Corns may have several nutrients your dragon needs. But, despite all the benefits, there is also a problem that you need to know about this grain. Corns have eight times more phosphorus than calcium. This is way over the ideal ratio for bearded dragon diets. 

The ideal ratio for calcium to phosphorus a bearded dragon need is 1:1 to 1:2. Anything over will be a problem. Excess phosphorus will bond with the calcium and prevent the calcium from being absorbed into your dragon’s bloodstream. This isn’t good, especially for growing beardies. 

Pro-Tip: To balance the ratio out a bit, you can add a sprinkle of calcium powder supplements on their corn.

How Often Can Bearded Dragons Eat Corn?

Your beardie shouldn’t have corn often. At most, these grains should only be added to their meals once a month. Despite being delicious, corn has lots of water and phosphorus. These are not things that a dragon often needs to have or need a lot of.

A few kernels each month is a healthy amount for your dragons. Any more than this, and it may cause discomfort for your beardie. Also, do not give them corn if you have already fed them other fruits in the last few weeks.
