Found this too, thought this was pretty interesting. It lists the ingredients in Missing Link and the reasons they are beneficial to dogs.

Alfalfa
(Medicago Sativa)
One of nature's most powerful and nutritious plants. The human body absorbs nutrition from this source easily and uses it effectively to clean out unhealthy cholesterol deposits, even when cholesterol is being ingested in large amounts.

Alfalfa is rich in: Chlorophyll, octacosanol, beta-carotene, amino acids and is fifty percent protein!

Blackstrap Molasses
Blackstrap molasses is a food concentrate. It is a nutrient-rich food, not a sugar. It is one of the richest sources of minerals and vitamins found in sugar beets and sugar cane. The commercial processing of these sugars leaves us with a calorie-rich, nutrient-poor sugar product. Blackstrap molasses is the good part, with only a little sugar and lots of minerals and vitamins.

Blackstrap Molasses is rich in: Iron and calcium, and is also known as the richest natural source of potassium!

Bone Meal
Bone meal comes from beef and is a biological source of calcium, magnesium, zinc and other minerals that improve overall health. It provides protection against bone degeneration.

Bone Meal is rich in: Vitamin D, calcium, magnesium

Carrot
Carrot is a well-known "star" for health! Carrot is packed with beta-carotene (provitamin A) and is probably the most famous phytonutrient. There is substantial evidence that suggest strong cancer and heart disease preventative effects. It contains 42 health benefiting molecules, including carotenoids, coumarins, flavonoids, terpenes, phenolic acids, phthalides.

Carrot is rich in: Beta-Carotene, vitamin C.

Fishmeal
Used mainly in animal formulations for palatability, it has high amino acid content, and proteins essential for optimum health in animals.

Flax Seed
(Linum usitatissimum)
Flax is the richest vegetable source of Omega 3 essential fatty acids. It is also the richest known source of lignans, (a class of phytonutrients that have anti-fungal, anti-bacterial, anti-viral, and anti-carcinogenic properties. It is an exceptional source of dietary fiber, both soluble, and insoluble. Flax is high in boron, a trace mineral that helps the body hold onto calcium! The National Cancer Institute has chosen flax as one of the first five primary foodstuffs for study to determine health benefits of natural foods. From the Omega 3 essential fatty acids, the body produces series 3 prostaglandin's. These act on the cellular level in a variety of disease fighting ways, that include anti-clotting actions in the blood stream, anti-inflammatory responses that alleviate or prevent such auto-immune diseases such as: arthritis, psoriasis, and asthma. They are involved in mechanisms of transport and metabolism of both cholesterol and triglycerides that result in a strong lowering effect on both of these cardiovascular factors. Series 3 prostaglandins increase vitality, energy, and stamina due to their involvement in the body's process of oxidation, which, on a cellular level, is the way molecules are broken down to produce energy.

Flax Seed is rich in: Essential fatty acid Omega 3, soluble and insoluble fiber, and boron.

Garlic
Nature's antibiotic and enhancer of the immune system. Garlic was one of the National Cancer Institute first "five" foodstuff's being studied for multiple health benefits. Benefits being studied include the breakdown of blood clots, reduction of low-density lipoproteins (LDL) while increasing high density lipoproteins (HDL), alleviating asthma, reducing high blood pressure, and acting as an immune system stimulant. Garlic contains 35 phytonutrients including the allelic sulfides, terpenes, and phenolic acids.

Garlic is rich in: High density lipoproteins (HDL) and phytonutrients.

Glucosamine
Glucosamine is a naturally-occurring substance found in cartilage that stimulates the production of collagen, the protein that helps hold joints together. It can help build joint cartilage, as well as help joint mobility and joint range of motion. We use only the finest, high purity grade of Glucosamine Sulfate.

Kelp
Kelp has a salty taste and is used by many people in place of salt. It has a high content of natural plant iodine, which is absorbed into the body slowly, and therefore more safely, than chemical iodine. Iodine is necessary for proper functioning of the thyroid, which is essential for proper growth, energy and metabolism. Kelp contains calcium, potassium, magnesium, zinc and all trace minerals. It is nature's best source of natural iodine and has been used to aid the body in regulating the thyroid and pituitary glands, to help the body regulate body temperature (especially low body temperatures), and to aid in the function of the digestive and endocrine systems. It has been shown to prevent the growth of tumors, acting as an antibiotic, and contributing to the building of the cell wall.

Kelp is rich in: Natural iodine, calcium, potassium, magnesium, zinc and trace minerals.

Lecithin
A phospolipid that supplies choline, necessary to make the neurotransmitter acetylcholine (brain and nerve function). It is also known in medical circles as an "edible detergent" which breaks up fats into small droplets, of primary importance in keeping cholesterol soluble. Lecithin is in every cell membrane and is involved in electrical phenomenon and membrane fluidity on the cellular level.

Liver
Liver stores vitamins and minerals for the body. It is especially high in vitamin A! Liver is the most nutrient rich meat and it also detoxifies itself and the rest of the body. It converts strong toxins to less toxic forms and puts these into the intestine for their removal from the body.

Liver is rich in: Concentrated forms of vitamins, like vitamin A.

Nutritional Yeast
Nutritional yeast is traditionally known as a "super" food. There are various yeasts available. Nutritional yeast is more nutrient rich than brewers yeast and tastes a whole lot better. Yeast is an excellent energy booster between meals has been known to help sugar metabolism. Because of the nutritional importance, this has been reported as beneficial for eczema, heart disorders, gout, nervousness and fatigue. This also enhances the immune system, and regulates the body's natural balance of yeast.

Nutritional Yeast is rich in: B vitamins, sixteen amino acids, fourteen+ minerals, including iron, potassium, calcium, and chromium, ten vitamins, and is sixty percent high quality protein.

Omega 3
Omega 3 is an essential fatty acid necessary for optimum health! When foods like fish or flax Seed are eaten, Omega 3 fatty acids produce series 3 prostaglandins in the body.

Omega 6
Omega 6 fatty acids are critical to balancing the ratio of Omega 3 to 6! Without a proper balance, the bodies quickly loses the ability to achieve optimum health, and may even have detrimental effects if the intake of Omega 3 is not balanced with Omega 6.

Oyster
Primarily included in the pet formulas for palatability. It is a rich source of zinc.

Rice Bran
Rice bran is really the "brown" parts of rice; the parts that usually are processed out of the rice and that contain vitamins, minerals and fiber. Rice bran is also a source of naturally occurring antioxidants.

Sprouted Green Barley
This is another "green" food, a class of exceptionally nutritious foods that have high concentrations of vitamins, minerals, proteins, enzymes, chlorophyll, and mucopolysaccharides. Barley green contributes in many ways to the body's healing ability, including benefits against allergic reactions, inflammation, high blood pressure and detoxification.

Sunflower Seed
Besides being a nutrient- and fiber-rich seed, sunflower is included to bring the Essential Fatty Acid ration to a more optimum level by providing the Omega 6 Essential Fatty Acid.
