Verdict
Keepers who mention Calcium Plus tend to treat it as a default all-in-one staple rather than something to argue about, so it is clearly trusted, but concrete owner verdicts on it are thinner than its popularity suggests. The pattern that recurs is about dosing rather than whether it works: keepers running it without UVB do not dust every feeding, they use the full-D3 all-in-one a few times a week and alternate with a plain no-D3 calcium the rest of the time, which keeps D3 in a sensible band. That schedule is the community's practical answer to the standard version's full D3, and it fits the wider hobby caution that D3 is the one supplement where more is not better once UVB is in the picture. The routing to the low-D3 LoD version for UVB setups, and the caution that a shared calcium-and-vitamin jar lets the vitamins degrade over the long life of a big tub, are well-established keeper concerns rather than points these particular threads resolve.

Repashy Calcium Plus is the supplement a lot of keepers reach for when they want one jar to do everything. It is an all-in-one calcium and multivitamin powder with D3 built in, so instead of juggling a separate calcium pot, a separate vitamin pot, and a separate D3 source, you dust with a single fine powder and move on. For a first-time keeper standing in front of a wall of supplement tubs, that simplicity is the whole appeal, and it is a genuinely well-regarded formula that has been a staple in the hobby for years.
The catch is baked into the name of its sibling. This is the standard Calcium Plus, which carries a full dose of D3, and D3 is the one supplement where more is not better. A reptile sitting under strong UVB is already making its own D3, and if you then dust every feeding with a full-D3 powder, you can stack the two and push toward oversupplementation over time. That is not a reason to avoid it, it is a reason to match the version to your lighting, which is exactly why Repashy also sells a low-D3 version called Calcium Plus LoD.
So the honest read is positive with a caveat you have to get right. As an all-in-one for a keeper who is not running heavy UVB, or who doses it a few times a week rather than every single feeding, Calcium Plus is a smart, convenient, and economical choice. As a dust-every-feeding staple under a strong UVB lamp, the standard full-D3 version is the wrong tool, and the low-D3 version or a plain-calcium-plus-separate-vitamins approach is safer. Which camp you are in decides whether this exact jar is right for you.
The short version
What's good:
- All-in-one: calcium, a multivitamin, and D3 in one fine powder, so one jar covers what usually takes three.
- A long-trusted formula with a loyal following across geckos, dragons, and other insectivores.
- The powder is fine and light, so it clings to feeders evenly without clumping or shedding.
- A 6oz jar dusted lightly lasts a very long time, which makes the cost per feeding tiny.
What's not:
- The standard version carries full D3, which can oversupply a reptile that is also making D3 under good UVB.
- Because calcium and vitamins share one jar, the vitamin fraction can degrade over the months it takes to finish a big tub.
- All-in-one means you cannot dial calcium and vitamins independently the way separate pots let you.
- Not the right pick if your care sheet calls for plain calcium without D3 at most feedings.
Which reptiles and setups it fits
Buy it for:
- A no-UVB or low-UVB insectivore, like a leopard gecko kept without a UVB lamp, where a dietary D3 source is genuinely needed and full-D3 makes sense in moderation.
- A keeper who wants one simple staple and is happy to dose it a few times a week rather than every feeding, which is how most experienced owners actually run it.
- Anyone tired of juggling three separate tubs who wants a single reliable all-in-one to simplify feeding night.
Pick something else if:
- Your animal lives under strong UVB and you dust every feeding, where stacking full dietary D3 on top of UVB-made D3 is the real risk. The low-D3 Calcium Plus LoD is built for exactly this.
- Your care sheet calls for plain calcium without D3 at most feedings, in which case a separate no-D3 calcium tub like Zoo Med Repti Calcium is the correct base.
- You want to control calcium and vitamin dosing independently, which an all-in-one by design will not let you do.
The specs that matter
This is a powder, so the things that matter are what is in it and how you use it, not build quality in the usual sense.
- All-in-one with D3. Calcium, a full multivitamin, and vitamin D3 are combined in one powder, which is the entire selling point and the entire caveat. It means one jar does the job of three, and it means you are adding D3 every time you dust.
- This is the standard, full-D3 version. It is easy to grab the wrong jar. The standard Calcium Plus carries full D3; the LoD version carries much less for UVB setups; and Repashy SuperCal NoD, MeD, and HyD are plain calciums at different D3 levels. Confirm you are holding the all-in-one standard Calcium Plus, not a sibling, before you build a schedule around it.
- Fine, light powder. It dusts feeders evenly and clings well, which matters more than it sounds: a powder that clumps or sheds means your animal gets an uneven dose. This one is consistently praised for its texture.
How it keeps your animal safe
For a supplement, safety is not about a probe or a cutoff, it is about dose, and the one number that can hurt an animal here is D3. Vitamin D3 drives calcium absorption, and a reptile needs it, but D3 is fat-soluble, which means excess is stored rather than flushed, and chronic oversupply can lead to hypervitaminosis D and soft-tissue calcification. This is the axis where the standard Calcium Plus earns its main caveat.
The mechanism is simple. A reptile under a good UVB lamp synthesizes its own D3 from the light. If you then dust every feeding with a full-D3 powder, you are adding a second D3 source on top of what the lamp already provides, and over months that can stack higher than the animal needs. That is not a knock on the formula, it is a mismatch between a full-D3 product and a full-UVB setup. Repashy sells the low-D3 LoD version precisely so UVB keepers get the all-in-one convenience without the D3 stacking, and pointing UVB setups to LoD is the single most important routing decision in this review.
For the other big group of keepers, the no-UVB and low-UVB crowd, the calculus flips. A leopard gecko kept without UVB genuinely needs dietary D3 to use its calcium, and here full-D3 Calcium Plus is doing a necessary job. Even then, the community pattern is not to dust it at every single feeding but to use it a few times a week and alternate with a plain calcium that has no D3, which keeps the D3 in a sensible band. Get the version and the frequency right for your lighting and this is a safe, effective supplement. Get them wrong and the exact same jar becomes a slow overdose, which is why the version on the label matters as much as the brand.
Build quality and living with it
For a powder, build quality means formulation quality, consistency, and how it holds up in the jar, and on the first two Calcium Plus is strong. The formula is well regarded, the powder is fine and even, and it dusts feeders cleanly without the clumping that plagues cheaper supplements. A 6oz jar goes a remarkably long way when you are dusting lightly, so the cost per feeding is small and a single jar can last many months.
That longevity is also where the one real living-with-it caveat comes from, and it is a caveat the community raises rather than the marketing. When calcium and vitamins share a single jar, the vitamin fraction can slowly degrade over the long stretch it takes to use up a big tub, especially once the seal is broken and it is exposed to air and humidity feeding after feeding. Fat-soluble vitamins are not infinitely stable, and an all-in-one that lasts a year is an all-in-one whose vitamins have been sitting mixed with calcium for a year. Keepers who care about this either buy a smaller jar they will finish faster, store it sealed and cool, or step up to separate calcium and multivitamin pots so each stays fresh on its own schedule. None of that makes the product bad, it is the inherent tradeoff of the all-in-one convenience, and it is worth knowing before you buy the biggest jar on the shelf.
How it compares
- Versus Calcium Plus LoD: the same all-in-one formula with much less D3, and the better choice the moment strong UVB enters the picture. If your animal is under a quality UVB lamp, LoD gives you the one-jar convenience without stacking D3. The standard version reviewed here is for no-UVB or low-UVB setups, or for dosing a few times a week.
- Versus a plain no-D3 calcium like Zoo Med Repti Calcium: a different philosophy. A separate no-D3 calcium lets you dust at every feeding with zero D3 risk, then add D3 and vitamins separately on your own schedule. It is more jars and more thinking, but it gives you full control and is the safest base for a UVB animal that only needs occasional supplemental D3.
- Versus a beta-carotene multivitamin like Arcadia EarthPro-A: not a rival, a balancer. EarthPro-A supplies vitamin A as beta-carotene, which the body converts only as needed rather than storing, sidestepping the vitamin A overdose worry that dogged older supplements. Some keepers run it alongside a plain calcium base instead of relying on a single all-in-one for everything.
Setting it up
Match the version to your lighting first, because that decision outranks everything else. Strong UVB means the low-D3 LoD version; no or low UVB means the standard full-D3 jar reviewed here.
Then set a frequency instead of dusting blindly at every feeding. The common experienced-keeper pattern for a no-UVB insectivore is to use the full-D3 all-in-one a few times a week and alternate with a plain calcium that has no D3 the rest of the time, which keeps D3 in a safe band while still covering calcium at every meal. Dust lightly, coat the feeder just enough to see it, and store the jar sealed and cool so the vitamin fraction stays fresh. If you keep multiple species, remember a care sheet written for a UVB animal and one written for a no-UVB animal will not call for the same jar. The wider logic of calcium, D3, and UVB is covered in our reptile calcium supplement guide.
The bottom line
Repashy Calcium Plus is a genuinely good all-in-one, and for the right setup it is one of the simplest, most economical ways to cover calcium, vitamins, and D3 in a single step. Keepers have trusted the formula for years, the powder is excellent, and a jar lasts a long time.
Just buy the version that matches your lighting. The standard full-D3 jar reviewed here is right for no-UVB and low-UVB animals and for anyone dosing a few times a week, but under strong UVB the full D3 can stack toward oversupply, and that is what the LoD version exists to solve. Respect the D3, dose on a schedule rather than every feeding, and keep the jar fresh, and this is a smart, honest staple. Ignore the version on the label and it is the right formula aimed at the wrong animal.
Our Ratings
Overall score
For a powder, build quality is formulation and consistency, and here it is strong. The formula is well regarded and long-trusted, the powder is fine and light so it clings to feeders evenly without clumping, and a 6oz jar dusted lightly lasts many months. The one built-in tradeoff is that combining calcium and vitamins in a single jar lets the vitamin fraction degrade over the long life of a big tub, which is why some keepers buy smaller or split into separate pots.
The axis that carries the main caveat. This is the standard, full-D3 version, and D3 is the one supplement where excess is stored rather than flushed. Under strong UVB, dusting every feeding with full dietary D3 stacks on top of the D3 the lamp makes and can push toward oversupply over time, which is exactly why the low-D3 LoD version exists. For no-UVB and low-UVB animals dosed a few times a week alongside a plain no-D3 calcium, it is safe and doing a necessary job. Match the version and frequency to your lighting and the risk goes away.
Its quiet strength. A 6oz jar of a fine, light powder goes a long way when you dust lightly, so the cost per feeding is tiny and one jar can cover many months, and the all-in-one design replaces what would otherwise be three separate tubs. The value only holds if you buy the version that matches your lighting and finish the jar before the vitamins age, so match it right and it is an economical staple rather than a jar you throw out half-used.

What Reddit Is Saying
“That's a really good multivitamin. So sounds like you're doing a good job with powders.”View thread →
“Repashy calcium plus is great because it has preformed vitamin A. This is essential. Without it they can have skin and eye issues.”View thread →
“Calcium Plus is a potent multivitamin with a significant amount of d3 and calcium. You don't need to be dusting with both. Just use the Repashy Plus.”View thread →
“I tend to recommend using this produce once a week, and calcium for all other feedings. It's great stuff. Though you've bought a monstrous amount, you'll be tossing this container in the trash in a year since vitamins should be replaced at least yearly, every 6 months for older geckos. Keep your vitamin in the fridge to keep it fresh longer.”View thread →
“That's your multivitamin to use every 4th feeding, you should also get calcium without d3 to use for the other feedings. If you don't have a linear UVB also get calcium with d3 to put in that rotation (this wouldn't hurt even if you have a UVB).”View thread →
“Secondly, in the community in my country, they say these are just vitamins, not calcium, and can't be given regularly, need a separate bottle of calcium with D3 for regular feeding.”View thread →
“Okay thank you! I'll see what i can find without d3, just checked and there is also d3 in her paste. that must be a lot”View thread →
“Ok, monitor it to see if it gets worse. Also you should change up what's your dusting with, too much D3 can cause kidney failure! That's why if you use UVB you always want to use a calcium that doesn't have d3 in it.”View thread →
