Essential Amino Acids For Dogs & Cats


Protein is crucial to providing your best friend with a healthy and balanced diet. Protein and amino acids are vital to optimal function, health and immunity.

There are three macronutrients in nutrition – protein, fat, and carbohydrates. Proteins are the structural components of organs, soft tissues, muscle fibres, skin, hair, nails, and blood. They can function as enzymes, hormones, and antibodies. Proteins are used to transmit and store molecules throughout the body. Excess protein that surpasses the need for muscle tissue maintenance is used for energy.

NutriFlex™ Collagen has a unique amino acid profile, unlike any other source. NutriFlex™ Collagen contains 18 amino acids including 8 essential amino acids (essential amino acids cannot be produced by the body and can only be derived from the diet). Amino acids are the building blocks of tissues and the primary component of proteins. Glycine, Proline and Hydroxyproline are key to any collagen’s anti-ageing, vitality and mobility boosting benefits and these represent around 50% of NutriFlex™ Collagen’s total amino acid content; the Glycine and Proline concentration in NutriFlex™ Collagen is 10 to 20 times higher than in other proteins. As a result, NutriFlex™ Collagen offers health benefits that cannot be found in other protein sources.

Deficiencies of any essential amino acids over time can lead to premature ageing and health problems.

If protein levels are higher than needed, any excess will be excreted as urine. If very high levels of protein are fed for an extended period, excess protein not used for energy can be stored as fat. Protein deficient diets may lead to fatigue, weakness, weight loss, and a rough and dull-looking coat.

Each daily scoop of NutriFlex™ fortified collagen contains 18 naturally derived amino-acids with a unique abundance of glycine, proline and hyroxyproline.


Amino Acid


  1. Maintains lean muscle mass into old age
  2. Supports improved joint health and function
  3. Aids digestion and gut health
  4. Boosts immunity
  5. Improves brain function
  6. Accelerates recovery from injury or surgery


Amino Acid


  1. Promotes wound healing and recovery from injury or surgery
  2. Supports digestive health
  3. Helps prevent joint pain
  4. Improves cardiovascular health
  5. Boosts metabolism and fights inflammation


Amino Acid


  1. Promotes joint function
  2. Improves cardiovascular health
  3. Promotes muscle strength and repair
  4. Increases natural collagen production


Amino Acid


  1. Boosts immunity
  2. Aids digestion and improves gut health (protects against "leaky gut")
  3. Improved muscle recovery from strenuous exercise
  4. Medical conditions and low-protein diets impact negatively on your pets glutamine levels. Critically ill patients have a higher requirement for glutamine because, in high times of stress, the body is unable to synthesise sufficient amounts of this vital amino acid.


Amino Acid


  1. Protects against oxidative stress and free radical damage
  2. Regulates blood sugar and helps prevent hypoglycaemia
  3. Boosts urinary tract health and helps prevent kidney stones
  4. Boosts immunity and fights inflammation














* Essential Amino Acids that cannot be synthesised by the body and must be supplied in the diet.

Food Sources of Amino Acids

High Quality Proteins

Protein quality is determined by the efficiency of amino acid conversion to body tissue. The efficiency of amino acid conversion is dependent on the protein source, the concentration of essential amino acids, and the availability of the nutrients. Proteins that provide optimal amounts of all essential amino acids are classified as complete proteins or high-quality proteins. NutriFlex collagen is 97% protein that has been hydrolysed to promote maximum absorption of amino acids in a minimum of time.

High-quality proteins with the most abundant sources of essential amino acids are animal products such as muscle meat, raw meaty bones, and organs. beef, lamb, pork, chicken, eggs and fish are a few examples of animal proteins that all provide all essential amino acids to create a complete diet. The number of amino acids present in each product will depend on multiple factors including animal type, fat content, the diet the animal was fed, processing conditions, storage conditions, and time in storage.

  • Muscle Meat — is abundant in essential and conditional amino acids and should be the main ingredient for home-cooked pet food diets
  • Oily Fish — contains high levels of essential and conditionally essential amino acids in addition to their fatty acid benefits
  • Bone Broth — In addition to muscle meat "Bone Broth" is another rich source of essential Glutamine. NutriFlex Collagen provides all the goodness of bone broth in a powdered concentrate.
Hydrolysed Gelatin

Aids gut health and digestion

Just like collagen, gelatin is also beneficial in the prevention of intestinal damage and improving the lining of the digestive tract, thereby preventing permeability and leakage into the bloodstream, which triggers inflammation.

Gelatin can improve the body's ability to produce adequate gastric acid secretions that are needed for proper digestion and nutrient absorption. Glycine from gelatin is important for restoring a healthy mucosal lining in the stomach and facilitating with the balance of digestive enzymes and stomach acid. Insufficient digestive enzymes and stomach acid can cause common digestive problems such as nutrient deficiencies, acid reflux, bloating, indigestion, as well as anemia. Gelatin is capable of absorbing water and fluids, which can help prevent fluid retention and bloated stomach while improving constipation.

Hydrolysed Gelatin

Fuels liver detoxification

Gelatin is rich in the amino-acid glycine (33%), which is essential for detoxification. Without enough glycine the body won’t make enough glutathione, an important step in liver detoxification. Glycine can also help regulate insulin and prevent hypoglcemia, help fight inflammation and reduce discomfort from stiffness and painful arthritis.

Hydrolysed Gelatin

Fights adrenal fatigue

When under extreme stress or pain the body requires more minerals and amino-acids. Gelatin is protein-rich and an excellent source of amino acids which can help invigorate the kidneys, adrenals and bladder which helps alleviate stress and manage cortisol levels more effectively.
