"There are several forms of vitamin D.
"Vitamin D without a subscript (the tiny 3 behind the D, for example) refers to either D2 or D3 or both. Either form will be converted to a biologically active form, one that the body uses whatever it needs the vitamin D for.
"The two major physiologically relevant forms of vitamin D are D2 (ergocalciferol) and D3(cholecalciferol). Vitamin D3 is photosynthesized in the skin of vertebrates by the action of solar ultraviolet (UV) B radiation. Vitamin D and D2 are processed in the body to produce whatever form of vitamin D is needed - so as long as there is some vitamin D present, and the liver and kidneys are fully functional, then vitamin D will be converted to the appropriate form.
"The whole process is rather complicated, this is just a quick and simple summary. If you want to look into it in detail, Google will have the answers for you.
"Saying there is vitamin D in the supplement is all that's needed, the body will make the other forms. If you have a sick animal, compromised liver or kidney function, then it's better to supply the specific form of vitamin D. It is assumed you're using it for a healthy animal, if it's sick, you'd be taking it to a vet who could prescribe the appropriate form according to the gecko's condition.
"The supplement in question says it contains all the essential vitamins, minerals and trace elements. Since this is a very reputable product, it's quite safe to assume that it also means it includes the appropriate form(s) of vitamins, including vitamin D."
