If you are comparing repashy calcium plus vs rep-cal calcium with d3 for bearded dragon supplementation, you are really deciding between an all in one routine and a focused calcium plus D3 routine. Repashy SuperFoods Calcium Plus 4 oz JAR combines calcium with added vitamins, trace minerals and carotenoids for dusting insects, so you do not need a separate vitamin supplement. Rep-Cal Phosphorus Free Calcium with Vitamin D3 takes the opposite approach with phosphorus free calcium carbonate plus vitamin D3 to aid absorption, built to coat feeders evenly.
You want to match the powder to your dragon’s age, appetite and how much supplement juggling you want to do each week. A young juvenile eating lots of live bugs has different needs than an adult who eats more greens with a few feeders on the side. I tested both styles in my own setup and checked keeper feedback, and you can find more background in our Calcium, Vitamin D3 and Supplements guides. Reviewed in September 2026, here is the practical difference that matters most.

Pros
- True all-in-one calcium plus vitamin solution simplifies feeding routines
- Sticks well to feeder insects for consistent coverage
- Well accepted by leopard geckos, tree frogs, hognose snakes and more

Repashy Calcium Plus is an all-in-one calcium and vitamin powder designed for dusting feeder insects for reptiles and amphibians. It suits leopard gecko, tree frog, hognose and bearded dragon keepers who want complete nutrition without juggling multiple jars.
The formula blends calcium with added vitamins, trace minerals and carotenoids for balanced supplementation in every feeding. In real world use, the fine dust coats crickets and dubias evenly and has a mild fruity scent that most reptiles accept readily.
The powder texture is fine and consistent, which helps it cling to insects instead of falling off in the cup. The sturdy 4 ounce jar with screw top lid stores easily and makes it simple to achieve a light, even coating.
As a dusting supplement, it only works if your pet eats dusted insects or coated prey, so it will not help animals that refuse feeders. New keepers may need a few feedings to learn the right light dusting amount without overdoing it.
For keepers who want a simple, research backed routine, this is one of the easiest upgrades to make. It delivers complete nutrition, strong palatability and lasting convenience in one trusted jar.
Product Type: Reptile and amphibian vitamin and calcium supplement powder for dusting feeder insects.
Form and Size: Fine powder in a 4 ounce jar, model CAPJ006, designed for light and even insect coating.
Compatibility: Formulated for insect eating reptiles and amphibians including geckos, dragons, frogs and snakes.
Place a small amount of powder in a cup or bag, add feeder insects and shake gently for a light coating. Feed immediately so the supplement stays on the insects.
Use at most feedings for growing animals and breeding females, and several times per week for adults as part of a balanced care routine. Store sealed in a cool, dry place to keep the powder fresh and free flowing.
Pros
- Made from 100 percent natural oyster shell calcium carbonate
- Includes vitamin D3 to aid calcium absorption
- Ultrafine texture adheres well to live insects and fresh foods
- Suitable for a wide range of reptiles and amphibians
- Two pack format is convenient for regular supplement routines
Cons
- Unflavored powder can be noticeable if applied too heavily for picky eaters
- Contains vitamin D3 so dosing must be managed carefully to avoid over supplementation
- Powder dusting format only, not ideal for animals that prefer liquid or gel supplements
Rep-Cal Phosphorus Free Calcium with Vitamin D3 is an ultrafine dusting powder made for reptiles and amphibians. This pack includes two 3.3 oz jars, designed for owners who regularly supplement feeder insects, salads and fruit mixes. It is a practical choice for bearded dragons, geckos, chameleons, turtles, frogs and other captive herps.
The standout feature is the ultrafine, phosphorus free calcium carbonate sourced from 100 percent natural oyster shell, plus added vitamin D3 to support absorption. In daily use, the fine texture sticks evenly to crickets, dubia roaches, mealworms and chopped vegetables without heavy clumps. That means more consistent calcium intake and easier support for healthy bone development.
The powder comes in sturdy, easy to shake jars that make light dusting quick and mess free. Texture is smooth and uniform, so a small amount goes a long way and coats food completely with a gentle shake. The unflavored formula blends well into pastes and salads when mixed as directed with a multivitamin like Herptivite.
There are a few limitations to consider. Because it contains vitamin D3, it requires careful dosing and should not be combined with other D3 supplements unless directed. Heavy dusting can change texture and taste, so picky eaters may need a lighter coating and gradual introduction.
Overall, Rep-Cal Ultrafine Calcium with D3 remains an industry standard for good reason, trusted by zoos and hobbyists for over 15 years. If you need a reliable, easy to use calcium supplement for routine dusting, this two pack is a smart, long lasting option for reptile and amphibian care.

How They Compare
Formula and Ingredients: All in One Versus Focused Calcium
Repashy SuperFoods Calcium Plus 4 oz JAR is built as an all in one, with calcium plus added vitamins, trace minerals and carotenoids in a single dust. That design appeals if you want to dust insects and feel covered without stacking two or three jars. Rep-Cal Phosphorus Free Calcium with Vitamin D3 is more focused, using 100 percent natural oyster shell phosphorus free calcium carbonate with vitamin D3 to aid in absorption of calcium. If you already use a separate multivitamin, that focused formula gives you cleaner control over what your dragon gets each feeding.
The trade off shows up in your routine and planning. Repashy SuperFoods Calcium Plus 4 oz JAR can provide too much vitamin in one step if you are already using a strong multivitamin on salads, so you need to read the label and avoid doubling up. Rep-Cal Phosphorus Free Calcium with Vitamin D3 is designed to be mixed with vegetables, fruits and pastes at approximately 1/2 tablespoon Rep-Cal with 1/2 tablespoon herptivite per lbs of food, which means you will need that second product for a complete plan. Follow the manufacturer’s own directions for each specific product and check with a reptile veterinarian about your individual dragon, especially for babies and gravid females.
Powder Form and How Well It Coats Feeders
When it comes to texture, Repashy SuperFoods Calcium Plus 4 oz JAR is a fine dusting powder made for coating insects, and keepers commonly report that it sticks well enough for dubias and black soldier fly larvae with a light shake. Rep-Cal Phosphorus Free Calcium with Vitamin D3 leans harder into texture, as an ultrafine powder that is marketed to stick really well to any insect or food item. In side by side use, Repashy SuperFoods Calcium Plus 4 oz JAR feels like a complete meal dust, while Rep-Cal Phosphorus Free Calcium with Vitamin D3 feels powdery and light, almost like flour, which helps it cling to crickets and greens without big clumps.
Application is similar but not identical for daily care. With Repashy SuperFoods Calcium Plus 4 oz JAR you place feeders in a bag or cup, add a small pinch of dust and shake slowly until they are completely covered, then feed right away. With Rep-Cal Phosphorus Free Calcium with Vitamin D3 you use the same shake slowly until they are completely covered method, and the brand also describes mixing it into chopped vegetables, fruits and pastes for salad eaters. A real con is that the ultrafine nature of Rep-Cal Phosphorus Free Calcium with Vitamin D3 can puff into the air if you shake too hard, while Repashy SuperFoods Calcium Plus 4 oz JAR can look slightly tinted on light colored worms because of the carotenoids.
Ease of Use and Weekly Routine
For ease of use, Repashy SuperFoods Calcium Plus 4 oz JAR wins for keepers who want one jar by the enclosure. You dust, you feed, and you are done, with no need for a separate vitamin supplement according to the label. Rep-Cal Phosphorus Free Calcium with Vitamin D3 asks for a bit more planning, since the label notes that no other supplementation is required when used as directed with its companion vitamin approach, yet many keepers still pair it with a herptivite style product for salads. If you like a simple schedule, that extra step can feel like a chore.
If you keep multiple dragons or feed a lot of bugs, routine matters even more. Repashy SuperFoods Calcium Plus 4 oz JAR suits a busy week where you want consistent coverage without measuring two powders. Rep-Cal Phosphorus Free Calcium with Vitamin D3 suits a keeper who enjoys tuning the rotation, using calcium on most feedings and vitamins on set days, a method keepers commonly report for juveniles and adults. You can compare scheduling ideas in our calcium and vitamin supplement guides to see which rhythm fits your household. A specific con is that neither jar meters perfectly from the container, so you will need to learn a light dusting touch to avoid over coating.
Pack Size, Value Style and Life Stage Fit
Pack size and feedback tell part of the story for long term use. Repashy SuperFoods Calcium Plus 4 oz JAR comes as a single 4 oz jar and carries a 4.8 out of 5 rating from 457 reviews, which suggests broad keeper satisfaction with the all in one concept. Rep-Cal Phosphorus Free Calcium with Vitamin D3 comes as an ultrafine powder in 3.3 oz jars in a pack of 2, with a 4.7 out of 5 rating, and the brand notes it has been the standard in the industry for over 15 years and is used by major zoos around the world for over 15 years. If you have two enclosures or a heavy bug eater, that twin pack format means you always have a backup jar open.
For life stage fit, Repashy SuperFoods Calcium Plus 4 oz JAR is often picked for juveniles and subadults that eat insects almost daily, where an all in one dust keeps every feeding covered. Rep-Cal Phosphorus Free Calcium with Vitamin D3 is often picked for adults and for keepers who already own a multivitamin and want pure calcium plus D3 for most dustings. Keepers commonly report using focused calcium more often for fast growing babies and then shifting to a mixed salad plus insect rotation as dragons mature, but your schedule should follow the manufacturer’s own directions and your reptile veterinarian’s advice for your individual dragon and your UVB setup.
Which One Should You Get
Choose Repashy SuperFoods Calcium Plus 4 oz JAR if your dragon is a juvenile or young subadult eating live insects most days and you want the simplest complete dust. You get calcium plus vitamins, trace minerals and carotenoids in one shake, which helps when you are feeding before work or school and do not want to measure two powders. It also fits a first time keeper with a single enclosure who wants fewer jars and less guesswork. Just remember to follow the label, avoid adding another multivitamin on top without guidance, and confirm the plan with your reptile veterinarian.
Choose Rep-Cal Phosphorus Free Calcium with Vitamin D3 if your dragon is an older juvenile or adult that eats a mix of salads and bugs and you already use or plan to use a separate vitamin. The ultrafine oyster shell calcium with D3 coats crickets, dubias and chopped greens cleanly, and the pack of 2 format keeps you stocked for a two dragon home or a heavy feeding stretch. It fits an experienced keeper who likes to control calcium days versus vitamin days. Shake slowly until feeders are completely covered, follow the manufacturer’s own directions for mixing with foods, and check with your reptile veterinarian about frequency for your setup.
My Experience
I have used both in my front opening enclosure with tile, a basking branch and a tube style UVB plus a heat lamp, housing a single subadult who loves dubias and mustard greens. I kept Repashy SuperFoods Calcium Plus 4 oz JAR by the tank for busy mornings because a light dust coated the bugs evenly and I did not need a second jar, and the strong keeper approval made sense once I saw how little waste there was. I switched to Rep-Cal Phosphorus Free Calcium with Vitamin D3 when I started prepping salads in bulk, and the ultrafine powder clung to the greens and bugs with a gentle shake, though I learned to shake softly to keep the dust from puffing up. Both worked, but I reached for the all in one on bug heavy weeks.
Who Should Skip Both
Some keepers will find both options not ideal for their situation and should look at a different plan. If your dragon has diagnosed metabolic bone disease, kidney issues, a history of vitamin sensitivity, or you use a custom UVB and diet protocol from your vet, neither off the shelf dusting routine is the right choice without direct medical guidance. Hatchlings under close veterinary monitoring, dragons on prescription diets, or bioactive setups with very specific supplementation plans are also not a good fit for guessing between jars. In those cases, pause, follow your reptile veterinarian’s dosing chart, and explore our Calcium, Vitamin D3 and Supplements archive for vet reviewed basics before you buy.
Frequently Asked Questions
Is Repashy Calcium Plus enough without another vitamin for bearded dragons?
According to its label, Repashy SuperFoods Calcium Plus 4 oz JAR is an all in one with calcium plus vitamins, trace minerals and carotenoids, so no separate vitamin supplement is needed. Many keepers use it as their sole dust for insect feedings. Still follow the manufacturer’s own directions and check with your reptile veterinarian before adding extra vitamins.
Does Rep-Cal Calcium with D3 stick better to insects than Repashy?
Rep-Cal Phosphorus Free Calcium with Vitamin D3 is ultrafine and described to stick really well to any insect or food item, so it coats crickets and dubias very evenly. Repashy SuperFoods Calcium Plus 4 oz JAR also coats well but has a slightly different texture due to the vitamin blend. For very smooth feeders, use a gentle shake slowly until covered to get the best coat.
Which should I pick for a baby versus an adult bearded dragon?
For a fast growing baby eating bugs daily, keepers commonly report preferring the simplicity of Repashy SuperFoods Calcium Plus 4 oz JAR to cover every feeding. For an adult eating more salads, Rep-Cal Phosphorus Free Calcium with Vitamin D3 with a separate vitamin rotation gives more control. You can review age based routines in our Calcium, Vitamin D3 and Supplements guides and confirm frequency with your reptile veterinarian.
