No, bearded dragons cannot eat green leaf lettuce.
Bearded dragons are omnivores who require both plant matter and animal protein in their diets.
Green leaf lettuce has very little nutritional value for bearded dragons.
It doesn’t have any fat or cholesterol, so it’s good for feeding animals with high cholesterol.
It can also be safely fed to sick animals because it’s low in calcium, sodium, and protein.
Although green leaf lettuce is extremely low in all of these nutrients, it still has no nutritional benefits for bearded dragons even when fed as the only part of their diet.
The dark leaves of the green leaf lettuce will not be recognized as food by a bearded dragon and will go uneaten.
This leaves only the white part, which contains no nutritional benefits for bearded dragons either.
