Composition for a formulated oral prebiotic edible composition

A formulated oral prebiotic edible composition useful for promoting a desired oral microbiota to treat a respiratory allergic condition and/or an oral and/or sinus infection condition in a subject in need of such treatment, the oral prebiotic comprising:

• a free amino acid containing ingredient comprising L-arginine, the L-arginine comprising free individual molecules of L-arginine, the free individual molecules of L-arginine L present at a concentration of greater than about 0.1 weight percent;
• a carrier, and a sugar comprising at least one of a monosaccharide and disaccharide;
• at least two distinct live lactic acid probiotics, wherein one is a lactic acid producing bacterium, and one is a lactic acid fermenting bacterium;
• wherein the composition is in a configuration suitable to be maintained substantially dissolved within the oral cavity for over a period of at least about 1 minute to about an hour, and wherein the composition is in an effective amount to selectively promote stimulation of a first oral microbiota to produce an excretion product, and wherein a second oral microbiota metabolizes the excretion product to treat the respiratory allergic condition and/or an oral and/or sinus infection condition.
