Until 1990 tryptophan was by far the most used natural sleep aid on the market. In 1990 the United States Food and metabolism booster drug; https://www.courierherald.com, Administration pulled all the tryptophan from store shelves because of an unexpected outbreak of eosinophilic myalgia syndrome that occurred among some men and women who had taken the sleep aid. Once the United States banned the substance several other countries shortly followed. Ultimately nearly 5 thousand people reported getting sick and twenty 7 people died from the serious illness. The symptoms included muscle pain, severe joint pain, along with weakness. A long investigation found that the problem was a contaminated batch which was made by a Japanese business named Showa Denko KK, which had recently changed a production process to incorporate genetically engineered bacteria.  The ban remained in effect until 2001.

In February of 2001, the FDA removed the ban on selling tryptophan, but kept an importation restriction.  This is the declaration that they released:

“Based on the scientific evidence which is available at the current time, we can’t figure out with certainty that the occurrence of EMS in vulnerable persons taking in L-tryptophan dietary supplements derives from the material of L tryptophan, an impurity found in the L tryptophan, or perhaps a combination of the 2 in association along with other, as yet unknown, outside factors.”

Since 2002, tryptophan is available again in the Country and no reports of Eosinophilic myalgia syndrome were reported.  There are certainly manufacturing businesses currently producing high quality tryptophans. I believe it’s safe. It’s a precursor of the sleep-inducing substances serotonin and melatonin. This means it is the raw material which the brain uses to build these relaxing neurotransmitters. By taking it in supplement form we are generating much more available to generate the neurotransmitters which are utilized to induce deeply rest.

Melatonin is presently the hottest and well respected of the organic sleeping aids offered. It’s a far more direct precursor to serotonin than is tryptophan. Melatonin also is much cheaper. I commonly will recommend melatonin to the clients of mine while the very first thing to try to resolve sleep problems naturally. But one thing I’ve found is the fact that for reasons unknown the people that do not respond well to melatonin can often think it is effective. For countless men and women it’s a valuable natural sleep aid, but tryptophan has never really regained the recognition it previously enjoyed just before 1990.
