The invention relates to a vitamin water aqua. The raw materials of the water aqua comprise liposome, vitamin A, vitamin D, vitamin E, vitamin K, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, vitamin H, folic acid and solubilizer. In the invention, liposoluble vitamins are coated in a microcapsule structure of the liposome and form a homogenized and stable water aqua with water-soluble vitamins. The water aqua has stable storage character in a long time, smaller grain diameter of components and a cytoid structure and can activate the self immunologic function after entering an animal body to keep the immune level of organisms in a higher state; and meanwhile, a plurality of vitamins can be effectively stored in the organism, so that the invention avoids the problems of the loss and the insufficient utilization rate of the vitamins in the metabolic process, remarkably improves the utilization rate and the conversion rate of feed, improves the antibody level of animal organisms and enhances the disease resistant capability.
