Abstract: A nutritional supplement for a human, the supplement having a chelate comprised of an N-acetyl-L-cysteine ligand bonded to a metal to form a chelate ring. A method for preparing a chelate comprised of N-acetyl-L-cysteine ligand and a metal having the steps of: dissolving an amount of N-acetyl-L-cysteine in an aqueous solution, adding a metal to the aqueous solution, stifling and heating the aqueous solution, and removing the solvent under reduced pressure. A method of treating a human for one or more of oxidative stress, cardiovascular disease, cerebrovascular disease, neurodegenerative diseases, Alzheimer's disease, ADHD, bipolar, schizophrenia, autism, dementia, and HIV in a human comprising administering an effective amount of a composition having N-acetyl-L-cysteine in a chelate formation with a metal. A compound having a chelate formulation with a metal being chelated by an N-acetyl-L-cysteine ligand.

Abstract: A multiple folate composition having at least 3 different forms of folate comprising at least one of folic acid (a salt or ester thereof); at least one of a folinic acid (a salt or ester thereof); and at least one of a 5-methyl-tetrahydrofolic acid (a salt or ester thereof) is disclosed. The composition is useful as a nutritional supplement or medication in the treatment of folate deficiency and the sequella thereof and/or in conditions responsive to administration of metabolically useful folate. The compositions are particularly of use in patients who have impaired or reduced ability to convert folic acid to its metabolically active forms, and in the treatment of depression.
