Its superfine vegetable-based formula balances protein to prevent premature insect growth, ensuring optimal nutrition for reptiles and insectivorous pets. Independently lab-tested and highly rated, Nutrogrub is the go-to supplement for professional-grade insect feeding. ## Description Product Description Vetark have spent several years working with their insect feeds BUG GRUB and GRUB GRUB to develop a single product which covers the needs of both groups (hoppers and mealworms) and to produce the best gut loading effect we can. Now we have NUTROGRUB - based on a fine vegetable flour enhanced with our world leading supplement NUTROBAL and its superfine calcium. This has been a roaring success and has resulted in increasing calcium levels in crickets by MORE THAN TENFOLD ie x 10, and in mealworms MORE THAN SEVEN FOLD ie x 7. The tests were carried out by an independent laboratory and impressed even us! The protein level is low enough that the mealworms don't mature too quickly, but more than adequate for support of the feeder insects. Gut loading is useful in increasing calcium levels but for belt and braces we still always recommend dusting with Nutrobal as well.

Worked well and we managed to fledge two of them.
