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.

  • My beardie is happy and healthy

    By on

    Calcium d3 is essential for reptile health and this stuff has made my beardie look and feel amazing. I rescued her from a couple that wasn't properly caring for her. Since I've had her and started sprinkling her crickets and her salads with this calcium she's grown a lot and she's a lot more active. Love this stuff!

  • Bearded dragon health

    By on

    I bought this on the advice of a vet to keep my beardie healthy. It was a good price, it arrived quickly and my beardie doesn't seem to notice it on his food. He eats it right up. I like buying from Chewy, I always get great service and have never had a problem.

  • Easy to use

    By on Top 100 Contributor

    I got the calcium with D3 to shake my bearded dragons live food in as to give the bearded dragon the proper calcium intake. This product is easy to use and must not have a bad taste because the bearded dragon gobbles up all the dubia roaches once shaken in the calcium. LOL I do love the shaker top so the product does not all come out at once. This is a great feature. Don't forget to use a multi vitamin as well as the calcium when feeding some reptiles. I would recommend the calcium with D3 and a multi vitamin without D3 as not to overload on calcium. Great product. Must have for reptiles.
