L-Tryptophan and Weight Loss

With so many weight loss supplements available on the market, how do you choose? L-Tryptophan, widely known for its benefits in treating depression and mood disorders, is gaining popularity as an aid for weight loss. It comes with virtually no side effects and is naturally-occuring.

Background

• The human body needs eight amino acids to function. L-Tryptophan is one of them. It occurs naturally in many foods, including turkey, milk, eggs, chocolate, bananas, red meat and other foods with protein. You can also purchase L-Tryptophan as an herbal supplement in pill or powder form from nutritional stores or online.

How It Works

• L-Tryptophan reduces cravings for carbohydrates and sweet foods. It works by increasing serotonin levels in the brain. Serotonin helps regulate metabolism and appetite, reducing cravings and helping a person determine when they are hungry and when they are not.

Other Uses

• L-Tryptophan is often used to help treat depression and bipolar disorder. It can also act as a mood-enhancer to soothe anxiety, decrease panic attacks and promote better sleep. It can also be beneficial to those who are trying to quit smoking, or quit drinking alcohol. L-Tryptophan can help balance your mood while you withdraw from addictions.

Warning

• L-Tryptophan has very few side effects --- especially when compared with other weight-loss products. However, if you take too much, you may experience psychotic symptoms, so consult your doctor or health professional on the correct dose for you. L-Tryptophan supplements are not regulated by the FDA. Ask your doctor if it is OK to take this supplement along with any other medications you are currently taking.

Cost

• L-Tryptophan costs about $20 for 90 capsules. This may vary depending on where you purchase the product.

History

• In 1989, the FDA banned L-Tryptophan. At the time, it was thought to have caused a deadly flu-like illness called Eosinophilia-Myalgia Syndrome, or EMS, after a large outbreak. All of the victims were taking L-Tryptophan. Later, experts concluded the disease was caused by a contaminated batch of L-Tryptophan from Japan. The ban was eventually lifted in 2002, and the supplement is now available again in the U.S.
