|1 Solubility of copper, iron, manganese, and zinc at intestinal pH (7.0–7.2). Solubility for Melaleuca’s form was determined
as percent of ingredient remaining in solution at pH 7.0 after being at pH 1.0 (stomach conditions). Competitors’
ingredients solubility data taken from Merck Index and Handbook of Chemistry and Physics.
2 Inorganic forms of copper is defined as 100% rate of free radical generation (determined as a result of free radical
oxidation of 2’,7’-dichlorofluorescein catalyzed by different forms of copper).
* When tested against the sulfate, gluconate, oxide, and fumarate forms of copper, iron, manganese, and zinc (the forms
commonly used by almost all commercially marketed nutritional supplements) at intestinal conditions.
