So you know I was just thinking about this earlier today actually. I'm a dietitian (nutritionist) and one thing that we tell patients and clients is that you shouldn't really need to take supplements as long as you are eating a healthy diet. The human body absorbs nutrients better from food than we do from supplements anyway, so getting most of our nutrients from food is better for us. In the wild frogs don't eat dusted insects, so my question really is why do we need to supplement the insects we give them in captivity? I've read things that say in the wild frogs eat a more varied diet than they do in captivity, which can be true if you don't feed a variety of insects, and also that frogs like Pacman eat larger animals with bones such as baby rodents or birds which provides more calcium. Anyway, sorry about the rant it was just funny that I happened to see this today after having this thought so I thought I'd share . So to answer your question everyone says you are supposed to dust your insects so I do a Repashy calcium plus dusting every other week and it seems to be working fine. The Repashy calcium plus has calcium, vitamin D3, and a multivitamin. The difference is that some people do a calcium + vitamin D3 dusting and then a multivitamin dusting separately because people think that when they're combined they are not absorbed as well. However, again I think this is kind of silly because if you are gut loading your insects, which you are with those veggies, the crickets should be providing plenty of vitamins and minerals without the dusting. The other thing about combining vitamins and calcium is that they are combined naturally in a ton of foods like spinach and kale for example so I don't see a problem with it. I would suggest doing your own research though, I'm just using my judgement based on what I've learned in the many years of school and practice I've had with nutrition and the human body. I guess frogs may be different?
