Vetark Arkvits is a high-potency, multivitamin and trace element mixture, particularly useful in the diet of large or more adult reptiles. Arkvits are a blend of Vetark Nutrobal and Vetark ACE-High supplements in a 2:1 ratio. This ensures a great mix of essential vitamins and calcium to ensure ultimate reptile and amphibian health. Its high strength means that a smaller amount is needed in comparison to more general-purpose multivitamins. The high calcium/phosphorus ratio in Arkvits helps to stave off metabolic bone disease (MBD), a common disease in reptiles, and to also promote healthy growth of bones and shells.
