Nutrogrub - NEW Insect Food for Gut Loading

NUTROGRUB is based on a fine vegetable flour which is enhanced with our world leading supplement NUTROBAL and its superfine calcium. This has been a big success and has led to 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 undertaken by an independent laboratory and they impressed even us!
