I personally use repashy noD for my calcium without D3 and then repashy calcium plus LoD version for my multivitamin with D3. With this combo the multivitamin is only given 2 times a month say the 1st and the 15th and the calcium without D3 is given at all other feedings. These two have everything so you do not need a 3rd in the rotation.
Keep in mind chameleons kept outdoors and species from higher cooler elevations may only need one LoD dose per month. All dustings should be very light.
