Keep your pal healthy with the Zoo Med Repti Calcium with D3 Reptile Supplement. Calcium is essential for the health and wellbeing of reptile and amphibian buddies, and this supplement provides them with a highly bioavailable source of calcium that has no phosphorus or lead. Made with only ultrafine precipitated calcium carbonate, it’s free of impurities and has particles that have a lot of surface area to increase absorption in your pal’s tummy. It also has vitamin D3, known to benefit reptiles that spend most of their time indoors. Using it is easy―simply dust crickets or sprinkle on herbivore food, and then feed your pal as usual. Plus, the formula is made in the USA with no filler or additives.

  • Love the shaker top!

    By on

    This is an essential supplement for most reptiles. Chewy has it at a great price, and I prefer this packaging over others since it's got a shaker top that makes it easy to sprinkle on top of veggies and bugs!

  • Great for Geckos

    By on Top 10 Contributor

    This is a large amount of calcium for a small prize. It's more of a powder than the other brands but it sticks to the insects a lot easier.
