What is L-Tryptophan?

L-tryptophan is an essential amino acid made from proteins during digestion by the action of proteolytic enzymes. Tryptophan can only be obtained through food or supplementation and cannot be produced within the body.

Tryptophan is a precursor and a vital element for neurotransmitters serotonin and melatonin. These chemical messengers transport nerve impulses from one cell to another. The brain will not function properly without sufficient amounts of these neurotransmitters.

The body also utilizes tryptophan to synthesize vitamin B3 (niacin). Many nutritionists believe that as long as the body gets enough tryptophan-rich foods it will be able to produce adequate amounts of niacin.

For tryptophan to be able to carry out its bodily functions effectively, vitamin B6 is also needed. Other nutrients that are required include vitamin C, folate (vitamin B9) and the mineral magnesium.

Rich sources of tryptophan are chocolate, oats, bananas, dried dates, milk, cottage cheese, meat, fish, turkey and peanuts.

Health Benefits of L-Tryptophan

Tryptophan is needed to produce serotonin in the human body. Serotonin is one of the key brain chemicals involved in regulating mood. Serotonin levels play a key role in the regulation of anxiety, depression, appetite, sexual behavior and aggression.

This amino acid is present in high levels in turkey meat and has long been said to be the reason people get sleepy after a big turkey dinner. Actually, tryptophan is also present in high levels in other meats too.

Tryptophan is required to synthesize niacin (vitamin B3) and needs vitamin B6, biotin, vitamin C and zinc to manufacture the enzyme for conversion.

Since a serving size of 1/8 teaspoon equals 180 milligrams, then 3/8 teaspoon equals 540 milligrams. For a 500 milligram serving, take a little less than 3/8 tsp.

Potential Side Effects of L-Tryptophan

Tryptophan is safe at suggested serving sizes. Rare side effects include heartburn, stomach pain, belching and gas, nausea, vomiting, diarrhea and loss of appetite. In larger quantities, side effects can include agitation, confusion, diarrhea, fever, overactive reflexes, nausea, hypomania (a mild form of mania, characterized by hyperactivity and feelings of well-being), poor coordination, restlessness, sweating, and vomiting. CAUTION: Persons suffering from severe depression or anxiety should talk to a physician before taking L-Tryptophan as a dietary supplement. Talk to your doctor if you are taking, or have taken medications to treat stress, anxiety or depression within the last 90 days!! Avoid combining L-tryptophan with serotonin-influencing agents such as 5-HTP or SSRI drugs such as Prozac and Paxil.
People with liver or kidney disease should not take this or any other amino acid supplement without first consulting their physician.
