Claim Text:
1. A tablet product, comprising: a tablet matrix; beadlets within the tablet matrix, the beadlets being intact within the tablet matrix, the beadlets comprise an inert generally spherical core and a coating comprising a stabilizing antioxidant, a lipophilic nutrient, and a binding agent, the lipophilic nutrient comprises one or more carotenoids selected from at least one from the group consisting of lutein, lutein esters, alpha-carotene, beta-carotene, zeaxanthin, zeaxanthin esters, astaxanthin, lycopene, and mixtures thereof, the beadlets contain 1 to 50 wt % of lipophilic nutrient, the coating being applied on the inert generally spherical core as a colloidal suspension that is formed by a solution of the stabilizing antioxidant and the lipophilic nutrient that is first dispersed in a non-polar solvent, and then with addition of a polar solvent, wherein a ratio of non-polar solvent to polar solvent ranges from about 0.1:1 to about 2:1, the colloidal suspension is mixed with the binding agent, an amount of the binding agent ranges from about 0.1% to about 10% of the weight of the beadlets, the coating being applied by a bottom-spray fluidizing-bed system, the beadlets having the coating uniformly coated on the generally spherical inert core, the beadlets having an angle of repose between about 22 degrees to about 27 degrees, and the beadlets and the tablet matrix together form the tablet product having a hardness of about 10 kg/cm
