Top 8 Best Bearded Dragon Calcium Powders (with and without D3)

Bringing a bearded dragon home as a pet is more or less the same as adopting a child. You need to satisfy each of its needs to ensure the health and safety of this reptile. Since they are on their own for taking care of themselves in the wild, and with plenty of resources, bearded dragons can survive good and well. However, in captivity, the resources are limited, making you responsible for each of their needs.

Bearded dragons need a good supply of nutrients to maintain their health, and one of the essential nutrients they need is calcium. Calcium must be provided through calcium-rich food items; however, sometimes, your beardie may get reluctant to eat a particular food, which may cause a deficiency of calcium in their body. In this case, the bearded dragon must be given additional calcium supplements.

When you look for calcium supplements, you may come across multiple options that may confuse you. Here, we’ll provide you with a list of the best calcium supplements and the importance of this nutrient for the beardie in detail.

Best Calcium for Bearded Dragons with D3

The calcium powder that you’re using for your bearded dragon may or may not have vitamin D3. Vitamin D3, as mentioned earlier, is essential for a bearded dragon to absorb calcium in its body. However, the required vitamin D3 is obtained from the UVB light, and hence its presence in the supplement is mainly not needed.

The calcium supplement comes at times with vitamin D3, which raises the question of whether or not you should provide calcium supplements with vitamin D3. Below is a quick review of how and when you should use D3 in supplements.

1. Rep-cal Calcium With Vitamin D3

Rep-cal is the most popular calcium supplement for your bearded dragon. It has been recommended by many bearded dragon owners and breeders. It is a finely ground calcium supplement that is easy to use and almost seamless for your bearded dragon.

Whenever you’re looking for a calcium supplement, the first thing that you want to look at is whether the supplement is phosphorus-free or not. Rep-Calc is a supplement made naturally by oysters and is entirely free of phosphorus, with no sugar, or starch additives.

2. Repashy Calcium Plus with Vitamin D3

So, although Repashy calcium plus is a great recommendation, yet it should be provided just once a week to your beardie. Whereas on other days, you may give him a simple calcium powder to fulfill the requirement.

Why do bearded dragons need calcium powder?

A question that might arise here is why do bearded dragons not need calcium in the wild? Well, to put it in easy words, there are innumerable food items that bearded dragons consume daily while they are in the wild. They eat worms, cockroaches, crickets, leafy greens, termites, grubs, beetles, fruits, and a lot more daily, which provides them with all the essential nutrients required for good health.

In comparison to this, in captivity, the food that you provide your beardie can give only a small portion of the required amount of nutrients. This is why supplements are used to overcome or prevent calcium deficiency in a bearded dragon’s body.

What happens if they don’t get enough calcium?

Your beardie will go through mild to serious health issues in case of calcium deficiency. These health complications will shorten the lifespan of your beardie if not resolved on time. In addition, the calcium deficiency in the bearded dragon’s body will make him lethargic, and you’ll see a change in his daily activities and behavior.

In addition to this, in severe cases, this deficiency will result in metabolic bone disease, which weakens the bones and results in deformities in the body structure of the beardie. For example, they might end up having tail rot and brittle bones, which may get fractured easily.

What happens if they get too much calcium?

“Too much of anything is not good..” Can’t stress this statement enough!

Being a newbie (if you’re one), you might end up overdosing on calcium on your bearded dragon, which may bring your beardie down to some health complications as a repercussion of excess calcium in the body.

The excess of bones will make the bones softer and weaker; consequently, they will start calcifying. However, there’s one twist to this problem, feeding excess calcium to your bearded dragon won’t be a problem in the absence of too much vitamin D3. This vitamin is essential for the beardie to absorb calcium; in the absence of vitamin D3, beardie won’t absorb calcium.

In any case, if your beardie has received an overdose of both of these nutrients, then it might experience soft bones, weakness, constipation, lethargic behavior, stiffened muscles, and soft tissues. Excess consumption of Calcium continuously can even result in the death of your bearded dragon.

The influence of cage setup and UVB

You might have provided your beardie with the best cage setup and UVB without any hiding spot to take a break from the heat. However, this might result in the overdose of calcium in the body of your pet reptile. Since UVB provides essential D3 for absorbing calcium inside the body of beardie, you might overdose on the beardie without even knowing it.

Similarly, a less efficient UVB light will stop your beardie from absorbing the required amount of calcium in the body, resulting in metabolic bone disease. So, it’s essential to check your beardie’s cage parameters to avoid any health complications caused by the lack or excess of calcium.

What to consider in the best calcium powder for the bearded dragons?

While looking for the best calcium powder for your bearded dragon, you might wonder about the standards you can check while finding the best calcium powder. A checklist has been provided below to help you decide the best for your reptile.

Phosphorus free

The calcium powder that you’re getting for your bearded dragon must be phosphorus-free as they have enough phosphorus in their diet. The amount of phosphorus for bearded dragons varies according to their age. The table below will shed light on the amount of phosphorus required by bearded dragons of different ages.

NutrientsHatchling-juvenile bearded dragonsAdult bearded dragonGravid Female
Calcium1-1.5% (dry matter)  
Calcium: Phosphorus2:11.5:1Up to 10:1

Vitamin D

Vitamin D is essential for the beardie to absorb calcium in its body; without this nutrient, your beardie won’t digest its calcium. The ideal way to provide Vitamin D3 is through UVB lights; however, if you’re beardie is not getting enough of it, you may use supplements with D3 in it. Moreover, the inclusion of Vitamin D3 in the beardie diet depends on the bearded dragon’s age and health conditions.

Free of harmful impurity

While searching for the best calcium powder, you must ensure to get free of harmful impurities such as metal toxic. These impurities will affect the health of your bearded dragon gravely, even resulting in a shorter lifespan.

Calcium Smell

The food that smells nice is always a pleasure to eat, and beardie’s being a living thing, enjoy the same rule for eating. Also, ensure buying a calcium supplement whose smell doesn’t offend your beardie. Otherwise, your pet will not get close to the food that you’re presenting him.

When to use calcium powder with D3

Without vitamin D3 your beardie will go through different health complications, which include metabolic bone disease. You can determine when to use calcium supplement with D3 only by looking at the efficiency of the light that you have set up for your bearded dragon. If your light does not provide enough vitamin D3, you may use the calcium supplement with D3.

In the other case, if you have installed a mercury vapor bulb, then that alone is enough for providing D3, and you don’t have to give a calcium supplement with vitamin D3.

Worst bearded dragon calcium powder

While you’re choosing the best calcium powder for your beardie, you must also know the worst one to avoid at all costs. First, ensure to select a calcium powder that is finely milled and has no phosphorus element in it, as it can be toxic for the beardie.

The calcium supplements that aren’t milled finely have a hard time sticking to the food, resulting in very little consumption by your bearded dragon.

How do I get my bearded dragon to eat calcium?

Calcium deficiency can be fatal for the bearded dragon’s health, as in the case of calcium shortage, beardie starts drawing the calcium from its bones, which makes them weak and hauls the overall growth and health. There are different ways that you can opt to feed the essential nutrients to your beardie.

The first and easiest way is dusting their meal and feeders with supplement powder. Coat the meal slightly with the calcium supplement before presenting it to the beardie; this will have your beardie munch down the nutrients without even noticing.

The difficulty of feeding the nutrients to your beardie may elevate with their increasing age, as they need more salads in their food; having them dusted can put your beardie off, making them reject the food. In this case, you can use a liquid calcium supplement to add essential nutrients to your beardie’s diet.
