0001UCLL Uckele L-Lysine

SKU: 0001-llysine Category:




L-Lysine is the most commonly deficient amino acid in the equine diet important for the maintenance of healthy muscle bulk. Lysine is required to manufacture L-Carnitine, a carrier required to burn fat for energy and an important component of collagen, the major protein in connective tissue.


L-Lysine is an amino acid, the basic building unit of proteins. Amino acids are hooked together like beads on a chain to form proteins, according to sequences encoded in an animal’s DNA. Every bead on the chain is an amino acid.

L-Lysine is an essential amino acid, meaning the horse’s body cannot manufacture it and must get all that it needs from the diet. It is also a limiting amino acid. It is called limiting because if amounts are not adequate, protein synthesis won’t be able to proceed normally. Assembly of proteins like beads on a chain will stop if a needed amino acid is not present. L-Lysine is also the amino acid most likely to be deficient in the horse.

Typical equine adult diets without supplemental L-Lysine may be 5 to 10 grams short of requirements. Pregnant, lactating and growing animals have greatly increased requirements. Consult a professional for guidance on supplementing these groups.

A common manifestation of suboptimal L-Lysine intake in horses is poor muscle development but L-Lysine deficiency also has a negative impact on regulation of Calcium metabolism, immune function, hoof and tendon/ligament health, even vision and mood. Adequate L-Lysine is required for normal growth.

L-Lysine is also an important component of collagen, the major protein in connective tissue. Connective tissue forms the sheaths and tissue planes that define the body and hold it together. Specialized collagen forms tendons and ligaments. Collagen forms the basis for everything from the whites of the eyes to umbilical cords.

L-Lysine supplementation has also been reported to have a beneficial effect on immunity and gastrointestinal health.
