Product Info:

Great for horses that have hyper-excitability or nervous, confused and erratic behaviour and

 has been used in the treatment of Equine Headshaking Syndrome.

Use for daily training, competition nerves, changes in seasonal behaviour (spring) helps with education and equine transportation. 

L Tryptophan is an amino acid necessary for normal growth in foals and for nitrogen balance in adult horses. It is an essential amino acid, which means the body cannot produce it and it must be obtained from diet.


L Tryptophan is low in dried pasture and grain. It is used by the body to help produce niacin and serotonin. Studies have shown that serotonin may increase sleepiness or sedation and decrease aggression, fearfulness, mania, insomnia and pain sensitivity. l Tryptophan deficiency is thought to increase nervousness and excitability in some horses. Management considerations could also help calm the excitable horse.

B-Complex Vitamins


Athletic animals should be given a range of vitamins, minerals and amino acids in their diet to maintain optimal health. B-Group vitamins are intimately involved in energy metabolism - the conversion of food into fuel. They also stimulate the appetite and are involved in blood formation. Unfortunately most B-Vitamins are not stored in the body and need to be replenished daily.

Athletic animals, which exercise regularly and strenuously, have far greater requirements for vitamins, amino acids and minerals than non-athletic animals. Maximal exercise has been shown to reduce B vitamin levels, and suppress the blood counts of athletic animals. Many athletic animals have a low red blood cell count. Less red blood cells means less oxygen going to the muscles which means they cannot perform at their peak. The B complex vitamins and the trace minerals iron, copper and cobalt are required for the production of normal red blood cells. The need for B Complex Vitamins are increased in athletic animals in training and under stress.

B1-Thiamine is necessary for the proper function of the heart and nervous system. Combines with phosphorus to form thiamine pyrophosphate (TPP) necessary for metabolism of protein, carbohydrate, and fat; essential for growth, normal appetite, digestion, and healthy nerves. A deficiency of thiamine can cause weakness, fatigue, confusion, and nerve damage.

B2 - Riboflavin helps muscle cells produce energy. It is required by the body to use oxygen and the metabolism of amino acids, fatty acids, and carbohydrates. Riboflavin is further needed to activate vitamin B6 (pyridoxine), helps to create niacin and assists the adrenal gland. It may be used for red blood cell formation, antibody production, cell respiration, and growth. Vitamin B2 is required for the health of the mucus membranes in the digestive tract and helps with the absorption of iron and vitamin B6. Although it is needed for periods of rapid growth, it is also needed when protein intake is high. Riboflavine (Vitamin B 2) works with the other B vitamins. It is important for body growth and red blood cell production.

Vitamin B-6 is important for health of the blood vessels and red blood cells. Pyridoxine hydrochloride (Vitamin B 6) plays a role in the synthesis of antibodies by the immune system. Antibodies are needed to fight many diseases. Vitamin B 6 helps maintain normal nerve function and also acts in the formation of red blood cells. It is also required for the chemical reactions needed to digest proteins. The higher the protein intake, the more the need for vitamin B 6. Deficiency of this vitamin can cause irritability and confusion.

Magnesium in the body serves several important metabolic functions. It plays a role in the production and transport of energy. It is also important for the contraction and relaxation of muscles. Magnesium is involved in the synthesis of protein, and it assists in the functioning of certain enzymes in the body. Magnesium deficiency symptoms include muscle weakness, fatigue and hyper-excitability.

If dietary levels are low, supplementation with Hush with Tryptophane from Equine Health Science may help counter symptoms of hyperexcitability, nervousness, irritability and confusion.
