Description
Keep calcium flowing into your reptile or amphibian’s diet with a bigger supply on the shelf. Zoo Med Repti Calcium without Vitamin D3 is an ultra-fine precipitated calcium carbonate supplement, and this is the larger 12-ounce size for owners who dust often or care for more than one animal. It’s the without-D3 formula, so you decide how and when to add D3 separately while still giving your pet the phosphorus-free calcium it needs. The roomy size is a natural fit for busy keepers and multi-pet households that go through supplement quickly. Keeping D3 separate also lets you tailor each animal’s routine to its own needs, which is a big reason seasoned keepers favor the without-D3 formula in this larger, longer-lasting amount.
Why the 12-ounce Repti Calcium without D3 earns a spot in your routine:
An ultra-fine powder that dusts smoothly and evenly over feeders and fresh greens at mealtime.
Phosphorus-free calcium, made specifically for reptiles and amphibians rather than general pets.
Contains no added Vitamin D3, leaving D3 supplementation fully in your hands and on your schedule.
Zoo Med points to the unique shape and high surface area per gram, which the brand says results in increased calcium bioavailability.
Described by the brand as a highly bioavailable source of calcium carbonate, formulated to be readily usable by your pet.
Free of harmful impurities, and specifically not derived from oyster shells.
The generous 12-ounce size means fewer refills, handy for frequent feeders or multi-pet homes.
Intended for additional supplementation, so it slots right into your established feeding plan.
Proudly Made in the USA, for owners who value knowing where their pet’s supplements come from.
A practical, larger-volume way to keep calcium a steady part of your herp’s diet.
If you find yourself reaching for calcium often, the 12-ounce Repti Calcium without D3 keeps you well stocked without constant restocking and saves a few trips to the shelf. Dust it on at feeding time, support your pet’s routine, and trust a supplement made to deliver calcium the way you want to give it. For high-volume keepers, the larger bottle simply means more time between trips to restock.
