Vitamin A is a fat-soluble vitamin required for healthy skin, mucus membranes, eyes, muscles, teeth, and other parts of the body. It is also necessary for growth, immunity, and reproduction. Like vitamin D, humans “make” our own vitamin A from the beta carotene we get from vegetables. However, recent studies suggest that chameleons are unable to convert beta carotene into the vitamin A that they need.
Vitamin A toxicity is the opposite problem (too much vitamin A, rather than too little), but is much rarer now than it was 30 years ago when keepers first started to voice concerns.
(2x/month for adults) should provide the vitamin A that your chameleon needs without risking overdose. Refer to our page, Feeding Your Jackson’s Chameleon, for more information.
