here are the ingredients in Nupro .... from:
nuprosupplements.com/ingredients.htmDESICCATED LIVER:The ultimate in palatability!
The fresh, natural flavor of real liver is wonderful for the finicky eater! Supplies iron and B vitamins.
Just add water to make a Grrreat Gravy that Dogs Crave!
NORWEGIAN KELP:A natural seaweed - A rich source of trace minerals including iodine, used for proper glandular function and metabolism. An excellent source of vitamins A, B1, B2, C, and E. These vitamins are beneficial for maintaining proper health and are responsible for the growth of bones, a healthy heart rate, a sound central nervous system, and helping muscles stay firm and strong. Norwegian kelp grows deep in the ocean, mostly in cold waters, so it contains valuable nutrients from the ocean floor. Aside from nourishing the glands, it is beneficial for overall good health. Supports healthy pigmentation and coat highlights.
AMINO ACIDS & ENZYMES:A wide array of naturally available Amino Acids and Enzymes helps the body to maintain healthy hormonal balances and to fortify a resilient Immune System.
IMPORTED YEAST CULTURES:Helps maintain a full and healthy coat which may minimize the occurrence of excessive shedding and dry skin. Provides proteins, zinc and biotin. Best source of B vitamins. Most companies use cheaper brewers yeast which can be a combination of hops, corn, grains, wheat, etc., whatever comes from the brewery. Many animals have grain allergies, and brewers yeast may further aggravate an allergy condition. With nutritional yeast cultures, grown on sugar beets, a veggie source, NO grains are present at all. Something to think about when reading ingredient labels.
FLAXSEED :Provides essential omega fatty acids. Most absorbable vegetable fatty acid for the canine. Rich in omega 3 fatty acids, alpha-linolenic acid, fiber and lignans. Helps maintain healthy, shiny fur and soft skin.
LECITHIN: A rich source of choline, required by the body to make acetylcholine, is a neurotransmitter essential for normal healthy nerve and brain function. Supports healthy liver function.
GARLIC CONCENTRATE:Wonderful ingredient that does so much for the body. Garlic contains allicin, a powerful antioxidant. Supports a healthy immune and cardiovascular system.
LACTOBACILLUS ACIDOPHILUS:Promotes healthy digestion which may reduce the occurrence of flatulence. Because NUPRO® is in a powdered form and not from concentrate, it is easily assimilated into the system and digested with the dog’s food. There is no sense in giving an animal this superior product if they don’t digest it properly. Also promotes friendly bacteria in intestinal tract.
CALCIUM CITRATE: Calcium is best absorbed in an acidic environment, hence calcium citrate is the best absorbed supplemental form of calcium---it does not require extra stomach acid for absorption. Intended to provide nutritive support for healthy bones, teeth and nerve function.

Both contain plant extracts including flax. That can irritate some dogs. There are different formulations of each as well, some with joint supplements, etc.
It may be a matter of trying each and seeing which your pups do best on. I don't notice too much difference between them as supplements as far as how Brody tolerates them so I switch off. I'm not a fan of the molasses in the Missing Link or the rice bran. Brody has a slight preference for Missing Link over Nupro. He hates the smell of Nupro.
