Gold Factor on Knee Joint Health and Function

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.

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.
