Both the blue and pink labeled bottles (RepCal) are common brands and work very well. The one caution I have is for the vitamin A. It can be very dangerous and is very easy to overdose your pet with it. Most people who use the straight vitamin A that I know offer it only 1 to 2 times a month and only to their breeding adult pairs. Just offering the information up as a precaution. The Blue Multivitamin is what I used for the first 4 or 5 months I had my frogs. It seems to work very well
