The chicory root aids digestion.
Rosemary is used as a natural preservative, however it's been shown to cause seizures in humans, so I would want to know how much is being used.
Alfalfa is a natural antioxidant and can aid in hip and joint pain from inflammation. It has a lot of nutrients in it and is beneficial. (I actually take alfalfa and chylorpyll to raise my hgb)
Vitamin D is something we all benefit from-it helps the intestines absorb calcium. I would not use a fish Liver oil (cod or tuna) or other vitamin d supplements if my commercial food contains vitamin d as you can overdose on it. It is fat soluble, meaning it's stored in the liver.
Flax seed is a excellent source of omega-3 fatty acids, which are essential for skin and coat. It's better if used fresh.
Salmon meal is considered a meat concentrate and contains nearly 300% more protein than even fresh salmon. It is particularly rich in omega-3 fatty acids.
Brewer’s yeast is the yeast that’s left over from making alcohol. Dogs seem to like the taste, so it's used for flavor. It’s full of B vitamins which are good for skin, coat, and carbohydrate metabolism.
