The first ingredient in this dog food is salmon meal. Because it is considered a meat concentrate, fish meal contains almost 300% more protein than fresh fish itself.
Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1
It’s important to note that the next 3 ingredients included in this recipe are each a type of legume:
- Faba beans
Although they’re a mixture of quality plant ingredients, there’s an important issue to consider here. And that’s the recipe design practice known as ingredient splitting.
If we were to combine all these individual items together and report them as one, that newer combination would likely occupy a significantly higher position on the list.
In addition, legumes contain about 25% protein, a factor that must also be considered when judging the meat content of this dog food.
The fifth ingredient is sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.
The sixth ingredient includes chickpeas, also known as garbanzo beans. Like peas, beans and lentils, the chickpea is a nutritious member of the fiber-rich legume (or pulse) family of vegetables.
However, chickpeas contain about 22% protein, a factor that must be considered when judging the actual meat content of this dog food.
The seventh ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The eighth ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The ninth ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Supreme Source product.
With 5 notable exceptions…
First, we find fish oil, which is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.
Depending on its level of freshness and purity, fish oil should be considered a commendable addition.
Next, we note the use of dried seaweed meal, a product made from a family of brown algae known as Fucaceae (Rockweed). Although it does contain a number of healthy nutrients, seaweed meal is primarily used as a source of inexpensive carbohydrates (about 60% dry matter).
This item is only rarely used to make pet food and is more typically found in feeds for cattle, horses, hogs, hens and sheep.
In addition, we find taurine. Taurine is an important amino acid associated with the healthy function of heart muscle. Although taurine is not typically considered essential in canines, some dogs have been shown to be deficient in this critical nutrient.
Since taurine deficiency appears to be more common in pets consuming grain-free diets, we view its presence in this recipe as a positive addition.
Next, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, this food contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Judging by its ingredients alone, Supreme Source Grain Free looks like an above-average dry dog food.
As a group, the brand features an average protein content of 29% and a mean fat level of 13%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.
And a fat-to-protein ratio of about 44%.
Above-average protein. Below-average fat. And near-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the various legumes, this looks like the profile of a kibble containing a moderate amount of meat.
Our Rating of Supreme Source Grain Free Dog Food
Supreme Source Grain Free is a dry dog food using a moderate amount of named meat meals as its dominant source of animal protein, thus earning the brand 4 stars.
However, it’s unfortunate the company chose to include so much plant-based protein in its recipe. Otherwise, we would have been compelled to award this product a higher rating.
