Keep reading this article for our top picks for calcium supplements.

Why Does My Bearded Dragon Need A Calcium Supplement?

Just like people, bearded dragons need certain vitamins and minerals to maintain their health.

Low levels of calcium can harm the health of your pet.

Because your pet probably doesn’t get a whole lot of natural sunlight every day, they need calcium and vitamin D3 supplements to help them maintain healthy bones and proper development.

Bearded dragons can develop a range of diseases if they are not receiving the proper amount of calcium.

One of the most common diseases your beardie could develop is Metabolic Bone Disease, which is life-threatening if not properly treated.

When you give your bearded dragon calcium, you must also be using a full spectrum light to mimic ultraviolet rays from the sun.

With those rays, the animal will be able to receive vitamin D3 and can properly absorb the calcium.

How Often Does My Bearded Dragon Need A Calcium Supplement?

How often you give your bearded dragon calcium supplements depends partially on their age and also on how much natural sun they receive.

Juvenile beardies often need calcium supplements more frequently as they are still growing and developing.

Calcium is crucial during this time to ensure their bones grow and develop properly.

Juveniles need calcium supplements at least three to four times per week.

In an adult bearded dragon, you might need to add calcium to their food at least once or twice per week.

Be careful not to overdose your bearded dragon, which is possible.

Overdosing of calcium is called hypercalcemia and is fatal in bearded dragons because it leads to their muscles calcifying and hardening.

Hypercalcemia is common when there is an overabundance of vitamin D3 through excessive exposure to UVB lighting.

If your beardie has too much calcium, you might notice it becomes sluggish, constipated, and might have muscle weakness.
