I know that brand..."Eggland's Best". Eggland's also sells free range eggs and pasture raised eggs, neither of which is vegetarian because the chickens eat bugs and worms.
Ironically, Eggland's claims those have "superior nutrition" LOL:
- Pasture Raised & Free Range Eggs with Superior Nutrition
- Our chickens eat better so you can, too
- More than Double the Vitamin B12, 10X More Vitamin E, 6X More Vitamin D Compared to Ordinary Eggs
If chickens don't get an amino acid called methionine from eating bugs and worms, then it has to be supplemented.
