It has beta carotene in it and there is debate over whether it can be converted into vitamin A. I have used it for 5 years and have not had any eye problems with my chameleons until just recently. I am pretty convinced the problem I had did not have to do with vit A but an eye injury. Use fruits and vegetables in your gutload that have vit A also for added protection. It is really up to you. I know other members who use Repashy Calcium plus(I use that also) that contains vit a and also Reptivite does as well.
I don't use Reptivite, but I know others that do and they have said it contains Vit A and that is why they use it. You can go online and research it and find the label and see. I am not sure.
