DEAR DR. GOTT: A while back, you published an article about eye twitching. I, too, have had eye-twitching problems and did consult a doctor. He suggested getting a shot in my temple, but I declined, it being so close to my eye. I read somewhere that soy was good for the nervous system, so I bought lecithin concentrate, 400 milligrams, and now take one in the morning and one at night. As long as I take them, I do not get the twitching. If I stop taking them, within a day or two, it starts again. I’ve been using the lecithin for a number of years now, and just the two tablets are still sufficient. Thank you for your informative column.
DEAR READER: There are two main types of lecithin: egg and soy. Soy lecithin is extracted from soybean oil and used as a food and drug additive, typically an emulsifier. It is becoming more popular as a dietary supplement. It is purported to benefit many conditions, such as high cholesterol, gallbladder disease, Alzheimer’s disease, eczema, anxiety and more.
Soy, in general, has not been studied extensively in regards to claims that it will treat, improve, or cure certain health conditions. Soy protein is known to be a good alternative to animal protein and is beneficial to maintaining health, however.
There are no established dosing guidelines simply because not enough research has been done. Some studies have noted diarrhea, nausea and abdominal pain and fullness as side effects.
If it works for you, stick with it. Others who want to try this should speak with their physicians first. Be sure to keep track of when the supplement was started and make note of any improvements, side effects or reactions, even if they seem unrelated. This is especially important if you are on other medications, over-the-counter or prescription, as well as other supplements, vitamins or herbs.
