Supports healthy circulation, immunity, and elimination;Proteolytic Enzyme Blend. Optimal circulation is dependent upon the presence of effective proteolytic enzymes.* Endo/exo peptidases are known to break the inner/terminal bonds of amino acid chains for more efficient hydrolysis of proteins. The highly active systemic enzymes included in this formula have a wide range of pH stability (3.0 pH - 10.0 pH) which is essential for maximum benefit
