An essential amino acid complex for dogs and pet birds. Amino Plex 5000 has shown excellent results in the production of enzymes and hormones. Amino Plex 5000 is excellent for supplementation of the body's amino acids needed for muscle building and performance animals.Amino acids are the building blocks of protein and the facilitators of metabolism. A deficiency in any of the body's essential amino acids means a serious deficiency and loss of the body's ability to efficiently produce and process proteins, or muscle and connective tissue. Our pets, like humans, produce about 10 of the 20 or so essential amino acids needed for the proper body function; the rest must be supplied by the food that is eaten. Many essential amino acids are found in commercial pet foods, but many pet foods are deficient in the most essential amino acids, resutling in a need to supplement the missing amino acids with a quality dietary supplement like Amino Plex. Unlike fat or starches, amino acids are not stored in the body for later use and must be replenished daily through the food taken in.
