A one-time dose of Vitamin D of 800IU + should not really be a problem as the normal daily dose is 227 IU/lb of food consumed on a dry matter basis and a toxic dose gtiven over months would be 2272 IU /lb food consumed on a dry matter basis. So even a high one-time dose of Vitamin D plus Calcium should not cause any toxic signs or damage.
