1. A solid dosage form comprising a core coated with a coating;
wherein the core is a tablet comprising a pharmaceutical active, a nutraceutical active, and/or an active dietary supplement, said tablet being itself an immediate-release dosage form;
wherein at least 90 wt % of the coating comprises:
30-70 parts by weight polysaccharide selected from alginic acid, an alginate salt, or any combination thereof;
5-15 parts by weight non-ionic surfactant that is a fatty acid ester of a polyol, which is a glycerol fatty acid ester having an HLB value between 2 and 5; and
20-40 parts by weight wax selected from the group consisting of beeswax, ceresin wax, carnauba wax, and any combination thereof,
wherein the polysaccharide, the non-ionic surfactant, and the wax are mixed together, and
wherein greater than 99 wt % of the coating consists of natural materials wherein the polysaccharide has an average molecular weight between 10,000 and 600,000 g/mol and yields a viscosity of 5-50 centipoise (cps) or 50-100 centipoise (cps), as measured using the ASTM standard for measuring dynamic viscosity, when in a concentration of 1 wt % in water.
