Abstract
Abstract The levels of essential metals in the mammalian system can be precisely controlled by administering these metals in the form of exogenously synthesized coordination complexes of picolinic acid. The complexes are characterized by the following structural formula: <IMAGE> wherein M represents the metallic cation and n is equal to the cation's valence.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
62 words
A food composition for selectively supplementing essential metals in a mammalian diet and for facilitating absorption of said metals by the mammalian system comprising a food composition containing an effective amount of at least one exogenously synthesized essential metal picolinate complex characterized by the following structural formula: ##STR3## wherein M represents the metallic cation and n is equal to the cation's valence.
Claim 2
Dependent Claim
62 words
A food composition for selectively supplementing essential metals in a mammalian diet and for facilitating absorption of said metals by the mammalian system comprising a food composition containing an effective amount of at least one exogenously synthesized essential metal picolinate complex characterized by the following structural formula: ##STR3## wherein M represents the metallic cation and n is equal to the cation's valence.
Claim 3
Dependent Claim
16 words
The composition as described in claim 1 wherein said essential metal picolinate complex is zinc picolinate.
Claim 4
Dependent Claim
16 words
The composition as described in claim 1 wherein said essential metal picolinate complex is ferrous picolinate.
Claim 5
Independent Claim
59 words
A method for selectively supplementing essential metals in a mammalian diet and for facilitating absorption of said metals by the mammalian system comprising administering to said mammal an effective amount of an exogenously synthesized essential metal picolinate complex characterized by the following structural formula: ##STR4## wherein M represents the metallic cation and n is equal to the cation's valence.
Claim 6
Independent Claim
59 words
A method for selectively supplementing essential metals in a mammalian diet and for facilitating absorption of said metals by the mammalian system comprising administering to said mammal an effective amount of an exogenously synthesized essential metal picolinate complex characterized by the following structural formula: ##STR4## wherein M represents the metallic cation and n is equal to the cation's valence.
