剛剛進去我平常會去Chameleon Forums, 特別複習了一下關於D3的用法，他們的意見跟我一樣，含D3的鈣粉不需常用，他們建議每兩週用一次就好了。純鈣粉可以每次都沾上很少（注意次次用的話是很少“lightly dusted")來餵。多種維他命也是兩週一次（若兩週一次就多一點吧：我個人的話是每週兩次，但每次都很少很少）。
(以下quote原文給您參考）
Calcium and other vitamins are very important to your chameleon's health. Feeder insects should be lightly dusted with powdered supplement before being fed to your chameleon. Many keepers successfully use calcium (without D3 or phosphorus) at nearly every feeding, multivitamin once every 2 weeks, and calcium with D3 once every 2 weeks.
