NLS is better based on ingredients... NLS contains some nice meat ingredients, vitamins from fruits and veggies, garlic to boost the immune system, and spirulina. Even if Omega One has nice first ingredients, I'm not exactly sure it has these.. It has wheat gluten, (cheap filler) and ethoxyquin which is proven to cause cancer, it's a preservative.
I'm sure everyone here recommends Omega One just because their availability and color enhancer, yes? No one seems to be mentioning any of the ingredients..
