A method for preparing a super absorbent polymer and a superabsorbent polymer prepared from the same are disclosed herein. In some embodiments, a method includes mixing super absorbent polymer particles, water and an additive form a hydrated super absorbent polymer, wherein the super absorbent polymer particles comprise a base polymer powder including a cross-linked polymer polymerized from a water-soluble ethylenically unsaturated monomer having an acidic group of which at least a part is neutralized, and a surface cross-linked layer formed on the base polymer powder, wherein the surface cross-linked layer is formed by further cross-linking the cross-linked polymer, and wherein the additive including a polyoxyalkylene aliphatic hydrocarbon ether carboxylic acid. The method can appropriately control the water content of the super absorbent polymer by water-addition or the like to suppress crushing or the like during transfer, and also can suppress deterioration of physical properties.
