  • Nutrients: L-Tryptophan

Feature Ingredients

  • L-Tryptophan: An essential amino acid, used by the brain to produce serotonin that promotes optimal mood and sleep.

A factor in the maintenance of good health. Helps the body to metabolize carbohydrates, proteins and fats. Helps in tissue formation. Helps to prevent vitamin B6 deficiency. A source of the essential amino acid L-Tryptophan.

Tryptophan is an essential amino acid, used by the brain to produce serotonin, a necessary neurotransmitter which transfers nerve impulses from cell to cell, and is responsible for normal sleep. 

Functions of tryptophan is complemented by B vitamins, for example vitamin B-6 prevents undesirable degradation and loss of tryptophan, and other b vitamins contribute to the health of nervous system and mood.

As tryptophan is a precursor of serotonin production, it is beneficial for conditions such as depression, insomnia, mood disorders, stress, and hyperactivity in children. A lack of tryptophan and magnesium may contribute to coronary artery spasms or irregular heartbeats.

L-tryptophan helps normal function by being available for the body to use as needed. Although tryptophan is found in foods, such as brown rice, cottage cheese, turkey, peanuts, and soy protein, its absorption is very little due to competing with various other amino acids for uptake.
