Recipe and Label Analysis

Supreme Source Salmon Meal and Sweet Potato was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Ingredients Analysis

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
• Lentils
• Peas

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 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, chickpeas are 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 pea starch, a paste-like, gluten-free carbohydrate extract probably used here as a binder for making kibble. Aside from its energy content (calories), pea starch is of only modest nutritional value to a dog.

The ninth ingredient is chicken fat. This item 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 tenth ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

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 three notable exceptions…

First, although alfalfa meal is high in plant protein (about 18%) and fiber (25%), it can be less common to find it in a dog food recipe.

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.

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.

Nutrient Analysis

Based on its ingredients alone, Supreme Source Salmon Meal and Sweet Potato looks like an above-average dry dog food.

The dashboard displays a dry matter protein reading of 29.9%, a fat level of 13% and estimated carbohydrates of about 40.4%.

As a group, the brand features an average protein content of 29.9% and a mean fat level of 13%. Together, these figures suggest a carbohydrate content of 40.5% for the overall product line.

And a fat-to-protein ratio of about 44%.

Above-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.

Even when you consider the protein-boosting effect of the various legumes, flaxseed and alfalfa, this looks like the profile of a kibble containing a notable amount of meat.
