A palatable source of high quality cholecalciferol, the precursor to Vitamin D3 for dogs and cats. Blended with virgin olive oil and diluted sufficiently to enable safe usage in animals as small as 4 kg.
 
Recent research studies in dogs, cats and humans have found Vitamin D3 insufficiency highly correlated with a number of difficult-to-treat chronic diseases such as cancer, heart disease, inflammatory bowel disease, renal disease, hyperparathyroidism, and feline tooth resorption. By wellness-checking regularly for serum levels of Vitamin D3, those patients with insufficient levels of Vitamin D3 can be identified and supplemented accurately with RxD3.  A monthly follow-up test is recommended to insure safe and adequate dosing, and testing thereafter as recommended by your veterinarian.
