Though not much as compared to animal protein, cauliflower also offers a small portion of protein.

Protein is crucial towards the growth and development of all reptiles including bearded dragon.

And its deficiency can affect the development of young bearded dragons. For young bearded dragons, they might not be able to chew through cauliflowers. Feeding them a softer cauliflower can come a long way to help them chew it.

Vitamin and minerals

Vitamins and minerals are very crucial through out the life of bearded dragons.

Some of the vitamins present in cauliflower include vitamin K, B-6, and C. Vitamin K is normally synthesized from the bearded dragon intestinal flora.

Calcium can be obtained from both food and supplementation through dusting of bearded dragon food.

Young bearded dragon will need more calcium compared to the adult dragons.

However, you should watch out for food that has a high amount of oxalates and phosphorus. These minerals will reduce calcium absorption in bearded dragons.

When calcium reacts with oxalates it forms calcium oxalates and calcium phosphate when it reacts with phosphorus.

Consequently, food with these minerals especially oxalates should be fed sparingly or avoided altogether such as avocado.

The recommended ratio of calcium and phosphorus is either 1:1 or 2:1.

Iodine is needed for growth and development, reproduction, and skin shedding. Therefore, with low iodine levels, these processes will be highly affected.
