DogfoodAdvisor subscribes to the naturalistic fallacy in their reviews.
But the bottom line is that synthetic K3 is more shelf stable than naturally derived K1 and K2. What good is “natural” if it breaks down before being consumed?
I’m not afraid of chemicals and natural isn’t better. Last time I checked, nature was trying to kill me.
What good is synthetic if it’s been banned for human use because it kills people?
You do what you want.
I do not buy dog foods with a 50 year shelf life.
All my brands have a year or less expiration dates.
They don’t need to embalm their products.
