The action, which started in late November, follows the FDA's nationwide recall of non-prescription supplements of the amino acid used for sleeping disorders, premenstrual syndrome, depression and stress.

The FDA is planning to restrict health claims of nutritional supplements such as we find in health food stores and pharmacies. Currently, a vitamin or food supplement can (and frequently does) make healing claims that have absolutely no scientific evidence to support them. Remarkably, the FDA has been able to do nothing to stop this. Why? Because our congressman, Elton Gallegly, authored and pushed successfully a bill to prohibit the FDA from doing the job it should do. He authored a bill that prohibited the FDA from taking stronger steps to protect the public for a one-year period.

Over the summer, the 37-year-old woman had been sail boarding and winning tennis tournaments. Then she began to experience insidious pains in the temples and jaws. Later the pain spread throughout her body. It became so intense that "it hurt to put my sunglasses on," she recalled.

Identifying impurities in L-tryptophan nutritional supplements associated with the eosinophilia-myalgia syndrome has been far easier than learning how to treat those afflicted with the painful and potentially fatal disease.

IT'S a Thanksgiving Day ritual -- lolling around after dinner complaining that the turkey has made you sleepy. This myth (yes, it's a myth) emerges from the fact that turkey contains the amino acid tryptophan, which can play a role in sleep. But to have this effect, tryptophan must be taken on an empty stomach -- and in much higher doses than one can consume in food. It may, however, have another effect. A new study suggests this natural substance may have an effect on the immune system.

If there is a golden rule of nutrition, it is a simple one: Too much of anything is bad for you. Yet, when it comes to amino-acid nutritional supplements, Americans seem to cling more to the creed that if a substance occurs naturally within the human body, one can never have too much of it. That philosophy resulted in the development of an estimated $150-million-a-year market for the amino acid tryptophan in the United States over the last few years.
