Every reptile owner knows that calcium is essential to proper bone growth in their pets. Mealworms are deficient in calcium. Fluker’s Hi Calcium Mealworm Diet enables reptile keepers to gut-load feeder roaches in order to increase their vitamin and mineral content prior to offering them as prey. In addition, this product serves as a bedding for your mealworms. This veterinarian-formulated diet establishes a positive calcium-to-phosphorus ratio in live mealworms which enables reptiles to benefitnot only from the nutritional value of the mealworm itselfbut from the insect’s nutrient-rich, gut content as well. This is the only mealworm diet clinically proven to create a positive calcium to phosphorus ratio in mealworms when fed as directed!
