For supplements...its recommended that you use a phos free calcium powder at all feedings but two a months lightly dusted on the insects just before they are fed to the chameleon...and twice a month use a vitamin powder with a preformed source of vitamin A and with D3 in it. Look for words like retinol, retinyl, etc for the vitamin A.
PrEformed vitamin A and D3 from supplements can build up in the system and lead to health issues if overdone....and if not in balance with each other and with the calcium, can lead to bumps on the ribs and tail.
