All in One Supplement vs Separate Calcium and Multivitamin
One tub used at every feed, or two tubs on a rota. Which is harder to get wrong, and what to check on the label either way.
The short version
An all in one supplement is harder to get wrong, because there is one powder, one schedule and no chance of accidentally doubling up on vitamin D3 or vitamin A. That simplicity is worth a lot, since supplement errors in this hobby are usually errors of arithmetic rather than intent. Separate calcium and multivitamin gives you finer control, which matters if a vet has asked you to adjust one without the other, or if your lighting situation makes the D3 question specific. Whichever you choose, use one system consistently and read every label for D3 and preformed vitamin A.

Choose the Repashy Calcium Plus if…
Choose an all in one if you want a routine you cannot muddle: the same powder, the same light dusting, at the frequency the manufacturer specifies for your animal's age. It suits households where more than one person feeds the dragon. Check which version you are buying, since several brands sell both a standard and a low D3 variant intended for animals under strong UVB, and those are not interchangeable.

Choose the Zoo Med Reptivite without D3 if…
Choose separate products if you want to vary calcium and vitamins independently, if your vet has given you specific instructions, or if your UVB situation means you want plain calcium most of the time with a multivitamin only occasionally. Write the schedule on a card taped to the enclosure. The most common failure with a two tub system is losing track of which was last used, which then shows up either as a deficiency or as over supplementation.

A T5 10.0 UVB Fixture, the One Thing You Cannot Skip
Metabolic bone disease is the most common preventable illness in captive bearded dragons, and it comes down to inadequate UVB. A linear T5 tube across the basking side does what a coil bulb cannot, and the tube needs replacing roughly annually even when it still lights up.
Frequently Asked Questions
Can I use a supplement made for another reptile?
Sometimes, but check the requirements rather than assuming. Species differ substantially in D3 and vitamin A needs, and a product formulated for an animal kept without UVB will contain more D3 than a desert species under a strong lamp needs. If you keep several species, that is a good reason to prefer products that state which group they are intended for.
Does dusting powder actually stay on the insect?
Not for long, which is why insects are dusted immediately before feeding rather than in advance. Roaches and worms groom powder off within minutes. Feeding in a smooth sided dish rather than loose in the enclosure keeps more of the powder with the insect and keeps the insect off the substrate. It also lets you see how much was actually eaten.
My dragon has stopped eating. Is that a supplement problem?
Treat it as a health question first. Appetite loss in a bearded dragon can follow a temperature or lighting problem, but it also accompanies parasites, infection, impaction, mouth disease, gravidity in females and the seasonal slowdown of brumation, which can be difficult to tell apart from illness. A dragon that is not eating and is also losing weight, lethargic or hiding needs a reptile vet, and a faecal test is often the first useful step.
