NutriSource Grain Free Dog Food receives the Advisor’s mid-tier rating of 3.5 stars.
The NutriSource Grain Free product line lists 17 dry dog foods.
Each recipe below includes its related AAFCO nutrient profile when available on the product’s official webpage: Growth, Maintenance, All Life Stages, Supplemental or Unspecified.
Important: Because many websites do not reliably specify which Growth or All Life Stages recipes are safe for large breed puppies, we do not include that data in this report. Be sure to check actual packaging for that information.

The first ingredient in this dog food is boar, an animal closely related to wild pig. Although it is a quality item, raw boar contains up to 73% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.
After processing, this item would probably account for a smaller part of the total content of the finished product.
The second ingredient is turkey, another quality item inclusive of moisture.
The third ingredient is turkey meal. Turkey meal is considered a meat concentrate and contains nearly 300% more protein than fresh turkey.
The fourth ingredient is menhaden fish meal, another protein-rich meat concentrate.
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 three ingredients included in this recipe are each a type of legume:
- Green lentils
- Red lentils
- Garbanzo 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 eighth ingredient is sunflower meal, a by-product of the oil extraction process – and an item more typically found in feed for livestock.
Although sunflower meal contains about 34% protein, it would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
The ninth ingredient is sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.
Sunflower oil is notable for its resistance to heat damage during cooking.
There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this ingredient.
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 product.
With seven notable exceptions…
First, we find chia seed, an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.
However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.
Next, 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.
In addition, brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.
Fans believe yeast repels fleas and supports the immune system.
Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.
In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.
In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.
What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.
Next, this recipe includes taurine, 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.
Additionally, we find dried fermentation products in this recipe. Fermentation products are typically added to provide enzymes to aid the animal with digestion.
Next, 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.
And lastly, this recipe includes selenium yeast. Unlike the more common inorganic form of selenium (sodium selenite), this natural yeast supplement is considered a safer anti-cancer alternative.

Dog Food Review
Judging by its ingredients alone, NutriSource Grain Free dog food looks like an above-average dry product.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
As a group, the brand features an average protein content of 30% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 45% for the overall product line.
And a fat-to-protein ratio of about 57%.
Near-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the lentils, garbanzo beans, sunflower meal, chia seed and brewers yeast, this looks like the profile of a kibble containing just a moderate amount of meat.
NutriSource Grain Free is a dry dog food using a moderate amount of named meat meals as its main source of animal protein, thus earning the brand 3.5 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
