have you tried zoo-med? I am sure there isnt much taste difference between brands. i have never tasted the stuff so i cant really say lol. But another alternative is gut-loading which may be better than dusting if you know what to feed your feeders. What I would do is use roaches for this because they will eat more food for there body size then most other feeers. Feed them romain lettuce for the calcium. (romain lettuce contains more calcium then milk) cereal such as Cheerios and Total have a suggnificant source of vitamin d3 and calcium. You will have to check the lable on the box to find which has the best source for D3 and Calcium. Gut-loading is also a great way to deliver other vitamins and minerals. when you introduce the food items to your insect feeders be sure to wait at least 12 hours before feeding them to your frog. This will give the insects plenty of time to eat their fill of the nutrient rich foods that will pass to your frog.
