Bearded dragons in captivityīearded dragons in the wild don’t need supplementation. Since they cannot get these in correct amounts from their food, supplements are necessary. They should receive a multivitamin 3-5 times per week, calcium 4-7 times per week, and vitamin D no more than 3 times per week. Whether it’s a complete lack of supplementation, or an inattention to the quality of those supplements, not supplementing correctly can lead to a wide range of health problems for bearded dragons kept as pets.īearded dragons should be given 3 basic supplements in addition to a healthy diet. That is one of the many possible reasons that some bearded dragon owners dismiss the importance of buying supplements for their beardies. For humans, the supplement industry has grown into a multi-billion dollar behemoth full of hucksters and charlatans. That word can evoke strong reactions among some people.
