A water soluble nutritional supplement for ruminants is provided that comprises a highly soluble calcium component, a phosphorous component, a potassium component, a copper component, a vitamin C component, and a complete vitamin B complex. The nutritional supplement can be produced in a solid form and be readily dissolved in water. The ingestion of the nutritional supplement in liquid form ensures maximal intestinal absorbability of the vitamins and minerals by the ruminant. The contents of the nutritional supplement are optimized in order to enhance overall ruminant health, antler growth, and milk production.
