L-LYSINE – Essential Amino Acid. Build topline muscle and boost immunity.



L-lysine (Monohydrochloride 98.5%). An essential amino acid.

Equine feed supplement for improved protein availability, muscle health, immune support, hoof & skin health and performance.

Lysine is an essential amino acid most often deficient in the diets of horses. Lysine is found in a wide variety of tissues, hormones, and cells throughout the body. Myosin and other muscle proteins contain large amounts of lysine. Proteins that require lysine include the collagens and elastins that make up bone matrix, tendons, skin, and articular cartilage.  Keratin protein in hoof and hair also requires lysine. Inadequate intake of protein or required amino acids by horses may lead to reduced feed intake, body tissue loss, poor coat, and  hoof growth. It can also contribute to decreased growth and development in young animals.

Using  Progressive Earth L-lysine at times of stress is key to calcium absorption, boosting the immune system and supporting the body’s production of hormones, enzymes and antibodies.

L-lysine is commonly considered a useful nutritional supplement for Herpes virus outbreaks in people. A common disease of the modern day horse is Equine Rhinopneumonitis (EHV-1 and EHV-4), which is caused by a Herpes Virus. Rhino is the inflammation of the respiratory tract caused by the Herpes virus that lives in the horses body and can not be cured. Highly stressful situations such as training, travelling, shows, other diseases or infections and ulcers for example, can cause an outbreak to occur.

Supplementing the immune system with L-lysine can be very beneficial to optimal health and performance.
