It is in theory, to feed a "supposed" high vitamin source encapselated food that "supposedly" the cricket cannot digest, the lizard in theory is supposed to benefit from the gut contents.
The problem being that the lizard cannot digest the food, the cricket can, so it is a lie to sell an overpriced product.
Just feed your crickets, keep them healthy, hydrate them, and all is well. Whatever diet the crickets eat and do good on benefits the lizard and the crickets, its that simple.
