The South Alabama Medical Science Foundation patent solves the following problem:

The folates are ubiquitous to nearly all forms of life. Humans and many other animals lack the capacity to make their own folate which thus is an important vitamin, a kind of important nurient. Anemia especially during pregnancy and geriatric population was an early indication of a dietary requirement for folate. A major function of folate is to remove the unit in a carbon from the molecule metabolized and then deliver them to the molecules synthesized. As an example, folate participates in the building of nucleic acid. Furthermore, the activity of DNA controlled, in part, by methylation, and the primary methylating agent in the body (S-adenosylmethionine) made a metabolic cycle involving a folate. Many studies, therefore, focus on the relationship of folate status to cancer susceptibility, especially colorectal adenoma.

Our analysis of this patent is as follows:

South Alabama Medical Science Foundation’s patent US 6254904 B1 deals with Food and vitamin preparation containing the natural isomer of reduced folates.
A composition for human or animal consumption for providing folate include a natural isomer of reduced folate, such as (6S) -tetrahydrofolic acid, 5-methyl- (6S) -tetrahydrofolic acid, 5-formyl – (6S) -tetrahydrofolic acid, 10-formyl- (6R) -tetrahydrofolic acid, 5,10-methylene- (6R) -tetrahydrofolic acid, 5,10-methenyl- (6R) -tetrahydrofolic acid, 5-formimino- ( 6S) -tetrahydrofolic acid, and their polyglutamyl derivatives disclosed. The composition included in multivitamin preparations (or without minerals and other nutrients); breakfast foods such as prepared cereals, toaster pastries and breakfast bars; baby formula; Dietary supplements and whole foods and weight-loss formulas and bars; animal feed (for example to pet food) and animal feed supplements (like chicken feed). The amount of natural isomer of a reduced folate in a composition for human consumption include between about 5% and 200% of the daily requirement for folic acid per serving or the dosage.
