How Much Dusted Calcium Bearded Dragons Need at Any Age

It is essential to provide enough calcium to your bearded dragon, as it has a critical role in the dragon’s health and well-being. Lack of calcium will cost the health and life of your bearded dragon. However, just as the lack of something is not suitable for the body, the excess of something can also be poisonous to the body of any living thing.

It is essential to provide a diet to your bearded dragon as an owner rich in calcium, protein, and other essential nutrients. The number of nutrients varies from one stage of the bearded dragon to the other one. A young or juvenile bearded dragon needs to have at least 70 percent protein and 30 percent veggies and greens. At the same time, a fully grown-up beardie needs 80 percent veggies and 20 percent of proteins.

Here in this article, we’ll discuss a few reasons why protein is essential for the beardie’s health and what protein should be provided to keep it healthy.

Calcium with or without Vitamin D3.

The UVB light is essential for the absorption of calcium, as this light provides vitamin D3, which works to absorb calcium in the body of a bearded dragon. The type of light that you’re using affects the bearded dragon’s health and decides whether you need to add additional D3 in the diet of your beardie or not.

In the case of using Mercury vapor Bulb, you don’t need to add D3 in the calcium powder that you’re dusting on the dragon’s food. However, in UVB, it is essential to use D3 with calcium for better absorption in a bearded dragon’s body.

Should I Give my Bearded Dragon D3?

Yes, it is essential to provide D3 vitamin (cholecalciferol) to your dragon. If you’re providing enough calcium to your bearded dragon without enough vitamin D3, this will result in a deficiency of calcium. Vitamin D3 mentioned above is suitable for the absorption of calcium. Vitamin D3 is most effective when given in the form of sunlight or UVB light without anything to stop the light from approaching the dragon.

The diet of bearded dragons containing calcium can be presented with or without Vitamin D3. If you’re providing enough UVB light, then there is no need to add a powdered form of the D3, or the amount of D3 can be reduced or stopped all at once. Overdosing of D3 can result in the mineralization of tissues and renal diseases.

Vitamin D3 Oral Supplementation is a Poor Substitute for UVB

It is best to provide Vitamin D3 through UVB light, as giving the vitamin D3 in the diet has been proven to be very ineffective. So you must avoid providing it in the form of supplements; instead, use good UVB lighting to do the deed.

Which Calcium Powder Should be bought for Bearded Dragons?

The recommended powder for providing calcium and D3 is cholecalciferol. Very low levels of cholecalciferol are suitable for the health of bearded dragons when supplied through diet. Purchasing calcium powder both with and without cholecalciferol will give choices to substitute dusting. Avoid buying any calcium powder that has phosphorus in it. Calcium supplements recommended for humans can also be utilized.

The Importance of Multivitamins

It should be kept in mind that besides calcium, the bearded dragon should be given a ​good multi-nutrient a few times a week, according to their age. Try to avoid Vitamins with Vitamin A as they can cause high toxicity to your bearded dragon and even die if provided with an excess of this vitamin.

The vitamins that contain beta-carotene are suitable for the health of the bearded dragons, which benefits the bearded dragon’s body by absorbing only the essential and valuable section of vitamin A. In contrast, the unwanted portion of this vitamin is passed out without any trouble.

It is essential to provide your dragon with multivitamins when you think the UVB light is not enough or when the dragon doesn’t get the right amount of calcium.

Why your bearded dragon needs calcium:

There are a few reasons why your beardie needs to have enough calcium to stay healthy. Besides different minerals like phosphorus, calcium isn’t something your bearded dragon will get enough from their eating routine.

This is nothing compared to the grounds that calcium (and nutrient D3) is quite the most important and fundamental minerals these creatures can get. It is essential for the ability of the dragon to grow and for good bone health. However, the exciting part is the inability of the bearded dragons to use and absorb calcium without nutrient D3. They need both to work!

While they can get a good portion of D3 from the UVB lighting, it’s typically insufficient (99.9% of the time). This implies the need to enhance these for your bearded dragon in the form of supplements to stay sound.

What Happens If They Don’t Get Enough?

The lack of calcium inside the body of a dragon can cause various health issues. Among which some issues are worse as compared to the others. Some apparent symptoms of the bearded dragon are lower energy level, less movement. The calcium deficiency can cause the metabolism to slow down, for which you’ll see the dragon twitching their tails or acting skittish.

Worse conditions are acting lethargic and getting weak, as the bearded dragon is a victim of calcium deficiency. These issues are very potential health risks and must be adhered to at the earliest. Furthermore, calcium deficiency affects the bones and can cause deformities in the bearded dragon’s body. The situation may worsen, causing the tail of the dragon to rot.

Providing enough calcium to the bearded dragon will make him strong against bone fractures and other diseases.

What Happens If You Give Them Too Much

The excess of calcium, just like calcium deficiency, is not good for the health of bearded dragons. Many new owners of the bearded dragons make the mistake of providing the calcium more than what’s typically required by the bearded dragon. This can cause health issues in the bearded dragon, which can worsen if not taken care of on time.

It should be kept in mind that providing too much calcium cannot cause any damage in the absence of an equal amount of D3 provided through UVB light. As the calcium won’t be absorbed in the body in the same amount as provided. However, consuming an excess of both the vitamins is alarming.

Excess of these nutrients can cause constipation, general weakness, and lethargic behavior of the bearded dragon. The lack of movement or lethargic behavior is a consequence of the stiffening of soft tissues in the body of the beardie, which happens because of the excess of calcium. Providing an excess of these nutrients without any gap can result in the death of the bearded dragon.

The influence of Cage setup and UVB:

Sometimes, you may provide excess calcium to your beardie without even knowing it. The most common way of this happening is a suboptimal light and habitat. Having a cage with proper UVB lighting is the first step for them to get the calcium naturally.

However, having a cage with less space and nowhere to hide to take a break from basking can give the dragon an overdose of the nutrients that are required for the well-being. To avoid this situation, make sure to have ample space inside the cage and a hiding spot for your bearded dragon to take a break whenever it wants. The beardie itself can be the best judge of when the vitamin is getting more than the required amount.

Should I feed my bearded dragon Calcium?

Feeding calcium to the bearded dragon is recommended husbandry practice, and it helps to prevent hypocalcemia. However, if you’re providing a commercial diet to your bearded dragon, it already contains the required supplement. Hence there’s no need to give supplements separately. Make sure you check the ingredients of the food that you’re providing your pet.

Calcium provides nutrients to perform body functions including, Skeleton formation, muscle contraction, mineralization of bones matrix, and blood clotting.

Does my Bearded dragon need Vitamin D:

The importance of vitamin D for a bearded dragon can’t be stressed enough, as this vitamin is essential for the absorption of calcium and other nutrients in the bearded dragon’s body. The body is unable to use the calcium if it doesn’t have enough Vitamin D.

This Vitamin is essential for many body functions such as the functioning of nerves and muscles, reproduction, cardiovascular health, and immune system of the bearded dragon body.

There are more ways to get Vitamin D3 Than Using a Supplement

There are different ways to supply vitamin D3 to your bearded dragon; the first is to provide UVB light that interacts with the epidermis of the beardie’s skin and absorbs all the required amount of D3.

Another way of providing D3 is through supplement through food and supplement.

The liver processes nutrient D2 into 25-hydroxyvitamin D2 and nutrient D3 into 25-hydroxyvitamin D3. Together they are considered to be calcifediol.

Nutrient D2 (ergocalciferol) comes from plant sources, and nutrient D3 (cholecalciferol) from plant and creature sources. The nutrient D2, when provided in the food, doesn’t replace the requirement for nutrient D3.

Retained nutrient D can be stored in the body like the fat tissue, kidneys, and liver.

How much calcium do bearded baby dragons need?

As baby beardies are growing rapidly, they need to have their food flooded with calcium around 4-5 times each week, and once a day only.

Also, you will need to supply your baby bearded dragon with a multi-nutrient (as examined above) around 2-3 times each week, blended in with their calcium powder, and never more than one time each day.

How much calcium do Adult bearded dragons need?

As grown-ups, the bearded dragons don’t need calcium very frequently, given that they are done growing and have reached adulthood. It is recommended to dust the food of an adult bearded dragon at least three times a week. 

The multivitamins that you’re providing your bearded dragon should be mixed with calcium just once a week.

What happens if My Bearded Dragon Gets Too Much Calcium?

As Calcium deficiency is far more typical than an abundance of calcium, some medical problems can emerge with the excess of calcium in the body of a bearded dragon.

When an excessive amount of D3 is consumed and significant amounts of calcium exist in the food that you’re offering, then the bearded dragon can encounter Hypercalcemia.

Hypercalcemia happens when there is an excessive amount of calcium in the blood and can affect the bearded dragon’s health, and in severe cases, it can cause your bearded dragon to die.

When bearded dragons are exposed to very high UVB lights, they get a very high amount of D3, which lets the dragon absorb all the calcium provided, which can harm its health. When they are given an excessive amount of calcium powder, their muscles would become weak and won’t be able to stretch easily.

So it’s important to adjust their diet and the UVB light to avoid any complications.

How Often do you Give a Bearded Dragon Calcium?

How frequently you give your bearded dragon calcium with D3 incredibly relies upon the measure of UV light exposure. Bearded dragons given time outside in direct daylight will require lower supplementation, unlike those kept indoors.

Providing calcium to a bearded dragon every day is not essential. The amount of calcium and vitamin D3 that different vets and herpetologists suggest is mentioned below:

Young3-4 times a week
AdultsAt least once per week
Reproductively active FemaleThree to four times a week
Adult receiving sunlightOnce every two weeks
