The present invention relates to a composition comprising a lithium salt of an N-substituted glycine compound and a carrier, wherein the lithium salt of the N-substituted glycine compound is of Formula (I): ##STR00001##
in which R.sup.1, R.sup.2, and R.sup.3 each are independently hydrogen, alkyl, alkenyl, alkynyl, aralkyl, carbocyclyl, aryl, or heteroaryl, or one of R.sup.1, R.sup.2, and R.sup.3 is absent. Also provided in the present invention is a method of mitigating at least one symptom of a neuropsychiatric disorder, comprising administering to a subject in need thereof the lithium salt of an N-substituted glycine compound of Formula (I).

The invention provides cobalamin (vitamin B.sub.12) nutraceutical compositions and methods for use thereof for improving cognitive function in subjects having disorders of cognitive function such as neurodegenerative disorders, neurodevelopmental disorders, and neuropsychiatric disorders. This improvement in cognitive function is achieved through the ability of the cobalamin (vitamin B.sub.12) nutraceutical compositions to increase methylation capacity and vitamin B.sub.12 activity in the brains of the subjects.

The present invention relates to reverse micelle system based on sterols, acylglycerols, phospholipids or sphingolipids and metal ions. Reverse micelle system of the invention is able to cross mucosa and cellular membranes. It thus allows vectorization of metal ions to target sites. It is advantageously useful in the pharmaceutical and dietetic fields.
