Its superfine vegetable-based formula, enhanced with Nutrobal supplement, balances protein to support insect health without accelerating maturation, making it the go-to choice for reptile enthusiasts seeking premium nutrition and longer-lasting feeder insects. ## 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.

Thanks.** A: Yes you can use the Nutrogrub with roaches and wax worms. **Q: Can I use this for the live food my leopard gecko eats please? Thx** A: Yes you can. We use it to feed black crickets and meal worms for our Leopard Gecko. **Q: Is this suitable for feeding to locust, for my Pacman Frog to eat?** A: I looked into the use of Nutrogrub for loading mealworms to feed to house-martins (nest had collapsed). Worked well and we managed to fledge two of them. There were several references to this use for reptiles and amphibians. ## Frequently Bought Together - Vetark Nutrogrub, bug food containing protein, calcium vitamin D3 for feeding insects, 300 g powder - ProRep Bug Gel Jar Pack 500ml | Health Care for Reptiles & Amphibians | Bug Hydration --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/53397885-vetark-nutrogrub-bug-food-containing-protein-calcium-vitamin-d3-feeding](https://www.desertcart.hr/products/53397885-vetark-nutrogrub-bug-food-containing-protein-calcium-vitamin-d3-feeding) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
