Most reptiles are unable to convert beta carotene to vitamin A efficiently. They rely on preformed vitamin A in their diet to meet their metabolic needs. Inefficient conversion of beta carotene to vitamin A is why reptile diets often contain sources of preformed vitamin A such as liver or insects.
Retinyl palmitate is the most common form of dietary vitamin A.
Cianocobalamin or Hidroxocobalamin (the most effective form) are known by vitamin B12.
The most common element in a molecule of vitamin D is carbon, which is a fundamental building block of organic compounds. Additionally, vitamin D contains hydrogen and oxygen atoms, contributing to its structure. The specific form of vitamin D, such as vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol), may vary slightly in composition but primarily consists of these elements.

Vitamin A1 is the most common form of vitamin A found in animal sources like eggs and liver, while vitamin A2 is found in smaller amounts in dairy sources like milk and certain types of cheese. Both forms can be converted to the active form of vitamin A (retinol) in the body, but vitamin A2 is believed to have a slightly different absorption rate and metabolic fate compared to vitamin A1.
