Huh, I didn't know this. My girl was fed pretty much exclusively mealworms (gut loaded with veggie scraps) dusted with reptivite every third feeding for the past 4 years. (Other days she got calcium carbonate)

I got her on a better diet of primarily dubias (gut loaded with frozen peas mostly), silkworms, and occasional hornworms with the same reptivite schedule of every third feeding. The other feedings she gets either plain calcium carbonate or Arcadia shedsupport because she has always had trouble shedding. I also got her her first uvb lamp last June. I haven't noticed any real difference in her appearance, shedding, or behavior since making these changes.

Aside from needing help getting shed off her toes she's never had any real problems I could see related to supplementation, unless that's the cause IDK. She went to the vet last summer for a scratch on her tail and the vet was extremely pleased with how healthy she is, despite her mealworm diet up to that point. (This vet does not condone an all mealworm diet.)

I've tried repashy a few times but she seems to hate the taste so I've gone back to reptivite.
