, and Quality of Life. Under KOOS scoring guidelines, a score of zero represents extreme knee problems, and 100 represents complete function of the knee with no pain, discomfort, or other joint related problems.

  6. C-Reactive Protein

    Time frame: 20 weeks

    C-Reactive Protein levels were measured at T0 for baseline scores, and then measured again at T1, T2, and T3. As CRP levels are biomarkers of systemic inflammation, it was expected to see a decrease in CRP levels when taking AuNP Supplement.

  7. Range of Motion Bilateral Flexion score

    Time frame: 20 weeks

    All participants completed a physical assessment conducted by an assigned physical therapist: Range of Motion Bilateral Flexion, Leg Press, Walk Test, Sit-to Stand and Single Leg Squats.

  8. Leg Press repetition number

    Time frame: 20 weeks

    All participants completed a physical assessment conducted by an assigned physical therapist: Range of Motion Bilateral Flexion, Leg Press, Walk Test, Sit-to Stand and Single Leg Squats.

  9. 6-minute Walk distance (meter)

    Time frame: 20 weeks

    All participants completed a physical assessment conducted by an assigned physical therapist: Range of Motion Bilateral Flexion, Leg Press, Walk Test, Sit-to Stand and Single Leg Squats.

  10. Sit-to Stand repetition number

    Time frame: 20 weeks

    All participants completed a physical assessment conducted by an assigned physical therapist: Range of Motion Bilateral Flexion, Leg Press, Walk Test, Sit-to Stand and Single Leg Squats.

  11. Single Leg Squats repetition number

    Time frame: 20 weeks

    All participants completed a physical assessment conducted by an assigned physical therapist: Range of Motion Bilateral Flexion, Leg Press, Walk Test, Sit-to Stand and Single Leg Squats.
