Tryptophan Amino Acid - Bulk Raw Material Supplier

Tryptophan is an amino acid needed for normal growth in infants and for nitrogen balance in adults. It is an essential amino acid. This means your body cannot produce it, so you must get it from your diet.

L-Tryptophan is one of essential amino acids and the forth limiting amino acid in animals diets,which means it could not be synthesized by the body,in addition,dietary supply  through feed materials is usually insufficient.  

The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency,and slow growth rate.

Considering L-Tryptophan playing a key role in growth performance and feed efficiency, it is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible tryptophan requirement of animals, especially piglets, sows and poultry etc.


  • Increase the feed intake.
  • Reduce crude protein level in diets without impact on animal growth performance, particularly low protein diets for post-weaned piglets.
  • Enhance the overall growth, even under stress conditions for immune system,such as depressed, vaccination and deteriorated hygiene conditions.
  • Save the entire cost of feed.
