Best Bearded Dragon Calcium

Bearded dragons in captivity rely on you to help them get the calcium they need to maintain healthy bones and overall health. Choosing between powdered calcium, liquid calcium and sprayer options may seem daunting, but once you have made the choice that works best for you and your dragon, you will find you have a happy and healthy beardie on your hands.

All bearded dragons need calcium in their diets. Those in the wild eat a much wider variety of greens and insects, but in captivity their selection is limited and therefore you need to supplement their diet to ensure their overall health.

Why Do Bearded Dragons Need Calcium

Before you take a closer look at the different calcium supplements and identify which one is the best choice for you and your beardie, you need to have a better understanding of your dragon and their dietary needs.

In the wild, a bearded dragon will get calcium from their choice of insects and greens. They eat a much wider variety of foods in the wild than they do in captivity. In addition to this, bearded dragons are known to eat small animals from time to time, getting all the calcium that they need.

In captivity, you will be recommended to give your bearded dragon two supplements, which are calcium and Vitamin D3. Vitamin D3 is essential as it helps your bearded dragon absorb the calcium effectively. In your vivarium you will have a UV light. UVB is essential in providing the needed Vitamin D3 for your dragon. If you don’t have a full spectrum UV light in your enclosure, then it is worthwhile considering a Vitamin D3 supplement as well.

Younger bearded dragons often suffer metabolic bone disease due to a lack of vitamin D3 and calcium. They often have pathological fractures, deformities and seizures. Adult bearded dragons also need calcium, though they don’t require as much as younger dragons, as their growth has slowed.

Feeding Calcium to Your Dragon

There are a few options when it comes to calcium supplements for your bearded dragon, eat one has a different way in which it is used, these include:

  • Powder – Powder calcium is one of the most popular options. It’s quick and easy to use. Put your insects or greens into a bag or container and lightly dust with calcium powder as per instructions. Shake, remove and feed.
  • Liquid – Liquid calcium is often administered by using a small syringe and gently encouraging your bearded dragon to drink. If you are not comfortable with this, then you can use the recommended dose by adding it to your dragons drinking water.
  • Spray – Most of the calcium sprays you find on the market have Vitamin D3 in them. The spray is useful for adding calcium to greens before feeding.

How to dust Calcium powder with crickets

You can use a sugar shaker to dust the crickets or put everything in a plastic bag and shake.

How Often Should Bearded Dragon Have Calcium

The amount of UV exposure your dragon has will determine how often you give your beardie calcium and Vitamin D3 supplements. Those that are kept indoors all of the time will require more supplements than those that are allowed to play outdoors in a secure enclosure for a period of time.

The good news is that you don’t have to give your dragon calcium supplements every day. How often you give your beardie calcium is determined by a number of factors:

  • New babies – Calcium should be given daily.
  • Juveniles – three to four times per week.
  • Adults – Once or twice a week.
  • Females that are reproductively active – three to four times per week.
  • Adult receiving regular sunlight – once every second week.

Bearded Dragon Calcium Overdose

You are probably already wondering if its possible to give your bearded dragon too much calcium supplement, and the answer is yes. Remember that your dragon needs Vitamin D3 in order to absorb calcium. Without Vitamin D3, any calcium you give your dragon is pointless. Too much Vitamin D3 mixed with too much calcium can be a very dangerous combination.

Too much calcium in the blood is called hypercalcemia and this can occur within your beardie. Too much calcium can result in a sick beardie. In extreme cases it can be fatal. Overdosing on calcium will reduce how much fat your bearded dragon uses, along with how much protein, minerals, and other vitamins it stops using. Muscles start to calcify and muscle hardening will occur. This is often seen in bearded dragons that have been exposed to too much UVB light in conjunction with supplements of calcium and Vitamin D3.

If you provide your dragon with a good full spectrum UVB light, then you may not have to supplement Vitamin D3, which can reduce the risk of overdosing on calcium.

Calcium Overdose Signs and Symptoms

  • Muscle weakness
  • Constipation
  • Lethargy

Bearded Dragon Calcium Deficiency

There are a number of causes why your dragon may be suffering from calcium deficiency and these include anything from dietary issues to poor UVB lighting and heating. Calcium deficiency is also experienced in dragons that are going through a biological stage, such as a growing young dragon, for example.

Often a bearded dragon owner will find their beardie suffering from calcium deficiency even though they are giving them dusted insects. This could be that the amount of coating on the insect isn’t enough or the calcium isn’t sticking to the food. The other possible option is the calcium to phosphorus ratio. The calcium to phosphorus ration should be 2 to 1.

Symptoms of Calcium Deficiency

Calcium is essential to the growth of your dragon. The same as in humans, calcium is needed to grow strong bones and maintain the strength. Dragons that are suffering from calcium deficiency will have weak bones, which is often picked up by having a number of fractures on a regular basis.

Choosing The Right Calcium Supplement

There are a few things to take into consideration when it comes to choosing the right calcium supplement for your bearded dragon. The three main things to focus on when making your final selection should include:

  • Phosphorus free – Bearded dragons do get more phosphorus from their vegetable diet. Whether the calcium has phosphorus or not should be decided based on their current diet to ensure an even level of phosphorus and calcium in the body, both are essential to the dragon’s bone health.
  • With or without Vitamin D3 – this should be determined based on the quality of UVB lighting you are providing in your enclosure and whether your dragon spends any time outdoors in the sunshine.
  • Powder, liquid or spray form – This should be based on what is easiest and most comfortable for you to use and what your beady prefers.
